    摘要： A rapid prototyping system has a liquifier carried by a extrusion head. The liquifier is formed of a single piece of thin-wall tubing preferably made of metal, encased in a heating block. The thin-wall tube has a inlet end for receiving a filament of molding material and an outlet end for delivering the material in liquid form. A first section of the tube adjacent the inlet end functions as the entrance or cap zone. This first section of the tube is exterior to the heating block. The tube has a second section which passes through the heating block forming a heating zone. A nozzle can be formed by swaging the outlet end of the tube to a nozzle geometry, or, a nozzle may be brazed or welded to the outlet end of the tube. The heating block preferably contains a heating element in heat exchange relation to the second section of the tube to heat the filament to a temperature just above its solidification temperature. The extrusion head may alternatively carry two liquifiers that share a common nozzle, for receiving and dispensing two different materials.

    摘要： A filament cassette and a filament loading assembly supply modeling filament to a liquifier in a three-dimensional deposition modeling machine. Two or more cassettes containing spooled filament are inserted into the machine. A strand of filament from a first one of the cassettes is fed to the liquifier for extrusion. Without operator intervention, the filament strand from the first cassette is withdrawn from the liquifier, and a filament strand from a second one of the cassettes is fed to the liquifier. The switching of filament feed sources is triggered by an event, such as an identification that the filament from the first cassette has reached a predetermined minimum length. In this manner, a used primary filament cassette is automatically replaced with a standby filament cassette, so that the machine need not experience downtime waiting for an operator to change the cassettes.

    摘要： 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.
