Case Study
Sierra Turbines Drives Innovation for Microturbines
Sierra Turbines Inc., is revolutionizing manufacturing by embracing additive manufacturing (AM) for microturbine production, challenging industry norms and aiming to achieve 95% AM even in large-scale production.
Leveraging Velo3D’s metal AM system, Sierra Turbines aims to extend the time between overhauls (TBO) to over 1,000 hours, reduce engine weight by 50%, and enhance power density by 40 times, all while streamlining manufacturing processes and enhancing fuel efficiency.
