United StatesOriginal Prusa MMU3 Enclosed (for CORE One) - Conversion Kit
What is the MMU3?
The MMU3 is an optional add-on designed to work with our 3D printers, enabling them to print with up to five colors at the same time. It is the fastest and most efficient single-nozzle multi-material solution available, delivering excellent quality with minimal waste. Similar solutions often produce waste much heavier than the printed object - the MMU3 goes in a completely opposite direction.
Load up to five filaments of your choice, slice the object in PrusaSlicer or EasyPrint and start the print job! The rest is fully automatic. The MMU3 quickly switches between loaded filaments to deliver a stunning-looking print fast and with minimal waste. The excess material, a by-product of switching the filaments in a single-nozzle printer, is efficiently deposited only into a compact wipe tower on the edge of the print area.
The MMU3 offers great performance, high speed, and the best user experience, surpassed only by more advanced solutions, such as the Original Prusa XL, which features up to five independent print heads.

Original Prusa MMU3 Enclosed (for CORE One) - Conversion Kit
If you already own a combination of MK4S with the MMU3, and you wish to move the MMU3 to the Prusa CORE One, this package is for you. This kit comes with a top cover, so the printer will remain fully enclosed. Please note that you will need to disassemble the MK4S extruder to salvage parts that will be used in the CORE One’s extruder.
Important Nozzle Information
For the best performance (speed and efficiency with low waste) of the MMU3 unit on both the MK4/S and CORE One printers, we recommend using the standard nozzle instead of the high-flow variant. If you're ordering a standalone MMU3 for your MK4S or CORE One, we’ve got you covered: the MMU3 will come with a standard quick-swap nozzle included. For those purchasing the MK4S/CORE One and MMU3 together in a bundle, both nozzles will be provided. Additionally, if you opt for an assembled MK4S within an MMU3 bundle, it will have the standard nozzle already installed for your convenience.
Lite vs Enclosed Version Differences
The MMU3 for the Prusa CORE One is available in two distinct versions. In both cases, the hardware is the same: the MMU3 unit, the buffer and spoolholders. The Lite version is mounted on top of the printer with the printer’s top panel removed. This makes the installation quick and easy, however, you will lose the benefits of the fully enclosed printer (although you can 3D-print a new top cover). The Lite version is a good option for those who already have the MK4S with the MMU3 and are looking for the easiest and fastest swap between the two machines.
The Enclosed version comes with a new plastic part - a modified top cover with a pass-through for the PTFE tube that leads the filament from the MMU3 to the extruder. In this case, the printer remains fully enclosed.
