One of the early on-line responses was "maybe we can figure out how to 3D print these cases". It turns out that an Epi-pen is just a plastic safety housing around a normal syringe. Some discussions: https://www.reddit.com/r/news/comments/4y5481/cost_of_epipen... https://www.reddit.com/r/3Dprinting/comments/4y7f26/epipen_f...
That second discussion got heated quite fast. I agree with the downvoters though. 3D printing a medical device is not something to take lightly. Edit: Here's why I agree. You download this design from the internet, and 3D print the parts. You then assemble it. Awesome! Some time later, you get an allergic reaction. You use the pen, but it fails to work correctly. Who's responsible? The designer? You (if you're alive)…
Does the government prevent the sale of cheaper, inferior cars just because higher-priced cars are substantially safer?
Why should medical devices be any different? If the barriers to entry (e.g., costs associated with FDA approval) were lower, then we'd absolutely have some inferior EpiPens on the market. But we'd also have a lot more options, and all of them (even the best) would be ridiculously cheap compared to what we're seeing now. Wouldn't that be better overall for people who might not be able to afford one at all in the current system?
