Materials for additive manufacturing - ScienceDirect

1/1/2017· 1. Additive manufacturing Modern additive manufacturing (AM), also known as 3D Printing, dates to the mid-1980s. The first commercial AM fabrior, the SLA-1 was sold in 1988 by 3D Systems, founded in 1986. According to Bourell , precursor AM processes predate modern AM by about 30 years, with examples of lithographic human-scale manufacturing dating to the mid-1800s.
