Higher turbine temperature leads to higher efficiency. Therefore, in turbine technological development, the focus is to obtain advanced materials and cooling performance to withstand these high temperatures. Hence, as additive manufacturing allows the design of complex cooling patterns, with the employment of superalloys, that technology gained a foothold in gas turbine development. It is known that the side effect of AM is the presence of surface roughness, which, on one side, improves heat transfer but, on the other side, raises friction and causes pressure losses. For that reason, this study aims at understanding the correlation between the printing input values of selective laser melting (SLM), like material and printing angle, and hydraulic and cooling performance.
