This is a 3D printed respirator that can use any filtration material provided that it can be cut into a ~2" circular patch. The patch is secured to the mask with a threaded filter assembly. Mask sealing against the wearer's face is acheived with a cast silicone gasket. The STL files for the mask and the gasket mold are provided.
Models developed by Bucknell University College of Engineering in collaboration with PPE For Central PA
Dear author,
In order to proceed with your submission, we need to make sure specific print instructions are included in your design for users to properly recreate the model.
Please include best printing parameters for your design and update the submission at your earliest convenience.
It would also be best if basic casting instructions are included for people making the mask.
Sincerely,
VA REVIEW TEAM
