Abstract: A method and system for printing a three-dimensional part, which includes rotating a transfer belt with a developed layer, scanning the developed layer on the rotating transfer belt, pressing the developed layer into contact with an intermediate build surface of the three-dimensional part retained on a moveable build platform, scanning the pressed layer on the three-dimensional part, comparing the scanned layers to detect an overlay error, and adjusting a position of the moveable build platform relative to the transfer belt to reduce the overlay error for a subsequent developed layer.

Abstract: A method of printing a part using an additive manufacturing system includes identifying a part or parts to print and orienting a digital representation of the part(s) in a build volume. A digital representation of porous support structures for the part(s) is generated to form a digital representation of a part block of the part(s) to be printed. In the part block, a porosity of the support structure increases as a distance from an outer surface of the part increases within the print volume. The digital representation of the part block, including the part(s) and porous support structures, is sliced for printing.
