May well be as you predict Tim
Sorry, the company doesn't hold stock of transparent FEP, PFA, etc sheet and it will cost $700 for a 4' x 4' sheet.. They only have white PTFE sheet in stock. They say that in order to stick parts together we need to treat the surfaces in an apparently ''secret way'' for a big fee... A little research will give it up..
But first I'll try with thin tape, white translucent to mimic pigments. I'm getting ready to order the next Laser Cut parts for 3 new Vats and I'll apply the thin Teflon tape before I assemble, on inside side of all the parts for one Vat and test it..
It's easyer to find stores in the US or Europe that hold FEP and PFA Sheet in stock, so if you guys can find some samples to give them a try please do and keep us posted!

I made my own trays for the ASIGA and I used FEP clear ... it did not require Glue of any kind as they use a flexible bottom and not a hard glass bottom ( although I tried that too )The FEP clear worked very well on the Asiga, better then their material and I told them that. I also used thicker material and that was also beneficial as the thinner material could puncture and leak if a part came loose on the asiga.
Applying thin film with Glue of any kind is very tricky and easily traps airpockets which cause issues in the Prototypes.
Been there done that. Also Have to develop a method for applying the glue and eliminating any air inclusions as you try to glue it down.
I have the Nuvat coated glass from Evert and that has been working fine.
Other materials are being tested as I have time and some materials are showing real promise., BUT, any material that works is costly and ALL materials will eventually need to be replaced as they do get damaged. So far, the easiest has been the pdms to replace.
