'Solid Freeform Fabrication of Metal Components Using Traditional PIM Processing Routes'

摘要

For the direct production of metal components for functional application and testing, the MJS (Multiphase Jet Solidification) process is used. The MJS process uses PIM style feedstock systems (e.g. stainless steel, tool steel and Ti) that are extruded through an X-Y-Z translatable nozzle. On the basis of a 3D CAD descripting, the parts are formed layer by layer, eliminating the need for complex and costly tooling. As in powder injection molding, after a part is formed by MJS, the binder phase is removed and the remaining powder compact is sintered to final density. This paper presents the MJS technique and processing routes, and outlines a variety of potential applications.
