I know there have been a good number of threads about 3D printing ventilators and other medical equipment for use during this pandemic. This is not another one of those threads.
Instead, I was asked by a former robotics parent to help spread the word about a project called VentilAid. Their goal is to design an open-source ventilator utilizing 3D printed parts. While there are a lot of designs out there currently (and a lot of risk of non-standards conforming devices being used in lieu of certified devices), this group stands out by not rushing out to have everyone make these for use in hospitals immediately (they explicitly state on their website that their prototype is meant to be a last resort device when professional equipment is missing, and that their prototype is not to be immediately used for medical purposes). Their goal is to develop an open source design that can withstand clinical trials and be used in the future if access to professional equipment is lacking. To do this, they need feedback from medical professionals and engineers so they can iterate their prototype.
This is where the vast experience of CD mentors comes in! They are looking for feedback from professionals with experience in the medical field or designing reliable 3D printed parts about their prototype - potential shortcomings, process improvements, considerations, etc. If any mentor with experience has some time to look through the documentation for their first prototype and provide feedback that can help their future prototypes, feel free to respond to them through their website or their Gitlab project.
