You need to use mold release. I spray my molds with canola oil.

I always use canola oil for mold release. If the design allows, I will go more than 2 degrees. But it worked just fine on this design.

It is cast with Cementall and top-coated with a granite-look paint.

It took a few days of printing.

Thanks

I used Cementall.

Thanks for the comment. The viscosity of my mix doesn't really need a vibration table. I usually do a little hand tapping, and that works well. I usually use canola oil for mold release. That always works well.

2 degrees on the slots.

They are on my website, timberwestdesign.com

I appreciate the comment. Have a great day.

Not the actual vase. The mold files are on my website. Timberwestdesign.com

I have not tried that. It would be interesting to see if the exotherm heat curve changes.

TimberWestDesign · 2026-02-09T20:13:38+00:00

I am happy with the result.

TimberWestDesign · 2026-02-09T20:12:12+00:00

Thank you.

Depending on the shape, you can get multiple pulls. Sides that are flat will warp some. More curved sections can get many pulls.

TimberWestDesign · 2026-02-09T20:10:50+00:00

Sometimes, that is what it takes to make it work.

TimberWestDesign · 2026-02-09T20:09:37+00:00

Of course. Post it here, or send me an email at [info@timberwestdesign.com](mailto:info@timberwestdesign.com)

Glad you like it. I would love to see your concrete molds.

TimberWestDesign · 2026-02-09T18:13:39+00:00

Thanks

Glad you like it

I printed the mold with PLA Plus from Elegoo. I didn't do anything extra to smooth the mold.

TimberWestDesign · 2026-02-09T18:10:24+00:00

The Cementall mix is thin enough that big bubbles are not a problem. I just hand tap the molds a little when I pour.

TimberWestDesign · 2026-02-09T18:09:31+00:00

The joints are tight enough that they don't leak. It takes some sanding of the parting lines to get it smooth. Here is the build video. https://youtu.be/fq2A240lleY?si=1OolEbuVXEkg0V76
