The Monterey County library system buildings have been closed due to the ongoing coronavirus pandemic, but the system’s two 3D printers are still providing an essential service to the community - printing N95 masks for frontline workers.

County officials say the two printers are running all day to print plastic N95 masks. 

“We know there is a need for these, so my team tested the masks to pick the best pattern and materials and worked out the bugs before starting the printing work,” says library director Hillary Theyer. “These printers were located in Soledad and Greenfield Branches and have been moved to the County surplus warehouse where the printing is taking place. “

The masks are hard plastic and can be reused by the same person. Each mask takes over three hours to print and will be donated to health and safety agencies.
