POLYMERIC COMPOSITION FOR USE AS A TEMPORARY SUPPORT MATERIAL IN EXTRUSION BASED ADDITIVE MANUFACTURING

摘要

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.The polymeric composition offers an array of properties which make it highly desirable of use as a temporary support material in three-dimensional printing. The support material of this invention can be used to generate support structures that can be easily removed by simple mechanical means.
