Abstract:
According to various embodiments, a system for forming a ceramic part includes a chamber having a first closed end and a second end defining an opening. The platform is disposed within the chamber and adapted to move vertically in a z-direction between the first closed end and the second end. An applicator is adapted to move laterally in an x-y direction. The applicator includes a beveled edge. A light source is positioned in line with the second end of the chamber. A digital micro-mirror device is positioned between the light source and the second end of the chamber. The shutter is movable between a first open position and a second open position. A first image is projected when the digital micro-mirror device is in the first open position and a second image, different than the first image is projected when the digital micro-mirror device is in the second open position.
