Prusa Core One INDX Update: 8-Material Toolchanger Now Shipping with Major Waste Reduction

INDX Founders Edition Shipping, Standard Kits Next

Prusa Research and Bondtech have announced that the INDX Founders Edition — an 8-material multi-tool upgrade system for the Prusa CORE One 3D printer — is now shipping to early adopters. With that milestone behind them, the companies are moving to the next phase: shipping the standard INDX Conversion Kit for CORE One/+.

The first standard units are scheduled to leave the factory by the end of July 2026, with the entire first batch expected to ship by the end of August. The first batch of CORE One INDX kits previously sold out in just 1.5 days, underscoring strong demand for tool-changing capability in the consumer market.

Pricing and Configuration

The INDX conversion kit is available in two configurations: a 4-tool kit for $749 and an 8-tool kit for $999. By default, the kit ships with hardened high-flow 0.4mm nozzles, with other nozzle diameters available for purchase separately. The printer itself (CORE One or CORE One+) is sold separately at $1,100 for the kit or $1,449 assembled.

Major Improvements Since Launch

Since the initial announcement, Prusa and Bondtech have focused on several key improvements:

• New Docking Panel: A less dense front panel offering a better view of parked tools and the printer interior.
• Waste Bin with Silicone Nozzle Cleaner: A waste collection system that also cleans nozzles between tool changes, keeping them in optimal condition for each print.
• Automatic Tool Offset Calibration: A Tool Offset Sensor that measures each toolhead's offset with absolute precision using loadcell, inductive, and X/Y axis scanning — running automatically at every print start.
• ColorMix Support: Integration with PrusaSlicer and EasyPrint for halftoning-based color mixing, supporting up to CMYKW+RGB with the 8-tool setup.

Dramatic Waste Reduction

Prusa put five different 3D printers to the test using a typical multi-color model weighing 81.7 grams. The results were striking: while some solutions produced as much as 696.4g of waste (nearly an entire spool), the INDX produced only 29g of waste — nearly 30 times less. For a rocket engine model, the most wasteful solution generated 842g of waste compared to INDX's minimal output.

The waste reduction is achieved through a priming pellet system that deposits incredibly tiny amounts of material — averaging just 0.013-0.015g per prime — rather than traditional purge towers.

Software and Firmware Updates

Prusa has also released firmware version 6.6.1 for the INDX system, along with major updates to EasyPrint and PrusaSlicer that completely reworked color handling. The ColorMix Shading web app allows users to create unique effects using virtual lights and baked-in shading.

What's Next

Looking ahead, Prusa is working on additional print profiles for PrusaSlicer, a larger waste bin solution, and continued refinement of the INDX experience. Community demand for a Core One L version is high, though no specific timeline has been confirmed yet.
