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.
Claims18
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 comprises a mixture of acrylate monomer and acrylate oligomer and the acrylate monomer is present in an amount of 40-95 wt. % based on total weight of the acrylate component.
