I bought the formlabs printer specifically for casting jewelry, found out no caster near me would cast the castable resin, but I found one who would make silicon molds from either the castable of the regular resin. That was a relief. Here are a few pieces I’ve made with this process.

Very nice Kathleen, particularly like the facial expressions, any idea what silicon they use? Mine reacts with cured & uncured resin which is annoying because I’m casting to make master patterns for moulding. It would be great if I could miss out the initial casting step.
He uses a yellow silicon. There are about 7 silicon and rubbers available for molds, but only the yellow and the clear would work with resin models.
These look great! You might check out this thread for casting houses that work with Formlabs Resin.
I appreciate you pointing me there, but I’ve already been. I got ghosted by a couple of those places, the rest were just too far away. And anyway, I’m in the land of the casters in New York. I had a bunch of local people turn me down. One was nice enough to explain why. He said he didn’t want to change his setup for a few jobs and more often than not the pieces weren’t properly cured, which is a huge waste of time and resources… I showed another friend who does casting the burnout schedule and he said FIFTEEN HOURS??? That’s when I decided to look at different options.
You should try Bluecast castable resin for jewelry. It needs NO curing at all and prints really well, Only needs a fast alcohol bath and air dry for a 30 minutes and it is ready to be cast. It can be cast with regular wax burnout schedules or even a fast 2 hour burnout. I’ve had my pieces cast by 2 different casting houses with no issues at all. It is cheaper than formlabs castable resin and produces clean and smooth castings.

The Bluecast resin is sold by 3D Garage and their customer service is fantastic, check them out https://www.facebook.com/3dgarage.bg/
Bluecast resin comes from Italy, but they ship everywhere. I am in Canada and my shipment arrived in just 4 days via Fedex.
Your pieces are beautiful Kathleen!
Do you finish them with liver of sulphur and brush for highlights?
Yes. Liver of sulfur but more than brushing. I think they are silicone thingies I used for the highlights. That punched more.
And thank for the compliment.
