3D printing forming system capable of being used for multi-material composite manufacturing

Abstract

The invention discloses a 3D printing forming system capable of being used for multi-material composite manufacturing, and the 3D printing forming system comprises a forming table used for supporting a workpiece subjected to 3D printing; the powder laying mechanism is used for laying raw material powder for 3D printing on the forming table; the wire conveying mechanism is used for conveying a raw material wire for 3D printing to the forming table; the 3D printing head is used for melting the raw material powder or / and the raw material wires by using the laser beams gathered at one point and stacking the raw material powder or / and the raw material wires into a workpiece on the forming table; the movement mechanism is used for driving the forming table to move in the X-axis direction, the Y-axis direction and the Z-axis direction. 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 an existing 3D printing system, the 3D printing forming system disclosed by the invention can realize multi-material composite manufacturing of conveying wire materials and laying powder materials which are different materials, can realize large-size workpiece forming, and ensures the forming quality consistency in a forming area.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and in particular relates to a 3D printing forming system that can be used for multi-material composite manufacturing. 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 selectiv...
