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.

[0002] The present invention concerns methods and apparatus for the fabrication of solid three-dimensional objects from liquid materials.BACKGROUND OF THE INVENTION

[0003] In conventional additive or three-dimensional fabrication techniques, construction of a three-dimensional object is performed in a step-wise or layer-by-layer manner. In particular, layer formation is performed through solidification of photo curable resin under the action of visible or UV light irradiation. Two techniques are known: one in which new layers are formed at the top surface of the growing...
