The present invention is a method and apparatus for building three-dimensional models by deposition modeling techniques from moisture-sensitive thermoplastics. A feedstock of thermoplastic modeling material is dried to a low moisture content and supplied to a dispensing head of a modeling apparatus. The dry thermoplastic material is heated in a liquifier and deposited in a predetermined pattern so as to build a three-dimensional model.
