GoKawiilOne thousand Prusa CORE One INDX Founder’s Editions have shipped, giving a lucky few first access to Bondtech’s revolutionary toolchanger mod. The Founders Edition is a special limited run, intended for early adopters and Prusa fanatics.
The INDX toolchanger promises multi-material printing without the headache of prime towers and massive purge waste. Since toolchangers have a dedicated nozzle for each filament path, they don’t need to clean out the nozzle between color or material swaps; however, they do need to “prime” the nozzle to make sure the filament is flowing at the right pressure. Before the INDX, this meant printing a smallish, unavoidable prime tower. The INDX has been precisely tuned to purge only tiny crumbs of waste into an internal tray, then wipe the nozzle on a silicone pad.

The INDX, invented and patented by Bondtech, uses an induction heater to rapidly bring each nozzle to temperature in a few seconds. This allows the Prusa Core One with INDX to have some of the fastest color swap times we’ve seen.

Tom’s Hardware was sent an eight-tool kit so we could share our first-hand experience with the INDX. It took the better part of a weekend to strip down our existing CORE One and modify it. This involved completely removing the Nextruder, replacing it with the INDX carriage, then mounting a rack to hold the eight tool heads. Eight spool holders were mounted on the sides, using preexisting screw holes. A calibration sensor was mounted to the front corner of the build platform, and an internal waste catcher was installed.

Prusa requested that we not conduct a full review of the Founder’s Edition, as it is merely a taste of what’s to come. The final retail INDX will be a more refined version, with a few tweaks (like better visibility through the front grill) and firmware upgrades. Prusa Research is taking feedback from Founders to improve the retail launch.
Prusa Research is expected to launch the retail version of the INDX for Prusa CORE One + by the end of July. A 4 tool kit will cost $749, while an 8 tool kit will run $999. Bondtech is offering a Development Kit that can be installed on Vorons, Sovols, or whatever you can hack, with a starting price of $487.50 for one toolhead.
So why is the Founders Edition considered unfinished? Bondtech’s original INDX concept was designed as a generic add-on to any compatible 3D printer, not as a bespoke Prusa mod. We first saw a Bondtech demo of the INDX at Rapid/TCT in April of 2025, mounted on a Voron 0. The partnership with Prusa Research was announced seven months later at Formnext, with a functional CORE One sporting eight tool heads.
