Tips For Laser Engraving And Laser Cutting Wood

Type Of Wood That Can Be Used

For you to start laser engraving or laser cutting wood, you need to choose a plank of good wood. Because wood is a natural material, numerous properties such as density and resins content must be taken into account during processing.

As a general rule, the better and more even the laser engraving result will be the more consistent the coloration and texture of the wood.

Soft wood such as Poplar, Hard wood such as oak, Confirious woods such fir, Veneers, or plywoods, can all be used for good results.

Engraving And Cutting

As a general rule, laser engraving on hard woods will generate dark markings, whereas laser engraving on soft woods will produce light marks. And for the brighter the laser cutting edge, the drier and more resin-free the wood.

Things To Remember

1. Preperation of the material: The sticky dust produced by the laser wood should not adhere to the engraving item as well. Simply apply an application tape to the working area to provide short-term surface protection that is readily etched.

It is easily eliminated after laser processing. Application tape is ideal for larger-area laser engraving and laser cutting.

1. Choosing the right laser optics: Sublimation is used in the laser cutting of wood. Accurate focusing and the proper selection of optics are critical for this operation. There must be a differentiation between engraving and/or cutting.

The lower the focal length of the lens, the finer the details. The longer the focal length of the lens utilised, the thicker the material.

1. Using compressed air: The use of compressed air is highly suggested for laser cutting wood. To protect the lens, a comparatively tiny nozzle should be utilised. The pressurised air is also directed directly into the cutting gap due to the narrow nozzle diameter.

Dust and gas are eliminated more quickly, and laser cutting quality is greatly enhanced.

1. Regular cleaning: When laser treating wood, cleaning hardware and optics are critical. Because of the resins and oils in wood dust, it is particularly sticky, and it tends to settle within the laser machine.

1. Use proper exhaust: During laser engraving and cutting wood, dust and gases are created that must be adequately removed, necessitating the use of an exhaust system.
