The number of points in the magnet pen can be controlled and adjusted. The magnetic system has less extremity and in the set against less noise pollution than the pneumatic system.
Laser engraving
In the laser method, the ray is produced by stimulating the laser generating material by electric discharge or the radiation of a lamp in a chamber, and the beam is reflected using a mirror to buy the indispensable animatronics to become a fresh stream.
