This invention concerns a module for insertion into an additive manufacturing apparatus. The module comprising a frame (201) mountable in a fixed position in the additive manufacturing apparatus, the frame (201) defining a build chamber (205) and a dosing chamber (206). A build platform (207) is movable in the build chamber (205) for supporting a powder bed during additive manufacturing of a part. A dosing piston (210) is movable in the dosing chamber (206) to push powder from the dosing chamber (206). A mechanism (219a, 219b, 220) mechanically links the build platform (205) to the dosing piston (210) such that downward movement of the build platform (207) in the build chamber (205) results in upward movement of the dosing piston (210) in the dosing chamber (206). |
