how do laser engravers work?
In: 2
Laser engravers are really powerful lasers controlled by computers.
A computer turns the laser on and off really rapidly, causing tiny explosions on a material’s surface. Over time, these explosions evaporate enough material to leave an engraved image.
The computer can also control where the laser is pointing, or move a platform that the material is on, to “draw” an image with the laser.
