First, what is Laser Engraving & why would you use a Laser over traditional engraving?
Traditional rotary engraving uses a machine equipped with a bit to engrave the surface. It’s been around for over a hundred years. But it has limitations with materials. We use a laser which uses a very intense beam of light to transform the surface of a substrate. The term “LASER” stands for Light Amplification by Stimulated Emission of Radiation. Lasers amplify light by absorbing and radiating energy. Using a concentrated energy source like CO2, energy in the form of light is transmitted through a series of mirrors. The highly concentrated beam of focused light or laser, melts or evaporates the top layer of material to reveal a contrasting color or material on the layer below.
Using our Trotec Speedy 400, 120 watt lase we are able to engrave on mat, acrylic, glass, laminates, leather, paper, plastics, stone, textile and wood. See the full list of materials we can engrave below.
We can also “mark” on stainless steel, vs. “engrave”. Using uncoated stainless steel, a black mark can be created by spraying the surface with a specially formulated liquid, lasering the image at the correct intensity and speed, then washing off the excess liquid with water will reveal a black image. The heat generated from the laser chemically bonds the applied liquid to the top layer of the stainless steel which will not scratch or wear off.
