Abstract

See full text

A method and system for printing a three-dimensional part, which includes producing a developed layer of a part material with one or more electrophotography engines of an additive manufacturing system, transferring the developed layer from the one or more electrophotography engines to a transfer assembly of the additive manufacturing system sintering the developed layer at the transfer assembly to produce a sintered contiguous film, cooling the sintered contiguous film down to a transfer temperature, and pressing the cooled sintered contiguous film into contact with an intermediate build surface of the three-dimensional part with a low applied pressure.
