Abstract: According to an example, a device comprises a sidewall and a base movable relative to the sidewall. The sidewall and base define an internal volume for receipt of build material in an additive manufacturing process. The example device further comprises a membrane. A first end of the membrane is attached to the base such that the membrane is movable with the base. The membrane at least partially extends along the sidewall to form a flexible barrier between the internal volume and the sidewall.

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.
