Laser engraving machines use laser technology to engrave. The principle is to use laser heat energy to burn or cause chemical changes on the engraving surface to produce engraving marks. Using a laser engraving machine can control the engraving text, pattern, and size, and the engraving pattern is also relatively fine.
Small DIY laser engraving machines generally use blue light engraving lasers. It uses a semiconductor laser diode as a laser source to produce a high-energy blue laser beam to cut and engrave the surface of the object. Blue lasers have shorter wavelengths and therefore higher energy density. This makes it have better cutting and engraving effects on certain materials, especially for some materials with higher hardness, such as glass, ceramics, etc. So, how should we choose a laser head?
The 5 W optical power laser engraving head is suitable for light and thin materials such as paper; the 10 W optical power laser engraving head
Suitable for leather, acrylic and other materials; 20 W optical power laser engraving head is suitable for hardwood board, stainless steel and other materials; 30 W optical power laser engraving head is suitable for glass, stainless steel and other materials; 40 W optical power laser engraving head is suitable for organic matter, Most materials such as metals and minerals.
