Recommended methods

The methods listed below, seem to be the most promising to kill the virus and are currently being verified by the professionals. Hospitals and other medical workplaces can use their professional sterilizing equipment to properly sterilize (disinfect) the face shields before using them again. A test on a single shield is recommended to verify possible damage of the sterilization.

All tests were performed by leading Czech laboratories and hospitals to ensure conclusive and reliable results. Detailed info about the testing facility and conditions of the test are described between the tables.

The tests were conducted on the Prusa Face Shields printed from Prusament PETG Orange. The official design of the Face Shield is available at PrusaPrinters. We cannot guarantee the methods will work on a different design (geometry) or material due to different properties (e.g. PLA will melt if exposed to high temperatures).
