Title. I'm looking for resins with the lowest Shore hardness, the lowest one I've found (that I can buy on aliexpress) is Resione F39, with Shore 60-75A. Ideally, I'd want to get something closer to Shore 30-40A.

So, failing that, anyone with a higher understanding of chemistry can explain what additives are usually added, resulting in a cured resin with greater elasticity?

Formlabs sells a materials as low as 40A. Silicone 40A. Or if 50 is Ok then an Elastic 50A, or Biomed 50A.

I can't speak to if they are formulated to cure with any resin printer or only via their own.

What's your application, can you substitute geometry structure to provide "softness".

    Formlabs is WAY beyond my pay, I'm afraid. 349 USD is over 1500 BRL, and that's the price without shipping or the 96% import tax. The Resione i can buy off alie is ~60 dollars for 1L, final price.

    Not really, I'll need the squishiness on the walls, which will be 1.0-1.3mm thick

    96%? Uff, that's harsh. Where do you live?
