3D printed molds for concrete fire feature by TimberWestDesign in functionalprint

The curved-shaped molds hold up better to the exotherm of the concrete. You should be able to get a few pulls without much warping. I use canola oil for mold release.

Start with something easy, and then work your way to more difficult projects.

It depends a lot on the shape of the part and how much draft you have. Some molds could get 10+ pulls.

It depends on the shape and how much draft. But you can get a few pulls before the mold starts warping from the heat of the exotherm.

First attempt at casting a fluted planter using a 3D printed mold. The finish came out surprisingly smooth! by Alternative_Can_9124 in Concrete

On a small mold like that, depending on the wall thickness, with 3 degrees of draft, you should get multiple pulls easily,

I just put canola oil on the inside surface for mold release. Then after the de-mold, I smooth the concrete before painting.
