Multi-head branch-control 3D printer

Abstract

The invention discloses a multi-head branch-control 3D printer. Longitudinal guide rails are two guide rails symmetrically distributed along the middle positions of transverse guide rails. Each longitudinal guide rail is symmetrically provided with two printing head mounting sliding blocks, wherein a 3D printing head is mounted on each printing head mounting sliding block. The four 3D printing heads on the two longitudinal guide rails complete printing in four areas of a printing platform. Every time printing of one layer is completed, the printing platform is driven by a power mechanism to rotate by 3.6 degrees, and therefore the printing areas corresponding to the four printing heads are stacked at the joint of the two adjacent printing areas of the lower layer. The four printing heads of the multi-head branch-control 3D printer work at the same time and do not generate interference to one another, and the printing efficiency is greatly improved; and the printing platform is arranged to be rotatable, and therefore after printing work of one layer is completed every time, the printing platform rotates by a certain angle, the printing area of each printing head is changed, staggered stacking between the different printing layers is formed, and the strength and stability of printed products are improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a multi-head controlled 3D printer. Background technique [0002] 3D printing technology was born in the United States in the 1980s, and there was a first wave of small climax immediately after that, and many 3D printing companies emerged in the United States soon; in 1984, Charles Hull began to develop 3D printing technology, and in 1986, he set up his own company. Founded the world's first 3D printing technology company (3DSystems is also one of the current 3D market leaders), and released the first commercial 3D printer in the same year. In 1988, Scott Crump invented the FDM hot-melt extrusion molding technology, and in 1989 established Stratasys (NASDAQ: SSYS), another 3D printing listed company, which sold the first commercial 3D printing machine in 1992. printer. [0003] Our country began to study 3D printing technology in 1991. The name at that time was Rapid Protot...
