Abstract: A method for making a three-dimensional (3D) part with an electrostatographic based additive manufacturing system includes developing a first layer of a powder material using at least one electrostatographic engine, supporting the developed first layer on a transfer medium, adjusting a first layer thermal profile of the developed first layer with a first thermal flux device, adding thermal energy to a part thermal profile that includes a bonding region of previously accumulated layers of the 3D part, transfusing the developed first layer on the bonding region of the previously accumulated layers of the 3D part, and removing thermal energy from the part thermal profile. A transfusion temperature at a start of the transfusing step can be equal to or greater than a transfusion threshold temperature, where the transfusion temperature is an average of the first layer thermal profile and the part thermal profile in the bonding region.

Abstract: A selective-deposition-based additive manufacturing system (10) includes a transfer medium (24) configured to receive the layers (22) from an imaging engine (12), a heater (72) configured to heat the layers (22) on the transfer medium (24), and a layer transfusion assembly (20) that includes a build platform (28), and is configured to transfuse the heated layers (22) onto the build platform (28) in a layer-by-layer manner to print a three-dimensional part (22). The transfusion assembly (20) includes a nip roller (320) configured to deform when transfusing the heated imaged layers (22) to reduce deformation of the layers (22).
