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 23):
A method of  claim 1 , comprising the steps of:\n providing a carrier and an optically transparent member having a build surface, said carrier and said build surface defining a build region therebetween; filling said build region with a polymerizable liquid; irradiating said build region through said optically transparent member to form a solid polymer from said polymerizable liquid and advancing said carrier away from said build surface to form said three-dimensional object from said solid polymer, while also concurrently: (i) continuously maintaining a dead zone of polymerizable liquid in contact with said build surface, and (ii) continuously maintaining a gradient of polymerization zone between said dead zone and said solid polymer and in contact with each thereof, said gradient of polymerization zone comprising said polymerizable liquid in partially cured form; 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.
