NIH 3D Print Exchange's COVID-19 supply chain response effort
NIH 3D Print Exchange was developed to allow for the distributed design, testing, approval, and sharing of scientifically-accurate models related to the biomedical sciences.
In response to the COVID-19 pandemic, they have created a COVID-19 supply chain response section on their website. Here, designers of PPE (personal protection equipment) and other necessary equipment related to the pandemic can upload their designs for testing, and if approved, for clinical use.
You can scan and download the approved 3D print designs and you can do the same with the prototype designs under review. A section called "Designs Optimized for Community Use" is for things that anyone can make use of, like contactless door openers. There is also a section with designs with serious safety implications. As you might imagine, most of these are for ventilator components.
