Research is based on a literature review that shows that objects produced by additive technologies do not always have consistent quality suitable for the given purpose of use. Besides, they have different effects on the environment and leave different footprints. The overall goal of the research was to find out the most suitable thermoplastic material for printing shield frames in terms of mechanical properties, geometric accuracy, weight, printing time, filament price, and environmental sustainability. Fused deposition modeling (FDM) technology was used for 3D printing, and three different filaments were investigated: polylactic acid (PLA), polyethylene terephthalate (PETG), and polyhydroxyalkanoate (PHA). The weighted sum method for multi-objective optimization was used. Finally, PHA material was chosen, mainly due to its environmental sustainability, as it has the most negligible impact on the environment. 1996-1944 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=166265 https://hdl.handle.net/20.500.11984/5434 Design for Six Sigma fractional factorial design fused deposition modelling PLA PETG HA environmental sustainability 3D Printing Optimization for Environmental Sustainability: Experimenting with Materials of Protective Face Shield Frames
