MATERIAL AND METHOD FOR THREE-DIMENSIONAL MODELING

摘要

A three-dimensional model (26) and its support structure (28) are built by fused deposition modeling techniques, wherein a thermoplastic material containing silicone is used to form the support structure (28) and/or the model (26). The silicone acts as a release agent to facilitate removal of the support structure from the model after its completion. The thermoplastic material containing silicone exhibits good thermal stability, and resists build-up in the nozzle (24) of an extrusion head (12) or jetting head of a three-dimensional modeling apparatus (10).
