Prusa and Bondtech working on a CORE One INDX?! 🙀🤯

Exciting News: Prusa + Bondtech Might Be Teaming Up on Something Big

Prusa and Bondtech may be collaborating on a new innovation for the CORE One 3D printer. A recently released image shows what's likely the CORE One equipped with Bondtech’s INDX system, using seven different filaments at once 

What's Special About INDX?

  • Slim and Smart Design: Unlike traditional systems that need a full hotend, fan, electronics, and cooling for each filament tool (like on the Prusa XL), INDX uses just one smart “tool head” and multiple lightweight passive tools. That means it's more compact and likely cheaper to make

  • Less Waste, Smarter Switching: With INDX, when switching colors or materials, there's virtually no waste. You only need a little “priming,” and the separate tool paths keep materials from mixing or contaminating each other 

  • Mix Any Material Seamlessly: Want to print with materials that usually don’t get along chemically? INDX makes it possible—especially when paired with PrusaSlicer’s “beam interlocking” feature, which helps join incompatible materials securely

What Does This Mean for Users?

If this collaboration pans out, we could see a new system—possibly dubbed “MMU4”—that rethinks how multi-material printing works. It promises more efficient switching, compact design, less plastic waste, and wider material compatibility.

We’ll hear more about this at FormNext, a big tech show happening on November 18, 2025.
