2020 Digital Manufacturing Challenge Winners Sponsored by the Direct Digital Manufacturing Tech Group, part of SME’s Additive Manufacturing Community Western Washington University SME Student Chapter 125 Project Lead:Devon Kaufman Team Members:Nathan CardenasVíctor Manuel Hurtado-RuizReijer KolleRobert LaffertyEric LimAllison Mazurek Advisor:Dr. David Gill Winning Design: Economic Production of Helical Savonius Vertical Turbines for Natural Disaster Relief The Western Washington University team investigated the current limitations of wind turbine blades and how direct digital manufacturing could take an integral role in the production. The blade guide design in the report utilizes FDM printing in order to achieve the same complex geometry that is achieved in composite technology without costly one off molds designs, equipment and materials. The wind turbine includes a scalable design that can be fit to a variety of consumer applications and environments. The cycle time is minimized by utilizing outsourced sheet plastic and metal shafts while lead times are minimized through 3d printing rather than molds. This solution offers a low cost method of manufacturing a power source for emergency relief and communications.
