LCD 3D An LCD based high speed 3D printer

摘要

The present invention relates to an LCD-based high-speed 3D printer, and more particularly, a resin storage tank in which a photocurable liquid resin is stored and a transparent bottom surface, a builder with attached output and movable up and down, and an LCD panel provided in close contact with the lower part of the resin storage tank And in configuring the 3D printer of the DLP method comprising a backlight light source provided under the LCD panel, the air injection and exhaust structure through the air flow pipe between the resin storage tank and the close contact surface of the LCD panel in close contact with the resin storage tank lower portion. Introduced, in the process of raising and lowering the builder according to the 3D printing operation, the vertical fluctuation of the LCD panel caused by the vacuum adsorption force between the bottom surface of the resin storage tank provided in close contact with each other and the LCD panel is prevented, so that the LCD panel in the printing process is reduced. It relates to an LCD-based high-speed 3D printer capable of effectively high-speed printing of large-area prints by effectively preventing deformation and breakage, while also effectively separating the printed material under the builder and the bottom of the resin storage tank.
