Document Type and Number:
Japanese Patent JPS63230264
Kind Code:
A
Abstract:
Method of casting a shape (16) in which a beam from a laser (13) or electron gun is directed at a fusible powder (15) in a fluidized bed (1) and melts the powder, the melted powder fusing and solidifying on a surface to form the shape. Also an apparatus for casting a shape (16) which includes a fluidized bed (1) containing a fluidized powder (15), a surface within the bed on which the shape is cast, an electron gun or laser (13) for directing at the surface a beam (12) which has an energy sufficient to fuse the powder, means for controlling the level (21) of the powder in the fluidized bed relative to the surface, and means for controlling the horizontal position of the surface relative to the beam (12).
