TRANSPARENT WINDOW HAVING SUPER-HYDROPHOBIC OR SUPER-OLEOPHOBIC PROPERTIES FOR 3D PRINTER, AND 3D PRINTER HAVING SAME

摘要

According to an embodiment of the present invention, the present invention relates to a printer for generating a three-dimensional printout by projecting light onto a photocurable resin accommodated in a resin tank to partially cure the same. The light is projected onto the photocurable resin through a transparent window provided in a part of the resin tank, and the transparent window is formed to be super-hydrophobic or super-oleophobic so as to be easily separated from the printout. Therefore, final separation of the transparent window of the resin tank and the three-dimensional printout can be easily realized even when a so-called dead zone, in which an uncured resin forms a layer regardless of irradiation of light due to interference with photocuring by oxygen, is not formed. Also, the printout is easily separated by using the super-hydrophobic or super-oleophobic properties even without a separate process, such as tilting or sliding. Furthermore, the printer of the present invention is free of the thickness of the resin tank not to be required to be manufactured in an excessively thin thickness, and does not require a dead zone, thereby having uniform printing thickness.;COPYRIGHT KIPO 2019
