ABSTRACT:
A rapid prototyping process and apparatus by which prototype components can be fabricated for conceptual evaluations. The rapid prototyping process entails the steps of forming a prototype within a process chamber that generates the prototype on a platform of a build chamber through sequentially depositing a layer of material on the platform, fusing the layer of material together, and then lowering the platform so as to allow depositing of a subsequent layer of material on the platform. In this manner, the depositing, fusing and lowering steps are repeated until the desired prototype is obtained. Thereafter, the build chamber, housing the prototype, is detached from the process chamber, and the prototype is cooled while remaining within the build chamber. The prototype is preferably cooled within the build chamber using a nonreactive cooling medium that is caused to flow around the prototype. The build chamber is specially adapted to be used as a cooling chamber that can be readily attached and detached from the process chamber, such that exposure of the prototype to a reactive atmosphere is avoided or at least minimized.
