DO NOT USE THIS IN LIEU OF CERTIFIED PERSONAL PROTECTIVE EQUIPMENT.

The fast-moving CoVID-19 pandemic is stressing supply chains even for some of the best prepared medical facilities. Due to this, states and local institutions have taken it upon themselves to address supply shocks, particularly in mobilizing locally available materials and resources to fabricate urgently needed personal protective equipment (PPE). Many of these initiatives are leaning on advances in additive manufacturing capabilities such as 3D printing.

The PABR design and accompanying information, including this guide, are intended to assist in such endeavors. We would like to share designs and details on a quick, simple, and low-cost adaptation of half-mask respirators.

NOTE: THE PABR IS NOT INTENDED TO REPLACE STANDARD CERTIFIED PPE.

While some preliminary testing has been conducted, the use of the PABR assembly has not been fully tested. THE PABR HAS NOT BEEN CERTIFIED BY THE FDA, NIOSH, OR ANY OTHER STANDARDS BODY. Further, since 3D printers and print material vary in properties and capabilities, you should fully test the PABR once it is assembled to account for any variances that your manufacturing environment may have introduced.
