The invention discloses an additive / subtractive material mixed manufacturing platform, which is used for the precise manufacture of gradient material complex parts, including a molding cylinder, a molding substrate, a multi-material powder feeding system, a multi-material laser scanning system, a tool system, and a platform base. It is characterized in that: the molding substrate is installed on the molding cylinder through a moving mechanism, the multi-material powder feeding system is movably connected to the platform base, and the multi-material laser scanning system is fixedly connected to the platform On the base body, the tool system is movably connected with the platform base body. The platform of the present invention changes the powder supply mode of single material powder in the existing selective laser sintering / melting (SLS / SLM) technology and the status quo of low geometric accuracy and surface quality of additively manufactured parts, and realizes the macro of complex parts of gradient materials. The integrated manufacturing of microstructure improves the material utilization, complexity and functionality of parts, while improving the geometric accuracy and surface quality of parts.
Description
technical field [0001] The invention relates to an additive / subtractive material hybrid manufacturing platform, in particular to an additive / subtractive material hybrid manufacturing platform for complex parts with gradient materials, and belongs to the technical field of additive / subtractive material hybrid manufacturing equipment. Background technique [0002] Additive manufacturing technology is based on the forming principle of CAD data layer-by-layer accumulation of materials to directly manufacture solid parts, which provides a new opportunity for the development of manufacturing technology from traditional macro-shape manufacturing to macro-microstructure integrated manufacturing. With the improvement of parts performance requirements, composite Materials or gradient material parts have become products that urgently need to be developed, and additive manufacturing has a micro-unit accumulation process. Each accumulation unit can realize the compounding of different mat...
