Methods of producing three-dimensional objects from materials having multiple mechanisms of hardening
First Claim
1. A method of forming a three-dimensional object, comprising:
- (a) providing a carrier and an optically transparent member having a build surface, said carrier and said build surface defining a build region therebetween;
(b) filling said build region with a polymerizable liquid, said polymerizable liquid comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from said first component;
(c) irradiating said build region with light through said optically transparent member to form a solid polymer scaffold from said first component and also advancing said carrier away from said build surface to form a three-dimensional intermediate having the same shape as, or a shape to be imparted to, said three-dimensional object and containing said second solidifiable component carried in said scaffold in unsolidified and/or uncured form; and
(d) subsequent to said irradiating step, heating, microwave irradiating, or both heating and microwave irradiating, said second solidifiable component in said three-dimensional intermediate to form said three-dimensional object.

Abstract
A method of forming a three-dimensional object is carried out by: (a) providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween; (b) filling the build region with a polymerizable liquid, the polymerizable liquid including a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from the first component; (c) irradiating the build region with light through the optically transparent member to form a solid polymer scaffold from the first component and also advancing the carrier away from the build surface to form a three-dimensional intermediate having the same shape as, or a shape to be imparted to, the three-dimensional object, and containing the second solidifiable component carried in the scaffold in unsolidified and/or uncured form; and (d) concurrently with or subsequent to the irradiating step, solidifying and/or curing the second solidifiable component in the three-dimensional intermediate to form the three-dimensional object.

(a) providing a carrier and an optically transparent member having a build surface, said carrier and said build surface defining a build region therebetween; (b) filling said build region with a polymerizable liquid, said polymerizable liquid comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from said first component; (c) irradiating said build region with light through said optically transparent member to form a solid polymer scaffold from said first component and also advancing said carrier away from said build surface to form a three-dimensional intermediate having the same shape as, or a shape to be imparted to, said three-dimensional object and containing said second solidifiable component carried in said scaffold in unsolidified and/or uncured form; and (d) subsequent to said irradiating step, heating, microwave irradiating, or both heating and microwave irradiating, said second solidifiable component in said three-dimensional intermediate under conditions in which said solid polymer scaffold degrades and forms a constituent necessary for the polymerization of said second component, to form said three-dimensional object. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
