“…Researchers usually assume metal AM processing energy dominates its total environmental impacts, because this is true for polymer AM; most studies cited for Figure 1 measure nothing else. Some studies also included consumable substances, such as argon for AM (Le Bourhis et al, 2014;Faludi, Baumers, et al, 2017;Yang et al, 2019) and oil lubricants for machining (Yang et al, 2019;Torres-Carrillo et al, 2020). While these studies found consumable impacts to be insignificant compared to energy, it is still more rigorous to measure them to verify their insignificance.…”

“…For example, Echin and Bondarenko [24] studied the technical specifications of manufacturing turbine blades using the forging method. Torres et al [25] also studied the method of manufacturing turbine blades using laser melting. In another study, Cygan [26] technically analyzed the manufacturing of a turbine blade using 3D printing.…”

“…However, the evaluations in these studies were mostly technical and did not address the issue of energy and material costs and wastages. Only Torres et al [25] conducted environmental analysis based on the carbon emission index.…”

“…Turbine blades manufactured using SLM, Investment Casting and Precision Machining were compared via LCA by Torres-Carillo et al [12]. Their investigation showed a decrease of CO2 emissions from 7.32 tons to 7.02 tons by switching to the AM process.…”
