3D PRINTING
Additive manufacturing or 3D printing
is a process of making a three-dimensional solid object of virtually
any shape from a digital model. 3D printing is achieved using an additive process, where successive layers of material are laid down in different shapes.
3D printing is considered distinct from traditional machining
techniques, which mostly rely on the removal of material by methods such
as cutting or drilling (subtractive processes).
A materials printer usually performs 3D printing processes using
digital technology. Since the start of the twenty-first century there
has been a large growth in the sales of these machines, and their price
has dropped substantially.
The technology is used in jewelry, footwear, industrial design,
architecture, engineering and construction (AEC), automotive, aerospace,
dental and medical industries, education, geographic information
systems, civil engineering, and many other fields
.
