Case In-Depth Analysis: MS1 3D Printed Turbine Shaft for Offshore Wind Energy System
An offshore wind turbine manufacturer required a lightweight yet ultra-strong turbine shaft capable of operating under continuous dynamic loads in a marine environment. Using our carbon steel 3D printing service with Tool Steel MS1, we produced shafts achieving tensile strength above 1950 MPa and density over 99.5%. Topology-optimized hollow structures reduced shaft mass by 20% without compromising torsional strength. Post-processing included HIP treatment and CNC machining to meet aerospace-grade surface finish and concentricity tolerances.
