If you’re in the jewellery business or a freelance CAD designer, you know how crucial CAD files are for smooth operations. Whether it’s a ring, bracelet, pendant, or earring, the right 3D file format can make or break your design workflow.
Need a ready-to-use jewellery design cad file that works seamlessly for 3D printing or manufacturing? Microcad delivers exactly that—with formats like 3DM and STL, precision modelling is just a click away.
What Is a Jewellery CAD File?
A CAD (Computer-Aided Design) file is a digital 3D model that represents your jewellery design in full detail. These files are used to visualize, modify, and manufacture the final piece, whether it’s cast in gold, silver, or platinum.
Why 3DM and STL Formats Matter
3DM Files: For Editable Designs
3DM is the native file format for Rhino software. It’s ideal for editing, customizing, and rendering high-detail jewellery pieces.
Perfect for custom orders
Easily modifiable
Great for rendering photorealistic visuals
STL Files: For 3D Printing
STL files are the go-to format for 3D printing. They contain surface geometry and are ready for rapid prototyping or direct casting.
Printer-friendly format
Lightweight and fast
Compatible with all major 3D printers
Who Uses CAD Files in Jewellery Design?
From large manufacturers to small custom jewellers and design students, everyone benefits from high-quality CAD files. They’re a must-have if you’re aiming for accurate dimensions and efficient workflows.
Benefits of Using CAD Files
1. Speed Up Production
Pre-made CAD files let you jump straight into prototyping or casting, saving weeks of manual design.
2. Improve Accuracy
Digital designs allow you to fine-tune details like prong settings and stone placements with sub-millimeter accuracy.
3. Visualize Before You Build
You can preview exactly how your piece will look before spending a dime on materials.
4. Simplify Custom Orders
With editable 3DM files, you can customize sizes, settings, and motifs without starting from scratch.
