A Decision Method to Improve the Sustainability of Post Processing in Multi Jet Fusion Additive Manufacturing

The improvements in terms of sustainability achievements by substituting additive manufacturing processes to traditional technologies have been widely investigated in literature. Nevertheless, a lack of information still exists regarding the impacts of post-processing phase of additively manufactured parts, even if this step usually has important economical, societal and environmental consequences. The present paper analyses the case of the Multi Jet Fusion process, due to the unavoidability of part post-processing. The main impact factors of this phase are highlighted and linked to the manufacturing conditions in order to point out the opportunities to improve the overall sustainability of the process.
