Metal-Based Additive Manufacturing
(3D Printing)
Metallurgy and Processing Science
Presented: Wednesday, July 1, 2020
In 2010, the first standard, ASTM F2792-10, additive manufacturing (AM) is defined as:
“The process of joining materials to make objects from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing technologies.”
In accordance to the ASTM F42 Committee on Additive Manufacturing, there are four process categories that is metal-based AM:
- Powder bed fusion (PBF)
a. Selective laser melting (SLM)
b. Electron beam melting (EBM) - Direct energy deposition (DED)
a. Laser vs. e-beam
b. Wire fed vs. powder fed - Binder jetting
a. Infiltration
b. Consolidation - Sheet lamination
a. Ultrasonic additive manufacturing (UAM)
