Oscar Valera likes to use 3D printers to build a collection of crafts (模型), but he is now turning his hobby toward the fight against the coronavirus pandemic (新冠大流行).

In just four days, the New Jersey high school teacher has printed and distributed 200 face masks to medical professionals across the country, including Florida and Texas. He is far from done. “One woman told me what you’re doing right now is giving people peace of mind. You’re probably saving lives,” said Valera, who found a mask design posted online.

Demand for face masks, along with N95-masks and other personal protective equipment (PPE) has increased with the surge (大量涌现) of patients infected with the highly infectious virus. That has prompted volunteer 3D printers like Valera to step in to support doctors, nurses and first responders, who are all in danger of contracting the sometimes deadly illness.

In Sunnyvale, California, community workspace nonprofit Maker Nexus has been running its 13 3D printers and three laser cutters (激光切割机) nonstop. The company produced 1,800 masks for local hospitals and now has requests for another 13,000.

Elsewhere in Silicon Valley, more companies are joining in. Fremont-based PrinterPrezz, a 3D-printing medical device contract manufacturer that specializes in metal spinal implants, switched production to printing PPE after getting a request from nearby Washington Hospital Healthcare System.

Snap Lab, a unit of Snap Inc, is also producing face masks to donate to hospitals. In New Jersey, Valera said he will continue to do his part. “I don’t mind doing this,” Valera said. “I just hate the fact that I have.”
