Abstract

The polymeric composition of this invention can be used as a temporary support material in the additive manufacturing of three dimensional articles without compromising the quality of the ultimate product, reducing printing speed, increasing cost, increasing the incidence of printer jamming, or requiring printers of increased complexity. This invention more specifically discloses a polymeric composition which is particularly useful as a temporary support material for utilization in three-dimensional printing, said polymeric composition being comprised of a first polymeric component which is suitable for use as a modeling material and a second polymeric component which is immiscible with the first polymeric component, wherein the polymeric composition has a continuous phase, wherein the continuous phase is comprised of the second polymeric component, and wherein the polymeric composition has a Shore A hardness of at least 80.

Description

[0001] This application claims the benefit of U.S. Provisional Patent Application Ser. No. 62 / 047,723, filed on Sep. 9, 2014. The teachings of U.S. Provisional Patent Application Ser. No. 62 / 047,723 are incorporated herein by reference in their entirety.BACKGROUND OF THE INVENTION

[0002] By definition, “rapid prototyping” is a group of techniques that can be used to quickly fabricate a scale model of a physical part or assembly using 3-dimensional computer aided design (CAD) data. In rapid prototyping, construction of the part or assembly is usually done in an additive, layer-by-layer fashion. Those techniques that involve fabricating parts or assemblies in an additive or layer-by-layer fashion are termed “additive manufacturing” (AM), as opposed to traditional manufacturing methods which are mostly reductive in nature. Additive manufacturing is commonly referred to by the general public as “3D printing”.

[0003] According to ASTM Committee F42 on Additive Manufacturing Technologies, ther...
