3D-Printing is a process of making physical objects from digital models by additive manufacturing. It is a new way to create parts for mechanical designs; it provides the capability for manufacturers to make parts directly from digital files instead of machining the part out of raw material
The 3D printer is the heart of an additive manufacturing machine, which consists of three major components: the printer head, material deposition unit and build platform. The printer head is a high-precision mechanism that applies material to a build surface much like a traditional milling machine.
