3D PRINTING SYSTEM

WIPO Patent Application WO/2022/010333

A1

Provided is a 3D printing system capable of forming an object to be printed while laminating layers one upon another by using photocurable resin, the 3D printing system comprising: a receiving part for receiving photocurable resin; a light engine which is installed at the lower side of the receiving part and provides a light source for forming an object to be printed to the receiving part to cure the photocurable resin; a plate which is installed at the upper side of the receiving part to be able to move up and down, and forms a three-dimensional object to be printed by laminating photocurable resin for each monolayer on the bottom surface thereof while being immersed in the photocurable resin; an elevation member which, after lamination of a monolayer on the plate is completed, moves the plate up to separate the plate from the bottom surface of the receiving part, and moves the plate down again to allow lamination of a subsequent monolayer; and a resin supply member for supplying photocurable resin to the receiving part up to a predetermined level, the resin supply member selectively supplying the photocurable resin to a region, in which printing is performed by the light engine, among the reception space of the receiving part while adjusting a position of supply of the photocurable resin.
