The U.S. Food and Drug Administration has awarded Formlabs an emergency use authorization (EUA) for a 3D-printed part designed to convert BiPAP machines designed for sleep apnea into much-needed ventilators. The offering was one of dozens of ventilators and accessories granted such authorization over the weekend.

The company plans to devote 150 3D printers at its Somerville, Mass. plant to producing the part, which it says it will then distribute to hospitals and local governments throughout the U.S.
