Abstract
Provided herein according to some embodiments is polymerizable liquid useful for the production of a three-dimensional object by additive manufacturing, said polymerizable liquid comprising a mixture of: (a) at least one photopolymerizable component; (b) a photoinitiator, (c) at least one heat polymerizable component; and (d) heat expandable microspheres. A method of making a three-dimensional object from such a polymerizable liquid by additive manufacturing and objects so produced are also provided.
Claims18
A method of making a three-dimensional object, comprising:
- (a) producing an intermediate object from a dual cure resin by additive manufacturing, wherein the dual cure resin comprises heat expandable microspheres;
- (b) optionally cleaning said intermediate object;
- and then
- (c) further curing said intermediate object by contacting the intermediate object with water and heating and/or microwave irradiating said intermediate object for a time and at a temperature sufficient to expand said microspheres.
