3d printer and separation method of 3d printed body

Abstract

The present disclosure relates to a 3D printer and a method for separating a 3D printed object. The 3D printer includes a printed object carrying platform, and the 3D printer further includes: a temperature processing module, which is used to separate the printed object carrying platform from the printed object. The printed body on the body carrying platform is subjected to temperature treatment. Through the above technical solution, without changing the structure of the printing body carrying platform as in the prior art, it can effectively ensure the successful separation of the printing body, thereby ensuring the flatness of the printing body carrying platform, so that the 3D printer can also print Models that require flat surfaces improve the applicability of 3D printers. At the same time, it can reduce the work difficulty of technicians when separating the printed body, save manpower and material resources, and can improve the success rate of safe separation of 3D printed bodies, effectively ensuring the quality of printed body separation.

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
