Abstract: An apparatus for forming at least one three-dimensional article by fusing parts of a powder bed layer-wise. The apparatus comprising a powder distributor and an energy beam for fusing the powder layer. Said powder distributor comprises a first part being an elongated rod provided movable at a predetermined distance above the powder bed and with its central axis in parallel with a top surface of said work table and second part being a metal foil having at least a first and a second opposite edge portions. Said metal foil is provided between said elongated rod and said work table, said first and second opposite edge portions are attached to said elongated rod so that a distance between said first and second edge portions is smaller than the distance between said first and second edge portions of said metal foil when said metal foil is in a flat position.
