Abstract
Polymerizable liquids are described herein which, in some embodiments, can produce 3D printed articles of high resolution and desirable mechanical properties. In one aspect, a polymerizable liquid comprises an acrylate component, a polymeric additive, and a monomeric curing agent, wherein the acrylate component and monomeric curing agent are copolymerizable upon exposure to light. In being copolymerizable, the acrylate component and monomeric curing agent can form a copolymer. As described father herein, the monomeric curing agent can enable further reaction of the copolymer with one or more crosslinking species to link the copolymer with one more polymeric networks.
Claims18
A polymerizable liquid comprising:
- an acrylate component;
- a crosslinking component;
- and
- a monomeric curing agent,
- wherein the acrylate component and the monomeric curing agent are copolymerizable upon exposure to light;
- and
- wherein the crosslinking component is coated on particles.
A method of printing a three-dimensional article comprising:
- providing a polymerizable liquid comprising an acrylate component, a polymeric additive, a crosslinking component, and a monomeric curing agent;
- irradiating the polymerizable liquid with light to form the article, the article comprising a polymeric composite material including the polymeric additive and a copolymer comprising the acrylate component and the monomeric curing agent;
- and
- crosslinking the crosslinking component with the copolymer comprising the acrylate component and the monomeric curing agent,
- wherein the crosslinking component is coated on particles.
