There are several different methods of 3D printing, but the most widely used is a process known as Fused Deposition Modeling (FDM). FDM printers use a thermoplastic filament, which is heated to its melting point and then extruded, layer by layer, to create a three dimensional object.
With the advent of 3D printing, artists and designers are now able to pull their creations from the virtual world and turn them into physical objects.
Speed is the biggest benefit of FDM printing. Concepts can be altered and reprinted numerous times to achieve the desired object at low cost
