Somos resin - I need a few kg for testing

Looking for a couple of kg (2) of Somos resin for testing. I am not too picky about which resin although I need a 355nm product and I am happy to pay for it.

All the distributors I have called seem to indicate a 10kg minimum order and that is a bit out of the budget for this test

As an alternative to the Somos you can use any of the UV through visible spectrum cured photopolymers by [bucktownpolymers.com]

They will cure quite rapidly at 355nm and have a few options for small quantities of different formulas with Paypal links for ordering. They also have hundreds of other formulas available.

My main concern is shrinkage. I am afraid most all of the low cost resins are going to have shrinkage rates which will make anything but small (jewelry size) parts a mess of distortion.

Good low shrinkage epoxy resins for stereolithography were introduced more than 20 years ago. Surely somebody can reproduce that for a reasonable price...no?

Time is money - I would prefer to spend the money (and save time) on predictable materials. Now I just hope for affordable and predictable materials...

Photopolymers may be made to shrink, not shrink or even expand when cured. I'm not sure why you're having problems finding them. What did they say when you contacted them about photopolymers with low/no shrink?
