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.

Build platforms with a flexible element

A 3D printing apparatus is disclosed herein. The 3D printing apparatus comprises a non-powered compartment defining a chamber to contain build material, and a passive latching element connected to a lateral wall of the compartment to be engaged with a complementary latching element of a platform. A drive mechanism of a 3D printing device is engageable with the platform to apply an upward vertical force to the platform to move the platform upwardly. The complementary latching elements are to: passively latch the platform and the compartment together at a latched position such that upward movement of the platform causes upward movement of the compartment until the compartment is restrained at a sealing position; and to passively unlatch the platform from the compartment, upon further upward movement of the platform.

3D printing non-powered compartments with passive latches

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.
