Why Add Magnets to 3D Prints
Embedding magnets into 3D printed parts is one of the most practical modifications you can make. Magnets allow for tool-free assembly, easy maintenance access, and secure closures on enclosures, project boxes, cabinet doors, and custom storage solutions. The best part? You don't need any special tools—just your existing slicer software.
The Pause Layer Method Explained
The key to successfully adding magnets to your 3D prints lies in timing. Most 3D printing slicers—including Cura, PrusaSlicer, and Bambu Studio—include a "Pause at Layer" or "Add Pause" feature that temporarily stops your print exactly where you need it.
Here's the step-by-step process:
- Open your slicer and load your model file
- Identify the layer where your magnet cavity or recess is complete
- Right-click on that layer in the preview timeline
- Select "Add Pause" or "Pause at Layer" from the menu
- Re-slice your model to apply the changes
When your printer reaches the designated layer, it will automatically pause and wait. You can then open the printer, drop in your magnets, close the door, and resume printing. The remaining layers will encapsulate the magnets perfectly.
Tips for Success
- Orient your magnets correctly before pausing—polarity matters for multi-magnet assemblies
- Test fit your magnets beforehand to ensure they sit flush in the cavity
- Use glue or epoxy if your magnet fit is loose
- Mark the pause layer clearly in your slicer to avoid confusion
- Keep the build plate clean before inserting magnets to prevent adhesion issues
Compatible Materials
This technique works with most common filament types including PLA, PETG, and ABS. For functional parts exposed to heat, consider ASA or higher-temperature materials, and ensure your magnets are rated for the expected operating temperature.
Common Applications
- Magnetic enclosure lids
- Tool organizers with snap-close panels
- Display stands with removable components
- Hinged project boxes
- Custom storage solutions
The pause layer method is reliable, tool-free, and produces clean results every time without post-processing or complex modifications.
