Title:
3D PRINTING DEVICE AND 3D PRINTING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/223761
Kind Code:
A1
Abstract:
Disclosed in the present invention is a 3D printing device. The device comprises a print bed, a light source, and a controller. A reservoir is disposed at a middle portion of the print bed, a non-stick element is disposed on an inner wall of the reservoir, and a polymerizable liquid is contained inside the reservoir. The device further comprises a base aligned and matched with the reservoir. A driving device is connected to the base, and the light source is joined at the bottom of the base. Since the non-stick element is used as a covering component of the reservoir, after the polymerizable liquid is cured and shaped, a constructed object can be rapidly and efficiently separated from the non-stick element, so as to facilitate further forming and processing operations. In this way, the overall 3D printing process becomes swifter and more efficient, avoiding any damage to products or component structures due to excessive adhesion when removing formed products from the assembly. Thus, the method ensures effective processing of products, as well as stable operation of the assembly and equipment. The present invention further discloses a 3D printing method which uses the 3D printing device.
