Learn how to embed magnets in 3D prints without glue, messy assembly, or pausing the printer mid-print. We cover several magnet-retention designs that are cleaner, stronger, easier to assemble, and more reliable for production.

You’ll see how to use cylindrical magnets, side-loading slots, over-center retention features, spherical magnets, press-fit cavities, ball bearings, screws, and other metal components. These methods can eliminate polarity mistakes, reduce assembly time, maintain direct metal-to-metal contact, and prevent magnets from loosening as printed materials creep over time.

These techniques are especially useful for magnetic lids, enclosures, hinges, snap closures, modular products, and parts designed for scalable 3D printing.

Portals allows creators to upload a model, include components such as magnets and screws, and sell finished 3D printed products without operating their own print farm.
