ExOne, Pitt Partner to Produce Respirator-Cartridge Reusable Metal Filters

ExOne and the University of Pittsburgh have partnered to develop reusable metal filters that fit into a specially designed respirator cartridge for sustainable, long-term protection against contaminants such as those causing COVID-19.

ExOne has 3D printed respirator filters in two metals―copper and 316L stainless steel―and a range of porosity levels for use inside a unique cartridge designed by the Mechanical Engineering & Materials Science department in Pitt’s Swanson School of Engineering. Initial testing for airflow and filtration efficiency is underway, and the filters are being optimized with the goal of adhering to an N95 respirator standard.

ExOne’s binder-jetting technology can produce metal parts with specific porosity levels that can effectively filter out contaminants while allowing airflow.
