THREE-DEMENSIONAL PRINTING DEVISE MAKING BEAD BY USING METAL POWDER

摘要

Provided is a three-dimensional printing device forming a bead using a metallic powder. The three-dimensional printing device forming the bead using the metallic powder comprises: a sensor unit collecting three-dimensional spatial information of a bead space wherein a plurality of welding lines meet; a control unit modeling a final shape to sinter the bead space using the three-dimensional spatial information; and a printing unit forming the bead inside the bead space using the final shape.
