- Together with the well established “Subtractive Manufacturing, such
as milling or turning, and the “Formative Manufacturing, such as
casting or forging, Additive Manufacturing provides the third
supporting pillar of the entire manufacturing technology.
- When the first approaches to Additive Manufacturing entered the
market in 1987, it was called “Rapid Prototyping or Generative
Manufacturing.
- Both terms are still in use and in the past years many different names
have been presented and frequently more are added.
- Although each of the names is perfect from the special viewpoint of
its creator, many of them cause confusion. Often, this is one reason
why newcomers to the industry in particular sometimes feel lost in
the field of AM.

1983 Charles Hull invents
HullStereolithography (SLA) Charles ‘Chuck’
technologywas the first to develop a for
creating solid objects from a CAD/CAM file, inventing the
process he termed ‘stereolithography in 1983. SLA works
by curing and solidifying successive layers of liquid
photopolymer resin using an ultraviolet laser. The field that
came to be known variously as 'additive manufacturing',
'rapid prototyping' and '3D printing' was born.
History of 3D Printing:
The earliest 3D printing technologies first became visible in
the late 1980s, at which time they were called Rapid
Prototyping (RP) technologies. This is because the processes
were originally conceived as a fast and more cost-effective
method for creating prototypes for product development
within industry.

- As Additive Manufacturing (AM) is a comparably young technology,
there were almost no efforts for standardization for many years other
than some preliminary work in Germany in the early 1990s.
- In 2007, a special recommendation dedicated to Rapid Prototyping
/VDI3404/ was created under the supervision of the German Society of
Mechanical Engineers, VDI. It was published in autumn of 2008.
- As of 2009, the American Society of Mechanical Engineers (ASME) in
cooperation with the American Society for Testing and Materials (ASTM)
started the development of their own standardization procedures. In
autumn 2009, the committee F42 on Additive Manufacturing
(subcommittee F42.91 on Terminology) issued F2792-09e1 /F2792/, also
called Standard Terminology for Additive Manufacturing Technologies.
- Among other definitions, the name Additive Manufacturing was
defined by this committee.

Concept
Additive Manufacturing” (AM) is a layer-based automated fabrication
process for making scaled 3-dimensional physical objects directly from 3D-
CAD data without using part-depending tools. It was originally called “3D
Printing and is still frequently called that.
