Shape Deposition Manufacturing

Abstract

One challenge for solid freeform fabrication has been to develop the capability to directly
\ncreate functional metal shapes which are dense, metallurgically bonded, geometrically accurate
\nand with good surface appearance. Shape Deposition is a manufacturing paradigm which attempts
\nto address these issues. It incorporates the advantages of several processes including solid freeform
\nfabrication (complex geometries, rapidly planned), 5-axis CNC machining (accuracy,
\nsmooth surfaces), shot-peening (for stress relief) and 'microcasting' (a high-performance, weldbased
\nmaterial deposition process). These processes are integrated within a CAD/CAM system
\nusing robotic automation. This paper will present the current research in this effort.
