This research addresses Three Dimensional Printing, a process for the manufacture of tooling and functional prototype parts directly from computer models. The process offers the critical advantages of rapid part turnaround and minimal investment in tooling. Three Dimensional Printing functions by the deposition of powdered material in layers and the selective binding of the powder by "ink-jet" printing of a binder material. Following the sequential application of layers, the unbound powder is removed, resulting in a complex three dimensional part. The process may be applied to the production of metal, ceramic, and metal/ceramic composite parts. Initially, the focus will be on the manufacture of ceramic parts and will be applied to the rapid fabrication of molds for metal casting and the rapid fabrication of preforms for metal matrix composites.

本研究涉及三维打印， 模具和功能原型的制造过程 直接从电脑模型中提取零件 该过程提供了 快速零件周转的关键优势， 投资工具。 三维打印功能 粉末材料的分层沉积和选择性的 通过粘合剂材料的“喷墨”印刷来粘合粉末。 在顺序应用层之后， 去除粉末，得到复杂的三维部件。 该方法可应用于金属、陶瓷 和金属/陶瓷复合部件。 最初，重点将是 陶瓷零件的制造，并将应用于 金属铸造用模具的快速制造和快速成形 用于金属基复合材料的预成型件的制造。
