Abstract

The invention discloses a modularized treatment device and method for selective laser melting powder of precious metal. Through guide rails installed on a horizontal base table, a mobile base table is driven by a drive device to horizontally move on the horizontal base table along the guide rails; an opening is formed in the bottom of the mobile base table, and a protective cover type recovery box is arranged above the opening; when the mobile base table moves to the part above a forming area, the opening is connected to the forming area in a butt joint mode. The protective cover type recovery box, a detachable module plate and the mobile base table form the powder treatment device together; the protective cover type recovery box stops above a laser scanning area in the machining process and forms a partial isolation area, the liquid drop spattering and powder splashing phenomena generated in the laser scanning process are isolated inside the protective cover type recovery box, and therefore the powder pollution problem in the machining process is effectively solved; unmachined powder inside a forming cylinder can be completely and fast recovered after machining.

Description

technical field [0001] The invention relates to components in selective laser melting equipment, in particular to a modular processing device and method for precious metal laser selective melting powder. Background technique [0002] Selective Laser Melting (SLM) is an additive manufacturing technology that uses metal powder as raw material. As additive manufacturing technology gets more and more attention and attention, the research and application of SLM technology is also more and more widely. The basic principle of SLM technology is to manufacture three-dimensional parts based on the method of layer-by-layer manufacturing and layer-by-layer accumulation. Before processing, the model must first be processed, that is, the three-dimensional model is sliced ​​and then the slice data is imported into the SLM equipment. The powder device evenly spreads a layer of metal powder in the forming area, and the metal powder in the forming area is scanned by laser to make it melt ins...
