Laser engraving is a broad topic. There are quite a few types of lasers suited for different materials. The right choice determines how well the results turn out. In light of this premise, a common question that arises is whether a fiber laser can engrave wood.
Fiber lasers are not an ideal choice when it comes to engraving wood. In this blog, we will find out why!
Understanding Fiber Lasers and Wood
Fiber lasers are an ideal choice for cutting and engraving metal and some plastics because they use a very fine, powerful light beam. However, wood is a soft, organic material, and it doesn’t react the same way to it.
The frequency of fiber lasers is not well absorbed into wood. Instead, it burns the surface, making the wood look charred, uneven, or burnt.
Hence, fiber lasers aren’t a good choice for wood. Other lasers, like CO₂ lasers, work much better for wood because of their unique properties and appropriate laser wavelengths.
Risks of Using Fiber Lasers on Wood
Let’s look at the top three risks of using fiber lasers on wood:
- Fire Hazard
Fiber lasers are very strong and not recommended for organic materials like wood. The short wavelengths that come in contact with wood can potentially turn into a fire hazard. This is considered extremely dangerous. - Poor Quality Marks
Even if it doesn’t catch fire, a fiber laser burns the wood unevenly. The marks often look messy, too dark, unclear, or sharp. Hence, failing to provide the desired results. This can reflect badly on your reputation as a laser engraver. - Material Damage
Apart from poor engraving, the laser will ruin your wood piece. This means you waste your material and lose money or supplies.
Which Is The Best Laser for Wood Engraving?
CO₂ lasers deliver high-quality and precise engravings on wood. Due to their specific wavelength, they are an industry standard choice for organic materials, i.e., wood.
Why is CO₂ Laser Considered Ideal for Wood Engraving?
Here are some reasons why CO₂ lasers are the best choice to engrave wood:
- Clean, Clear Engravings
CO₂ lasers remove a thin layer from the surface, creating neat, sharp lines and dark engravings. Because the laser is well-absorbed by wood, there’s less risk of deep burns or messy edges. - More Control
CO₂ laser settings can be adjusted based on how deep you want to engrave. This gives the professional more control and makes it a versatile choice for different project needs, such as deep cuts for shapes or gentle etching for fine details like text or logos. - Works on Many Materials
Besides wood, CO₂ lasers work well on leather, paper, acrylic, cork, and other natural materials. This makes them very useful for engravers who need to engrave or cut different items.
Overall Insight
Fiber lasers are not an ideal choice for engraving wood. They don’t interact well with organic materials, often causing burning, uneven marks, or even fire. CO₂ lasers, on the other hand, are a better and reliable option to engrave wood.
