laseretched

Laseretched refers to objects or markings produced by laser etching, a material modification process that uses a focused laser beam to remove material or alter a surface to create signs, text, patterns, or textures. The term can describe shallow surface marks as well as deeper engravings, depending on the material and processing parameters.

The process relies on precise control of laser parameters such as power, speed, pulse duration, wavelength, and focal distance. Interaction with the workpiece can cause ablation, oxidation, melting, or phase changes, resulting in a permanent mark with varying depth and contrast. Different approaches include continuous-wave marking and pulsed engraving, which yield different textures and edge definitions.

Materials commonly etched include metals (steel, aluminum, titanium), polymers (plastics and acrylics), glass, wood, leather, and certain ceramics and coatings. Laseretched features range from high-contrast gray or dark marks on metals to color changes on some polymers or glasses, sometimes requiring coatings or post-processing to enhance readability.

Applications span serial numbers and branding on components, product labeling, decorative or artistic engravings, and micro-patterning for electronics or medical devices. The technique offers high resolution, repeatability, and the ability to mark complex shapes without physical tooling.

Advantages include a non-contact process, rapid production, and the ability to programmatically change marks. Limitations involve heat-affected zones, potential surface or color changes, material incompatibilities, and the need for specialized equipment and safety measures. Appropriate laser safety practices, ventilation, and protective equipment are essential when performing laseretched work.
