Abstract

The invention discloses an optional laser sintering 3D printer. The optional laser sintering 3D printer comprises a rack and at least two light path units. The at least two light path units are arranged on the rack, and comprises a first light path unit and a second light path unit which are adjacently arranged. The scanning areas of the first light path unit and the second light path unit are partially overlapped at least. The 3D printer is provided with at least two light path units, each light path unit is responsible for the scanning and printing work of respective areas, the scanning areas of the adjacent light path units are partially overlapped at least, and therefore the printing size of the printer is increased, and then the printing efficiency is improved. The increase of the printing size is beneficial to meeting printing of large-size engineering machine parts.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a selective laser sintering 3D printer. Background technique [0002] 3D printer, also known as 3D printer, is a rapid prototyping equipment based on digital model files, using molding materials, and constructing three-dimensional entities by layer-by-layer printing. Among them, selective laser sintering (SLS) is a kind of additive manufacturing technology. Its working principle is to use the three-dimensional digital model of the part and use a high-power laser beam to heat and sinter the layer-by-layer powder according to the cross-sectional path of the part to form the part. [0003] SLS technology is widely used because of its wide selection of powder materials, simple manufacturing process, and no need for support structures. SLS technology can quickly produce precision parts without making metal molds by sintering precision casting wax powder, PS, PC and other powders. ...
