Description

technical field

[0001] The invention belongs to the technical field of advanced additive manufacturing, and more specifically relates to an automatic powder feeding system and printing method for metal 3D printing. Background technique

[0002] The basic principle of SLM (selective laser melting, selective laser melting) technology is: first use pro / e (Pro / Engineer, a kind of mechanical automation software), UG (CAD CAM CAE, interactive CAD / CAE system) on the computer , CATIA (ComputerAidedThree-dimensionalInteractiveApplication interactive CAD / CAE / CAM system) and other three-dimensional modeling software to design the three-dimensional solid model of the part, and then slice and layer the three-dimensional solid model through the slicing software to obtain the contour data of each section. Generate a filling scanning path, the equipment will follow the filling scanning path, control the laser beam to selectively melt the metal powder materials of each layer, and gradually s...
