Material issues in melted extrusion manufacturing

摘要

Melted extrusion Manufacturing(MEM) is a process for making three-dimensional objects layer by layer from thermoplastic materials directly from CAD files. The materials employed lead to parts that are sued as not only concept models but also functional prototypes. Based on the introduction to the MEM process and machines, this paper describes the MEM materials requirements, filament making process, avaliable materials performance and the applications in detail.
