Traditional laser processing often imagines a high-energy "flamethrower." This "flamethrower" melts or vaporizes materials through high temperatures. It cuts metal or wood. However, fine engraving on a fingernail-sized chip is challenging. Opening holes in paper-thin plastic film also presents difficulties. This "fire attack" causes material deformation, charring, or complete scrapping....
In-Depth Material Compatibility What Your Blue Light Engraving Machine Can and Cannot Do
A blue light laser typically refers to a semiconductor laser. Its wavelength is approximately 450 nanometers. In the world of laser engraving, this blue light engraving machine acts like a "picky eater." It shows strong enthusiasm for some materials. Conversely, it completely ignores others. This "enthusiasm" depends entirely on the...
Laser Smoke An Overlooked Respiratory Health Risk
When operating laser cutting or marking machines, most people focus on the bright light. However, as the laser beam cuts materials, pungent laser fumes rise. As an expert, I must frankly state: the laser plume generated by laser processing often presents dangers as serious as direct beam exposure. I. Nanoparticles:...
