Why “Additive Manufacturing” and not “3D printing” ?
We think term 3D printing can easily mislead to the assumption that it is
only one technology that can process any material.
According to the ASTMF2792-12a norm, Additive Manufacturing (AM) describes seven groups of different technologies which enable to create three-dimensional objects straight from virtual models usually created by using computer aided design data (3D CAD).
Parts can be created from different materials. Polymers, metals, ceramics and even
living cells can be processed. Usually,it is only one material being processed at a time but there are some multi-material machines available.
ASTM F2792-12a categorize the technologies in seven technology groups:
