MMU BOX (Experimental) TPU Multi-Material Print on Prusa MMU3 — 10 Hr Success

Описание: See what’s possible with careful tuning and advanced DIY effort using the Prusa MMU3 and the MMU BOX experimental rewind system.

In this test, the MMU BOX completes a 9-hour multi-material print of a functional wheel:
✅ TPU tire (flexible)
✅ PETG rim (durable)
✅ PLA supports
printed as a single part with the Prusa MK4S + MMU3.

⚠️ Note:
MMU BOX is now in experimental mode. Some users achieve consistent results, while others face challenges, especially with spring creep. This project is for makers who enjoy tinkering and refining hardware, not for those seeking a plug-and-play AMS alternative.
