Additive Manufacturing

Metal Additive Manufacturing (AM) has seen significant progress in recent years and has become increasingly popular; however, data base of knowledge for mechanical behavior of AM metals is not as extensive as that of wrought metals. Our lab is developing various methods of predicting the behavior of additively manufactured materials including metals without the need for extensive testing. We are looking to improve our understanding of mechanical properties of additively manufactured materials and expand the capabilities of predicting their behavior under different loading conditions.

Subtractive Manufacturing (Machining)

AM metallic parts are currently manufactured for end-use applications in various industries, such as aerospace. However, there are still major concerns about dimensional accuracy, and surface quality of as-printed AM metals. These issues are more pronounced in additive manufacturing of parts with complex geometries, and they negatively impact the fatigue resistance, which is highly sensitive to surface quality. As a result, additively manufactured metals usually require post process finish machining.

Hybrid Manufacturing; A Combination of Additive and Subtractive Manufacturing

Employing a hybrid of AM and subtractive manufacturing (SM), such as machining, combines the design and manufacturing flexibility of AM with the high surface quality and dimensional accuracy attainable from SM.
