    This proyect is carried out in the province of Cotopaxi in the Alpama-Salcedo sector, with the aim of designing and testing a prototype of an Archimedes screw hydraulic turbine for smaller-scale power generation. CAD and CFD (SolidWorks) simulation tools and 3D printing technology were used, which allowed to create a custom design of the Archimedes screw with a diameter of 0.2 m, a length of 0.4 m, 2 blade numbers with an inclination of 42° and a screw inclination angle of 30° for correct operation, a process that took 34 hours of printing with the PLA filament. The use of fluid dynamics simulation (CFD) was used to analyze the behavior and pressure of the water by the helical surface of the screw, being an effective method to estimate the performance of the turbine. The results indicated that the Archimedes screw in simulation with controlled conditions rotates at 146 rev/min, while with the experimental prototype it rotates at 160 rev/min, indicating a correlation between both test. Estimated manufacturing costs between material, labor, and overhead add up to $406.5, making 3D technology a viable way to perform prototype validation thanks to its flexibility to performmodifications during the printing process meaning economic saving within the prototype manufacturing process. This renewable energy system takes advantage of small waterfalls abd low flowss, allowing it to operate in different variations, being a profitable option if you want to generate energy autonomously and eco-friendly with the environment.
