Abstract
A prepolymer with multiple functional groups is disclosed. The embodiments of the prepolymer may have the compound of formula X: A polymerizable liquid comprising such prepolymer that can be used for producing three-dimensional objects by methods of additive manufacturing and the method using such polymerizable liquid to form three-dimensional objects is also described.
Claims20
A prepolymer compound of formula X:
- wherein:
- Z is a blocking group;
- R1, R2, and A are each independently selected a hydrocarbyl group;
- R′ is NH or O;
- and
- Y comprises an amino alcohol or diamine moiety.
A polymerizable liquid used for producing three-dimensional objects by methods of additive manufacturing, said polymerizable liquid comprising:
- a prepolymer compound;
- and
- a photoinitiator.
A method of forming a three-dimensional object, comprising:
- providing a printing region defined by a forming platform and a resin reservoir having a forming surface;
- filling said printing region with a polymerizable liquid, said polymerizable liquid including a prepolymer compound and a photoinitiator;
- exposing said printing region filled with said polymerizable liquid to energy to form a solid printing intermediate having substantially the same shape as said three-dimensional object;
- providing energy to said solid printing intermediate to form said three-dimensional object.
