Abstract
In an apparatus for producing a three-dimensional object by laser sintering the object is produced by successive solidification of layers of a powder material at points corresponding to a cross-section of said object using radiation for solidifying said powder material. The apparatus includes a support having a substantially plane upper side for supporting the object, a material applying device for applying a layer of the material onto the upper side or onto another layer formed on the upper side, and a solidification device for solidifying a layer of the material by irradiation. The material applying device has a coating device and a drive for displacing the coating device in a direction parallel to the upper side of the support. The coating device has a first side face, a second side face, a base surface parallel to the upper side and facing the same, a first edge portion between the first side face and the base surface, the first edge portion including a first angle of inclination with the base surface, and a second edge portion between the second side face and the base surface, the second edge portion including a second angle of inclination with the base surface, the second angle of inclination being smaller than the first angle of inclination.
