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.
