Abstract
The present invention is a modeling technique wherein a three-dimensional model and its support structure are built by fused deposition modeling, using a thermoplastic blended material containing a polyphenylsulfone (PPSF) polymer and a polycarbonate (PC) polymer to form the model. The PPSF/PC blend exhibits good chemical resistance, thermal stability, and resists build-up in the nozzle of a three-dimensional modeling apparatus. Removal of the support structure from a completed model is facilitated by operating on the material while it is hot.
