Title: Additive manufacturing with integrated microliter resin delivery

Abstract

An additive manufacturing system utilizing an oxygen-permeable membrane to facilitate low-volume printing and high-speed resin change in a stereolithography-based 3D printer. The membrane is used to constrain the fluid surface at the focal plane of the stereolithography printer and a carrier fluid is used to hold the fluid against the membrane. The small amount of resin is quickly switched using integrated microfluidic channels.
