high speed industrial plastic Laser Melting rapid prototyping system metal 3D printer

The laser beam emitted by the laser is injected into the acousto-optic deflection modulator through the reflector. At the same time, the binary image text dot matrix information sent by the computer is sent to the font generator from the interface to form the binary pulse information of the desired font. The signal generated by the synchronizer controls 9 high-frequency oscillators, and then is added to the acousto-optic modulator through the frequency synthesizer and power amplifier to modulate the laser beam emitted by the reflector. The modulated light beam is shot into the multi-faceted rotating mirror, and then focused by the wide-angle focusing mirror and shot onto the surface of the photoconductive drum (selenium drum), so that the angular velocity scanning becomes the linear velocity scanning, and the whole scanning process is completed.

The laser printer was born out of the laser phototypesetting technology in the late 1980s and was popular in the mid-1990s. It is a print output device that combines laser scanning technology with electronic photography technology. Its basic working principle is that the binary data information transmitted from the computer is converted into video signal through the video controller, and then the video signal is converted into laser drive signal by the video interface/control system. Then the laser scanning system generates a laser beam containing character information, and finally the electronic photography system makes the laser beam image and transfer it to the paper. Compared with other printing devices, laser printers have the advantages of fast printing speed and high imaging quality; However, the use cost is relatively high.
