<![CDATA[The COVID-19 pandemic has necessitated global reliance on respiratory protection, leading to an unprecedented demand for face masks. This reliance has not only strained global supply chains but also triggered an environmental crisis characterized by a massive influx of non-biodegradable single-use medical waste. This research addresses these challenges by developing a reusable, ergonomic face mask that integrates systematic engineering design with additive manufacturing (3D printing) technologies. Using a multidisciplinary approach, we employed a design cycle comprising conceptual modeling, functional decomposition, and detailed parametric design, benchmarked against the NIOSH-approved 3M™ 6200 respirator. The prototype was fabricated via Fused Deposition Modeling (FDM), utilizing a composite material strategy: eTPU 95A for facial conformity and comfort, and PLA+ for the filter-locking mechanism to ensure structural rigidity. Advanced slicing strategies, specifically tree-like support structures, were employed to optimize surface finish and reduce post-processing requirements. The resulting prototype demonstrates the feasibility of bridging complex ergonomic requirements with rapid manufacturing capabilities. While further clinical validation and standardized filtration testing are required to achieve certified N95-level protection, this study establishes a scalable, sustainable, and customizable framework for the future of personal protective equipment (PPE) in public health management.]]>
