Abstract:
A build plate for a three-dimensional printer includes: a rigid, optically transparent, gas-impermeable planar base having an upper surface and a lower surface; and a flexible, optically transparent, gas-permeable sheet having an upper and lower surface, the sheet upper surface comprising a build surface for forming a three-dimensional object, the sheet lower surface positioned on the base upper surface. The build plate includes a gas flow enhancing feature configured to increase gas flow to the build surface.
