The laser engraving machine is built specifically for engraving products with a generic or custom design. There are different machines to suit different materials and effects. Generally these machines work by loading the design you want engraved into the unit's computer, where you can then adjust the dimensions of the design. The engraver leaves a cavity that reveals an image within the material.
Laser cutters are very similar to laser engravers, the main difference between the two is what their primary use is. Laser cutting is ideal for cutting through thin materials including plastic, wood, textiles and more. Many choose laser cutters over plasma cutters thanks to their higher precision and low energy usage. Laser cutters are used to create all kinds of products, including table numbers, unique clock faces, monogrammed or geometric coasters, decorative-shaped mirrors, jewellery and much more.
If you're looking to tag a machine or equipment without engraving or cutting the material, then a laser marker is most likely what you need. Laser marking only slightly alters the material's properties or appearance for a more subtle finish. The surface of the material is left intact. A laser marker is ideal for creating QR codes, logos, barcodes and other ID requirements.
So when it comes to laser cutting and marking, whether you choose a laser cutting machine or a laser engraving machine really depends on what your primary direction is. Both machines can be used for either purpose, so just make sure you have the right one for your main purpose. The laser marking machine is very different from the other 2 types of laser cutting and marking machines, as this type is primarily used for medical equipment and for creating identification tags.
These machines are ideal for commercial use, thanks to their automation, technology and size. For hobbyists, there are portable/tabletop versions of these machines available.
