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, and a composite resin comprising a curable carrier and polymeric particles dispersed in the curable carrier. The polymerizable liquid also comprises a photoinitiator component.
Claims20
A polymerizable liquid comprising:
- an acrylate component;
- a composite resin comprising a curable carrier and polymeric particles dispersed in the curable carrier;
- and
- a photoinitiator component,
- wherein the acrylate component is present in an amount of 30-70 wt. % based on a total weight of the polymerizable liquid.
