I work with a private artist from Russia. Due to the war they havent been able to get their shop running again but hopefully soon they can, I found them on Etsy.
They are sculpted digitially first, 3D printed. Then they use polymer clay and hand paint it. I believe that is the process, I haven't asked yet but I have seen unpainted 3D prints. They come out quite beautiful. Sadly, I have to self repair a lot of the time because the trip from Russia is so long. The same thing happens to my resins I buy from China. I've learned some paint and repair skills from all this lol.
