Laser Engraving on Wood – Everything you need to know

Laser engraving is a handy and practical technique used to create permanent marks on various materials including but not limited to textiles, acrylics, wood, natural stones, metals, etc. From engraving company logos on products to making personalized gifts, there’s plenty of things you can create with a laser machine.

Wood is particularly loved by most beginners due to its versatility and availability. Never mind the fact that it can be a bit challenging to working with.

So how do you laser engrave wood? Well, laser engraving on wood happens pretty much like in other materials – a laser beam is passed over the material which heats it up and vaporizes it. The result is a smooth, clean, and perfect engraving that cannot be imitated by other woodworking equipment.

The main difference between laser engraving wood and other materials is that in wood, it is typically a sublimation process. This means that as the laser beam is passed over the material, it is converted via combustion into a gaseous state. Expectedly, the process creates smoke in the processing area from time to time during laser engraving.

Because it is natural, wood has a ton of inconsistencies that can be problematic when engraving. Fortunately, once you get the hang of things and discover the right power settings and speed for different wood types, you will end up with perfect engravings. Wood is quite adaptable. Not only is it easy to cut and engrave but it comes in lots of different varieties, shapes, and sizes.

How Laser Engraving Works on Wood

Laser engraving uses a focused laser beam to remove material from the surface of the wood. The heat from the laser burns the wood, creating a design with depth, contrast, and precision. The depth of the engraving can be controlled by adjusting the laser’s power and speed settings.

How to choose the best wood for laser engraving

The type of wood you plan on cutting into is of the utmost importance when laser engraving on wood. For instance, a bamboo cutting board will not engrave the same way an oak barrel will. Ideally, softwoods such as redwood, western red cedar, southern pine, and balsa don’t need high laser power to engrave.

They also cut quicker and result in lighter engravings. On the flip side, hardwoods such as dense wood, Brazilian ebony, snakewood, and African pearwood require more laser power to cut through and engrave. These also give off dark engravings. Ultimately, the type of wood used will affect the final output.

Most CO2 lasers can handle all types of wood but there are plenty of other engravers that are best suited for certain wood types. For instance, if you own an industrial laser engraver with the capability of engraving on harder materials such as stone and metals, laser engraving on wood will be a walkover.

Choosing the Right Wood for Laser Engraving

Not all wood types are equally suited for laser engraving. Here are some common options:

• Softwoods (e.g., pine, cedar): Burn easily, producing darker engravings, but may lack uniformity.
• Hardwoods (e.g., oak, maple): Provide finer details and consistent results but may require higher laser power.
• Plywood: Offers affordability and a smooth surface but may produce uneven results due to glue layers.
• Exotic Woods: Known for unique grain patterns and colors, though they can be more challenging to engrave.

Tip: Use untreated wood to avoid toxic fumes from coatings or chemicals.

Should the wood be sappy or dry?

Apart from the type of wood to use, the resin content is also very important when selecting the best wood for laser engraving.  Wood largely burns lighter or darker depending on its sap or resin content. For woods with low resin contents, the laser beam vaporizes the wood and leaves a minimal burn.

If the resin content is on the high side, the laser beam will consume the resin and dig deeper into the wood leading to a darker burn. In case you are wondering which wood types have a high resin content, cherry and alder top the list every time. Both are excellent for light-color engraving projects. However, cherry tends to have a high level of streaking but still makes for an excellent material for wood engraving projects.

Preparing Wood for Laser Engraving

1. Sanding: Ensure the wood surface is smooth and clean for better engraving results.
2. Masking: Apply masking tape to the surface to reduce scorch marks and make cleanup easier.
3. Testing: Run a test engraving on a scrap piece to adjust the laser settings.

Optimizing Laser Settings for Wood

Achieving the best results depends on fine-tuning your laser engraver. Key settings include:

• Power: Higher power for deeper engravings, lower power for surface-level designs.
• Speed: Slower speed allows for more precise engraving; faster speeds reduce burn depth.
• Focus: Ensure the laser is properly focused on the surface for sharp details.
• DPI (Dots Per Inch): A higher DPI creates detailed engravings but may take longer.

Design Considerations for Wood Engraving

• Contrast: Designs with bold, simple lines work best for wood engraving.
• Grain Alignment: Align your design to complement the wood’s natural grain for a professional look.
• Types of Designs: Text, logos, images, and patterns are all possible. Consider using grayscale for varied shading effects.

Finishing Touches

After engraving, you can enhance the final product with these steps:

• Cleaning: Remove any residue or soot using a soft brush or damp cloth.
• Sealing: Apply wood oil, varnish, or polyurethane to protect the engraving and enhance contrast.

Other important parameters worth considering when laser engraving on wood

As we have already established, the type of wood plus its resin content are important factors for any laser engraving on wood projects. But there are other equally important factors worth mentioning;  

• Engraving parameters: if you want a darker engraving on wood, you can increase the defocus of the laser beam. Doing this will not only decrease the density performance of the laser but it will increase the spot size of the laser as well. The result is that more wood will be burned as opposed to passing the beam directly in a gaseous form. Unfortunately, this fantastic strategy loses some engraving details in the process 
• Cutting parameters: you can determine the cutting quality of your laser by adjusting your cutting parameters accordingly. To achieve this, run a test of what to expect by drawing a rectangle with two rounded corners on a piece of paper. Send this to a laser. Begin with a cutting speed of 2-5% and a high performance for a 3mm-thick wood. Gradually reduce your cutting speed until you arrive at your desired quality.
• Material preparation: when you run a wood laser on a wooden material, you will notice a cloud of sticky dust forming on the engraved object. This is not only annoying but can easily cause your machine to malfunction. To counter it, glue an application tape over the working surface to act as a temporary protective layer. When you are done engraving, simply remove it and clean your object. Application tape is used for large surfaces but isn’t ideal for very small engravings and photo-engraving. This is because you will need to remove hundreds of small parts after the task is completed.
• Use the right optics: as mentioned before, wood engraving is basically a sublimation process. The choice of the correct optics coupled with precise focusing is paramount. The rule of thumb is to use a shorter focal length on the lens to attain finer details. A 1.5” to 2.0“lens will get the job done for most wood engraving tasks. However, when cutting through wood, the material thickness comes into play. Here, the thicker the wood, the longer the lens’s focal length used.
• Compressed air: Compressed air is not entirely used on all wood laser engraving projects. However, it is highly recommended when cutting wood. A small nozzle diameter helps protect the lens and direct compressed air on the cutting gap. This instantly removes gas and dust and enhances the cutting quality of the laser.
• Cleaning: it is easy to ignore the importance of cleaning the laser hardware and optics but it has a direct impact on the functionality of the laser machine. Wood dust is loaded with oils and resins which makes is really sticky. When it settles on the machine, it won’t be long before it malfunctions. It is, therefore, necessary to clean the laser engraver on a regular basis.
• Streaking: streaking may be lovely in zebras but it is not so in wood – especially wood for laser engraving. The reason is that it steals the attention away from the engraving rendering your efforts useless in the end. When laser engraving wood, always pick wood with minimal streaking and a smooth consistent grain. Woods with smooth and consistent grains have nominal alternating dark and light streaks. Any engraving done on such wood types looks detailed and clearer compared to the one with a high level of streaking.
• Color of wood: Since you cannot really manipulate the base color of wood, you are better off working with lighter wood. Essentially, the base color always follows the wood color. It is therefore important to consider the original color of the wood you intend to work on before embarking on the project.  Dark wood typically obscures your engravings making them quite hard to see or recognize. Lighter wood, on the other hand, develops an attractive dark burn when engraved that is great for optimal visibility.

Prepare Wood For Laser Cutting - Everything You Need To Know

Use Transfer Tape for Laser Engraving on Wood to prevent burn marks

Getting plywood or MDF laser cut without scorching it is a frequently asked question about laser engravers. Laser engravers can be used both for engraving and cutting. In the case of engraving, the beam’s power level is not high enough to burn the wood beyond what’s expected.

However, cutting something thin like plywood requires more power and generates more heat. The act of cutting the wood can scorch it and leave burn marks. It won’t bother everyone. But pickier customers might not appreciate an intricately laser cut wood piece with burn marks all over. Fortunately, there’s a simple solution to this problem.

A solution to a problem with a high-tech instrument like a laser engraver would seem to be a specially designed gadget or widget. This is not true. A simple layer of masking or transfer tape prevents the scorching of laser-cut plywood. You can apply transfer tape to plywood or MDF before cutting.

Is it because applying a thin layer of tape helps prevent burn marks on the wood? Does it reduce the laser beam’s temperature on the wood? No. Burn marks on the wood or MDF are not caused by the laser’s heat. Singeing results from the interaction of the air next to the wood in the laser beam.

This air is combusted right next to the plywood surface and causes the scorched appearance. This is prevented by the tape because it keeps the burning oxygen away from the wood surface. There will still be some darkening on the cut edge of the wood, but the surface will be unmarred and ready for your most discerning customers.
