Abstract

Operational parameters must be integrated into turbine systems' main components, which are determined by turbine systems' functional requirements. The need for producing component designs more effectively raises the possibility of using additive manufacturing. The study focuses on the optimization of the mechanical properties of the principal components of magnetic turbines manufactured with 3D printers using Acrylonitrile Butadiene Styrene (ABS), by changing the temperature and speed of the nozzle. The approach consisted of modeling a standard test piece in CAD software and producing ABS-based test pieces using a 3D printer with print speeds of 50, 70, 90, and 110 mm/s and temperatures of 230, 240, 250, and 260 °C. The tensile properties of the samples were determined according to ASTM D638-14 Type I, and the results reveal a consistently greater tensile strength for the parts with high nozzle temperatures of approximately 250 °C and lower print speeds of 50 and 70 mm/s. At higher speeds of 90 and 110 mm/s, though the nozzle temperature has little effect on tensile strength, suggesting that the effect of other parameters is more significant. Whatever the print speed, at higher nozzle temperature (250℃), average tensile strength was improved. Control of nozzle temperature is paramount in increasing tensile strength in the 3D printing process performed at low speeds. Also, the average tensile strength is consistent and normalized. For all print speed values, a 250℃ nozzle produces consistently higher average tensile strength than a 235℃ nozzle. Analysed the parameters for print speed and nozzle temperature, providing optimal results for stronger and more reliable parts for use in turbines.

Abstract

Hot-Gas Welding is a welding process that is widely used in plastic materials. In previous studies, there was a phenomenon that occurred, namely the connection of the base material before the welding process which affected the bending strength of HDPE sheets. The purpose of this study was to determine the effect of variations in root face height and width of the anvil heating plate on bending strength, and also to determine the interaction of the two variables. The method used in this study was experimental. The hot-gas welding process, by varying two independent variables, namely root face height 0 mm, 0.8 mm, 1.6 mm, 2.4 mm and anvil heating plate width of 10 mm, 15 mm, and 20 mm, with controlled variables HDPE material with 5 mm thick, HDPE filler with 4 mm thick, hot gas temperature 250 ℃, single v bevel shape, anvil plate temperature 150 ℃ and v grove angle 60º. The results of this study indicate that the root face height and width of the anvil heating plate affect the bending strength of hot-gas welding HDPE sheets. The maximum value of bending strength is 47.14 Mpa or 85.32% of the bending strength of the parent material. The maximum bending strength value is obtained from the interaction of root face height of 2.4mm and anvil heating plate width of 20mm. Weld defects in the highest bending strength results were identified the least.
