METHOD AND APPARATUS FOR PRODUCING A 3-DIMENSIONAL METAL OBJECT, IN PARTICULAR A 3-DIMENSIONAL SOLID METAL OBJECT

摘要

The object of the invention relates to a method for producing a 3- dimensional metal object (100), particularly a 3-dimensional solid metal object (100), during which the metal object (100) is built in a vacuum using one or more metal wires (16) of different material quality that have an end 16' by: - providing a sealed work space (12) enclosing a work platform (20), - inserting the end (16') of the one or more metal wires (16) into the work space (12), - producing a vacuum in the work space (12), - placing the end (16') of the metal wire (16) above the work platform (20), - melting the end (16') of the metal wire (16) in the work space (12) with a laser beam (31) to create a molten metal unit (17), and - on the work platform (20) building a 3-dimensional metal object (100) in contact with the work platform (20) from the continuously solidifying molten metal units (17) by moving the work platform (20) and the end (16') of the metal wire (16) relative to one another The object of the invention also relates to an apparatus (10) particularly for implementing such a method.
