III. Wood Laser Machine

When we are talking about wood engraving and laser cutting, discussing wood laser machines is very important. There are usually different laser cutters having diverse capabilities. Generally, wood laser machines are cost-efficient and easy to maintain as compared to those for acrylic cutting. 

Some laser cutters are multipurpose and work on wood, metal, and acrylic. While some edges have limited capabilities in terms of wood thickness, they can easily handle them. However, if we generally look at the wood laser engraving and cutting options, you have the following options: Diode lasers, fiber lasers, and CO2 lasers. 

Which one is better?

Let’s explore. 

1. Fiber Laser Wood Engraving Machine Vs. CO2 Laser Wood Engraving Machine

Adopting Japan’s imported motor for 5G acceleration allows for high superior engraving speed in the industry.

Laser Type: RF CO2

Work Area: 559×381 up to 813x508mm

Laser Power: 30w, 55w

Z-axis: 185mm

Regarding power, fiber laser is on the top, and this laser-cutting machine for wood is the most expensive of all technologies. The fiber laser wood-cutting machines employ a diode bank for creating laser beams. Therefore, a fiber laser is an advanced form of the diode laser. Operating this technology requires around 2000-4000 watts of output power. 

On the other hand, if we talk bout CO2 laser, it is less costly and a bit less efficient. Although the technology is ancient, it is widely used for laser wood cutting and engraving. The CO2 gas inside the discharge tube of the cutter engraves on the wood and other materials. It also contains other gases, but CO2 has the highest proportion. 

If we have to determine which is better, fiber laser has advanced technology and capabilities. However, the best machine doesn’t mean the best option. Fiber laser is effective when you want to engrave on fiberglass, plastics, rubber, silver, chrome, ceramics, and metals like aluminum, meta sheets, brass, copper, stainless steel, etc. It also works on wood but is not suitable for small businesses. On the other hand, CO2 laser wood cutting and engraving machines are ideal for cutting all types of wood. Other materials you can cut with the laser cutting machine are bone, rubber, acrylic, brick, glass, fabric, aluminum, etc. 

Besides the cost reasons, Fiber laser should not be used for wood engraving as it poses serious fire hazards due to uncontrolled beam absorption during the engraving process. Besides, fiber can leave unpleasant marks on wood during the engraving process. 

2. Laser Wood Cutting Machines

The laser wood-cutting machines also vary depending on the thickness of the wood and the cutting material they can handle. In the case of wood-cutting devices, there are large and small wood laser cutters. The wood-cutting machines are usually categorized based on type, power, working area, and usage.

1) Large Wood Laser Cutter

Large wood laser cutters are often used for industrial use and are more powerful. These wood laser cutters have a large working area and more power. When it comes to laser cutter machines for wood, CO2 laser cutters are a better option. They come in capacity ranging from 40W to 300W. However, if you want it for hobby or professional use, the range should be between 30 to 120W. The higher the laser power, the more thickness the wood laser cutter and engraver can handle. 

2) Small Wood Laser Cutter

V. How To Laser Engrave Wood?

Whether you want to know about laser wood engraving for personal projects or getting in the game as a professional, here are the things you need to know:

1. Wood Properties

When choosing wood for an engraving project, it is essential to study its properties. It will not only save you from the struggle of failed efforts but also save you money. Besides, please put your hands on the ideal wood for engraving. 

Irrespective of wood type, here are a few properties you need to consider before picking up a wood-burning laser machine:

1) Aging Of Wood(Growth Rings and Knots) – Pick the wood with fewer knots and growth rings as it is easier to cut, engrave, and use. The fewer irregularities and blemishes, the better.

2) Coloring And Grains Uniformity –The density, coloring, and grain direction of wood can impact the result of the wood engraving project. Therefore, look for wood with higher color and grain uniformity to get the best results. 

3) How Much Moisture? –Moisture content of the wood also affects the final results. Ideally, you should go for dry wood to have darker engraving results. 

4) What is the Oil and Resin content of wood? –The impact of resin and oil content in wood is also amplified. The higher the content, the better the results.

2. Wood Types

You cannot randomly pick any wood and put it under the laser beam for engraving. Campfire wood can set everything on fire, and soaked wood will result in failed attempts. What are the ideal types of wood you should go for when starting a wood engraving project?

Generally, wood is categorized into the following types: soft, hardwood, natural wood, Bamboo, cork, and Balsa. Here are the appropriate wood types you can pick from:

· Birch, pine, cedar, fur, and redwood come under the softwood category. Each wood type has its properties and different impact on engraving and painting. If your project requires softwood, you can pick any of these woods.

· If you want hardwood, birch is a type that comes under both softwood and hardwood categories. However, other types of hardwood are mahogany, cherry, ash, walnut, and oak. Mahogany is ideal for laser engraving but is rarely found among all types. Oak is also easy to work with.

  • Bamboo is widely used to make cutting boards that are extensively used in engraving projects.
  • Cork is the type that is fire-resistant and elastic as well.
  • Balsa is lightweight, cheaper, and perfect for laser cutting. 

3. Laser Engraving On Wood: Applications

When you are working on a wood engraving project, there are certain things you must consider. For instance, the edge burn due to engraving, wood type, sheets, the density of wood, thickness of wood, etc., impacts the outcome. 

Here are the general implications and applications when you get your hands on a wood engraving project:

4. Choosing The Wood

We already mentioned that density, growth rings, and knots determine how easily you can engrave on the wood. Irrespective of which wood laser cutter machine you opt for, choosing a flat wood with fewer irregularities and knots is better. Similarly, try to find flat sheets if you have to work with plywood. 

5. How To Avoid Edge Burn

Edge burn refers to the darkening of the wood edges due to the vaporization of moisture from the wood. Edge burns are common when you use a wood engraving laser machine on any wood. You cannot eliminate the edge burn but minimize it by choosing drier woods having lower resin and oil content. 

6. Managing Thickness And Density Of Wood

You can purchase any wood laser cutter and engraver, but the wood you come across can vary depending on the projects’ availability and requirements. Each laser cutter handles wood thickness differently, and wood density also impacts the outcome. 

If you use thick wood than the maximum limit your laser engraver can cut, you can cut the sheets using multiple passes. Besides, you will have to manage your machine’s settings according to the hardness and density of the wood. 

7.Wood Finishing Tips

How do you ensure that engraved wood’s final look is neat, aesthetically pleasing, and how you want it to be?

Here are wood finishing tips for you:

1. Once you complete the engraving, sand the wood surface and apply a finishing coat to lock the engraving. However, ensure to avoid over-sanding as it will damage the engraving. 

2. Staining the final engraved wood can enhance natural beauty. You can apply paints or stains to give that final aesthetic touch. 

3. Use a rag to rub the wood to eliminate excess soot after completing the engraving. 

8. Laser Engraving On Wood: Settings 

We already talked about the power, working area, and wood thickness in choosing wood laser engraving machines. When working on a project, you have to adjust the laser power, speed, and other settings according to the type of wood you are using, density, thickness, and cutting/engraving needs. Read the manual and instructions that come with your laser etching machine for wood.
