Abstract
An apparatus and process for forming a predetermined three-dimensional (3D) object, in particular to an apparatus and method for making of a predetermined 3D object including an outer finished show surface without the use of post processing steps, and selectively printing three-dimension features onto another surface without compromising the integrity of the outer finished surface quality. A build platform of the apparatus includes a smooth surface to disperse deposited materials into a highly uniform base layer with exceptional surface quality on the interface between the deposited material and the build platform. The apparatus and process have the ability to produce an exceptionally smooth surface capable of achieving automotive standards for exterior components without the use of post-processing.
