Abstract
A method of additive manufacturing utilizing selective layer deposition includes measuring a transfuse force between a transfuse roller and a part build surface. An angular position of the transfuse roller is measured over time. A component of a transfuse force variation that is periodic in a rotational period of the transfuse roller is estimated, and a vertical position between the transfuse roller and the part build surface is adjusted to reduce pressure variations in transfuse roller force on the build part surface.
