DESIGNING VERTICAL AXIS WIND TURBINE FOR SMALL SCALE POWER GENERATION WITH 3D PRINTER

Abstract

In our modern world, where electricity usage continues to rise, the potential of wind power as a convenient and sustainable energy source cannot be overstated. The key lies in harnessing this abundant resource effectively. In conjunction with smart grid technology, small-scale wind turbines have emerged as a means to enhance the resilience and robustness of our power grids. What sets these small wind turbines apart from their conventional counterparts is their ability to capture energy from low-speed winds, making them versatile and adaptable. Unlike traditional horizontal axis wind turbines, these smaller models employ a vertical axis design, with variations such as the Savonius, which utilizes wind drag, and the Darrieus, which harnesses wind lift. Leveraging 3D printing as the primary manufacturing method for these turbines is an innovative approach. This article focuses on the quest to find an optimal Vertical Axis Wind Turbine (VAWT) design tailored for small-scale operations in low-speed wind conditions, often found in urban environments. To achieve this, a comprehensive literature study was conducted to determine the most suitable VAWT design, resulting in the selection of the Helical Savonius with three blades. The 3D model was meticulously crafted using Autodesk Fusion, followed by the setup of the 3D printer using Cura. In this article, the Ender 3v2 was chosen as the 3D printer of choice. While the printed design exhibited minor deviations of  2mm from the original, and some setup improvements are needed, the turbine holds promise for utilization in various projects, including power generation.
