Patent ID: 11148355

Abstract:
Provided are a three-dimensional shaped object production device and method capable of producing a predetermined three-dimensional shaped object by forming a ball at a leading end of a conductive wire through use of the conductive wire based on scanned data or designed data and aligning and stacking the balls. The three-dimensional shaped object production device includes: a plate (40), on which a three-dimensional shaped object is placeable; a ball forming section configured to form a ball (13) by applying high voltage between a leading end of a conductive wire (4) paid out from a leading end of a capillary (12) and a spark rod (19) and melting the leading end of the wire by discharge energy; a positioning device configured to position the plate and the ball forming section by moving the plate and the ball forming section relative to each other; and a bonding section configured to bond the ball formed at the leading end of the capillary to another ball (14) that has already been stacked on the plate, the forming of the ball by the ball forming section, the relative moving of the plate and the ball forming section by the positioning device, and the bonding of the ball formed at the leading end of the capillary to the another ball by the bonding section is repeated, to thereby produce a three-dimensional shaped object having a desired shape.
