Abstract
The Pelton Turbine is an essential machine for the production of energy in hydroelectric power plants and distributed generation micro plants, as well as in works of Water Supply Systems, in addition to models of Pumps Functioning as Turbine (BFT) in hydraulic systems, where BFT's are used as pressure controllers while generating energy. 3D Printing is a tool that can be used on a universal scale, fundamental to industrial, commercial, academic and domestic environments, as it manufactures three-dimensional parameterized models that are low cost and lower in value than alternative methods. It allows the free production of objects, mainly applied to biology, chemistry, medicine and engineering. The manufacture of Pelton Turbine in an academic environment, dimensioned to measure, for the generation of energy in a specific system and for teaching subjects in hydraulic works, is an effective and innovative teaching methodology, as it leads to immersion in content and practical development, fostering the scale up of the model. With the objective of producing a parameterized model of a Pelton turbine, for application in a pilot scale channel and consequent collection of energy potential data, using a programmed tachymeter equipped with an Arduino sensor, a turbine, tachymeter and test specimen were modeled in a BIM language (REVIT) and manufactured them with ABS material. This material was chosen because it is the lowest cost on the market. Still, in order to know the mechanical resistance of the manufactured product, the test specimen was used for the tensile strength test and compared with the data provided by the manufacturer. Two turbines of different models were manufactured and the accuracy of the project and plots were fundamental for the achievement of the objectives. The Pelton Turbine presented a higher electromotive potential for reproducing higher rpm. This is justified by the use of shell-type blades with a central slot at the end, whereas the other model had a semi-cylindrical blade and side closures. It is noteworthy the negligible cost of ABS input at R$3.51 and the short time of 2h26 to manufacture the turbine, which demonstrates the economic viability of the system.
