Laser cutters can cut wood with a thickness of up to 30 mm. However, most laser cutters are more effective when the material thickness ranges from 0.5 mm to 12 mm. Additionally, the thickness of wood that can be cut with a laser cutter largely depends on the wattage of the laser machine.
It has a maximum cut depth, so you have to choose your wood type and cutter properly. In this post, I will discuss how laser cutters work, their maximum cutting capacity, and tips you can use on your next projects.
There’s also a limit to how thick a laser can cut plywood. Most lasers can cut 12-20mm plywood, but it will take longer and require a larger number of passes. The finish also varies in quality on thicker plywood sheets.
The best setting for laser cutting wood typically involves using a moderate power setting with a moderate cutting speed to achieve clean cuts without excessive charring. Adjustments may be required based on the wood type, thickness, and desired cutting depth.
What wood can you laser-cut? You can easily laser-cut most wood with low grain density and thickness. Alder, balsa, basswood, birch laser plywood, poplar, cedar, and pinewood are some of the best options for laser cutting.
You can refer to different laser cutting thicknesses and speed charts to conclude what laser power you need, as they will give a clear-cut idea of material thickness, speed, and air-assist requirements for different laser powers.
Instead, the best way to cut thick pieces of wood with a laser cutter is by cutting halfway through on one side, then flipping the material and cutting the same pattern on the other side of the wood. Alignment circles help ensure that the pattern is placed correctly.
The WeCreat Vision's laser power is 20W, it cuts through various kinds of plywood and acrylic easily within 1 pass or several passes. Please refer to the following picture about the maximum thickness of materials the machine can cut.
The maximum thickness a laser cutter can cut through wood primarily depends on the laser power and the type of wood being used. Generally, a laser cutter with a power range of 40-150 watts can effectively cut through wood up to ¼ inch (6mm) in thickness.
The maximum thickness depends on the wood, but diode lasers can typically cut up to about ¼” thick wood. CO2 and fiber lasers can cut thicker wood depending on their power. A 90W CO2 laser can cut wood up to 20mm wood (about ¾” thick).
