Comparative study by life cycle assessment of an air ejector and orifice plate for experimental measuring stand manufactured by conventional manufacturing and additive manufacturing

Original language description

An integral part of the rapid development of modern technologies is additive manufacturing (AM) or three-dimensional (3D) printing, which produces specific products that can replace the classic subtractive methods of machining or conventional manufacturing (CM). This study assessed the manufacturing processes of these two methods during the production of an air ejector and a centric orifice plate using the life cycle assessment (LCA) with the cradle-to-grave method, supported by experimental measurements. This study presents a comprehensive assessment of the energy and material flows during the processes of mining, production of semi-finished products, processing of byproducts, and subsequent recycling. Moreover, it includes an assessment of the production of emissions and their effect and impact on the environment and, subsequently, the social aspect. It was found that from a primary energy demand (PED) perspective, AM single build is 30% more demanding in the case without recycling and 27.5% more demanding with the inclusion of the end-of-life phase. Moreover, the impact of AM is greater in four out of six impact categories for the ReCiPe 2016v 1.1 methodology. In addition, for the CML 2001 – Aug. 2016 methodology, AM is greater in four out of five categories. Finally, AM is greater in four out of four impact categories for the EF 3.0 methodology. The study highlights the hypothesis based on the production time for the full build, where from a PED perspective, AM with the end-of-life phase is only 2.76% and 3.89% more demanding with and without the offsetting of time deviation, respectively. The results of this study discuss the potential development and reduction of the burden on the environment during the life cycle of AM, especially during the cooling AM and the production of metallic powder. Although previous studies compared AM and CM were conducted, common and simple rotating components were virtually absent. This study aims to address this problem and arouse interest in the development of the issues presented.
