3D Printing is a process of attempting to make
a physical object from a digital three-dimensional model, generally by laying
down several subsequent thin layers of a material. It involves bringing of a digital
object i.e. CAD representation of an object to its physical form by adding
layer by layer of materials. There are various techniques for performing 3D
printing. 3D Printing helps to bring
with it two important advancements: the handling of objects in their digital
format and the production of new shapes by adding material.
The most fundamental and distinguishing
concept behind 3D printing is that it's a method of additive manufacturing. And
this really is the key, since 3D printing is a fundamentally different
manufacturing process based on innovative technology that creates parts in
layers additively. This is radically different from all other conventional
manufacturing methods that already exist.
