Sacha van Rheenen

Sacha has been passionate about creative modelling since he was a little boy. This passion for creation and a high interest in medicine made me want to become a surgeon. He figured he had missed the technical challenge during his bachelor’s in Medicine and started a pre-master in Technical Medicine. My interest in bioengineering grew, resulting in a master’s degree in Biomedical Engineering in February 2020. With this versatile education, Sacha developed a wide variety of skills that contribute to the production of medical devices. Within Vosfox Medical, Sacha works as an engineer and is closely involved in process development, production, and validation. He is responsible for the 3D printing processes.
