Three-dimensional fabrication by molten metal lamination.

Abstract

Recently, the technology of rapidly making trial models and molding which is called rapid prototyping has come to be used by many fields. The object of this report is to develop the technology which creates the metallic shaped form at high speed by laminating the molten metals by the arc discharge. It is a technique of making the metal molten state, and piling it along the outline of the shaped form. In addition, the heat influence on the surface of the formed bead and the height change of the bead were observed.
