WIPO Patent Application WO/2014/020085

A3

A machine (1) for the additive manufacturing of a three-dimensional object by sintering or melting powder (2) using an energy beam (3) acting on a layer of powder in a work area (4), said work area being defined in the upper portion by: - a construction liner (41) fixedly mounted inside a frame (40), inside which liner said object is manufactured supported by - a manufacturing table (7) which slides inside said construction liner (41) when it is driven in vertical translation by - the head (32) of a ram (31) positioned along the central axis of said liner. According to the invention, said manufacturing table (7) is disposed inside a transport container (60) which is arranged removably between said liner and said ram (31), - the machine comprises means for moving the transport container (60) vertically into contact with the construction liner (41), and - the container is open at the top and at the bottom such that, when the ram (31) is actuated, the head (32) thereof can transfer said table (7) between said transport container (60) and said construction liner (41) that forms a construction frame around said table.
