Do you consider Rapid Prototyping as Additive Manufacturing?
Rapid Prototyping is definitely additive manufacturing but it was actually just the beginning of this technology:
initially there was no concern on the statistical material properties. Rapid prototyping was being used for manufacturing of sophisticated moulds for castings or for non-critical non-loaded parts to fit into prototype designs. For serial parts production and also going from non-loaded to critical loaded parts, much more stringent requirements for material properties and manufacturing process stability will have to be fulfilled.
