Build material and applications thereof

摘要

In one aspect, build materials operable for use in 3D printing systems are described herein. In some embodiments, a build material comprises an oligomeric curable material, a reactive component that is solid at 25° C., and at least one diluent, wherein the reactive component comprises at least one chemical moiety that is polymerizable with a chemical moiety contained in the oligomeric curable material and/or the at least one diluent.

1. A method of printing a three dimensional article comprising:
selectively depositing layers of a fluid build material to form the three dimensional article on a substrate,wherein the build material comprises:
an oligomeric curable material; a reactive component; a non-reactive component comprising one or more urethane waxes; and at least one diluent,wherein the reactive component comprises at least one chemical moiety that is polymerizable with a chemical moiety contained in the oligomeric curable material and/or the at least one diluent and wherein the reactive component is present in the build material as crystalline regions.
