BondTech INDX Tool Conversion Kit for CORE One/+, 4 Tool Kit

With the Bondtech INDX Tool Conversion Kit, your Prusa CORE One+ can be upgraded into a fully fledged tool changer with up to eight independent print heads. No new printer, no compromises on build volume and none of the filament waste produced by other multi-material systems. Your existing print sheets, profiles and Prusa Connect settings remain exactly as they are. It is the same printer, just with significantly more possibilities.

Which version is right for you?

Both kits contain the same Smart Head and the same docking hardware. The only difference is the number of passive toolheads and spool holders included. It can be upgraded at any time later on, should several toolheads be required after all.

► INDX 4-Tool Kit: 4 passive tools with hardened 0.4 mm CHT nozzles and 4 spool holders. The mounting plate is already prepared for four additional tool positions. Perfect for getting started with multi-material printing.

► INDX 8-Tool Kit: 8 passive tools with hardened 0.4 mm CHT nozzles and 8 spool holders. Full 8-material power from the very first print. Ideal for anyone who wants to go all in from the start.

Ultra-fast tool changer

All the strengths of your CORE One+ are retained: high-speed printing, an intelligent ventilation system and the enclosed chamber. INDX simply takes things a step further. Thanks to inductive nozzle heating, the system changes tools in fractions of a second without losing time on purge towers. The result: clean multi-material prints, faster than you would expect from conventional systems, with all the benefits that only a true tool changer can offer.

Short toolhead change time

With INDX, change times are measured where it really matters: from the moment one nozzle completes the final line on the part to the moment the next nozzle continues printing.

Three clear advantages that improve your 3D printing

► No purge towers, no purge blocks: Most multi-material systems use part of the print bed for a purge block where excess filament is deposited. With INDX, there is no such thing. The full build volume of up to 250 x 204 x 270 mm can actually be used for your models.

► The print chamber stays closed: With many enclosed printers, the door has to remain open when printing with PLA or PETG. INDX retains the clever ventilation system of your CORE One+, allowing the doors to stay closed during printing.

►Complete filament freedom: No proprietary spools, no RFID chips, no manufacturer lock-in. Any spool and any material you already know and trust can be used.

INDX does not waste filament

With INDX, there are no huge purge structures, no piles of filament scraps and material loss is kept to an absolute minimum. Compared with other solutions, INDX produces around five times less waste than other systems on the market and around 30 times less than conventional filament rewinding systems.

Advanced nozzle wiper

Low material consumption is only the beginning. The advanced nozzle wiper for induction nozzles reliably removes any residue from the nozzle before printing continues. This keeps tool changes clean and prevents individual droplets from spoiling the print result. The wiper sits on a purge collector, where the tiny micro-droplet, which is smaller than a grain of rice, is neatly deposited.

The innovations in the INDX

► Fast induction heating in the Smart Head: The INDX Smart Head uses an induction coil, similar to an induction hob. As soon as it picks up a tool, it generates a high-frequency magnetic field and brings the nozzle from room temperature to printing temperature within just a few seconds. When the print head is parked, it cools down just as quickly.

► Passive toolheads: All additional tools are completely electronics-free. This makes them more reliable, more durable and more affordable. Adding a fifth, sixth or eighth toolhead simply means adding an extra nozzle and a parking position, not an entire new print head.

► Dynamic Dual Drive (DX) Extruder with self-adjusting grip: Soft filaments need a gentler grip than rigid or fibre-reinforced materials. The DX Extruder automatically adjusts the tension of the drive gears, whether TPU is being printed or the next tool is switching straight to a technical filament.

► Up to 8 materials permanently loaded: Simply load several filaments and combine different nozzle sizes from 0.25 to 0.8 mm. For the next print, everything is already loaded and ready to use. All that remains is to select the right toolhead.

The difference compared with single-nozzle systems

In every conventional multi-material system with only one nozzle, all filaments share the same melt zone. With INDX, each material has its own dedicated path. In practical terms, this means:

• each toolhead has its own nozzle; no purging, no filament poop,
• no cross-contamination between materials,
• TPU, PVA, carbon fibre and PETG can be combined in a single print,
• standard hardened CHT nozzles are also suitable for abrasive filaments,
• compatible with every filament brand and every spool size.

Effortless start

The INDX configuration includes a small electronics board that is mounted next to the heated bed. After installation, the printer performs a quick calibration and can then pick up and park all tools with absolute precision. Simply get started, and the rest happens automatically.
