But how do you cut and engrave plywood with precision and quality? What kind of plywood should you use? What kind of machine do you need? In this comprehensive guide on laser cutting plywood, we will answer all these questions and more. We will also help you choose the best plywood and the right machine for plywood laser cutting with perfection.

Can You Laser Cut Plywood?

Yes. Plywood can be easily cut using a laser cutter, which is the reason it is mostly preferred for cutting as well as engraving. Furniture makers, artists, decorators, business owners, and professionals use laser cutters to cut plywood because it offers precision and fine results in minimal time.

What is Plywood?

Plywood is an engineered wood that consists of thin layers of wood veneer. These layers are glued together in alternating grain directions. The thickness of each layer can vary from 1.5 mm to 2.5 mm, depending on the requirement. The layers are stacked until the desired thickness is reached.

Thus, plywood is not harder than solid wood. Most of the time, solid wood is harder or sometimes equally hard. It means if a laser cutter cut solid wood of a particular type, it can also cut its plywood. 

How Plywood Laser Cutting Works?

Laser cutting is a technique that uses a high-energy laser beam to cut through materials with precision and speed. 

The process of laser cutting plywood involves focusing the laser beam on the surface of the plywood and moving it along the desired path, which is controlled by computer. The laser beam heats up and vaporizes the wood material along the cut line, cutting the plywood into desired shape. 

In addition, laser cutters can also engrave intricate designs and patterns on plywood with fine details.

What Laser Should You Use to Cut Plywood?

To laser cut plywood, you need a suitable type of laser. You can only use a diode laser or CO2 laser to cut and engrave wood and plywood. Fiber laser cutters are mainly designed for cutting metals, and they are not recommended for cutting plywood. Fiber lasers are too powerful and can cause the plywood to catch fire. Moreover, fiber lasers create poor marks on wood that are not readable or aesthetically pleasing.

How Thick of Plywood Can a Laser Cutter Cut?

The thickness of plywood that a laser cutter can cut depends on the type of laser and the power of the laser. Let's understand these variables.

As far as the type of laser is concerned, CO2 lasers are quite powerful. They can cut plywood easily. Therefore, CO2 lasers are preferred for this task. However, diode lasers are also excellent, and due to new technologies, they can do a better job than traditional diode lasers. The most important thing about diode lasers is that they have a longer life compared to CO2.

The power of the laser plays a very important role. The higher the power, the more easily it can cut wood or other materials.

By power, we mean the laser optical/output power. You might see various power ratings listed in the specification. The machine power represents the power consumed by the machine.

The laser module also has two powers; one is the laser optical/output power, and the other is the laser electrical power. You need to see the optical/output while selecting a laser engraving or cutting machine.

The DIY laser engraving and cutting machines available on the market can cut plywood up to 15mm in one pass. CO2 lasers of around 40W can cut 10-15mm basswood, and diode lasers can cut 3-10mm basswood in one pass, depending on the optical/output power. For example, the xTool D1 Pro (20w) can cut 10mm basswood in one pass.

If the laser machine cannot cut the plywood in one pass, it will take one or two more passes. But several passes mean the machine will take more time, which will reduce productivity.

More Tips for Plywood Laser Cutting and Engraving

Edge Burn 

The burning of edges when you laser cut plywood or wood is quite common. It does not look appealing at all. There are a few tactics to reduce the edge burn while cutting.

First, you can try some other settings on your laser machine. Try a lower power and higher speed.

For surface edge burns, you can try applying masking tape on the plywood before engraving and cutting. The burn marks will appear on the masking tape, and the wood will remain safe.

The main cause of these burns is the production of smoke. Therefore, an air assist and exhaust system in the laser machine can be very helpful.

You can remove the burned edges using sandpaper. You can also try soap and denatured alcohol to clean the burnt area.

Smell

The smell is because of the adhesive used in plywood. You cannot eliminate this smell, but if you use an air assist and exhaust system, then there won't be an issue of smell.

Some laser machines are enclosed, and they have an exhaust system, such as Laserbox Rotary. While in some machines, you can attach the exhaust system and use an enclosure.

Fire

The laser machine should be equipped with the safety feature or a fire safety set of detecting any flame or fire. Never leave it unattended when it is working. Plus, you should also arrange a fire extinguisher to deal with any problem.

The fire in plywood cutting is mostly caused by the debris and particles that result from cutting. There should be an air assist to blow the residue away.

Conclusion

Plywood can be cut using a CO2 or diode laser engraving and cutting machine. With the necessary precautions and tricks, you can get the best results.
