Abstract In this paper, we present a comprehensive case study of a laser-based powder bed fusion-manufactured optimized filtrate nozzle, focusing on environmental impacts and benefits. The scope of the study covers the raw material production, part manufacturing and use phases. We compare the results for similar components manufactured by conventional, mainly material-removing manufacturing technologies. Primary data, measured from processes, are utilized for life cycle assessment calculations, which are completed with database data when necessary. The results show that by exploiting the design freedom of additive manufacturing, it is possible to achieve positive environmental benefits, namely, a 40% reduction in the carbon footprint during the use phase, although the manufacturing phase per se requires a similar amount or even more resources than the conventional manufacturing route. In addition to environmental benefits, we present here some other potential benefits for using optimized, additively manufactured parts. |
