Abstract: Systems and methods for controlling the transfusion pressure in an additive manufacturing system are described. The system has a layer transfusion assembly that can include a build platform. The layer transfusion assembly is configured to transfuse the layers at a transfusion pressure in a layer-by-layer manner onto the build platform to print a three-dimensional part, and a controller is configured to set the transfusion pressure, wherein the transfusion pressure can vary along the x-direction of the build platform in a controlled manner.
