The 1990s mid-term, the newest rapid molding device for the technologies such as actually utilize photocuring and paper layer folded.It with it is common
Print job principle is essentially identical, equipped with " printed materials " such as liquid or powder in printer, after being connect with computer, passes through computer
Control from level to level stacks up " printed material ", and the blueprint on computer is finally become in kind.
So-called 3D printer and normal printer operation principle are essentially identical, and only printed material is somewhat different, commonly
The printed material of printer is ink and paper, and equipped with " the printing material that metal, ceramics, plastics, sand etc. are different in 3D printer
Material " is that raw material true can be " printed material " from level to level by computer control after printer is connect with computer
It stacks up, the blueprint on computer is finally become in kind.Generally, 3D printer is " can to print " to go out true 3D
A kind of equipment of object, such as one robot of printing, printing toy car, print various models, even food etc..Institute
