Services relating to lasers and wood are becoming more in demand these days. In addition, the number of crafts and visuals that they can produce is abundant, making them a worthy option for those who need engraving. Furthermore, custom laser engraving wood products are versatile and aesthetically pleasing.

 

The Types of Wood For Laser Engraving

While wood is a consistent material, only specific variants are ideal for laser engravings. Those planning to develop a project using these will have more success using wood with stable colors and consistent grain patterns. Those types of wood allow for a more quality engraving.

 

Deciding on Standards For Cutting

The parameters for laser cutting can easily be defined by outlining a rectangle with two rounded corners. These corners should have a different shape. The graphic should then be sent to the laser machine for processing. It is crucial to lessen the cutting speed gradually to maintain high quality.

 

Preparing the Materials For Wood Cutting and Laser Engraving

Managing Debris

Working with wood for laser processing will still generate debris. This would require cleaning regularly in order to maintain a debris-free work area, or particles may end up seeping into the edges of the finished product. Therefore, it is vital to check if any wood shavings got inside the item. You can also take steps to lessen the amount of clutter you have to remove from the working area.

Sticking an application tape to the material’s surface can serve as a protective layer for the item. The machine can easily bypass this and engrave the design, preserving the quality. In addition, the tape can easily be discarded once the laser process is finished.

However, using tape for more delicate projects that have complicated patterns is not advisable. Tape is also not conducive for photo engravings. In these cases, the tape will be slashed into multiple pieces. These will be more difficult to clean up. Remember that the tape must be a variant that is easily removed, as PVCs will not work well.

The Optics and Precision

When it comes to generating products using both wood and laser, proper optics are necessary to avoid errors. People working on the project must have a precise focus. Additionally, they must be familiar with the differences between cutting and engraving. Engraving on wood using a laser requires a shorter lens and more accurate measurements. Lenses that measure 1.5″ or 2.0″ should be sufficient for use.

As for cutting, the focal length of the lens may need to increase because of the thickness. For instance, a 2″ lens will work for 1/8″ wood, while a 2.5″ lens is appropriate for 1/4″ wood.

Compressed Air for Protection

Lenses are very delicate. It is essential to protect them while working to avoid damage and other potential hazards. One way to protect them is through compressed air. Using a nozzle with a small diameter should be used for protection since it leads the compressed air towards the cutting gap. As a result, any buildup of debris will be removed more accurately. The resulting product will be of higher quality and precision because of the compressed air.

 

Maintaining Cleanliness

Laser systems require proper maintenance and care to last a long time. Therefore, cleaning them is an essential task, and the materials they get in contact with can leave a considerable mess. For example, wood resin is a very delicate and sticky material that can get into the machine. The buildup may damage the laser, which is something you want to avoid. Oils are a similar concern because of how dense they are.

A Proper Exhaust System

With the amount of gas and dust produced, laser cutting and engraving wood require the right amount of ventilation. Otherwise, the product might suffer. The machines themselves may also take damage from the foreign particles.

 

Relief Engraving and Inlays Using Wood

Relief Engraving

Woodworking leads to a diverse set of finished products. The material is enough for relief engraving, as the grayscales can adjust to the various laser power levels from the three-dimensional engravings. However, it might require multiple trials to remove the smoke residue. Nonetheless, these will be carried out with high performance.

Wood Inlays

A mosaic-like intarsia is a popular form of woodworking. It can produce high-quality designs that are aesthetically pleasing. The types of wood used for inlays have smooth surfaces, resulting in different colors and structures. The process requires the base to be engraved, followed by an overlaying of veneer or other similar material. Next, the overlay is cut and then inserted.
