About this gig
SILICONE MOLD & 3D CAD DESIGN FOR MANUFACTURING
Are you looking for a precise, production-ready silicone mold or CAD model for slip casting, injection molding, or plastic parts?
You're in the right place.
I specialize in custom silicone mold design and 3D CAD modeling optimized for real-world manufacturing, not just visuals. Whether you have a sketch, reference photo, STL, or just an idea, I can turn it into a clean, accurate, and functional mold design ready for casting or production.
What I Can Design:
- Silicone molds (1-part, 2-part, multi-part)
- Slip casting molds (ceramics, plaster, clay)
- Injection moldready CAD models
- Plastic mold designs
- Mold-ready 3D files (STL, STEP, OBJ)
- Custom product mold concepts & prototypes
Even if your idea isnt fully formed yet, Ill help you refine it into a functional, manufacturable design.

FAQ
Can you design a silicone mold from just an idea or rough sketch?
Yes. You don’t need a finished drawing. A rough sketch, reference photo, hand drawing, or even a written description is enough. I’ll help you refine the idea into a functional, manufacturable mold design while considering demolding, tolerances, and real-world use.
What types of silicone molds do you design?
I design 1-part, 2-part, and multi-part silicone molds, depending on the complexity of the object. This includes molds for resin, epoxy, soap, candles, concrete, plaster, ceramics, and similar materials.
Do you design molds specifically for slip casting and ceramics?
Yes. Slip casting molds are designed differently from standard molds. I account for wall thickness, shrinkage, release flow, and clean separation, making the mold suitable for ceramic, plaster, or clay slip casting processes.
Are your designs ready for real manufacturing or production?
Absolutely. All designs are created with real manufacturing constraints in mind, such as draft angles, parting lines, tolerances, and demolding clearance. The files are clean, manifold, and production-ready, not just visual models.
Can you design injection mold or plastic mold CAD files?
Yes. I create injection mold–ready CAD designs with proper draft angles and geometry suitable for plastic molding. For complex industrial molds, I focus on design-for-manufacturing (DFM) principles.
What file formats will I receive?
You will receive STL, STEP, or OBJ files depending on your package. If you need a specific format for your manufacturer or software, just let me know before delivery.
Will the files be suitable for 3D printing?
Yes. All files are checked to ensure they are watertight, manifold, and optimized for 3D printing, whether you are printing the mold itself or a master model for silicone casting.
Can you modify or improve an existing 3D model or STL file?
Yes. I can repair, optimize, or redesign existing files to make them mold-ready, including fixing geometry issues, adding parting lines, or adjusting dimensions for casting.
Should I contact you before placing an order?
Yes, strongly recommended. Messaging first helps clarify requirements, avoid misunderstandings, and ensure you select the correct package for your project.
