#3D Printing
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model.[1] The term “3D printing” can refer to a variety of processes in which material is deposited, joined or solidified under computer control to create a three-dimensional object,[2] with material being added together (such as plastics, liquids or powder grains being fused together), typically layer by layer.
