Looks like a good candidate for this application. Does anyone know where to find oxygen permeability data? Looking for a cheaper alternative to Teflon AF... Something capable of CLIP (so if its permeability is similar to all of the other polymers everyone here loves, nevermind).
Also thinking about how to make sure the vat membrane is flat over large areas (the weight of the resin should cause it to dip even though its pulled tight). If you had a chamber below the vat that was pressurized you could force it to bend back and flatten out, but to control the pressure you would need perhaps two red lasers (one on one side of the membrane and one in the vat) and detectors to make sure your pressure is causing the desired effect. Thoughts on this?
