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 about 10 to 30 percent by weight of an oligomeric curable material; about 50 to 75 percent by weight of at least one diluent; and about 3 to 15 percent by weight of a reactive component. Moreover, in some cases, the build material is free or substantially free of a non-reactive wax component.

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, the build material comprising an oligomeric curable material, a reactive component that is present in the build material as crystalline regions, 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 build material when cured exhibits a tensile modulus of 2250-3150 MPa and a tensile strength of 46-76 MPa when measured according to ASTM D 638.
