Description

SLS3D prints integrative equipment of aftertreatment Technical Field The utility model relates to additive manufacturing technology, in particular to SLS3D printing and post-processing integrated equipment. Background The SLS3D post-printing treatment technology is used for cleaning the printed part from the state of being wrapped by loose powder, and the working procedures to be completed include powder cleaning, powder sieving and powder mixing. The parts are also subjected to a high-pressure air flow to perform a surface finish treatment and the like. Defects and deficiencies of the prior art: In the prior art, besides the manual working procedures, most of post-treatment equipment on the market has single function, and the powder cleaning, powder sieving, powder mixing and surface finish treatment are all completed by a single equipment, so that the field space of a customer can be greatly occupied, and for the customer with limited field, only post-treatment can be carried out externally, thereby being unfavorable for quick completion. In order to overcome the defects, the invention changes the current situation, integrates the processes of powder cleaning, powder sieving, powder mixing and surface finish, compresses the space of equipment and ensures that the equipment can complete the maximum function with the minimum volume.
