Additive manufacturing (AM) is a group of technologies that create objects by adding material layer upon layer, in precise geometric shapes. They are amongst the most disruptive technologies nowadays, potentially changing value chains from the design process to the end-of-life, providing significant advantages over traditional manufacturing processes in terms of flexibility in design and production and waste minimization. Nevertheless, sustainability assessment should also be included in the research agenda as these technologies affect the People, the Planet and the Profit: the three-bottom line (3BL) assessment framework. Moreover, AM sustainability depends on each product and context that strengthens the need for its assessment through the 3BL framework. This paper explores the literature on AM sustainability, and the results are mapped in a framework aiming to support comprehensive assessments of the AM impacts in the 3BL dimensions by companies and researchers. To sustain the coherence of boundaries, three life cycle methods are proposed, each one for a specific dimension of the 3BL analysis, and two illustrative case studies are shown to exemplify the model.

“…However, it would be premature to call HM sustainable without a comprehensive life cycle assessment. From literature survey, it was found that scope of the majority of studies [5,6,7] focused their work on AM and were limited to measuring operational energy consumption during process. Very few studies [8,9] characterized environmental impacts of AM.…”

This paper presents an analytical model of energy consumption for Direct metal laser sintering hybrid milling (DMLS-HM) additive manufacturing (AM) of stainless steel 316L. The model is used to quantify energy consumption during production of a defined geometry with DMLS-HM process and compared with energy consumption in electron beam melting (EBM) and conventional machining (CM). The solid-envelope ratio (α) was used to quantify energy consumption and eco impact of the three manufacturing processes on three different geometry models. The Gabi database and other published literature were used to establish energy consumption during primary metal production and material shaping processes. It was found that solid-envelope ratio (α) has more impact on the energy model of the additive processes than on the subtractive machining. On average, the percentage change in α is equal to the percentage change in energy consumed by DMLS-HM and EBM. The CM process had very little average change of 1.5% compared to the major changes in α. The DMLS-HM process showed dominant energy consumption during the part production stage with an average 84% more than EBM and CM processes. However, the CM was dominant in energy consumption during the primary production stage with an average 70% more energy than DMLS-HM and EBM processes. The novel outcomes of this research will contribute to the understanding of basic physics of energy consumption in AM and can be used in setting sustainable manufacturing goals. Moreover, energy consumption in metal AM also influences mechanical properties and microstructure of produced parts, so this work will further enhance prediction of their quality and service life. DMLS-HM is recently being introduced for industrial applications such as mold and tool manufacturing due to its capabilities in building free form and complex shapes that are otherwise challenging to manufacture by conventional methods.

Advances in 3D printing is penetrating in many industries. It is changing the way of doing manufacturing business and people's life. Performing energy and related environmental impact analysis of this technology is necessary and profound. In this paper, energy modelling is studied for FDM printing from a life cycle perspective. For a typical FDM life cycle, the stages covered are material production, printing, post-processing and related transportation. For each stage, energy consumption is modelled and measures for unit energy consumption are also proposed to assist quick calculation of a life cycle energy consumption. Besides, the machines used in different stages are analysed and the main energy consuming components are summarised. Based on a sample part, preliminary calculation of its life cycle energy consumption is presented, showing that life cycle energy saving is possible, particular with collective efforts from different stages. This offers additional data to select an energy-efficient manufacturing process.
