There are many more different applications. To provide easy and on-point identification, those parts are often marked by using laser engraving.
In the electronic or medical industry, parts need to be identified at any time. It provides them the opportunity to offer their customers custom engraving, quickly. Other markers like QR codes are also often used with engraving technology.ĭue to the precise engraving work that the laser offers, jewelry industries also work with this technology.
Engraving has the advantage that even when the part is used in production or other works, the barcode will not wear down and can still be scanned for company purposes. In the production industry, laser engraving technology is often used for engraving barcodes onto certain parts. However, Laser Engraving can also be used for decorative markings or letterheads. Laser engraving is very versatile, which is why so many industries rely on this technology for production.Įngraving is often used for awards or trophies to create a clean engraving on the surface. Usually, Laser Marking and Laser Etching are used to produce text or logos onto a material part. In the end, this method produces an image with high contrast, which is permanent. Due to this reason, Laser Marking is sometimes also described as Laser Dark Marking. Laser Marking uses a beam with low power to work with the material, which causes oxidation, and the material turns black. Laser Marking compared to Laser Engraving Laser Marking is different from Laser Engraving and Laser Etching as it does not vaporize part of the material and therefore does not change the surface of the piece. With Laser Engraving the material keeps its original shape. 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.
