COVID-19 Production of Sterilizable HEPA Filter Shell

Project Overview

Due to supply concerns, local doctors are in need of reusable (sterilizable) housings for respirator circuit HEPA filters. This project team is researching 3D printing of autoclavable materials (e.g., fused deposition modeling of ULTEM) to fabricate these requested parts.

The HEPA shell design feature a double ring and snap-together assembly. Once finalized, this team could potentially produce up to 200 shells per week.
