Abstract: In one example, a rotatable delivery module is controlled to rotate in a first direction to a supply position to enable material to be supplied to an additive manufacturing platform. During such rotation to the supply position the rotatable delivery module contacts and collects respective portions of said material contained by the material supply module. An amount of material within the material supply module is determined based on a resistive force exerted on the rotatable delivery module as the rotatable delivery module collects said respective portions of material.
