Silicone molds are the favorite tool of bakers, chocolatiers, and artisans. With them you can reproduce complex shapes in chocolate, soap, resin, fondant, and more. But getting a mold with your own design has always been expensive and slow. Until now.
With KingsCutter you can design your own silicone mold in seconds, download it as STL, and print the positive to create your homemade mold. No 3D design skills or expensive professionals needed.
What is a custom silicone mold?
A silicone mold is a cavity shaped like your design where you pour liquid material (chocolate, resin, soap, plaster) that solidifies into the exact shape. Custom molds feature your logo, your drawing, or your text.
On KingsCutter the process is the reverse of what you might imagine: you design a positive (the raised piece) and use it to create the silicone mold by pouring liquid silicone around it. The result is a professional mold ready to use.
Types of molds you can create with KingsCutter
KingsCutter offers three specific mold products, each designed for a different use:
- Silicone Mold — Classic silicone mold. Cavity with your design for pouring chocolate, soap, resin, fondant. Ideal for batch production of decorative pieces.
- Word Mold — Mold for words and text. Perfect for chocolates with letters, names, dates, or personalized messages. Each letter is an individual cavity.
- Brigadeiro Ejector — Brigadeiro ejector. Mold with built-in ejector for making brigadeiros with your custom design.
Plus, the Silicone Mold from KingsCutter has an exclusive feature: you can enable the pour spout to make pouring liquid materials easier. A detail that makes a real difference in production.

Frequently asked questions
Is the mold actually silicone
KingsCutter generates the STL file of the positive (the master piece). You use that positive to create the silicone mold by pouring liquid silicone around it. It is the same process professionals use.
What silicone should I use
For food contact use platinum cure food grade silicone like Sorta Clear or Smooth Sil. For resin or soap any two part silicone works.
Do I need a 3D printer
To print the positive yes. If you do not have one you can order from one of our printing partners or buy ready made molds at store kingscutter com.

And if you also want the physical mold without printing it yourself visit store kingscutter com where you will find food grade PETG molds with fast delivery.
Your first design is free. Upload your image today at kingscutter com.
Can you create a custom silicone mold without knowing 3D design?
Yes, and it is simpler than it looks: upload your image or text to kingscutter.com, choose Silicone Mold as the product, download the positive STL and use that printed piece to cast the mold by pouring liquid silicone around it. Nothing is modeled by hand and no designer is hired.
The right sequence for the process
- Design the positive (the raised piece) from an image, a logo or a text.
- Print the positive in PETG or order the physical print at store.kingscutter.com.
- Pour the silicone around the positive, inside a containment box.
- Demold once the silicone cures and you have the cavity with your design.
The most common mistake is believing the downloaded STL already is the mold. It is not: the file is the positive, the master piece that shapes the silicone. This reversed workflow is exactly what makes custom-designed molds possible without workshops or metal tooling.
Facts and measurements
Concrete data from the catalog and from our own tests, each with its source.
| Data | Value | Source |
|---|---|---|
| Mold products available | Silicone Mold, Word Mold, Brigadeiro Ejector, plus the optional pour spout on Silicone Mold | Product catalog at kingscutter.com |
| Physical piece material | Food-grade PETG, safe for food contact (not PLA) | Product sheet at store.kingscutter.com |
| Washing the printed piece | Hand wash with water and mild soap; the dishwasher degrades PETG | Care instructions at kingscutter.com |
| Materials you can pour | Chocolate, soap, resin, fondant and sugar paste | Usage guide at kingscutter.com |
| Sizes in the physical catalog | 7, 8, 9, 10, 13, 15, 17 and 20 cm | Catalog at store.kingscutter.com |
| Design library | Hundreds of designs ready to adapt; the first download is free | kingscutter.com |
According to our workshop measurement, the positive of a design the size of an 8 cm cutter is covered with a single silicone pour and needs no extra container, because the positive itself acts as a wall. With large designs, a containment box avoids wasting silicone.
Which mold fits the product you sell
- Chocolate and confectionery: Silicone Mold with the client logo; the pour spout makes filling deep cavities easier.
- Soap and resin: the same Silicone Mold, with thicker walls to hold the piece while demolding.
- Text, names and dates: Word Mold, with each letter as an independent cavity.
- Brazilian sweets: Brigadeiro Ejector, built for batch production with a uniform finish.
A custom mold also changes your margins: you make the piece under your own brand instead of buying generic molds any competitor can use. You can design at kingscutter.com the positive from a client logo, order the print from the physical store and complete the line with texture rollers to finish chocolate and fondant pieces, or with the brigadeiro ejector and stamp guide if Brazilian sweets are your specialty.
At kingscutter.com the whole flow takes minutes: upload the image, choose the product type and download the STL ready for 3D printing, with the first download free and no credit card required.
