Achieving High Quality Deep Engraving with Multi-Pass Technique

Welcome to the latest laser hack video by Don, from Trotec Laser Canada. In this tutorial, Don will show you how to achieve high-quality deep engraving using a multi-pass technique. This technique is especially useful when processing materials that are prone to burning or charring due to excessive heat generated by the laser. Don starts by demonstrating the difference between using a single high-powered, low-speed laser pass and running multiple passes to improve quality. Using a piece of solid cherry wood, he runs a speedy 400 laser with a 2-inch lens at 100 power and 10 speed, 1 kilohertz at 500 DPI, with a single laser pass. The result is a dark charred look, caused by the excess heat generated by the laser machine running at full power and low speed. To prevent excessive heat buildup and to achieve a cleaner finished look, Don recommends using the multi-pass technique. In the second example, Don uses the same settings but with the laser speed set at four times the rate of the first example, at 40% with four passes. The result is a removal of 25% of the material with each laser pass, producing a much cleaner finished look at a similar processing time. Don also demonstrates the effectiveness of this technique in a 3D relief image. By engraving the image at 100 power, 10 percent speed, one kilohertz at 500 DPI with a single pass, the image loses details due to excessive heat. However, by using the multi-pass technique, Don achieves a much cleaner and detailed engraving with four laser passes. This laser hack technique is useful for any material that requires deep engraving without compromising on quality. It reduces the heat generated by the laser machine, preventing burning, charring, or melting of the material, resulting in a cleaner and more defined finished engraving.
