Figured cutting of plywood at home
If you follow the instructions in everything, your foam rubber will be cut perfectly. So let’s go:
- Since we decided to cut the foam rubber on a lining, and not on linoleum or parquet, the first thing we do is lay it. Plywood first, then a sheet of cardboard.
- On top we lay a layer of foam rubber that we want to cut. We make sure that the line of the future cut falls on the lining.
- We take a ruler and, in accordance with the given dimensions, draw a line along which the future cut will pass.
- We remove the ruler. If we cut along a ruler and press down on it at the same time, then the cut will turn out to be even, but the edge will be the same depressed as in the case of the scissors. If you decide to cut along a ruler, then in no case press on it.
Good advice on how to cut the foam so that the edge is perfect. If you feel that the knife has begun to make peculiar hooks during the wiring, it means that in some place the blade has become dull and, without cutting through, begins to tear the foam rubber, forming a strip of foam burrs. In this case, immediately replace the blade with a new one. It is best to do this without waiting for this to happen. We made five or six wires, changed the blade. They can then be used again for any other purpose, but they will no longer be suitable for cutting foam rubber. A simple cutting of foam rubber with a knife is clearly shown in this video.
What’s the problem with scissors?
The problem is that when cutting with scissors, the structure of the foam rubber along the edges of the cut is broken. The edges are depressed and no longer straighten to their original position. So scissors for even cutting will not work either.
How to cut foam rubber at home: expert advice
Foam rubber is a great thing. Soft, comfortable and harmless. Most often, mattresses and padding for upholstered furniture are made from it. It comes in varying degrees of rigidity and thickness. But regardless of what elasticity and thickness it has, it should only be cut with a knife. How to cut foam rubber with a knife, and why you need to do it only with this tool, you will learn from this article.
Preparing tools for cutting foam rubber
So, how to cut foam rubber at home so that the edges are as smooth as possible and close to those obtained during production cutting? To do this, you will need to prepare the following tools and consumables:
- Actually, the foam itself, which we are going to cut.
- Lining for foam rubber, which we will cut. It is clear that if we lay it out on linoleum or on the parquet floor of an apartment, these same materials will end, since they will all be scratched by a knife. As a lining, it is best to use a sheet of plywood with cardboard laid on it, so that the tip of the knife does not blunt against the hard plywood. Cardboard can be used by opening any suitable size cardboard box.
- It is desirable to have a knife from the category of construction. They are also called linoleum knives. He comes with a whole clip of removable blades, which can be changed in case of dullness. It is better to use a branded European rather than a Chinese knife, since the steel of the “Chinese” is of low quality, and such a blade will become dull after the very first wiring.
Bad tips for thin wire
It is better not to listen to these advice. Even if the cutting of foam rubber takes place on the street, you risk breathing in the most dangerous toxins so that you will ruin your health at once. The thing is that foam rubber is not ordinary plastic. To give it a foamy structure, various kinds of toxic impurities are added to the polymers, which are absolutely not dangerous in the usual solidified state and at room temperature, but instantly turn into the strongest poison when heated.
Yes, in production this material is cut by means of hot nichrome threads. But there people work in protective clothing and respirators, or even stay in a protected operator’s booth with an excellent hood. And since you are going to cut the foam rubber at home, in the absence of such means of protection, you risk poisoning not only yourself, but also your loved ones.
Plus, this method is only suitable for straight cuts. To make a curly one, you still have to take up a knife.
about curly cutting
How to cut foam rubber smoothly along curved lines? Here everything is the same as in the case of straight cutting. The only thing is that the angle of inclination of the knife towards you should be increased to the maximum, otherwise the cut out parts will “mow” a little along the edges, as if you were holding the plane of the knife blade in relation to the plane of the foam rubber non-vertically. That’s all. Nothing complicated. The main thing. have patience and a branded knife, and the edges of the cuts you get as a factory.
Preparation for work
Even at this stage, a lot can go wrong. The mistake can be made by connecting the power supply. Or, in general, something can be assembled wrong, and everything will go to dust after connecting the electricity. Now many systems contain emergency “foolproof”, but there are any.
This is how sometimes you have to deliver equipment to the installation site.
Problems may not be technical in nature, for example. the dimensions of the equipment were poorly checked, and that’s it. it doesn’t fit through the door. What to do? Disassemble the machine? Not always possible. Expand the doorway? Difficult too.
Hood and cooling connection (technical design, budget). A laser cutter requires more than just energy to operate. Extraction and cooling are also required. The hood can be any, depending on the specifics of the device. The shorter the exhaust pipes, the better (if possible, of course). If the cooling is water, a supply of distilled / purified water is required. You need to think about installing the hood and cooling in advance, and not after the laser cutter has already been purchased.
Noise and smell. A working laser cutter, its cooling and extraction make a lot of noise. In addition, there will be a smell, no matter how good the hood is. The system can work for hours, so it is worth choosing the appropriate place. one where the cutter will not interfere. It is best to take care of all this in advance, too. The hood should really remove the air with the vapors of the processed material from the room, and not drive it in a circle.
Despite the advice in the style of KO, quite a few beginners forget about something, something they neglect. And then, after installation, it can be excruciatingly painful due to an unresolved problem in advance.
Beginning of work
Lack of a compressed air supply system to the cutting site. If there is no such system or it has failed, then the flammable material with which the cutter is currently working may well catch on fire.
When air is supplied to the place of work, all vapors of waste material go away, and the temperature does not have time to rise too quickly.
Using proprietary software. An inexpensive laser cutter from China is likely to run its own proprietary software. This is, in most cases, proprietary software written by the hardware manufacturer, and unexpected problems can arise with this software. These are CAD programs that prepare cutter models that are incompatible with the laser system software. Some files may not be imported, and some may not be exported. This greatly slows down the work, and the problem itself in some cases can ruin the entire workflow. If something like this happens, then you can think about changing the CAD program (no matter how convenient it is) or replacing the controller.
An error in the characteristics of the working material. In some cases, the characteristics of the material purchased for work (plastic, metal, etc.) may differ significantly from reality. And then the printer configured for one mode of operation can ruin the entire project due to the discrepancy between the manufacturer’s described and real parameters of the material.
Skin test sample after drawing
Therefore, you should not put into work (for example, start engraving) a working sample. it is better to check it on a test sample, which is not a pity to spoil.
Laser Cutting: Avoiding Cutter Failure?
A Few Tips for Beginners
CNC laser cutting machines cannot be called cheap, but an average entrepreneur can already afford such a system. Some models from China cost about 4000. You can do everything with a laser. cut out the cases of devices, individual structural elements, apply images on metal, wood, leather and plastic.
But the presence of computer control does not mean at all that the operator can rest on the couch with his favorite book in one hand and a bottle of beer in the other. In order for the result of the work to meet all the criteria for success, the operator needs to make a lot of effort. What stages of cutting should you focus on? A master who has been working with various types of laser cutting systems for quite a long time tells about this.
The working process
We leave the device unattended. As discussed above, the operator must keep a close eye on the system at all times. If this is not done, then the device, due to some failures (the most unexpected), may completely fail:
No matter how high-quality and safe the cutter is, no matter what protection technologies are used in it, there is always the possibility of ignition of individual elements of the machine or work material. This is true even for those materials with which the owner of the machine previously worked without problems. The software or the electrical system of the system could fail. The servo may fail, or the belt may break. If something like this happens, the operator can de-energize the machine, and the problem will not have any consequences.
Incorrect focusing of the laser. In order for the result to be perfect, the lenses must also be perfectly adjusted. If something is even slightly wrong, the work can go to pieces.
Surface protection. It is better to apply a pattern on the surface with the use of protection. This can be a special film that will prevent the surface near the working area from warping or changing color. Many types of cutter plastics are already sold with this protection. But there is another problem here.
Inability to remove the protective film at the end of the work. It is easy to protect the surface, but you also need to remove the protection after work. Under the influence of the laser, the film can sometimes fuse with the sample, resulting in a sloppy appearance. Such cases need to be foreseen in advance, considering the course of work.
Unique material properties. The characteristics of some types of materials can affect the cutting process and be reflected in the final result. For example, working with a mirrored surface is a problem. The fact is that the laser used for engraving reflects off the mirror surface, and the image is double.
Garbage removal. Usually, laser cutting does not produce too much debris. But still there is such garbage, you cannot completely get rid of it. And if it is not removed in time, it can damage the surface of the material. particles of debris can catch fire or fuse with the product.
Release of harmful substances. PVC is an example. When cutting PVC with a laser, chlorine is released into the air. As you know, this is a heavy gas, and it will sink into the bowels of the machine. Chlorine is corrosive. The gas interacts with a wide variety of materials, including insulation, rubber gaskets, etc.
If everything goes well, this does not mean that the result will be optimal.
Let’s say everything went well, there were no failures. But before you rejoice at a job well done, try to check if everything is really close to ideal.
Everything is great here thanks to a previous skin test.
The fact is that some materials exhibit unusual properties (deformation, color change, etc.) during laser heating. Due to these properties, the material can change its appearance in the most unexpected ways. Problems can be of a different nature:
Deformation of the plastic. For example, very thin plastic deforms when exposed to high temperatures. In this case, a relatively flat surface heated to a certain temperature can help, where you can straighten the plastic.
Sharp edges and burrs. Some types of plastic can leave both sharp corners and burrs. In this case, it is worth using mineral solvents to solve the problem.
Contamination of the current working sample with particles left on the desktop from the previous project. It is necessary to ensure that the working area of the machine is clean.
Hidden costs. Yes, it often happens that a laser cutter entails additional costs, and considerable ones. All this the user begins to take into account already with experience, at the beginning, the majority have unnecessary expenses. Excessive material consumption, significant increase in energy consumption, etc. You should try to calculate all this even before purchasing the system.
Unwillingness to change anything
This is the most common problem. “And so it will do”. this saying becomes a call to action for many of us. It can lead to excessive costs, unsuccessful cutting results, and customer dissatisfaction. If you decide to use laser cutting like a professional, then you should act like a real master. The car needs to be monitored and looked after. It is necessary to follow many of the rules for operating a laser cutter and try not to break these rules. And then everything will be fine.
Well, now it remains to wish you successful work!

Laser wood cutting at home: features of the choice and use of installations. Features of the workflow
Equipment for laser cutting wood is not common, but every year its popularity is growing. The fact is that earlier such machines were very expensive, but with the development of technology, their price dropped significantly, and they became available to a wide range of users.
It is important to choose a high-quality option so that it allows you to perform the processes you need, but correct operation is no less important, and this review will be devoted to these issues.
Criterias of choice
First of all, we recommend paying attention only to the products of companies that have proven themselves in the market, since it is very important how well the equipment is produced. Using unreliable options can even be dangerous, so it’s best not to chase questionable savings.
Of the important nuances, the following can be distinguished:
- The power of the laser, its performance and the speed of material processing directly depend on this, usually manufacturers produce a whole line of equipment with different characteristics for various needs.
- The size of the table is also very important, since if you are working with large sheets, then they must be completely located on the work surface. Decide in advance on this indicator so that when choosing to know which solution is optimal for you.
Cutting Large Sheets With A Circular Saw
For small jobs, you can purchase compact equipment that can be located in almost any room
- Laser cutting on wood can be carried out on structures of different configurations, so it is desirable that the working surface has the function of height adjustment.
- All components and supporting structure must be made of durable materials, this is very important to ensure the reliability of the machine. In addition, all moving parts must move clearly, without backlash and slippage.
- It is very important to have high-quality and simple software, since any failures can lead to equipment downtime.
Features of the workflow
Wood laser carving is carried out in small installations that are easy to use
To prepare the equipment, you need to carefully study all the recommendations given by the operating instructions. In addition, the first launch is best done with a specialist who should teach you the basics.
In general, do-it-yourself laser cutting of wood is not difficult and includes the following steps:
- The computer prepares a model of the future product, which can be both two-dimensional and three-dimensional.
- Further, all data is entered into the equipment computer, and it independently calculates all the necessary operating parameters.
- A workpiece of the required size is fastened and carefully fixed on the working surface, after which you can turn on the equipment.
Important! For laser operation, a cooling system is provided in the design, in which there is a liquid. Remember to check her level from time to time.
- In the process of work, you need to periodically monitor the process, although in case of failures the equipment will turn off on its own, so there is practically no danger of accidents.
Laser carving allows you to cut a product of the desired shape and apply a specific structure to the surface
The advantages of this group of equipment
If you are thinking about which version of the machine to choose, then this section will allow you to get acquainted with both the pros and cons of laser equipment. Let’s start with the merits:
|Accuracy||Laser cutting on wood is a high-precision process, because the thickness of the cut is 0.1-0.2 millimeters. If you need to process small parts and make structures of complex shapes, then this option is perfect for any of the purposes as well as possible, because the cutter is able to cope with the most complex contours.|
|High performance||The cutting speed is very fast, allowing you to do a lot of work in a short time. This allows you to save energy resources, in addition, you do not need your intervention during work, you just monitor the process and control it|
|Profitability||This applies both to energy consumption indicators (powerful motors in other types of equipment use much more electricity in operation) and to material consumption. High precision allows you to work with a minimum amount of waste and save material|
|Multifunctionality||The wood laser cutting machine can not only cut out elements of any size and shape, but is also perfect for engraving surfaces and creating relief paintings. Many companies make a lot of money just from this type of service, such as engraving on wood products.|
Important! When choosing a specific model, it is important to decide what materials you will process, because there are installations for wood, plywood, metal, plastic, and there are also universal options that can cope with different types of raw materials.
The equipment can take up quite a lot of space, especially if the desktop has impressive dimensions, so you should have a room for installing the machine
In addition to all the advantages described above, there are some limitations that you should be aware of:
- The ends of the elements are very flat, but they will be dark due to exposure to very high temperatures, this is a feature of this type of equipment that is worth remembering.
Woodworking with Thin Plywood, like Baltic Birch Plywoods
Cut ends are always dark due to high temperatures
- Laser cutting of wood is only possible if the material thickness does not exceed 20 mm. And in some cases, this figure is even less, therefore, using this option for processing thick workpieces will not work.
Features of the choice and use of installations
If you firmly decided that you need a laser cutting machine for wood, then you should be very careful about choosing a specific modification, we will tell you what criteria you should pay close attention to.
If you study the information on the network, but you will find many articles on how to make a laser cutter for wood with your own hands from an old CD drive.
In fact, you can assemble a powerful laser pointer that will not be able to cut material due to low power, and if you purchase the appropriate components with high performance, then the cost of the installation will be almost more than the finished design, so it is better to immediately choose a factory solution.
Handicraft options are too light to cut even thin wood
It is safe to say that this technology is the future, therefore, if you have a need for wood cutting, we advise you to pay attention to laser machines. The video in this article will help you understand some of the complex nuances in more detail.
DIY laser cutter for cutting plywood, wood, metal: assembly tips
The possibility of making something useful from unused or worn-out equipment attracts many home craftsmen. One such useful device is a laser cutter. Having such a device at their disposal (some even make it from an ordinary laser pointer), you can decorate products from various materials.
A homemade laser cutter can cut thin wood pieces or engrave glass
Manufacturing process of the simplest laser cutter
The main working element of the homemade cutter of the proposed design is the laser element of the writing computer disk drive. You should choose the writing model of the drive because the laser in such devices has a higher power, which allows you to burn tracks on the surface of the disk installed in them. The design of the read-type disk drive also contains a laser emitter, but its power, used only for illuminating the disk, is low.
Removing the laser module from the drive requires care
The laser emitter, which is equipped with a recording drive, is placed on a special carriage that can move in two directions. To remove the emitter from the carriage, it is necessary to free it from a large number of fasteners and detachable devices. They should be removed very carefully so as not to damage the laser element. In addition to the usual tools, to remove the red laser diode (and to equip a homemade laser cutter you need it), you will need a soldering iron to gently free the diode from the available soldered connections. When removing the emitter from the seat, you should be careful and careful not to subject it to strong mechanical stress, which may cause its failure.
The torch needs a red LED
The emitter removed from the computer’s recording drive must be installed instead of the LED that was originally supplied with the laser pointer. To perform this procedure, the laser pointer must be disassembled by dividing its body into two parts. In the upper of them is the LED, which should be removed and replaced with a laser emitter from a computer writing drive. When fixing such an emitter in the body of the pointer, you can use glue (it is only important to make sure that the eye of the emitter is located strictly in the center of the hole intended for the exit of the beam).
To control the power, you need to assemble the simplest electrical circuit, otherwise the LED may fail
The voltage generated by the power supplies in the laser pointer is not enough to ensure the efficiency of using the laser cutter, so it is impractical to use them to equip such a device. For the simplest laser cutter, rechargeable batteries used in a regular flashlight will do. Thus, by combining the lower part of the flashlight, which houses its rechargeable batteries, with the upper part of the laser pointer, where the emitter from the writing computer drive is already located, you can get a fully functional laser cutter. When performing this alignment, it is very important to observe the polarity of the rechargeable batteries, which will power the emitter.
Laser pointer cutter diagram
Before assembling a homemade hand-held laser cutter of the proposed design, it is necessary to remove the glass installed in it from the tip of the pointer, which will prevent the passage of the laser beam. In addition, it is necessary to check again the correctness of the connection of the emitter with the batteries, as well as how accurately its peephole is located in relation to the outlet of the pointer tip. After all structural elements are securely connected to each other, you can start using the cutter.
In principle, any suitable body can be used for a homemade cutter of this design.
Of course, with the help of such a low-power laser it will not be possible to cut a metal sheet, it will not be suitable for woodworking, but for solving simple tasks related to cutting cardboard or thin polymer sheets, it is suitable.
Cutter test. Electrical tape is cut like a knife through butter
According to the algorithm described above, it is possible to manufacture a more powerful laser cutter, slightly improving the proposed design. In particular, such a device must be additionally equipped with such elements as:
- capacitors with a capacity of 100 pF and 100 mF;
- resistors with parameters 2–5 Ohm;
- collimator. a device that is used to collect light rays passing through it into a narrow beam;
- LED flashlight with steel body.
Capacitors and resistors in the design of such a laser cutter are necessary in order to create a driver through which electrical power will flow from the batteries to the laser emitter. If you do not use the driver and send current to the emitter directly, the latter can immediately fail. Despite the higher power, such a laser machine for cutting plywood, thick plastic and even more so metal will also not work.
What materials and mechanisms will be required
To make a simple DIY laser cutter, you will need the following materials and technical devices:
- laser pointer;
- an ordinary flashlight equipped with rechargeable batteries;
- an old burner drive (CD / DVD-RW) equipped with a laser drive (it is absolutely not necessary that such a drive be in working order);
- soldering iron;
- set of locksmith tools.
The higher the write speed of the drive, the more powerful the laser cutter will be.
In this way, a simple laser cutting device can be made using materials that are easy to find in a home workshop or garage.
How to make a more powerful apparatus
Home craftsmen are often interested in more powerful laser machines that can be made by hand. It is quite possible to make a laser for cutting plywood with your own hands and even a laser cutter for metal, but for this you need to acquire the appropriate components. In this case, it is better to immediately make your own laser machine, which will have decent functionality and work in automatic mode, controlled by an external computer.
Depending on whether you are interested in laser cutting metal with your own hands or you need an apparatus for working on wood and other materials, you should correctly select the main element of such equipment. a laser emitter, the power of which may be different. Naturally, do-it-yourself laser cutting of plywood is performed with a lower power device, and a laser for cutting metal must be equipped with an emitter with a power of at least 60 W.
For a serious machine, it is better to spend money to purchase a laser diode of the required power
To make a full-fledged laser machine, including for cutting metal with your own hands, you will need the following consumables and components:
- a controller that will be responsible for communication between an external computer and electronic components of the device itself, thereby providing control of its operation;
- electronic board equipped with an information display;
- laser (its power is selected depending on the materials for which the manufactured cutter will be used);
- stepper motors, which will be responsible for moving the device desktop in two directions (such motors can be stepper motors from unused printers or DVD players);
- cooling device for the emitter;
- DC-DC regulator, which will control the amount of voltage supplied to the electronic board of the emitter;
- transistors and electronic boards for controlling the stepper motors of the cutter;
- Limit switches;
- pulleys for installing timing belts and the belts themselves;
- body, the size of which allows you to place all the elements of the assembled structure in it;
- ball bearings of various diameters;
- bolts, nuts, screws, ties and clamps;
- wooden boards from which the working frame of the cutter will be made;
- metal rods with a diameter of 10 mm, which will be used as guiding elements;
- a computer and a USB cable with which it will connect to the cutter controller;
- set of locksmith tools.
Electronic filling components can be selected individually or purchased from a set of accessories for a CNC machine
If you plan to use a laser machine for DIY metalwork, then its structure must be reinforced to withstand the weight of the metal sheet being processed.
The presence of a computer and a controller in the design of such a device allows it to be used not only as a laser cutter, but also as an engraving machine. With the help of this equipment, the operation of which is controlled by a special computer program, it is possible to apply the most complex patterns and inscriptions to the surface of the workpiece with high precision and detail. The corresponding program can be found freely available on the Internet.
By its design, a laser machine that can be made by hand is a shuttle-type device. Its movable and guiding elements are responsible for moving the working head along the X and Y axes. The Z axis is the depth to which the workpiece is cut. For the movement of the working head of the laser cutter of the presented design, as mentioned above, stepping motors are responsible, which are fixed on the fixed parts of the device frame and are connected to the moving elements using toothed belts.
Movable carriage homemade cutting
A very important stage in the manufacture of a laser machine with your own hands is its adjustment after the final assembly. Both the elements of the kinematic diagram of the cutter and its laser head are adjusted and adjusted. If the first problems usually do not arise, then alignment of the laser head is a rather complicated process, the rules for the implementation of which should be well studied.
we bring to your attention a couple of videos about assembling another version of a laser machine from two DVD drives.
Home Laser Engraving Machine Options
Despite their modest dimensions, desktop models of laser cutting and engraving machines are not inferior in accuracy and quality of work to their larger counterparts. Differences are observed only in the power of the emitter and, accordingly, the possibilities in terms of processing speed and the thickness of the materials. Below we will consider three running models with a short list of the main characteristics.
Small-sized laser engraving machine with a processing area of 220 × 200 mm. Like all the equipment discussed in the article, it is intended for non-metallic surfaces, for example, fabrics, paper, cardboard, plexiglass, plywood and the like. In addition to its small size and relatively low weight (40 kg), the model has the advantage of an automatic lifting function of the desktop within 20 mm. It is very convenient, first of all, for engraving bulky workpieces.
The device is equipped with a table illumination and a 40 W laser tube, the power of which is sufficient for through cutting of plexiglass up to 5 mm thick and plywood 3-4 mm. The speed of movement of the beam during engraving and cutting is not very high and amounts to 100 mm / s. Due to the fact that the machine has only the LPT port of the connectors, it can only be connected to a stationary computer. But the almost identical Rabbit HX-40B model is equipped with a USB connector, which allows you to connect it to a laptop and use external drives.
A small desktop engraver that can both apply images to the surface of non-metals and cut materials up to 4-5 mm thick (for plywood). The working area of the table is 200 × 300 mm, and the maximum power of the emitter reaches 40 W. The model is equipped with an air supply to the cutting area and a ventilation system. The included honeycomb table is convenient for working with small elements and greatly facilitates their cutting and engraving. To avoid retinal burns, tinted glass is built into the device cover, which does not obstruct the view. The machine is connected via USB, which opens up ample opportunities for connecting with external sources of information.
Unlike the two above-mentioned devices, the dimensions of the table for this model are 420 × 300 mm, therefore the machine itself is somewhat larger (1100 × 700 mm). This machine is also equipped with the function of raising / lowering the working surface, and the range of movement is 80 mm. The control button for this process is placed on the front panel of the case, there are also other functional switches.
Equipped with a tube with a maximum power of 40 W, it gives a stable beam, with which you can not only cut and engrave non-metals, but also apply images to metal surfaces, provided that they are coated with thermal paste. In this case, the engraving speed can reach up to 120 mm / s, and for the convenience of positioning the beam, the head is equipped with a laser pointer.
Laser machine at home. is it possible?
The concept of “machine tool” is usually associated with large factories that work in three shifts and continuously produce elements of furniture, cars and other massive and mass workpieces. As a last resort, the imagination draws a car or carpentry workshop.
In fact, among the variety of models of carbon dioxide lasers, there are completely miniature options that are slightly larger than an ordinary office printer and take up literally half of an ordinary desk. Such devices can be easily connected at home, which is what many lovers of tinkering during evening leisure do, or those who have chosen various handmade directions as a hobby.

What can be done on a home laser machine?
Compact and miniature laser cutting machines for home use cannot boast of a large working area and high speeds, but this does not make them completely useless. There are a lot of areas of application and things that are more expedient to be manufactured on equipment with precisely such performance characteristics:
- felt crafts. applications, holiday decorations (hearts for Valentine’s Day, New Year’s decorations, etc.), toys for mobiles over cribs, coasters for hot dishes and many other charming things are cut out of this dense material with a laser. The laser beam accurately and in detail cuts out the smallest curls or sharp corners, so even complex-contoured products are of high quality;
- paper and cardboard crafts. this includes cards, invitations to weddings and other celebrations, business cards, New Year’s and themed decorations, stencils for further interior decor and a very large list. The power of the laser emitter in desktop devices is small, so even the thinnest tissue paper after laser cutting looks aesthetically pleasing, without charred edges;
- products made of fabric, leather and leatherette. these can be both appliques and independent products or perforated decor (the laser burns holes in the material from which the pattern is formed).
- seals, stamps, cliches. the positioning accuracy of the laser beam, even when it comes to desktop devices, is about 0.01 mm, so it reproduces all images with perfect detail. This allows you to use the machine for the manufacture of any seals, except for GOST;
- working with plywood is such an extensive segment of products that it will be difficult to list everything. Here are just some of the options: prefabricated constructors, puzzles, decoration stands, plaques, cutting boards, various figures and much more;
- acrylic crafts. transparent, like a tear, material, perfect for various interior compositions, figurines that look especially impressive with lighting, boxes for storing jewelry, stands for cosmetics, etc.
- engraving. if before that it was mainly about laser cutting of materials, then this point implies the use of a laser tube at half the power, so that the surface is not cut through, but is covered with a pattern. Engraving can be applied to mirrors, glassware, stationery, wood and leather products.
Cut thin plywood without saw and chippings
Laser engraving perfectly conveys the contour and depth of images and is considered the most durable
Working on a laser machine at home
Technologies for processing materials using narrow-beam laser radiation were investigated relatively recently, 20-30 years ago, so laser machines can be called quite young equipment. However, this did not prevent him from rapidly occupying all production and service areas.
Before hitting the surface of the material, the laser beam passes through a system of mirrors and a special lens that focuses it into a tiny point.
A feature of the laser beam is a very high precision of work, which is several orders of magnitude superior to the results of any other tool. In combination with the equally high speed of passage, stability and relatively low energy consumption, the popularity and demand for such machines becomes clear. It should be clarified that we are talking about carbon dioxide laser devices, which are budgetary, easy to use and occupy today the main segment of the laser equipment market.
Features of home use of laser equipment
When placing a laser engraving machine at home, you need to remember that for high-quality work, it must be installed strictly in a horizontal plane. In apartments, however, absolute compliance with this requirement is not always observed, therefore, before installation, the future work surface should be measured with a level and, if necessary, level it to the desired values.
It should also be borne in mind that even with small dimensions, the laser machine remains serious equipment that requires compliance with safety measures during use and can be harmful to health, therefore, the rules for working with it must be taken seriously:
- use a hood;
- open a window or window for ventilation during and after work;
- if you have a tendency to allergies, wear a respirator or other bandage that prevents the penetration of vapors into the lungs;
- do not observe the cutting process when the lid of the machine is open;
- do not expose your fingers to the beam;
- keep young children away from equipment that is running or switched off;
- remember that cutting PVC on a laser machine is strictly prohibited (this prohibition is especially strict regarding the use of a laser at home). The polyvinyl chloride contained in the material is very toxic during high-temperature processing: the chlorine and dioxin vapors released during this process affect genetics, the immune system and can cause suffocation.
Cutting porcelain stoneware: 8 kinds of material
The better to cut porcelain stoneware
Sizes of ceramic granite tiles (cm):
The last size of the porcelain stoneware tile belongs to the so-called thin porcelain stoneware, which is most often used in the renovation of residential premises. It is especially beautiful when decorating walls and plinths of facades of private houses. There is another way how to cut porcelain stoneware tiles, but with small amounts of work, this is working with a glass cutter.
Complex shaped cutting of porcelain stoneware
Very often it is necessary to cut curly cuts in porcelain stoneware tiles. For example, for curved steps, holes in tiles for columns or pipes. How to do it?
What way to choose to cut the porcelain stoneware tiles figuratively:
- Hole saw;
What is the advice of a specialist in these cases? Hole saw. perfectly copes with the task when it is necessary to make round holes in porcelain stoneware. But alas, it works slowly but neatly. The ballerina also copes with the task of sawing round holes in the tiles, but she does it very carelessly, the edges remain uneven and often have to be refined by hand, and trimming is inevitable. The grinder is the best option for curved cuts.
When cutting tiles, the cutter should go a little further than the cutting line by 2-3 mm towards the chips.
Thus, it is possible to correct the unevenness of the cut with a grinder. It is necessary to work with a grinder “from oneself”. All tile ends must be sanded with a grinder or sandpaper. Next comes the final processing of the tile cuts. it is necessary to finish with a grinder, using flexible grinding wheels with a grain size of 0-100.
Simple cutting of porcelain stoneware with a tile cutter
It is necessary to find out what kind of tile cutters are. The types of tile cutters are manual and electric (this is a stationary machine). Basically, the principle of operation of an electric and manual tile cutter is almost the same. But they differ in price.
An electric tile cutter has more convenience and quality in cutting tiles, compared to a manual tile cutter, but an electric tile cutter has a rather high price, no one leases it, and it has a high energy consumption. But the quality is of course excellent. When working, there is practically no dust from the tile, since when cutting, water is supplied to the wheel and cools it.
How and how to cut porcelain stoneware floor tiles
It is best to cut your porcelain stoneware floor tiles using a grinder with a diamond wheel. But at the same time it is necessary to use personal protective equipment against dust and noise.
Personal protective equipment when working with a grinder:
- Protective gloves;
Experts give some advice for beginners when working with a grinder, if you need to cut porcelain stoneware floor tiles, because these tiles are thick. Place foam plastic under the tiles on a firm, flat surface. To reduce the number of chips, in the place of the cut on the tile on the front side, it is necessary to stick masking tape and apply a cut thread with a pencil on top of the tape.
Tiles need to be cut only on the front side.
With a large thickness of the tile, to control the accuracy of the cut, it is necessary to use a metal building corner, it is attached with clamps to the tile, on the front side, and thus it is possible to correctly cut the tile.
How to properly cut porcelain stoneware tiles at home
Porcelain stoneware is an excellent finishing material that combines the best qualities of ceramics and natural stone. The material is stronger than granite, wear-resistant and resistant to aggressive environments. The tiles are produced by the industry, various.
Types of porcelain stoneware:
- Technical porcelain stoneware;
- Structured or patterned porcelain stoneware;
- Slim. Slim.
You can cut any shapes and configurations from porcelain stoneware tiles at home. Porcelain stoneware tiles are often used in the design of the floor, steps of stairs, porches, walls and plinths of the house. Although the material is very hard, it often leaves unclean chips in place of the cut. Types of cutting porcelain stoneware tiles at home. using a grinder with a diamond disc (diamond), tile cutter, glass cutter, jigsaw, waterjet cutting (only industrial cutting on professional equipment).
A grinder with a diamond wheel is often the only option to cut porcelain stoneware tiles. But when working with this well-known tool, there are some nuances. The fact is that when tiles are cut, this work is associated with the release of a huge amount of harmful dust, an unpleasant burning smell and wild noise. Therefore, when working with a grinder, you must protect your eyes with goggles, and also wear a respirator.
When cutting tiles, you need to know that the diamond wheel must be kept straight without moving and clearly follow the line that is drawn on the back of the tile.
It is necessary to work with the disc carefully, lead the disc along the line, stepping back from the cutting line by 2-3 mm from the line towards the chips. And also it is necessary to press on the tool strongly and it is necessary to lead it along the line calmly, with great pressure. If you make a cut in this way, then the cut will be neat, without chips. There is also one more piece of advice when working with porcelain stoneware. The ceramic granite tile must be rigidly fixed, clamped with clamps and screwed to a fixed surface, for example, to a table. The fact is that this must be done according to safety precautions. after all, when cutting, you must press hard on the tool.
Granite processing at home
It is clear that cutting porcelain stoneware tiles is quite difficult. And more often than not, beginners should seek professional advice. They have special tools and experience.
This technology has a number of advantages that can be safely called “with a guarantee”.
- Sawing is very fast;
- There is no charring and other unpleasant consequences of thermal effects on the material;
- The cut is no less accurate than with laser processing and there are no complaints about the edges;
- Due to the high accuracy, plywood cuts make up no more than 6 percent of the total amount of material.
But this is a common cut that can be done even at home. Not the last place in considering the issue of material cutting on CNC equipment is figured cutting. Curly cuts are also possible here and the result will be decent.
We do crafts ourselves
Once upon a time, plywood cutting was very popular, craftsmen widely advertised their creations, especially since this hobby was, perhaps, one of the cheapest. Judge for yourself, the tool for cutting plywood is a jigsaw.
Really something, but a jigsaw could always be found, although files were periodically in short supply, problems were solved with them. And that’s it, nothing else was needed. It was later that special tables and fixtures appeared. Jigsaw
But, by the way, the principles of working with this tool remained unshakable, here they are:
- Jigsaw files are very fragile, so they move only in one, strictly vertical plane. Any distortions can lead to the fact that the canvas will simply burst. The saw directly works when moving down, the saws are also located, teeth down;
- The workpiece is movable, the nail file is relatively static. This suggests that when working with workpieces in difficult areas, it is the workpiece that scrolls, and the canvas remains in one place, while the movements become more accurate;
- In various sources, there are references to the fact that the work begins in the inner contour, and after that it moves to the outer perimeter. In this regard, our recommendation;
If the outer perimeter does not have complex patterns that can be damaged when working according to internal schemes, then you can start work from the outer perimeter, thereby lightening the weight of the workpiece itself.
Observing these simple rules, you can create interesting carved grates, cutting boards, and you never know what with your own hands. Jigsaw sawing is still an interesting and promising hobby.
Plywood cutting. Ways. Curly cutting, crafts and use of the cutter
As with any building material, plywood is cut to fit the required dimensions. Plywood cutting can be done either manually or using special equipment. And here the main thing is to observe the accuracy of the cut (the absence of curved lines is the key to success).
And do not forget that working with plywood involves not only using it for construction needs, quite often plywood products are used as decorative elements. Openwork lattices, boxes, stands and other homemade products look very cool, especially if they are made by a master.

Cutting methods for general use
When working with material, you cannot go anywhere from fitting to size, so you still have to make cuts of plywood. At the household level, these operations are performed either with a knife, or with a jigsaw, or with a circular saw.
It is worth recalling the basic rules for working with this material, especially since cutting plywood to size is far from the last in the cycle of construction work.
- Thin plywood is cut with an assembly knife, easy and simple (thin plywood is up to 2 mm);
- Cutting plywood up to 6 mm is done with a jigsaw; (see also Sawing with a jigsaw from plywood: drawings and rules for working with the tool)
- Puff over 6 mm requires a circular saw.
You can just saw it.
For your information!
Please note that:
- Firstly, softwoods used in the production of plywood have a more viscous structure due to resins of natural origin, which blunt the cutting edge of the tool very well;
- Secondly, working with plywood involves working along the grain. If it becomes necessary to cut across the fibers of the outer layer, then weakening cuts are first made in it with a knife, and then with the main cutting tool;
- Thirdly, plywood does not tolerate rough mechanical penetration, therefore, before driving a nail or screwing in a self-tapping screw, a hole of the required diameter must be drilled in the plywood.
As for the usual straight-line processing of plywood, it’s time to remember about curly cuts.
Shape cutting. various options
Not on a single fit, work with plywood ends. In this case, not the last place is taken by curly cutting or sawing.
Currently, there are several basic techniques that will allow you to turn a piece of dead material into almost a work of art.
- Figured cutting of plywood with your own hands. This is an ordinary jigsaw and a set of files for it;
- Figured cutting of plywood on CNC. milling cutting;
- Shape cutting. plywood is processed using a laser.
We will consider these options in more detail.
From everyday creativity to industrial production
Laser cutting of plywood sheets, this section is dedicated to it. Any instruction on the use of laser technology will tell you that the basic principle that is used in this case is beam burning.
At the same time, the technique, of course, has a number of indisputable advantages that are so in demand today.
- Cutting quality is maximum, minimum thickness is very difficult to achieve with any other equipment;
- Efficiency of processing, there is no need to work with burrs, chips and other defects that may arise during mechanical processing;
- Precision and versatility. The details that come out of the laser processing have exactly the same dimensions, and the patterns that this beam draws can be of any complexity.
The story would be incomplete if we did not discuss the possible risk when working on such equipment and, if you want, about the negative aspects when using these machines.
- A laser is a laser, and an overpowered beam can cause carbonization of the material and even fire. The technology provides for a special air supply to avoid such consequences, but the risk remains. In this case, one has to rely on the experience of the operator;
- Each type of wood and type of glue requires its own processing mode, the final result also depends on the ability of the worker to determine the type of product by its appearance;
- And again the human factor. If the machine operator is inexperienced, and the beam hits a knot, then there is a high probability of falling out of this knot, and, therefore, a defect in work.
Here are some interesting things that can happen.
As you can see, all risks are associated with the experience and skill of the employee. Although the equipment is programmed for drawing of any complexity, lack of experience can lead to sad consequences.
Cutting plywood is a more complicated process than cutting wood. This is primarily due to the multidirectional fibers and viscous adhesive compositions. However, modern equipment will calmly cope with this problem. The video in this article is ready to demonstrate various aspects of this topic, look.
Figured cutting of plywood: methods, process nuances and prices
Curly cutting of plywood (cutting out figures from a sheet of plywood using a machine) is popular among decorators and furniture makers. Using a sheet of plywood and special equipment, you can create not just a home decorating craft, but a whole work of art.
Laser cut decorations for home decoration
Sawing methods (basic techniques)
You can cut out a figurine using:
- plywood shape cutting machine. laser equipment;
- an ordinary jigsaw (you will also need a set of files for it);
- CNC. milling equipment.
Before you start cutting, using one technology or another, you should know some of the nuances that must be taken into account when working with glued veneer:
- Be aware that plywood made from pine / spruce will be much more difficult to carve than other types of wood. This is due to the fact that coniferous varieties have a viscous structure due to resins.
- It is necessary to cut the glued veneer in the direction of the grain. If you need to make a cross-cut, then in this case, first make small cuts with a knife, and then proceed to sawing with the main tool.
- Before hammering in a nail, you need to make holes for it.
Sawing with a jigsaw
- It is necessary to saw only in one vertical plane. Saw movements must be carried out “up and down”.
- If you need to make a turn according to the drawing, then turn the workpiece, and not the base.
- Sawing begins in the inner contour. Then go to the outer contour.
- Cool the file periodically (suspend work for 10-15 minutes). Otherwise, it will become unusable.
Note. From ancient times to the present, sawing with a jigsaw is considered an interesting and creative activity.
Creating a masterpiece with a hand jigsaw
Plywood sheet laser cutting
Principle of operation: burning with a beam along the contour. The main advantages of this technique include:
- it is not necessary to process / file the edges of the figure after cutting;
- high-quality cut;
- the size of all laser-processed parts is the same;
- you can burn out a pattern of any complexity.
The disadvantages and possible risks when working with laser equipment include:
- with excess power, plywood can be charred (despite the fact that the technology provides for a special air supply, there is a risk of fire / charring, albeit small);
- When looking at plywood, a master should be able to determine what species the veneer is made of and what kind of glue it is glued with (the burning mode depends on the type of wood and the type of glue);
- if a beginner works with such equipment, and in the process of burning out, the beam “randomly” (due to the inexperience of the operator) hits a knot, then the product will deteriorate.
Before you start cutting plywood with a laser, you need to learn how to work with this type of equipment. How the figure will look depends on experience.
Cutting with a milling machine
The main advantages of this cutting method include:
- fast sawing;
- during the process of cutting a figure from plywood, charring and other unpleasant consequences will not occur (this technique is best suited for beginners);
- cutting accuracy is the same as when using laser equipment;
- no need to process (grind) the edges.
The milling machine is also good at art
