Abstract

A rapid prototyping process is provided by which prototype components can be fabricated that are suitable for conceptual evaluations. The rapid prototyping process of this invention is more efficient than comparable prior art processes, in that the previous requirement to completely process a prototype article within a single process chamber is eliminated, such that different process steps can be conducted simultaneously on different articles within a single process system. The process entails the steps of forming a prototype within a process chamber that generates the prototype through successively depositing and sintering individual layers of a powder material that fuses together so as to form the prototype. The prototype is then removed from the process chamber and cooled within a separate cooling chamber through which a nonoxidizing cooling medium flows.
