I will design a 3d mold 3d printable plaster mold for ceramic slip casting
Alexandra M
About this gig
Want to make ceramic pieces in batches, but don't want to sculpt a mold by hand? I design the 3D files you need for slip casting, so you can print them and pour your own plaster mold.
I create the master model of your piece and the mold case (the walls and parts you pour plaster into), scaled for your clay's shrinkage. Each mold is planned for easy release: draft angles, registration keys so the halves line up, and a pour spout that works with your slip.
What you receive:
- Print-ready STL files for the model and the mold case
- STEP files on Standard and Premium
- A preview image to approve before you print
- Short notes on printing and pouring
Good for cups, vases, bowls, figurines, planters and small tableware.
I design the files only. Printing, plaster, clay and firing are done by you. Test your first mold before a large batch.
Message me your idea, the size and your clay's shrinkage rate, and I'll send a clear quote.

I design 3D molds for makers and small businesses who need their ideas to cast, print and release cleanly. Whether it's a soap bar, a resin charm, a candle shape or a chocolate piece, I focus on the details that decide if a mold actually works: draft angles, wall thickness, pour holes and air vents. You send a sketch, a photo or a model, and I send back clear files and a preview so you know what you're getting before you cast. I reply quickly and keep every project simple and honest. Let's talk about your idea.
FAQ
Do I need a 3D model already?
No. A sketch, a photo with measurements or a reference piece is enough. If you already have a file (STL, OBJ or STEP), send it and we can start faster.
Do you make the physical mold?
No. I deliver the digital files. You print them, pour the plaster and cast with your own slip.
How do you handle clay shrinkage?
Send me your clay's shrinkage rate and I'll scale the model to match. If you don't know it, a small test tile will give you a more reliable number than a guess.
Can you do handles, spouts or undercuts?
Yes. I split the mold into more parts so the piece can release. Standard covers up to 3 parts and Premium up to 5. For anything more complex, message me before ordering.
Will the mold fit my 3D printer?
That depends on your print bed. Tell me its size and I'll split larger molds into pieces that print and assemble.
