which is better to choose and which one is needed
A lot depends on the correct choice of starting material. Therefore, it is so important to understand before starting work what points you need to pay special attention to when buying plywood for laser cutting. This will help keep the number of marriages to a minimum.
What is plywood?
This is a multi-layered material, for the manufacture of which thin sheets of veneer and adhesive are used. Wood sheets, placed in each layer perpendicular to the previous one, are covered with glue and pressed together, forming a single strong wood layer.
Special placement of veneers relative to each other gives strength and density to the material.
And the type of glue depends on its moisture resistance and scope.
For example, FK plywood, which uses a carbamide resin adhesive, has a low level of moisture resistance, but at the same time reduced toxicity, which is ideal for indoor use. While the PSF brand based on phenol-formaldehyde glue boasts excellent moisture resistance, but toxicity is also at a high level. In this regard, this material is recommended for outdoor use.
Which plywood can be used for laser cutting?
It is possible to cut with a laser any piece of wood and plywood as well. But what the result will be is another question. Indeed, the quality of the cut, the amount of marriage and how presentable the final product will look depends on what kind of material is used.
Glue for gluing sheets
Various adhesive materials are used to connect thin wood sheets to each other: resins, glues. Moisture resistance and environmental safety of plywood depends on what kind of material is used in production.
There are two main groups:
- Animal origin (casein, albumin and albumin-casein). With a clear conscience, they can be called environmentally friendly, since the raw material for glue is protein from milk or animal blood.
- Synthetic origin (based on urea-formaldehyde, phenol-formaldehyde and other resins). It is worth remembering that all synthetic adhesives release chemicals into the air to one degree or another. The only question is the amount of these substances.
The best properties in terms of price, quality and environmental friendliness are possessed by FK grade sheets with glue based on urea-formaldehyde resin, when heated, a very small amount of substances harmful to humans is released into the environment.
IMPORTANT : Plywood (PSF) that uses phenol-formaldehyde glue is not recommended for use due to increased toxicity and low laser penetration.
Plywood grade
The grade of plywood is affected by the presence of defects: knots, cracks, wormholes, glue seepage, uneven edges and uneven sheet thickness.
In total, 5 varieties are distinguished, the differences of which are presented in the table.
| variety | partially fused, consumed knots, wormholes | Large prevailing knots | are allowed |
| 0044 | |||
| I | Up to 6 mm diameter, max. 3 pcs. per 1 m 2 | Diameter up to 15 mm, max. 5 pcs. per 1 m 2 | Minor brown veins |
| II | Up to 6 mm in diameter, not more than 6 pcs. per 1 m 2 | Diameter up to 25 mm, max. 10 pcs. per 1 m 2 | Repairing the sheet surface |
| III | Up to 6 mm in diameter, no more than 10 pcs. per 1 m
The type of plywood directly affects the laser cutting process (the amount of rejects) and the appearance of the finished product (charred edges when passing knots due to the need to increase the laser power; undercut due to the walking thickness of the material or the uneven surface of the sheet). That is why grades E, I and II are ideal for laser cutting. It is allowed in certain cases to use plywood marked 2/3. ThicknessFK grade plywood, which is most often used for laser cutting, can have a thickness of 3 to 21 mm. But from the point of view of the ratio of price and quality, it is optimal to stop at a material with a thickness of 3 to 6 mm. Processing thicker sheets will require an increase in time and energy costs, which will ultimately affect the cost of the product. Moreover, the increase in laser power required to cut a thick sheet results in an unsightly charred edge. Type of wood veneer The choice of wood used in the production of plywood depends on the purpose and effect to be achieved. There are three types of plywood according to the type of wood veneer (only the composition of the outer layers is taken into account):
Other criteriaIn addition to the above, it is necessary to pay attention to such criteria as:
Differences in plywood for laser and milling cutsMilling cutters are not as sensitive to defects in the raw material. And this means that plywood of all five grades from grade E to grade 4 can be processed on a milling machine without any problems. Moreover, the thickness in this case is not limited to 6 mm. The milling cutter can easily cope with a sheet up to 100 mm thick. What is the best plywood for laser cutting?The ideal option for laser cutting is FK grade plywood, grade at least 2/2, thickness from 3 to 6 mm. As for the type of wood veneer, it depends on the goals and the effect that needs to be obtained. With the right approach to the choice of material for laser cutting, you can achieve excellent results, both aesthetic and economic.
Get expert advice the best way to level the surfaceDespite the fact that many modern building materials are now appearing, plywood is still firmly occupying its niche. Many options for sheet sizes and thicknesses greatly simplifies installation. And the possibility of any finish adds more points in its favor. Contents
Puttying plywood for subsequent finishing
Plywood is a wood-based building material consisting of layers of veneer glued together. Is it possible to do this, features of the processIf it is planned to paint the walls and ceiling, and plywood sheets were used during construction, then the question arises quite reasonably whether it is possible to putty plywood. Experts believe that it is not only possible, but necessary. The main feature is that it is a wooden material and it is important to choose the right building mixes for the work. Putty for plywood is allowed only on certain grades of sheets (FSF, FSF-TV, FB, BBS, FK), since moisture resistance is a mandatory requirement for the material. Like other wood-based materials, plywood must be impregnated with a deep-penetrating primer with antiseptic properties. Particular attention is paid to the joints of the sheets. The filling process itself is no different from working with other surfaces. Finishing technology for wood fiber boardsBefore you start puttying plywood, all sheets must be thoroughly dedusted and treated with a moisture-resistant wood primer twice. Sheets can rarely fit absolutely exactly and if there are differences, then they need to be sanded before leveling. Then fill the gaps between the sheets with putty, cover up fasteners and other irregularities, if any. If the distance between the sheets is large, then a sickle is glued onto the first layer of the mixture. After re-puttying and drying the solution with sandpaper, grind the surface. When the surface is puttied and sanded, you can move on to painting or wallpapering, regardless of whether it is a wall or a ceiling. If the plywood lies on the floor and it is planned to cover it with linoleum, then the base is treated with drying oil or PVA.
After complete drying, the floor is treated with an antiseptic solution to prevent mold and mildew. At the last stage, the surface is covered with acrylic varnish. How to choose the right mixture, consumption per m2
The following compositions are most suitable as putty on plywood:
Types of plywood and methods of processing it for painting or wallpapering
Plywood differs in different degrees of water resistance.
Depending on the degree of processing, they distinguish:
If plywood with a sanded side (W1) was taken during construction, then it can be immediately primed and wallpapered. The primer is applied in two layers and waiting for complete drying.
For decorative painting, puttied plywood. For this, it is best to take unpolished plywood (NSh), since there will be good adhesion to the building mixture. If it is planned to finish with liquid wallpaper, it is also better to use untreated plywood, having previously primed it twice. How to properly putty, tools
In general, the technique for applying putty on plywood is no different from other substrates such as brick or concrete. Of the tools you will need:

And his price is high. 
Having familiarized yourself with the main criteria in advance, it is possible to avoid many problems with marriage and cut defects. 
The veneer can be coniferous, birch or hardwood, it is glued together in different directions to increase the bending strength of the final sheet. 
To do this, PVA is mixed with ground wood dust. The resulting solution can be brought to the desired viscosity. Of the obvious advantages - low price compared to store options. Approximate consumption - 0.5 kg per 1 m2;
