This is informational only and open for comment. I am not an expert on 3D printing, but I have found a small circle of people who’ve told me that this is not a challenge to do. The open source digital STL files to print this mask can be found here.
The company is named Copper3D. They have a host of international partners as #HackThePandemic. The patent description and drawings are posted on the site. The files are of the 3/20/2020 release.
I was going to post this without editorial comment, but I cannot. I researched this option and company for my ex-wife, who works at a small medical practice which has exhausted all searches for supplies of N95 masks. So this is where we are. This is the result of zero-sum governance. Winners-losers. Us-them. China is shipping medical aid and supplies to Europe, but not to the US. Because the president has chosen to villify them to save his own incompetent ass. So, right now, a medical practice in America is relying on someone’s ex to find a way to manufacture their own critical equipment, N95 masks, with the help of high school students.
