Abstract: A polymeric material used for 3D printing is preheated, at a first zone in a 3D printer, to a temperature in excess of its glass transition temperature prior to being melted, at a second zone, for incorporation into a build object. This enables the polymer to be processed more rapidly than in the prior art.
