Hey everyone,

This started as a problem of our own. My friends and I run small 3D-printing and composites projects, and making molds was always the part that dragged everything down. Splitting the part, adding pour channels and vents, designing keys so the halves align: it ate hours of CAD time, and a small mistake meant a failed cast. We figured other small makers and startups were stuck on the same thing, so we built MoldStudio3D.

It runs in your browser, with nothing to install. You take a design, and it generates a mold ready to print.

The workflow (7 steps):

1. Open the studio
2. Pick a designer (ribbed, twisted, bubble, and more) or load your own file
3. Generate your design
4. Send it to the Mold Suite
5. Choose your mold type (silicone mold, for example)
6. Generate the mold
7. Prepare the export and print

On the site there’s a step-by-step walkthrough with screenshots and recordings, following one candle from design to finished silicone mold.

What we’d love to know from you:

• What kind of molds do you make most (silicone, composites, resin, candles, something else)?
• What shapes or mold types should we support next?
• Where does the workflow feel slow or confusing?

We’re still improving it, and every comment helps us decide what to build next. Happy to answer any questions about how it works.

I have no experience in mold making, im assuming I could scult it out of clay but what type of mold would I need to make? And what type of silicone for casting?
