摘要： The present invention relates to a 3D printer and a printing system. The present invention may include: a storage unit formed in a hexahedral shape and having an open top and a bottom surface formed of a film layer comprising an upper film layer, the storage unit storing a photocurable material therein; a light source unit comprising at least one light emitting diode, the light source unit being disposed below the storage unit and radiating light toward the photocurable material; and a switching unit comprising an LCD panel disposed between the light source unit and the storage unit, the switching unit opening and closing each pixel included in the LCD panel to selectively pass light emitted from the light source unit toward the photocurable material. Accordingly, light emitted from below the storage unit can be emitted toward the photocurable material without being distorted.
