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 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?
Brazil. 60% federal import tax on stuff over 50 dollars (shipping costs count), plus ~34% state tax on top of the already taxed amount
That is really harsh… Good way to harm one’s own economy unless there are equivalent local products for absolutely everything.
