Abstract: The present invention relates to a method and apparatus for 3D printing using a photopolymer. An aspect of the present invention is to provide a method and apparatus for 3D printing using a photopolymer, which can shorten time taken in forming a sculpture body. To this end, the method of 3D printing using a photopolymer, which forms a sculpture body using a liquid photopolymer resin filled in a resin tank having a transparent bottom plate, wherein the sculpture body is stacked to form layers on a bed, comprises lifting up the bed with respect to the bottom plate of the resin tank within an at least partial thickness range of a unit shaping layer and forming the at least partial thickness range of the unit shaping layer during a layer image light for the unit shaping layer is being emitted.

Abstract: The present invention relates to a 3D printer with an exposure system for a large-scale screen.

Abstract: Disclosed is a 3D printer including a resin container which is filled with a photocurable liquid resin; a circulating pipe which forms a circulating channel through which the liquid resin is drained out of the resin container and then returned to the resin container; a circulating pump which circulates the liquid resin in the circulating channel; a heating unit which heats the liquid resin; and a filter which filters out impurities from the liquid resin in the circulating channel. According to the present invention, there is provided a 3D printer, in which cured floaters are easily removed by increasing fluidity of a liquid resin, a printed object is improved in quality, and the liquid resin is automatically replenished.
