... networking at conferences.) The earliest known use of the term 3-D printing as applied to AM was in an article by Wohlers in 1988 that reviewed the then-new stereolithography machine recently commercialized by Hull ( Ref 1 ). The concept of printing an object was in use at least as early as 1984, when Hull...
