Re: Carbon 3D
Yes, I can confirm that the majority of materials that are listed as gas permeable, are in the range of up to 1 Barrer. Without an exact number it's not likely to be anywhere near Teflon AF or Silpuran permeability of 500-1000 Barrers.

Re: Carbon 3D
I have talked to the manufacturer this bio film hashigh gas permeability.
I suspect is Teflon 1600 AF

Re: Carbon 3D
Ive been emailing and calling Random Technologies for the last two weeks with no luck. No reply to my emails and when I call I get transferred to sales who never answers and his mailbox is always full so no way to leave a message.
Ive been looking into getting a sample of the resin and seeing about making my own film, but if I cant get a free sample it will be a while before I can come up with the $1800USD for a bottle of the stuff.

Re: Carbon 3D
1800$ is a 25g bottle of solid TeFlon AF in powder form which you have to mix with a solvent anyway to make sheets.
250$ is a 100ml bottle of pre-mixed liquid Teflon AF mixture, with 1% solid content. It would be enough for three 192x108mm 0.01mm sheets. I know you're using larger lcd but why risk a big failure when you can start small.

Re: Carbon 3D
I see that, not sure if that $250 deal would even work, not sure what it means by solids.. Also, Im in Canada and thats a US only site. Ive emailed them a couple days ago though, so just waiting to hear back.
I got TPX films from CS Hyde coming, Ive got some Nanocoating for glass now that I am testing on the Willow Glass samples I got. Hopefully the next few weeks we should have a better idea which works best.
Has anyone been able to contact Random Technologies? Or actually ordered any Teflon AF from anywhere?

Re: Carbon 3D
Ok I got a supplier in Canada for the Teflon AF 2400 in Solution. $250USD. There is a 45 day lead time. Im going to do some research into making the film. If I make 50micron thick film I should only need 20ml of the 100ml for a sheet large enough for my vat so I could make a few experiments.
Looking into spin coating, but it doesnt look like its used on surfaces this large (500x400mm). Anyone know anything about making 50-100micron films in large sizes?
