21 - Do the 7 Families of Additive Manufacturing Technologies Still Make Sense?

AM Radio

Additive manufacturing contains more than 3D printing, but even this term carries multiple meanings. 3D printing might mean extruding plastic, or depositing binder into metal, or melting material with lasers, or any number of other things. In this episode, Stephanie Hendrixson and Peter Zelinski try to stump each other with some unusual 3D printing processes and consider whether the "Seven Families of Additive Manufacturing Technologies" are still relevant 10 years after they were created.

This episode is brought to you by the Additive Manufacturing Conference at IMTS.
