When a material (in most cases, metal) is etched, it expands and creates a raised cavity. However, it functions as a tool that melts the material rather than vaporizes it. Is Laser Etching the same as Laser Engraving? Laser Etching may be used as a synonym for Laser Engraving. There are laser machines that can laser cut and engrave but would still need a 2D file to function. Many different fields such as aerospace, automotive, medicine, or electronics rely on this technology as it cuts other materials and delivers a smooth finish. Laser Engraving Laser cutting, as the name implies, creates clean cuts into the material. The model contained in the file will be converted into dots and the distance between them determines how deep the engraving will be. So you have to use formats like jpg, pdf, png, or ai that are 2D files. What type of file do you need for Laser Engraving? Laser Engraving systems can not read any 3D files like. While the first one uses vector images to follow paths or lines, the second vaporizes the material to create an image into the material or give the design a 3D-like impression. Two different forms should be distinguished: line engraving and surface engraving.
When the Laser Engraving process starts, the beam creates a high heat that burns or evaporates the surface according to the image from the file. However, before the actual engraving process can begin, the machine needs a file sent from a computer to the machine’s controller, which then positions the laser. It is a subtractive manufacturing method. The aim of Laser Engraving is to engrave a specific picture or logo onto a selected material.
