OPTICAL THREE-DIMENSIONAL SHAPING DEVICE

摘要

PURPOSE:To provide an inexpensive optical three-dimensional shaping device capable of obtaining a high detailed three-dimensional image within a short shaping time and having a simple structure. CONSTITUTION:A beltlike region where the surface of a liquid is irradiated with light is moved in the right direction along with a moving stage 3 and stopped at the point of time when the center of a lens array 15 passes the right end R of the drawing region of a screen 1. By this movement under the irradiation with light, the figure drawn on the screen 1 is projected on the surface of the liquid and a thin cured part is formed. A shaping head 20 is raised by one slice pitch by the precise feed due to a moving unit 21 and the part cured at this time is bonded to an upper already cured three-dimensional image to be separated from the surface of glass and a new liquid photo-setting resin flows in this gap.
