What is 3D printing?

3D printing, often known as additive manufacturing, is the complete opposite to the conventional method of making objects. Instead of machining or "subtracting" material to make objects in the same way that sculptors cut away clay, 3D printing adds layer upon layer of material to build an object. Product designers and engineers upload the digital (CAD) document to a 3D printer. www.pick3dprinter.com/3d-prints-stringing/
