I will design custom silicone molds, counter molds, and dfm for casting
Sara
About this gig
Are you struggling with silicone molds that tear, trap air bubbles, or deform during pouring?
Designing reliable molds requires strict DFM principlesproper draft angles, strategic seam placement, and rigid counter-molds. As an Industrial Designer specialized in mold optimization, I will design custom silicone molds, masters, and 3D printable shells engineered for smooth demolding and low defect rates.
️
What I Design:
- Master Models: High-detail 3D files optimized for SLA/FDM printing.
- Rigid Counter-Molds (Shells): Multi-piece outer jackets to support and align silicone during casting.
- Parting Line & Air Vent Optimization: Minimize seams and eliminate trapped air.
- Draft Angle Correction: Geometry fixes for fast, damage-free demolding.
Applications:
- Candles, Soaps & Resin Crafts
- Food-Safe Molds (Chocolate, Ice, Baking)
- Concrete, Gypsum & Ceramic Casting
- Industrial Prototyping
Deliverables:
- 3D Print Files: STL / 3MF for masters and outer shells.
- Parametric CAD: STEP, IGES, F3D/IPT source files.
- Visuals: High-res assembly renders and parting line guides.
Please message me with your project sketches or dimensions before ordering so we can select the optimal mold structure!

Hi!
I'm Sara, an industrial designer with over 4 years of experience working on projects ranging from technology product design and patent registration to creating stands and advertising furniture for brands like Sony, Audio-Technica, and Blink. In addition, I have practical experience in the design, production, and standardization of modular wooden houses, which gives me a unique focus on manufacturing viability. I love transforming ideas into 3D, turning them into functional and attractive solutions.
I am known for being a very creative person, and my goal is to challenge myself in new env

FAQ
Why do I need a counter-mold (shell)?
A rigid outer shell supports flexible silicone walls during pouring. It keeps the mold from bulging or distorting under the weight of liquid material (resin, wax, soap, or concrete), ensuring consistent dimensions every time.
Can you design molds for 3D printed masters?
Yes! I design master parts specifically optimized for SLA/FDM 3D printing, including proper wall clearance and surface alignment for pouring silicone around them.
How do draft angles help my mold?
Adding subtle draft angles (tapered surfaces) allows casted parts to slide out smoothly without tearing the silicone mold or catching on undercuts, extending your mold's lifespan.
Can you help reduce bubble entrapment in my castings?
Absolutely. I analyze part geometry to add pour spouts, riser vents, or tilt-angle recommendations that allow air bubbles to escape naturally during casting.
