Apparatus and related method for forming a substantially flat stereolithographic working surface

摘要: An apparatus and related method for providing a substantially flat working surface of photocurable resin the formation next layer stereolithographic part. A rigid member is covered by spaced from substance or film, which placed in contact with to form surface. Various embodiments are described including where quartz fused silica plate, bar, vat wall, face CRT, fiber-optic bundle, bottom piston, also film thin teflon mylar an inert liquid, wax, coating trichlorosilane ethoxysilane, oxygen-saturated resin. Embodiments whereby exposed transmitting solidifying radiation through film.
