Laser power of a laser cutter for wood
With a CO2 laser cutter you have a perfect machine for cutting wood. From laser powers of 60 Watt you can cut through (thinner) wood. With more laser power you can in principle cut through thicker wood, but it is important to look closely at how the end result will be. With thicker wood, the laser needs more time (even with more power) to reach the underside of the wood. As a result, soot or burns often occur at the edges.
Demonstration where your wood is cut
The extent to which soot formation is acceptable is usually an estimate that our customers make themselves. By performing some simple cutting tests on the customer's own wood, an estimate can be made quickly of what quality the customer needs for the specific application. Contact MetaQuip to see together which laser cutter for wood is the best choice for you. The exact achievable thickness depends on the type of wood. Compressed wood generally requires more laser power than natural wood. Here are some practical examples to get an impression of what is possible.
- You can effortlessly cut plywood up to 15mm with a 130W machine replica, but the edges will be dark.
- With a 100W machine 4mm birch or poplar can be cut tight and almost soot-free without further finishing.
- 4mm poplar can also be cut with a 40W machine, but then it has to be finished and sanded to get the soot.
- 12 mm poplar plywood can be cut with 85% power at 130W with approximately 25mm / sec.
These kinds of considerations are the points that a customer should consider when purchasing. Of course, based on extensive experience, MetaQuip can help you make the right choice.

MDF laser cutting
At MetaQuip we regularly get the question whether MDF can also be cut well with a laser cutter. It is important to realize that MDF is not really a wood, but compressed bonded wood fibers. The waste gases and substances that are released during the burning of this adhesive are harmful. We therefore recommend that you always take sufficient time to open the laser valve after the cutting task has ended. This ensures that all vapors are well extracted. The air discharge is also important when cutting MDF. Extraction must take place directly to the outside and / or use must be made of a industrial air filter. MDF can be cut with a laser to large thicknesses. Consequence is often that there is a lot of soot build up at the edges.
Work surface of a laser cutter for wood
The working surface of the laser cutter determines the size of the wood plate that you can process with the machine at one time. We normally use the rule that it is advisable to stay out of the edges until about 10%. MetaQuip has laser cutters for wood with different work surfaces: 40 x 40cm, 50 x 30, 60 x 40, 100 x 60 to 150 x 90cm. These are all machines that work with a valve, so that laser safety is guaranteed at all times. If you need a larger work surface (up to 150 x 300 cm) you can use an open bed CO2 laser, so-called portal lasers.
- Place the wood to be cut on a wooden base plate or blocks so that no light is reflected when the laser hits the knife bed or honeycomb bed at the bottom.
- Use good quality wood (especially with plywood) so that no local combustion occurs due to irregularities in the material (as often happens with the cheaper construction market variants).
- Minimize soot build-up around the cut line by covering the surface with masking tape to prevent combustion gases from settling on the wood. After removing any soot on the side, remove the masking tape and you will have a smooth, naturally colored surface (this also works perfectly when engraving wood)
