Abstract: In a method of producing a 3D part using an electrophotography-based additive manufacturing system, a plurality of layers of a powder-based material are developed using at least one electrophotography (EP) engine. The developed layers are transferred to a transfer medium. The layers on the transfer medium are dried by heating the layers without fully fusing the powder-based material to itself using a dryer. This reduces a water content of the layers. The dried layers are heated on the transfer medium to at least a fusion temperature, at which the power-based material fuses together, using a pre-transfusion heater. The dried layers are then transfused together on a build platform using a transfusion assembly to build the part in a layer-by-layer manner.
