Apparently Carbon uses Teflon AF 2400 with “with excellent oxygen permeability, UV transparency, and chemical inertness”. The stuff isn’t cheap either - it goes for around us$1500 per 25 grams. Carbon casts the bottom plate in-house. They also pump oxygen (or air?) to the plate.
Problem is - even if I managed to cast my own plate - I would be stuck with the firmware settings on the Form 2.
By the way here is the white paper on the Continuous Liquid Interface Production (CLIP) process used by Carbon:

For some people it would probably be cost effective to pay that much for a tray that won’t ever have to be replaced
I suppose so - but I’m not sure how many grams it would take of the Teflon AF2400. Could easily cost $5k - $10k for a window made of it. And for that kind of investment - it would kill me to be stuck at the current speed. So we need open firmware!
Looks like someone has made their own CLIP window:
Details are scarce, but states they used Cytop Film from http://www.agc.com/ - $1450 for 1000ml/1% = 10 grams of film.
Looks like he poured the solution in a glass container, heated for 30-100˚ (guessing celsius) for 5 hours then 100-340˚ for 3 hours. Then stretched the film using the flex vat technique.
He shows a fan that is feeding it air under it - I’m not sure if this could be adapted to the Form, thoughts?
That’s pretty sweet. I don’t see why it couldn’t be adapted…
Hey, what about the material used for contact lenses? That’s somewhere around 55% oxygen permeable…
