Abstract:
1. An apparatus for producing a three-dimensional shaped product, comprising: a shaping tank, a vertically movable table in the shaping tank, the vertically movable table having an upper surface, a frame body installed upright on the table, at least one of: a base plate which supports a metallic or non-metallic powder material, the base plate having a lower surface and recesses provided at the lower surface of the base plate, the recesses receiving at least two supports selected from the group of said at least one extension support and said at least one restraining support such that the base plate is supported on the at least two supports, the base plate adapted to be supported by an arrangement so that a center of gravity of the base plate is present inside one of: thereby preventing the base plate from moving horizontally, wherein the following steps are sequentially repeated: spraying one of the metallic and non-metallic powder on a surface of the base plate, with the surface of the base plate having at least a material which can be adhered to the metallic or non-metallic powder upon solidification of the powder by sintering, subjecting an upper surface of the thus sprayed powder to planarization, irradiating one of electromagnetic waves and electron beams along a layer of the powder having a predetermined thickness to a region to be shaped which is located at an uppermost position, thereby forming a sintered layer, and cutting at least one of an end part and upper surface where sintering has been performed to effect molding.
