Abstract: An additive manufacturing apparatus for forming a three-dimensional article through successive fusion of parts of layers of a powder material, which parts correspond to successive cross-sections of the three-dimensional article includes a process chamber housing enclosing a process chamber. A rotatable support conveyor is rotatably connected to a bottom of the process chamber housing by a rotatable shaft. The rotatable support conveyor includes an opening that extends therethrough for dispensing powder material from a powder storage vessel located on the rotatable support conveyor and a powder distributor that includes a rake portion that is located between the rotatable support conveyor and the bottom of the process chamber housing.

Abstract: Described is an additive manufacturing apparatus that includes a telescopic build tank operatively connected at opposing ends to a powder table and a build table. The telescopic build tank includes at least two segments telescopically coupled to one another, each of the at least two segments comprising a set of engagement grooves located on an interior surface of the at least two segments and a set of engagement pins located on an exterior surface of the at least two segments. The set of engagement pins is configured to engage with and travel along a corresponding set of engagement grooves of another of the at least two segments, and each engagement groove comprises a first axially extending channel positioned along a single axis and having at least one closed end, the at least one closed end being configured to impede separation of the at least two segments relative to one another.
