Lost Resin Casting for Hard Core Silver Pours

I love a good piece of hand poured silver and there are a few Artisans in and around the Silver Gold Stackers Community here on Hive who produce some sexy silver pours on the regular, however today I came across an artisan in Australia who has blown my mind with the work he produces. He uses a technique called Lost Resin Casting and it’s something I hadn’t really looked into before.

Basically you use a 3D printer to print an object out of resin and then create an Investment Cast with it. The resin is burnt out of the cast as it is cured in a kiln and then the silver is poured into the void of the cast with a vacuum on the plaster to ensure the void is filled. After the metal cools the cast is broken and the metal piece can be trimmed, polished and finished off.

It sounds like a bit of work and it does mean that there is only ever one pour per cast, but the results look spectacular. I’d like to share some pictures but probably should get permission to do so first...and I should try to add some to my stack too! The artisan I’m talking about is called Smithys Bullion and he seems to be fairly active and proliferate with his pours.

Does anyone else here in SGS have experience with doing Lost Resin Casting? I was always of the impression that moulds were made to be re-used or that artisans used sand for casting one-off pours but this Lost Resin Casting looks seriously next level to me. If you want to learn more about this method for pouring silver, I found this great video that explains and demonstrates the whole process.
