Product description: INDX 4-Tool Conversion Kit for Original Prusa CORE One/+ 3D printers
The INDX 4-Tool Conversion Kit for the Prusa CORE One/+ is an innovative tool-changing system that overcomes the limitations of typical single-nozzle multi-material solutions. Each tool has its own filament path and dedicated nozzle , enabling multi-color, multi-material printing, and the use of soluble supports without the need for large cleaning towers . The system utilizes an active Smart Head with inductive nozzle heating, ensuring fast tool changes and minimal material waste. The kit retains all the benefits of the CORE One/+ printer , including a closed chamber, high build speed, and integration with PrusaSlicer and Prusa Connect.

The kit retains all the benefits of the CORE One/+ printer, including a closed build chamber, high speed, and full integration with PrusaSlicer and Prusa Connect.
Main Features of the INDX 4-Tool Conversion Kit
- 4 independent printing tools - the ability to use four materials or colors simultaneously during one print
- Expandable to 8 tools - the system can be expanded with additional passive heads
- Induction nozzle heating - quickly reaches operating temperature without heaters in each tool
- Minimal waste - approximately 13 mg of filament when changing material
- No cleaning towers - almost full utilization of the work surface
- Multi-material support - compatible with PLA, PETG, ASA, ABS, PC, PCCF, PA, TPU, PVA and BVOH
- Dynamic Extruder DX - automatic adjustment of filament pressure
- Hardened CHT nozzles - high flow and abrasion resistance
- Closed build chamber - retains all CORE One+ printer functions
- Integration with PrusaSlicer and EasyPrint - easy preparation of multi-color models
Advanced tool changer for multi-material printing
The INDX utilizes independent tool technology, which allows each nozzle to have its own material path . This eliminates the problem of mixing materials and the need for frequent hotend cleaning when changing filaments. The system allows you to combine rigid, flexible, soluble, and technical materials in a single print . You can also use different nozzle diameters within a single project . With the ability to expand up to eight tools, the printer becomes an incredibly versatile production tool.

One of the biggest advantages of the INDX system is the almost complete elimination of waste generated during filament changes.
3D printing without material waste and cleaning towers
One of the greatest advantages of the INDX system is the near-complete elimination of waste generated during material changes . Instead of building large cleaning towers , the system removes only approximately 13 mg (0.013 g) of filament with each tool change . This significantly reduces operating costs and shortens the turnaround time for multi-color prints. Additionally, the Advanced Nozzle Wiper improves the quality of transitions between materials and reduces the risk of artifacts on the model. The result is cleaner prints with significantly less filament consumption.
Innovative technologies used in the INDX system
The heart of the system is the active Smart Head, equipped with a contactless induction coil that heats passive tools in seconds. This solution eliminates the need for complex electronics in each head and increases the reliability of the entire system. The Dynamic Extruder DX automatically adjusts the filament pressure to the material's properties , improving extrusion quality. A mechanical Maxwell clutch is responsible for precise tool loading and unloading. The entire system is designed for high durability and easy upgradeability.
EasyPrint and PrusaSlicer - quick preparation of multi-color models
The INDX system works with the free EasyPrint and PrusaSlicer tools , which significantly simplify the preparation of multi-material prints. You can easily assign colors and materials to selected model elements using intuitive painting tools. EasyPrint works directly in your web browser, while PrusaSlicer offers advanced features for demanding users. Pre-made printing profiles make setting up the process quick and easy, allowing you to start multi-material printing almost immediately after installing the kit.
