Method and Apparatus for Three-dimensional Fabrication

Content Provider	The Lens
Abstract	A method of forming a three-dimensional object, is carried out by (a) providing a carrier and a build plate, the build plate comprising a semipermeable member, the semipermeable member comprising a build surface with the build surface and the carrier defining a build region therebetween, and with the build surface in fluid communication by way of the semipermeable member with a source of polymerization inhibitor; (b) filling the build region with a polymerizable liquid, the polymerizable liquid contacting the build surface, (c) irradiating the build region through the build plate to produce a solid polymerized region in the build region, while forming or maintaining a liquid film release layer comprised of the polymerizable liquid formed between the solid polymerized region and the build surface, wherein the polymerization of which liquid film is inhibited by the polymerization inhibitor; and (d) advancing the carrier with the polymerized region adhered thereto away from the build surface on the build plate to create a subsequent build region between the polymerized region and the build surface while concurrently filling the subsequent build region with polymerizable liquid as in step (b). Apparatus for carrying out the method is also described.

Claim	A method of forming a three-dimensional object, comprising the steps of: (a) providing a carrier and a build plate, said build plate comprising a semipermeable member, said semipermeable member comprising a build surface with said build surface and said carrier defining a build region therebetween, and with said build surface in fluid communication by way of the semipermeable member with a source of polymerization inhibitor; (b) filling said build region with a polymerizable liquid, said polymerizable liquid contacting said build surface, (c) irradiating said build region through said build plate to produce a solid polymerized region in said build region, while forming or maintaining a liquid film release layer comprised of said polymerizable liquid formed between said solid polymerized region and said build surface, wherein the polymerization of which liquid film is inhibited by said polymerization inhibitor; and (d) advancing said carrier with said polymerized region adhered thereto away from said build surface on said build plate to create a subsequent build region between said polymerized region and said build surface while concurrently filling said subsequent build region with polymerizable liquid as in step (b), wherein said build plate is substantially fixed or stationary.
