    Influence and Potential of Additive Manufactured Reference Geometries for Ultrasonic Testing by Stefan Keuler, Anne Jüngert, Martin Werz, Stefan Weihe

    Published 2025-07-01
    “…This study researches and discusses the impact of different manufacturing-induced effects of additive manufacturing (AM), such as anisotropy on sound propagation and attenuation, on the production of test specimens for ultrasonic testing (UT). It was shown that a linear, alternating hatching pattern led to strong anisotropy in sound velocity and attenuation, with a deviation in sound velocity and gain of over 840 m/s and 9 dB, depending on the measuring direction. …”
