Abstract

Nowadays, different methods are used in manufacturing sector. One of these is the production technique on 3D printers, which is also described as additive manufacturing. In this study, Pelton turbine bucket was produced from composite material (carbon + thermoplastic) on a 3D printer and tested. Analytically, the special pelton turbine bucket designed at TEMSAN has a special form structure. Through additive manufacturing, the turbine runner was manufactured faster and more cost-effectively compared to production out of steel material. Tests were carried out in TEMSAN Hydraulic Test Laboratory at 5-7.5 bar pressure range and 26 l/s and 46 l/s flow rates. The highest breaking strength value was determined as 1775 N.
