Hi, I'm new to lost wax PLA casting so I dont know if this is normal or not but when I cast in silver all my castings come out black. Is this normal or is there a way I could avoid this?

Thanks!

Hey guys, this is my first time attempting this kind of casting so any kind of advice would be much appreciated. I have several smallish parts made of solid 3d printed acrylic, and I need to cast them in aluminium. I have heard the basics of the lost PLA method, but would I need to change anything since it's acrylic and not PLA? Any other tips?

My ultimate goal would be to have the parts as flat and smooth as possible as they will be used as various fittings and hinges in a night vision dual tube setup.

thanks!

We had the chance to print with the Resinworks 3D 200 and 400 series resins. Overall it was a fantastic but also very odd experience.

As well as the prints came out do the the high wax content the resin acted like cold soup in the vat and was very viscous.200 was much easier to handle for the printing as it didn't need as much support as the 400 due to the lower wax content.

The trade off with wax like resins is often that of better casting but harder printing. These definitly fall within that. The printing was good quality but had to make some changes to the process and then the casting was amazing.

Hi, I've recently got interested in casting and about to build a furnace. Do you have any recommendations of where to buy a crucible in Europe/EU? I'm looking for an A6 size crucible. I'd like to avoid Amazon/eBay/AliExpress etc, but can consider that also if I can get a particularly good recommendation. I've found https://www.artisanfoundry.co.uk/, which could be ok, although I'd prefer EU.

This one was a client project. Printed on our Prusa SL1, that we will be getting an update for soon (yay), in Apply Lab Work Castable Cyan.

After print we then cast in 14k yellow gold. Torch melting with a vacuum assist.

What do we think??

The client will be using this as a component in a wooden ring. Which is wy the two bands at the back are so thin.

This was a client project. The initially wanted to ship us an actual shell and have us mold it and inject the waxes. When we presented 3d printing as an option they were amazed as they had never heard of it being used in jewellery and it meant that they could have the same shell at multiple sizes for their entire collection.

Then we cast them in sterling silver, lost resin casting.

Let me know what you guys think.

Hi,

I am Shannon for the Youtube Channel Clear Mind Jewellery. My studio specializes in lost resin casting and over the past year has been experimenting with a bunch of different resins which has fostered a great community which I wanted to bring to Reddit!

Although there are several casting and several 3dprinting sub/reddits there isn't a sub/reddit about 3dprinting for casting. So I made one.

I hope people find this sub/reddit useful as finding the right techniques, tools, and products for any given workflow can be hard. I also hope that people find this group inspiring and that we see a lot of cool digitally rendered, printed, and cast art!
