Blender to Silicone Mold: Design, Print & Cast Home Décor
Blender to Silicone Mold: Design, Print & Cast Home Décor
Design it. Sculpt it. Print it. Make the mold. Cast it again and again.
Learn how to create your own decorative tray or home décor object in Blender — a completely free 3D design program — and turn your digital idea into a real, reusable silicone mold.
In this practical 45-minute course, I guide you through the entire process: from creating and digitally sculpting the design, to preparing it for 3D printing, finishing the printed model and making a silicone mold ready for casting.
The course is created especially for complete beginners. You do not need previous Blender, sculpting or 3D modeling experience. Every stage is shown clearly, step by step.
🌍 Course language and subtitles
The course is taught in English and includes subtitles in five languages, so you can follow every step at your own pace.
What you will create
During the course, you will create a decorative, organically shaped home décor design that can be used as a tray, candle holder, jewelry dish or decorative object.
You will learn how to take one idea through the complete production process:
- design the basic shape in Blender
- digitally sculpt an organic decorative surface
- prepare the model for 3D printing
- print the finished master model
- smooth and prepare the surface
- create a reusable silicone mold
- cast your final home décor product
Once your mold is ready, you can reuse it to create multiple pieces in different colors, finishes and casting materials.
What you will learn
- How to create a decorative tray shape from scratch in Blender
- How to work with basic Blender tools without complicated technical theory
- How to digitally sculpt an organic, handmade-looking surface
- How to control the shape, depth and thickness of your design
- How to keep the bottom of the object flat and printable
- How to prepare and export the model for 3D printing
- How to clean and finish the printed master model
- How to use primer to improve the printed surface
- How to prepare and pour liquid mold-making silicone
- How to remove the finished silicone mold safely
- How to cast a finished product using plaster, cement, wax or similar materials
Why Blender?
✅ Completely free
No subscription, no monthly fee and no paid CAD software required.
✅ Windows, macOS and Linux
Blender works on most modern desktop and laptop computers.
Blender is powerful enough for professional 3D design, but you do not need to learn the entire program. In this course, you will use only the tools required to complete this specific project.
What you need
Before purchasing, please make sure you have access to the equipment and materials listed below.
💻 A computer
A Windows, macOS or Linux desktop or laptop capable of running Blender.
🟠 Blender 3D
Blender is completely free to download and use. No subscription is required.
🖨️ A 3D printer
You will need a home FDM 3D printer to print the master model used for mold making.
🧴 Liquid silicone
A two-part liquid silicone suitable for creating flexible casting molds.
🎨 Primer — optional, but recommended
Primer or filler primer can help smooth visible 3D-printing layer lines before mold making.
🏺 Casting material
Polymer plaster, casting plaster, cement, wax or another material suitable for your silicone.
The essential setup:
A computer + free Blender software + a 3D printer + liquid mold-making silicone.
To finish the project, you will also need a casting material such as plaster, cement or wax. Primer is optional, but recommended for a smoother result.
What can you cast in the finished mold?
The silicone mold can be used with many different casting materials, depending on the type of silicone you choose.
Always check that your chosen silicone is suitable for the casting material you intend to use.

- want to create your own home décor designs
- own a 3D printer and want to use it for mold making
- want to make trays, candle holders or decorative objects
- want to create products for your own handmade business
- want to stop relying only on ready-made molds
- prefer a short, practical project instead of a long software course
You do not need…
- previous Blender experience
- advanced 3D modeling knowledge
- professional sculpting skills
- expensive CAD software
- an industrial 3D printer
A complete project in only 45 minutes
This is not a long, overwhelming Blender course filled with tools you may never use. It is a focused, practical class built around one complete project.
In approximately 45 minutes, you will see the full workflow from a blank Blender file to a finished silicone mold and cast product.
Pause whenever you need, repeat individual steps and work at your own pace. You receive lifetime access, so you can return to the lessons whenever you create a new design.
Create molds that are truly yours
Ready-made molds limit you to shapes designed by someone else. Learning this workflow allows you to create objects that match your own style, your brand and your product collection.
- create unique shapes that are not available in stores
- adjust the dimensions to suit your own products
- experiment with organic textures and sculpted surfaces
- make reusable molds for small-batch production
- develop new collections without buying a new mold every time
Course access
This course gives you a repeatable process that you can use for future trays, candle holders, dishes, ornaments and other decorative products.
Ready to turn your idea into a real mold?
Start with a blank Blender file and finish with your own reusable silicone mold and a cast home décor product.
Blender is free. The course takes only 45 minutes. You pay once and receive lifetime access.
Design it in Blender. Print it at home. Make the mold. Cast it again and again.
