发明名称 Process for producing direct tooling mold and method for using the same
摘要 The present invention relates to a method for making a prototype by providing at least one polymeric board material having a glass transition temperature less than the molten temperature of a thermoplastic molding material and removing at least a portion of the polymeric board material to form, according to a computer-aided design, a reverse image of a desired article to be molded. Selected molten polymeric molding material is injected into the resulting mold to produce the desired prototype.
