AM from its beginnings
Where manufacturing begins

AM is not a new technology and its birth is traditionally traced back to the 1980s, when Chuck Hull started experimenting stereolithography (SLA), one of vat photopolymerization processes. He filled the US patent 4,575,330  (1984) and founded 3D Systems (1986), still nowadays one of the most innovative growth companies (II).
