3D PRINTER AND PRINTING SYSTEM

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 having the top surface open, having the bottom surface formed as a film layer including an upper film layer, and storing a photocurable material therein; a light source unit including at least one light emitting diode, disposed below the storage unit, and emitting light toward the photocurable material; and a switching unit including an LCD panel disposed between the light source unit and the storage unit, for switching each pixel included in the LCD on and off and selectively transmitting the 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.
