Method and apparatus for three-dimensional fabrication with feed through carrier

摘要

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, 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; (e) wherein the carrier has at least one channel formed therein, and the filling step is carried out by passing or forcing the polymerizable liquid into the build region through the at least one channel. Apparatus for carrying out the method is also described.

1. 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 between said solid polymerized region and said build surface, 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; (e) continuing and/or repeating steps (b) through (e) to produce a subsequent polymerized region adhered to a previous polymerized region until the continued or repeated deposition of polymerized regions adhered to one another forms said three-dimensional object; (f) wherein said carrier has at least one channel formed therein, and said filling step is carried out by passing or forcing said polymerizable liquid into said build region through said at least one channel and through said object.
