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.
