Abstract

A multi-workpiece 3D printing device comprises a powder laying device, a laser emitting device, a scanning galvanometer device and at least two bearing devices. Each bearing device is provided with a powder laying area, the powder laying device is used for alternately laying base material powder on the at least two powder laying areas, the laser emitting device is used for emitting laser beams, and the scanning galvanometer device is used for focusing the laser beams to the at least two powder laying areas according to a preset path. The invention further provides a multi-workpiece 3D printing method.

Description

technical field [0001] The present invention relates to a 3D printing device and a 3D printing method, in particular to a multi-workpiece 3D printing device and a multi-workpiece 3D printing method. Background technique [0002] 3D printing technologies such as laser selective melting (SLM), laser direct deposition (LDM) and electron beam powder bed fusion (EBM) can print complex and high-precision integrated parts, and are widely used in aerospace, biological Medical and industrial manufacturing fields. When forming a part with laser selective melting technology, the powder is generally pushed to the forming area of ​​the part by moving the powder spreading scraper, and then moved back to the initial position. After the printing of the last powder moved to the forming area is completed, the powder is pushed to the part again forming area. In this way, the powder spreading scraper can only spread powder to one forming area during the printing process, and the printing effi...
