Standard for material extrusion

ASTM International’s additive manufacturing technologies committee has approved a new standard guide for the use of layer-based material extrusion (MEX) processes in additive manufacturing (AM). 

MEX processes are used to fabricate polymer or polymer composite parts by depositing a filament or bead of material from an extrusion head. 

“The new standard will help product designers take advantage of the unique capabilities of material extrusion processes,” said ASTM International member David Rosen. “Designers will learn how to design potentially novel, geometrically complex, high-performance parts.” 

The committee also says that it was looking for people to help evaluate technologies that impact AM usage and applications, such as AM process simulation software, AM pre-processing software, post-processing technologies, and other topics.
