PAPR Device

In response to urgent PPE demands during the COVID-19 pandemic, this project involved the redesign and fabrication of a rapid-deployment Powered Air-Purifying Respirator (PAPR) system. Using MSLA 3D printing for high-resolution, fast-turnaround prototyping, the original 3M bayonet-style filter interface was adapted to the widely adopted EN 148-1 standard 40mm threaded filter system. This modification enabled broader compatibility with commonly available filters and improved the system’s versatility in field use. The project adhered to standard operating procedures (SOP) for emergency prototyping and demonstrated practical integration of additive manufacturing in crisis response.
