Where and how to replace the PDMS in the Resin Vat

Can anyone tell me where can I buy to replace the silicone pad in the resin vat? and how?
Or can I print without it?

I wouldn’t suggest printing without it, I doubt the resin would release from the acrylic.

As for replacing it, there are several threads I believe both here and on formlabs forums about re-conditioning the PDMS units. I use the FEP myself so I don’t know a great deal about it, but the general gist is you replace it with a two part silicone, often one that is used for solar cells as it provides greater clarity.

Heres one such link: How to Restore your VAT!

You can use (in no particular order) Qsil 216, Smooth-On Solaris, Cell Guard ML Solar, or Dow Corning Sylgard 184.
