Prusa CORE One+ INDX Is an 8-Tool 3D Printer That Leaves Single-Nozzle Systems Behind

What the INDX actually changes

The Original Prusa CORE One+ INDX 8-Tool is not another incremental multicolor upgrade. It replaces the entire single-nozzle switching approach with four independent toolheads that swap in about 5 seconds. No retraction purge, no wasted filament, no waiting for one nozzle to heat back up after a color change.

In testing, that architecture translated to a 14-dragon multicolor print finishing in about 27 hours. A comparable single-nozzle system running the same job took roughly 80 hours. The difference comes from eliminating the purge block between colors. Instead of forcing one hot end to spit out old material before the new color starts, the CORE One+ simply parks one toolhead and picks up the next pre-heated one.

Prusa partnered with Bondtech on the INDX system. The result is a machine that feels more like a production tool than a hobbyist experiment. Early firmware updates fixed initial calibration quirks, and after three weeks of continuous printing in one review unit, there was not a single missed layer or failed color swap.

Materials you can actually mix

Four independent toolheads open combinations that single-nozzle printers cannot manage. PLA and TPU in the same print is straightforward: rigid structure in one head, flexible grips in another, no chemical bonding between them. PETG supports and PLA main body is another practical pairing, because the supports snap away cleanly instead of fusing to the part.

Optional $150 top cover lets the printer run ABS and ASA without warping. Test brackets printed in ASA showed perfect dimensional accuracy and no layer separation. That is a big jump from what a $899 machine could handle even a year ago.

The software and workflow

The CORE One+ runs Klipper firmware with Snapmaker Orca, a customized Orca Slicer build. The interface is familiar to anyone who has used Bambu Studio or PrusaSlicer. All calibration is automatic: bed leveling via eddy-current sensor, vibration compensation in minutes, and the four toolheads align themselves without manual tweaking.

Full Spectrum Printing deserves attention. The system alternates 0.2mm layers of different colors to create blended hues the eye perceives as a new shade. Four base colors produce ten visible combinations, which means the palette is wider than the four spools suggest.

Value against the competition

At $2,249 assembled, the CORE One+ INDX undercuts most professional toolchangers. The Prusa XL with a multi-material upgrade costs more. The Bambu Lab H2C handles multicolor fast, but it still relies on single-nozzle purging. In direct comparison, the INDX printed 27 dragons to the H2C's 15 over the same period, with less waste and shorter elapsed time.

The upgrade path matters too. Existing CORE One or CORE One+ owners can buy an 8-toolhead kit for $999. That puts a mature toolchanging platform within reach of users who already invested in the base printer.

Who should buy it

This is the multicolor printer for makers who are tired of purge waste. It is for designers who need rigid and flexible materials in a single prototype. It is for anyone running a small print farm who wants to cut material costs and increase throughput without buying an industrial system.

The CORE One+ INDX ships with four 500g sample spools and ships October 15. It is already the most capable consumer multicolor machine available, and the price makes it hard to recommend waiting.
