Method for producing object by laser spraying and apparatus for conducting the method
First Claim
1. A method for producing an object by laser beam spraying comprising the steps ofdirecting a laser beam to pass near an object-forming table capable of being three-dimensionally controlled in position and attitude,melting at least one material by passing it through the laser beam and conveying the molten material to a prescribed location on the object-forming table, andthree-dimensionally controlling the position and attitude of the object-forming table for enabling the molten material conveyed thereto to deposit thereon and form an object of prescribed shape.

Abstract
A method for producing an object includes the steps of directing a laser beam to pass near a multiaxis table, supplying material from a material supply device to pass through and be melted by the laser beam, conveying the molten material to a prescribed location on the multiaxis table by allowing it to fall under its own weight or conveying it with a carrier gas, three-dimensionally controlling the position and attitude of the multiaxis table by means of a controller, and progressively depositing the molten material at prescribed locations on the multiaxis table for producing an object of a prescribed shape.

7. An apparatus for producing an object by laser beam spraying comprising
an object-forming table equipped with means for three-dimensionally controlling its position and attitude, laser beam emitting means for emitting a laser beam to pass near the object-forming table, material supply means for supplying at least one material into the laser beam, and conveying means for conveying material melted by the laser beam to a prescribed location on the object-forming table, whereby said object is formed into a prescribed shape by three-dimensionally controlling the position and attitude of the object-forming table for enabling the molten material conveyed thereto to deposit thereon.

9. An apparatus for producing an object by laser beam spraying comprising
a chamber, a table disposed inside the chamber and equipped with means for three-dimensionally controlling its position and attitude, material supply means provided above the table for supplying at least one material to the table, a laser beam source for directing a laser beam through the space between the table and the material supply means for melting the material, and conveying means for conveying material melted by the laser beam to a prescribed location on the table.
