Abstract: In one example, an apparatus for supplying material to an additive manufacturing platform comprises a rotatable delivery module comprising a vane; and a plurality of distribution elements. In use, the rotatable delivery module is controllable to rotate the vane to a supply position to enable material to be supplied to an additive manufacturing platform from the vane. The vane and the plurality of distribution elements are arranged such that during the rotation: the vane provides a dose amount of material from a material supply module for supply to an additive manufacturing platform and at least one of the plurality of distribution elements distributes material within the material supply module so that the vane supplies a substantially uniform dose of material along the length of the vane to the additive manufacturing platform.

Abstract: According to one example there is provided a build material supply unit for additive manufacturing systems. The build material supply unit may comprise a sloping support surface for the build material, which has no hard edges, a mesh above the sloping support surface, and a vibrator to vibrate the mesh and cause the descent of build material.

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.
