Problems solved by technology

[0005] However, in the case where the 3D printer includes a projector, in order to print a large output, a large projector is formed on the 3D printer, so the height of the 3D printer increases, thereby increasing the cost.

Abstract

The present invention relates to a 3D printer and a printing system. The 3D printer comprises: an accommodating unit which is in the shape of a cube with an open top, has a bottom surface formed by afilm layer including an upper film layer, and accommodates a phorocurable material therein; a light source unit which comprises at least one light-emitting diode, is disposed at a lower part of the accommodating unit and irradiates light toward the photocurable material; and a switching part comprising an LCD panel which is disposed between the light source unit and the accommodating unit. The light irradiated from the light source unit selectively passes the photocurable material by opening and closing each of pixels included in the LCD panel, so that the light irradiated from the lower partof the accommodating unit can be irradiated to the photocurable material without being deformed.

Description

technical field [0001] The present invention relates to a three-dimensional printer and a printing system, and more specifically, to a three-dimensional printer and a printing system including a storage portion formed with a film layer. Background technique [0002] Three-dimensional printer technology manufactures complex structures in a short time by layering outputs corresponding to drawings formed using computer-aided design (CAD, Computer Aided Design) without cutting. Recently, the above-mentioned technologies have been widely used in industries such as medical care, automobiles, ships, shoes, etc. beyond the marketed products. [0003] Among the representative technologies in 3D printing technology, stereolithography equipment (SLA, Stereo Lithography Apparatus) that uses photocurable materials to irradiate light or laser to harden the material and then manufactures structures, and uses plastic or metal powder materials to irradiate laser light And the selective lase...
