Design, manufacturing, and testing of 3D-printed fittings for ergonomic helmet CPAP devices: a case study.

ABSTRACT: This study presents the design, optimisation, and experimental evaluation of additively manufactured fittings for a custom helmet continuous positive airway pressure (hCPAP) system. The project was initiated as a rapid response to the shortage of respiratory support equipment during the COVID-19 pandemic. The inlet and outlet connectors of the helmet were redesigned to comply with the EN ISO 5356-1:2015 standard, reduce mass, and simplify assembly, while ensuring functional reliability and patient comfort. Components were fabricated using fused filament fabrication (FFF) and selective laser sintering (SLS) with medical-grade ABS, TPU-95A, and PA 2200 materials. A comprehensive assessment of material safety was performed, including tests for potential particle detachment under high-flow air
