Inclined pulling assembly for 3D printing device

Abstract

The utility model discloses an inclined pulling assembly for a 3D printing device. The inclined pulling assembly comprises a mounting bracket and a hollow support frame movably connected with the mounting bracket through a connecting piece, wherein a resin frame used for accommodating a printing solution is mounted on the support frame; the bottom of the resin frame is a transparent bottom plate; a pull rod is further arranged at the bottom of the side edge, opposite to the connecting piece, of the support frame, and is connected with a driving motor; the support frame is enabled to rotate along the connecting piece through the ascending and descending of the pull rod. By adopting the inclined pulling assembly, a curing layer is completely separated from the bottom of the resin frame by pulling downwards on one side slowly, translation for increasing the plane area of the resin frame is not required, friction generated by translation is avoided, the service life of a thin film on the transparent bottom plate of the resin frame is greatly prolonged, and generally, one resin frame can be used for printing for 400,000-500,000 times.

Description

technical field [0001] The invention relates to a slanted component for a 3D printing device, which belongs to the technical field of printing equipment. Background technique [0002] A 3D printing device, also known as a three-dimensional printer, is a machine that uses cumulative manufacturing technology (that is, rapid prototyping technology). Its principle is to put data and raw materials into a 3D printer, and the machine builds products layer by layer according to the program. At present, the most common 3D printing device is SLA three-dimensional printing (also known as stereolithography, light modeling) using surface forming technology. The specific working principle is: the liquid tank is filled with liquid photocurable resin, It will solidify in the set area. When the molding starts, the working platform is on the liquid surface, and the distance between its lower surface and the upper surface of the transparent bottom plate at the bottom of the liquid tank is the ...

AI Technical Summary

Problems solved by technology

When the 3D printing device with this structure is solidified, because the tension between the solidified layer and the transparent bottom plate at the bottom of the liquid tank is very high, the printing platform cannot be pulled up vertically, and then two planes with a certain height difference are required to translate, resulting in a large lateral space area of ​​the machine. Large, it takes up space and wastes liquid photocurable resin, and the repeated translation makes the film on the transparent bottom plate of the irradiation platform easily damaged due to friction, and the life is short. Generally, only 8000-10000 layers can be printed and must be replaced. It not only increases the replacement process but also greatly increases the printing cost
