The core idea of 3D printing technology originated from America. 1982, j.e.Blanther put forward the idea of layered manufacturing in his patent. 1902 Carlo Baese put forward the principle of photopolymer as manufacturing material.
1968, Charles Hull successfully modeled digital data in three dimensions, introduced light curing method, and founded the world's first 3D printing equipment company in the same year. In the following two or three decades, there appeared "fused deposition", "selective laser sintering" and the world's earliest full-color 3D printing technology "stereoscopic inkjet printing".
Principle and technology of 3D printer
Ordinary printers used in daily life can print plane objects designed by computers, while the so-called 3D printers have basically the same working principle as ordinary printers, but the printing materials are somewhat different. The printing materials of ordinary printers are ink and paper, while 3D printers are filled with different "printing materials" such as metals, ceramics, plastics and sand, which are real raw materials. After the printer is connected to the computer, the "printed materials" can be superimposed layer by layer through computer control, and finally the blueprint on the computer can be put on it.
