Build Your Own SLA/SLS

Beautiful, thanks for the effort.

Put some beer money on top of those sheet prices, at least.

You just made Phife filthy rich so I'm sure he'll show he's gratitude

I will wait until one of you shares the prices with us. I would advise anyone else to do the same, no point in clogging their emails with individual questions.

Yeah I'd say that's good way of going about it.

Just be sure to mention that you would be interested in more than one piece, as there would be many of us ready for an order.

That would depend on the printer, resolution and build size you want to use it with. Let's say that 1920x1080 resolution and 0.1 is the standard today, that means a build size of 192x108 mm, but you need extra size to account for the tensioner and the clamp so I would say: mininum: 300x220 mm (for 0...

Oh in that case I think you can count on quite a few here, for a bulk order. The rest of us could split the bill for your sheet, for your trouble. Well, the thinnest fep sheet is 0.0125mm I believe, then 0.0250 is the most common. That's regular fep film. Carbon3D uses 0.063mm sheet of Teflon FA, so...

Teflon AF has extremly good physical properties, just like fep film. Carbon3d says they have it higly tensioned so I don't see a problem here.

I guess any film manufacturer could produce custom sizes, but not with a 100ml boťtle. Maybe if we brought 100,000$ worth of the stuff.

I think that 100ml of the 1% solution means you only get 1ml of pure solid AF out of the bottle after the solvent evaporates. So you would need 20 bottles for a 0.05mm 400x500 sheet. Anyway there is regular teflon in liquid form, so maybe experiment making sheets with that, or any other similar but ...

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...

Now you're talking, group buy in custom sizes!

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.
