Lasers Mark Wood|Laser Marking on Wood: Controlling Burn Marks and Enhancing Clarity

Want to use a laser engraver to carve a fine pattern into wood, but always end up with burn marks? This article analyzes the reasons why burn marks form when laser engraving wood, and offers practical solutions.The course teaches you how to optimize the settings and use the machine to reduce carbonization and increase the precision of the carving, giving woodwork a more professional look.

Wood, as a natural material, is prone to charring when subjected to the high temperatures of laser marking, which affects the appearance of the product and reduces its value.To resolve this problem, one must first understand the carbonization characteristics of wood. The type of tree, moisture content, and grain direction all affect how the laser is absorbed.Experiments showed that keeping the power output in the 60-75 % range and the scanning speed at 400-600 mm / s was the best way to balance depth of cut and scorching.In actual operation, it is suggested to use a layered carving method, first using a low power setting to create the base, and then progressively deepening the image. This can both avoid using too much power at once, and ensure that the outline of the image is clear.

The key to improving resolution is adjusting the focus and pre-processing the material.Periodically check the position of the focusing lens with a calibration card to ensure that the laser beam is in the most focused state.For softwoods such as pine, it is best to wipe the surface with a damp cloth and let it air dry before carving to reduce the amount of smoke residue.With hardwoods, the use of a rotary jig is recommended to keep the carving surface level and avoid local loss of focus caused by slight tilting.In terms of software settings, you should set the DPI to 500 or higher and enable the "anti-aliasing" function, which will make curves and corners smoother and more natural.

The advanced techniques include the use of auxiliary gases and the template positioning method.A small fan set up near the carving area can remove combustion products, reducing carbonization at the edges.For patterns that need to be engraved repeatedly, first use a low-power beam to trace the outline and then fill it in; this greatly increases consistency between finished products.Finally, it should be noted that there may be differences in wood density between different batches, so it is essential to test the parameters on the trimmings before beginning formal processing.

How Much Does Humidity Affect Wood?

Humidity is a key factor in determining the moisture content of wood, and has a direct bearing on the stability and durability of the wood.The book covers everything from humidity monitoring to drying methods to solutions to common problems, and helps woodworkers avoid warping and cracking, and improve the quality of their products.
