In addition, the light source in the DLP technology uses a DMD chip, which is expensive, and the manufacturing cost of the printer is high. The LCD technology has the advantages of high curing and forming speed and high forming precision. But its shortcoming is very obvious, uses LED lamp pearl light source, and the illumination area is little, and the shaping size is little, and in addition, the light source launches illumination also can produce heat radiation simultaneously, reduces LCD screen's life.
