Due to supply chain disruption, the COVID-19 pandemic has caused severe shortages in personal protective equipment (PPE) for health care professionals. We partnered with Brigham and Women's Hospital (BWH) to develop a 3D printed face shield based on the Prusa design, modified it based on clinician input and validated it's use in the BWH Emergency Department.

‌The summary of this design and its clinical testing is available as a preprint article

This design is a remix of the Prusa design and aims to:

• ‌provide a transparent face shield that limits aerosol and splatter exposure from in front and above
• Provide ear-to-ear protection without obstructing hearing, nor access to ears with a stethoscope
• features top ventilation to prevent fogging
• be re-usable for a single user following appropriate decontamination
• be comfortable enough to be worn all day by healthcare workers
