The invention discloses a powder feeding and spreading device of an SLM type metal 3D printer, comprising: a forming powder spreading mechanism; a box door, which is detachably arranged on the front side of the forming powder spreading mechanism; a positioning mechanism, the positioning The mechanism is detachably set at the center of the bottom of the forming powder spreading mechanism; the filling mechanism is detachably set on the outer wall of the positioning mechanism; the powder feeding mechanism is detachably set at the bottom left of the forming powder spreading mechanism Side; feed pipe, the feed pipe shown is detachably arranged on the top of the front side of the powder feeding mechanism; powder collecting mechanism, the powder collecting mechanism is detachably arranged on the bottom right side of the forming powder spreading mechanism. When the workpiece is processed, the present invention can reduce the inner space of the molding chamber according to the volume of the workpiece, reduce the metal powder to be laid, further shorten the laying time, shorten the production cycle, reduce the cost of the metal powder, and facilitate the use of workpiece processing.
Description
technical field [0001] The invention relates to the technical field of printers, in particular to a powder feeding and spreading device for an SLM metal 3D printer. Background technique [0002] 3D printing technology is a technology that accumulates materials layer by layer to manufacture solid parts. Compared with traditional material removal technology, it does not require tools and molds, and does not require multi-process processing. The production cycle is short and complex structures can be easily processed. parts. The current 3D printing technology can be roughly divided into SLS (Selective Laser Sintering), SLM (Selective Laser Melting), FDM (Fused Deposition Modeling), SLA (Stereolithography), and EBM (Electron Beam Jet Molding). In the working process of the SLS 3D printer, it is necessary to spread the raw material powder evenly on the printing platform, and then use the laser device for selective sintering, which requires the use of a powder spreading device; ...
