Problems solved by technology

The existing quantitative powder coating has mechanical quantitative and electric quantitative. The quantitative method of mechanical quantitative is only suitable for 3D printers of one material, and is not suitable for different materials and different amounts of powder; electric quantitative can be applied to different materials and different amounts of powder. Quantitative, but complex structure and high equipment requirements

Abstract

The invention discloses a laser sintering forming machine and belongs to the field of additive manufacturing. The laser sintering forming machine comprises an upper cylinder block, a lower cylinder block, a working table and a telescopic structure, wherein the working table is fixed in the lower cylinder block to realize sealing between the working table and the lower cylinder block; the upper cylinder block and the lower cylinder block are connected through the telescopic structure to ensure that the entire forming cylinder is in the hermetic state, so that the component forming quality is ensured while solving the sealing problem, and the cleaning problem can be also solved. Compared with the prior art, sealing is not needed between the working table and the forming cylinder according tothe scheme, so that an external device can be reduced, the manufacturing cost is reduced, powder waste is decreased, wear is avoided, and the maintenance amount and component replacement are reduced.

Description

technical field [0001] The invention relates to the field of additive manufacturing, in particular to a laser sintering molding machine. Background technique [0002] In laser sintering technology, the sealing condition of the molding chamber is very high. Most of the current technologies focus on how to use external conditions to realize the sealing state of the molding chamber, such as setting a vacuum pump outside the molding chamber and using vacuum to achieve sealing; or How to design a better sealing part or material to realize the sealing between the workbench and the forming cylinder wall, but the above-mentioned existing technologies cannot achieve a relatively ideal sealing effect, and some of them are even worse due to wear and tear. worsening, leading to a series of maintenance problems due to the need for frequent replacement of seals, and more importantly, resulting in unsatisfactory quality of molded parts; in addition, these current technologies cannot solve ...
