> This effort they're doing really doesn't seem like they're treating it like a "Hackathon" project. They're putting real engineering resources behind it. Engineers can and do hackathon work, but real engineering work is way more about verification and validation than hacking stuff together. Products need to ensure that they will work reliably within all operational limits. You don't ensure that with an all nighter and a 3D printer. That's one of the main reason why software development is not recognized as an engineering field. Verification and validation are the bread and butter, because if that culture doesn't exist and if these efforts don't happen then people die.

  Seeing as the engineers all touched their faces multiple times during the video (fidgeting with their poorly-fitted masks), I think it's safe to assume they know little to nothing about medical care, and this ventilator looks cool but will have no real world usefulness.

As you might understand from the language used and your failure to see a 3D printer, my description is what you may describe as a hyperbole. But still, to put it in terms you might better understand, why do you think that medical devices take years to design and develop and get to the market? There are more things to it other than the old tinfoil stories.

    >But still, to put it in terms you might better understand, why do you think that medical devices take years to design and develop and get to the market? Because of insane regulatory hurdles, and a refusal to adopt standards accepted by other nations' comparable regulatory agencies? See, for example, KN95 masks. Or for a non-coronavirus example, look at how slow the FDA has been to approve SLIT immunotherapy methods for allergy treatment, despite European agencies having approved them for decades. Which results in Americans seeking allergy immunotherapy to either get off-label prescriptions for SLIT therapy, or they have to get the much more expensive injections that require multiple visits a week to a doctor's office and supervision by trained (and therefore expensive) professionals.

    This sounds a little like an argument that it's simply impossible to get this done any faster, so we shouldn't try. I mean, I like to think we have clear enough standards for reliability and testing that if we manage to perform some excellent engineering and meet all of those standards in record time, and the federal government is willing to expedite the approval red tape, there's no technical reason we shouldn't be able to get it done a lot faster than what is typical without sacrificing safety. Or put another way: I really hope the safety of our existing medical devices isn't simply based on the process being slow.

  Yea, it does, right down to the graph visualization that doesn't fill the screen.

With hospitals in first world countries to larger or smaller extent already using 3D-printers to strengthen faltering supply lines I think the distinction is not so clear. Let a thousand flowers bloom and the doctors decide what they want to use. They can make the best tradeoffs.

And you need a rigorous process to insure they can be actually manufactured to specifications at scale. Which is why medical devices require so many layers of approval.
