Abstract
The motivation for research on 3D printing of protective face shields was the urgent societal demand for healthcare in the fight against the spread of COVID19 pandemic. 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.

The team members become familiar with the defined problem, the equipment used for 3D printing, the Fused deposition modeling (FDM) printing method, the material of filaments used, the testing and measurement equipment and process, and the final product
The polylactic acid (PLA), PETG, and PHA samples will be created with the 3D printer Original Prusa I3 MK3S+
Summary
Social development is significantly driven by the impact of how new technologies are evolving and expanding. One of the massively deployed newer technologies is three-dimensional (3D) printing. New, as yet unexplored, and unknown horizons emerge [1]. 3D printing can create any complex shape from the micro to macro dimension, allowing products to be designed for different areas of life. As with subtractive manufacturing technologies, 3D-printed products flow is from the invention of new ideas through the search for an application to the transformation into production, implementation, and disposal. Quality control of the additive manufacturing process is, according to [2] one of the most important technological requirements, especially in the medical [3] and aerospace [4] industries
