3d printing is amazing
I have a filament based 3d printer that can do surprisingly nice work, and Getting a SLA resin 3d printer that has 50 micron precision...
I am working on making a respirator mask of my own design that I hope will be orders of magnitude better than a cloth mask
It will use some cloth for filtration, but adds a layer of PM 2.5 filter and a HEPA CPAP machine filter...
