2023 ASNT Outstanding Paper Award –

In-Situ Laser Ultrasound-Based Rayleigh Wave Process Monitoring of DED-AM Metals

CIMP-3D is honored to have supported a project that the American Society for Nondestructive Testing (ASNT) designated as one of the Outstanding Papers of 2022. 

This important work explores novel strategies for direct, layer-to-layer non-destructive evaluation of laser-power directed energy deposition additive manufacturing (L-DED-AM) processes, and could play a critical role in accelerating qual/cert activities.  The work was led by Dr. Cliff Lissenden, a Professor in Engineering Science and Mechanics and a CIMP-3D Faculty Associate, along with 4 faculty/staff from Penn State’s Applied Research Laboratory.
