About

German Frikel is a leading researcher in advanced manufacturing, specializing in robotic laser directed energy deposition (LDED) and additive manufacturing process planning. His major contributions center on developing adaptive trajectory planning and deposition strategies for complex geometries with variable overhang angles—a critical challenge in metal additive manufacturing. Frikel’s work demonstrates that overhang structures can be reliably built up to a maximum angle of 35°, enabling the fabrication of dome and tubular components without support structures. His most cited papers, including the 2022 study on process planning for robotic LDED systems (32 citations) and the companion work on tubular components (29 citations), have collectively garnered over 60 citations, reflecting strong impact in the field. These achievements are notable for advancing the practical applicability of directed energy deposition in producing near-net-shape parts with complex overhangs, reducing post-processing needs. Frikel’s research is essential reading for engineers and researchers seeking to push the boundaries of robotic additive manufacturing for aerospace, automotive, and energy applications.
