About

Dr. Nils Stein is a biomedical engineer whose work bridges the gap between soft tissue simulation and experimental validation. His primary research focuses on developing advanced 3D printing methodologies for creating realistic, gelatin-based phantoms that mimic human soft tissues for biomedical applications. Stein’s most notable contribution is his pioneering work on robotic 3D printing of gelatin phantoms, as detailed in his highly cited 2015 paper, which has garnered 8 citations. This study introduced a novel system capable of producing large, reproducible, and high-resolution phantoms by keeping gelatin in a fluid state during the printing process—a critical advancement for creating anatomically accurate models for surgical planning, medical device testing, and imaging research. By addressing key challenges in workspace size, reproducibility, and resolution, Stein’s work has provided researchers with a standardized, cost-effective tool for experimental evaluation in biomedicine. His efforts have significantly improved the fidelity of soft tissue phantoms, enabling more reliable preclinical testing and reducing reliance on animal models. Stein continues to push the boundaries of additive manufacturing in medicine, making him a key figure in the evolution of biomedical phantom technology.
