Wood Laser Engraving and Cutting: A Practical Guide

Why Wood?

Wood laser engraving and cutting open up more possibilities for processing wood materials. Wood is one of the most common materials used in laser applications. Due to its durability and natural grain patterns, wood finds extensive use in sectors such as construction, furniture, interior design, and craftsmanship. Possessing both practicality and aesthetic value, wood customization offer even greater versatility.

There are various types of wood materials. Among them, plywood, solid wood, and MDF, are frequently employed in laser processing. In comparison to traditional woodworking methods, wood laser engraving and cutting offer greater convenience and efficiency, replacing the need for complex tools like saws, planers, and drills.

Common Types of Wood for laser processing

High strength and hardness are advantages in wood applications, but they present challenges in traditional carving and cutting processes. However, laser can effectively handle various hardness levels. With sufficient energy, it can effortlessly cut through even the hardest materials.

What are the popular wood products processed by laser?

Decorative Items

On one hand, wood laser engraving adds depth, texture, and intricate details, turning simple wooden objects into captivating decor. On the other hand, different wood species react uniquely to laser etching and burning, creating striking visual depth and contrast. Artisans personalize wooden decor items like wood carvings, wall hangings, and picture frames with customized names, logos, and design elements.

Furniture Components

Wood laser engraving and cutting allow for customized, elegant details and enhances the aesthetic appeal of furniture pieces. It not only allows creativity in design, but also saves a lot of time compared to hand carving. It’s used to cut intricate designs in wooden floor panels, fence patterns, wooden blinds, dining table and so on.

Models and Crafts

Wood laser engraving and cutting enable detailed wooden models like architectural buildings, ships, aircrafts, and trains to be intricately fabricated with fine features. For crafts, lasers allow easier creation of wooden puzzles, toys, phone cases, keychains, and more by cutting shapes and engraving designs not achievable manually.

Jewelry and Accessories

Laser can efficiently cut and shape diverse wooden components for artisanal jewelry-making and novel accessories. Meanwhile, patterns, dates, messages and so on can be precisely etched onto the jewelry surface to personalize and customize designs. Wood laser engraving and cutting enable intricate detailing on necklaces, bracelets, rings, earings, pendants and so on.

Where to buy wood?

Tips and tricks for laser processing wood

Reducing Backside Charring in Wood Laser Engraving

During wood laser engraving, the laser energy passes through the material and strikes the honeycomb platform. It is then reflected back onto the backside of the wood by a metal mesh, causing it to char and leaving unwanted and visible marks.

As these marks are a result of laser reflection, reducing them can be achieved by minimizing this reflection. Here are several methods to do so:

1.Optimize Processing Parameters. Increase the cutting speed and lower the laser power.

2.Elevate the Wood with a Nail Bed or Similar Tool. Raise the wood above the honeycomb platform for cutting, similar to using a nail bed.

3.Cut with a Knife Blade Beneath the Wood. Cutting with a knife blade beneath the wood, which is less dense than the honeycomb platform. However, it’s essential to cut from the inside out and this method may not be suitable for very small parts.

4.Cover the Backside with Decorative Paper. Place decorative paper on the backside of the wood, allowing it to absorb some of the reflected energy in place of the wood.

5.Enhance Ventilation. Improve the air assist and exhaust system to minimize the smoke and fumes between the wood and the platform.

Choosing Woods for Laser Engraving

The principle of wood laser engraving is as follows: laser energy causes the wood surface to char and darken, creating patterns in contrast to the natural wood color. If the wood has a high resin content, deeper engraving marks can be achieved.

Therefore, wood with high resin content, light color, and smooth texture can be used for various intricate vector designs and even photo engravings. Wood with lower resin content, darker color, or distinctive grain patterns may have less pronounced detail in the engravings. For achieving excellent contrast in wood laser engraving, you can choose wood like birch, maple, and cherry wood.

I had a great buying experience working with Eric Munoz, I received my sales call at the exact time it was scheduled. He answered all of my questions about the machine and the accessories. Eric went above and beyond helping work out a banking issue I was having (missed an account number on my end) . Eric definitely changed my perception of a salesperson as he was answering emails after hours! I ordered the 53/130 ,hi-res head , rotoboss, and an extra set of mirrors and lens. Now the wait for shipping.

I started out with lasers only 3 months ago and got a "hobby" sized (12"x20") laser thinking that's all I'd need. Turns out, I was VERY wrong. I setup a call with Thunder to learn more about their Nova line of machines. Aubrey was prompt and ready to answer all of my questions. She made machine and accessory recommendations. This is the first time I have spoken with another human on anything related to a laser purchase, so it was really nice to have that personal connection for such a big investment. The call was on Friday. I thought about it all weekend, then emailed on Monday morning to get the purchase started! I'm looking forward to getting my Nova 35 and pew-pewing everything!

Thunder is just great. It's a great quality machine, backed by incredible people. I've had numerous problems that I thought were catastrophic, and the patient folk at Thunder have always been super knowledgeable, and, perhaps more important, patient. My problems usually end up being a settings error. Regardless of how simple the solution, they've always taken me seriously, walked me through troubleshooting, and offered zero judgement when the problem ended up being me. Thanks, guys! I can't recommend you enough!
