Abstract: Additive manufacturing apparatuses and methods are provided. A coater having a rake moves above a build platform. A sensor measures topography of the build platform. A rake control unit receives the topography, determines (based on the topography) an adjustment of the rake's inclination relative to a reference plane as the coater moves from a first position above the platform to a second position above the platform, and sends command signals to a motor based on the adjustment. The motor adjusts an inclination of the rake relative to the reference plane as the coater moves from the first position to the second position.
