Abstract:
A method of forming a three-dimensional object by bottom-up three-dimensional fabrication by irradiating a polymerizable liquid to produce the three-dimensional object, is described. In the method: (i) a Lewis acid or an oxidizable tin salt (e.g., stannous octoate) is included in said polymerizable liquid in an amount effective to accelerate the formation of said three-dimensional object during said fabrication; and/or (ii) the three-dimensional object is irradiated after forming to further polymerize unpolymerized material remaining in the three-dimensional object.

Claim (Index 17):
A method of  claim 1 , comprising the steps of:\n (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, 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) 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; optionally but preferably with said polymerizable liquid further comprising a Lewis acid or an oxidizable tin salt accelerant of the forming of said three-dimensional object and/or with the method further comprising irradiating said three-dimensional object after completion of said advancing step(s) to further polymerize unpolymerized material remaining in the three-dimensional object.
