Selective area laser sintering molding machine with multiple feeding and blanking systems

Abstract

A selective laser sintering molding machine with multiple feeding and blanking systems. The machine has multiple feeding systems, and each feeding system places a powder material, which can realize the use of any one of the multiple feeding systems. The workpiece is made of powder materials or the same workpiece is made of different materials in multiple sets of feeding systems, thereby reducing the trouble of time-consuming and laborious replacement of materials, and promoting the research and development of new materials and various functional materials, greatly improving production efficiency and improving equipment. utilization rate.

Description

technical field [0001] The invention relates to an area-selective laser sintering molding machine with multiple feeding and blanking systems, belonging to the field of additive manufacturing. Background technique [0002] 3D printing technology has recently been widely recognized and developed rapidly. In 3D printing technology, powder selective laser sintering technology is the fastest growing and most dynamic molding technology. The powder materials that can be processed are: polystyrene, nylon, resin There are various materials such as sand, ceramics, metals, etc. Metal powders include stainless steel, high-temperature alloys, titanium alloys, aluminum alloys, etc., and each type has different grades. At present, one equipment uses one material to process workpieces of this material. To process workpieces of another material, it is necessary to clean up the original powder material and wipe off all parts in contact with the powder, including the feeding system, forming cy...

[0002] 3D printing technology has recently been widely recognized and developed rapidly. In 3D printing technology, powder selective laser sintering technology is the fastest growing and most dynamic molding technology. The powder materials that can be processed are: polystyrene, nylon, resin There are various materials such as sand, ceramics, metals, etc. Metal powders include stainless steel, high-temperature alloys, titanium alloys, aluminum alloys, etc., and each type has different grades. At present, one equipment uses one material to process workpieces of this material. To process workpieces of another material, it is necessary to clean up the original powder material and wipe off all parts in contact with the powder, including the feeding system, forming cylinder, dropping hopper, powder spreading system, etc., which is very time-consuming and laborious, and every The workpiece can only be made of the same material. If multiple feeding systems can be used to feed materials, each feeding system is a kind of powder material. When processing workpieces of different materials, there is no need to clean up the original powder, which will greatly improve production efficiency and improve equipment. Utilization rate; if it can be realized that a workpiece can be made of different materials, it will greatly promote the development and manufacture of various new materials and various functional materials
