Ultrasonic Additive Manufacturing (UAM)
Ultrasonic additive manufacturing (UAM) is an innovative method for fabricating 3D products by adding thin layers (as thin as ~0.125 mm) one on top of the other and joining them using ultrasonic vibration, directly from the computer aided design (CAD).
Compared to other main metal additive manufacturing methods, such as selective laser sintering (SLS) and electron beam melting (EBM), UAM works at temperatures much lower than the melting temperature of the raw materials (0.3-0.5Tm), avoiding melting and formation of defects associated with high temperature processing, allowing additive manufacturing of parts combining dissimilar materials. We investigate the interface interactions occurring during the UAM and after post-treatments in the similar and dissimilar material systems, and their effect on the properties of the final parts.
The research has been conducted in collaboration with Prof. Marcelo Dapino from the Ohio State University (OSU), Prof. Sudarsanam Suresh Babu from the University of Tennessee, Knoxville (UTK), Prof. Nachum Frage from the Ben-Gurion University of the Negev, Israel (BGU) and Mr. Mark Norfolk- president of the Fabrisonic LLC, Columbus, OH.
The work has been led by Dr. Aslan Miriyev and his graduate student Mr. Asaf Levy, co-supervised by Dr. Aslan Miriyev and Prof. Nachum Frage.
