SLM selective 3D printer huge size 3D printing machine

The laser printer is composed of laser, acousto-optic modulator, high-frequency drive, scanner, synchronizer, optical deflector, etc. Its function is to modulate the binary dot matrix information sent by the interface circuit on the laser beam, and then scan it on the photoreceptor. The photosensitive body and the photographic mechanism constitute an electronic photographic transfer system, which transfers the image of pictures and texts on the photosensitive drum to the printing paper. The principle is the same as that of the copier. Laser printer is a non impact output device that combines laser scanning technology with electronic imaging technology.

The laser printer has high voltage circuit and high temperature circuit, so the electronic radiation and thermal radiation have a certain impact on the human body. Pay attention to the protection of pregnant women and children or keep away from these devices. In the process of printing, high temperature heating will bring out some powder and ink particles, which is bad for breathing. It should be avoided to work at the laser printer for a long time.
