What is 3D Printing? 3D printing is an innovative type of manufacturing that utilizes a computer-aided design program (CAD), as well as various types of thermoplastic or filament, to create a three dimensional object from a digital file. This process is often referred to as a type of "additive" manufacturing, being that the completed object is created through the formation of individual layers, as opposed to standard manufacturing, which cuts out and removes the excess material in order to form the completed object.
