I'd be really interested in a group buy for europe since shipping costs are huge at CS Hyde.
There is one company shipping to germany.

http://www.goodfellow.com/pdf/4591_1111010.pdf

1pc 12"x12" is at around 150 Eur, but 10pcs are at 370 Eur so it's worth a try i guess.
Anyone else interested?

I don't think TPX is that good.

Doing some unit analysis, its O2 perm is about 0.00014 Barrer.

Sipuran is 550 Barrer, and Teflon AF is 990 Barrer for O2.

Yesterday I have ordered TPX from CSHYDE.
For those who have problem with international shipping costs, you can do what I do: use shipito.com that gives you a US address, then forward it to any place you want for low prices. Last time I ordered FEP, it was $6 US shipping + $10 from shipito to my overseas home.
Regarding permeability of TPX (Polymethylpentene), It is actually 27 Barrer. (not 0.00000 something) (teflon AF is 1300). .
My only concern is its transparency, from the image it looks rather foggy.

Another 3Dprinter that was modified to act like Carbon3D!!!!

Kobus from Gizmo 3D printers has been busy developing his own top down DLP printer.

Hey Shai,

Some of the info I read about TPX said it was UV transparent, but in another section it said it was a bit foggy. I took this to mean with visible light, but I can't say for sure, since I haven't tested it. Here is some info that helped to convince me it was worth a try http://www.tydexoptics.com/products/thz ... /thz_lens/ and http://www.tydexoptics.com/products/thz ... hz_window/

Has anyone been able to find Teflon AF Film in larger sizes?

Out of the 4 companies I contacted, only 3 got back to me and none can supply the film in the sizes I need. Im still waiting to hear from Random Technologies, I might give them a phone call today and see what they say.

30mm in six minutes? Welp this just confirms its possible. Time to buy a fish tank!

Also looking into dual photon photopolymerization. :)
