Embodiment Construction

[0072] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments.

[0073] Such as Figure 1a-Figure 4 As shown, the present invention includes:

[0074] The forming table 5 is used to support the 3D printed workpiece;

[0075] Powder laying mechanism 2, used for laying raw material powder for 3D printing on forming table 5;

[0076] The wire conveying mechanism 6 is used to convey the raw material wire for 3D printing to the forming table 5;

[0077] The 3D printing head 1 is fixedly installed above the forming table 5 (for example, directly above, or obliquely above), and is used to fuse the raw material powder or / and raw material filaments with a laser beam converging on one point and then stack them on the forming table 5 into a workpiece;

[0078] The motion mechanism 3 is used to drive the forming table 5 to...

Abstract

The invention discloses an additive manufacturing system for large-size workpiece manufacturing. The 3D printing device comprises a forming table used for supporting a workpiece subjected to additive manufacturing, a powder laying mechanism used for laying raw material powder for additive manufacturing on the forming table, and a 3D printing head used for melting the raw material powder through laser beams gathered at one point and then stacking the raw material powder into the workpiece on the forming table. And the movement mechanism is used for driving the forming table to move. And the 3D printing head is kept still, and the forming table is driven by the movement mechanism to move, so that the workpiece is formed. Compared with a galvanometer scanning mode adopted by existing selective laser melting forming, the method has the advantages that a workpiece with a larger body area can be manufactured, and the forming quality consistency can be guaranteed when additive manufacturing is carried out on the edge of a forming area.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and in particular relates to an additive manufacturing system for manufacturing large-sized workpieces. Background technique [0002] 3D printing technology, also known as additive manufacturing technology, integrates computer-aided design, material processing and molding technology, based on digital model files, through software and numerical control system, special metal materials, non-metal materials and medical biological materials Extrusion, sintering, melting, light curing, spraying, etc. are accumulated layer by layer to create a manufacturing technology for physical objects. [0003] For some materials with higher melting points, high-energy beam sintering / melting is generally selected. At present, the 3D printing forming processes used to directly manufacture functional parts mainly include: laser selective sintering / melting (SLS / SLM), electron beam selective melting (EBM...
