1. Product introduction
The HonorPrint M series metal powder melting rapid prototyping system is composed of: laser, galvanometer scanning system, host forming room, powder feeding mechanism, dust removal device, control system, computer and 3D printing special software. The schematic diagram of the HonorPrint M series forming process is shown in Figure 1. During the forming process, in order to prevent the metal powder material from being oxidized, the forming cavity should be sealed and filled with protective gas. When forming, first spread a layer of powder material on the workbench with a scraper. Then, under the control of special software for 3D printing, the laser beam scans the solid part of the powder based on the cross-sectional profile information to raise the temperature of the powder to the melting point. Above, the scanned powder melts and then drops below the melting point, bonding to each other to form a sintered surface. The powder in the non-scanned area is still loose and serves as a support for the workpiece and the next layer of powder. After the forming of one layer is completed, the workbench is lowered by the height of one layer, and then the next layer is laid and formed. This cycle continues to form a three-dimensional workpiece.
