3D printing or additive manufacturing is the construction of a three-dimensional object from a CAD model or a digital 3D model. It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, with the material being added together, typically layer by layer.
The applications and use cases of 3D Printing vary across industries, but mainly include tooling aids, visual and functional prototypes — and even end-use parts.
