Abstract
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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
86 words
A method for producing an object by laser beam spraying comprising the steps of directing 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, and three-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.
Claim 2
Independent Claim
86 words
A method for producing an object by laser beam spraying comprising the steps of directing 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, and three-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.
Claim 3
Dependent Claim
17 words
A method according to claim 1, wherein the at least one material is a plurality of materials.
Claim 4
Dependent Claim
16 words
A method according to claim 2, wherein the plurality of materials are a plurality of metals.
Claim 5
Dependent Claim
16 words
A method according to claim 2, wherein the plurality of materials are a plurality of ceramics.
