The secret behind the power of a laser lies in the scattering of the light. Laser pointers, overhead projectors or scanners at the supermarket checkout also use laser beams, but these are more widely scattered, so they are much weaker and it is harmless to look into them with the naked eye.

Attention: With a laser engraving machine you can engrave your object, but not necessarily cut it. It depends on the thickness of the material. With most engraving machines, the engraving depth is only about 1 mm.

This is different with a laser engraving device. A laser engraver focuses the light beams so tightly that they develop tremendous force, burning, discoloring, or vaporizing the material being worked on, creating the desired pattern. For this reason, it is essential to wear good safety goggles when operating a laser engraving machine. The retina must be protected from the laser radiation.

Which is better: safety goggles or built-in laser protection plate?
In order to protect the eyes from the dangerous laser radiation, wearing protective goggles is strictly recommended in various laser engraving machine tests. Alternatively, some engraving machines are supplied with a built-in laser protection plate.

very effective and reliable protection against laser radiation
Protective plates are often of higher quality than the protective goggles supplied

the protective plate only protects on one side of the device
therefore you have hardly any freedom of movement when editing
if you want to be protected from any direction, we recommend a good pair of safety glasses

What are the differences in laser engraving machines for different materials?

When you buy a laser cutting machine, you should first consider what material you want to engrave. Not every laser engraving machine is suitable for every material. CO2 engravers are generally not that expensive, but are only suitable for lighter materials. Particularly hard material must be processed with a fiber laser, which is usually significantly more expensive.
