3D printer and 3D printing body separation method

Abstract

The invention relates to a 3D printer and a 3D printing body separation method. The 3D printer comprises a printing body bearing platform and further comprises a temperature processing module for conducting temperature treatment on the printing body bearing platform and a printing body on the printing body bearing platform. By means of the above technical scheme, successful printing body separation can be effectively guaranteed without changing on a printing body bearing platform structure in the prior art, accordingly, the flatness of the printing body bearing platform can be guaranteed, the3D printer can print a model with the whole face flatness requirement, and the applicability of the 3D printer is improved. Meanwhile, the work difficulty of printing body separation by technicists can be reduced, manpower and material resources are saved, the safe separation success rate of the 3D printing body can be increased, and the printing body separation quality is effectively guaranteed.

Description

technical field [0001] The present disclosure relates to the field of 3D printing, in particular, to a 3D printer and a method for separating a 3D printed body. Background technique [0002] Photocuring 3D printers are a technology that uses light to excite photosensitive resins for curing. The first layer of printed body at the beginning of printing must be bonded to the printed body carrying platform and maintain a certain bonding strength to accept the printed body of the second layer or above. For the printing success rate, the greater the bonding strength, the better; but for removing the printed body from the printing body carrying platform after printing, the smaller the bonding strength, the better, so there is a contradiction here. [0003] In the prior art, the separation of 3D printed bodies is usually achieved through the following three schemes: [0004] 1. Accurately control the surface roughness of the printing body carrying platform to balance the bonding s...

AI Technical Summary

Problems solved by technology

[0004] 1. Accurately control the surface roughness of the printing body carrying platform to balance the bonding strength between the printing body and the printing body carrying platform, but in actual use, this balance is difficult to grasp, and there are contradictions in the printing of large-area and small-area parts by the printer itself , this solution does not fundamentally solve the problem

[0005] 2. It is possible to punch holes on the printing body carrying platform. After the printing body is printed, use a cylinder to push it out from the air, and then separate the printing body from the printing body carrying platform. However, the printing body carrying platform using this method has holes, so it cannot Print models that require a flat surface

[0006] 3. You can make grooves on the printing body carrying platform, and use something like a comb to shovel the printing body off, but this method cannot print models that require a flat surface
