How to get clear flexible resin ? (like the old one)

Hi everyone,

We need the old clear and flexible resin, to craft parts that must be translucent…
I would be very surprised that Formlabs doesn’t keep offering it, because it’s just very useful.

Anyone use this resin ?
How do you obtain it ?
Does Formlabs keep producing this material ?
Can I use a material from another brand ? Wich one ?

I loved the look of that stuff too. I have one expired half-litre bottle still sealed in the original packaging that I’d be hard-pressed to part with.

I think @Dudemeister experimented with a 3rd party alternative.
