BondTech INDX Tool Conversion Kit for CORE One/+ (Gen 2), 4 Tool Kit

Bondtech INDX Tool Conversion Kit for CORE One+ (Gen 2) upgrades an existing Prusa CORE One/+ (Gen 2) into a fully fledged tool-changing system. Each material has its own dedicated path, making it possible to combine rigid and flexible parts, use soluble support materials and print multicolour models without wasting most of the spool as purge material. The kit is available in either a 4-tool or 8-tool configuration to suit your setup; both use the same Smart Head and docking hardware and can be expanded at any time.

► 4-tool or 8-tool: which version is right for you?

The 4-tool kit is ideal for getting started with multi-material printing without committing to the full configuration straight away. The mounting plate is already prepared for four additional tool positions, allowing the system to be expanded to eight tools at any time. The 8-tool kit provides the full range of material options from the outset.

Both versions use the same Smart Head and docking station components and differ only in the number of passive toolheads and spool holders supplied.

One active head, multiple passive tools

At the heart of the system is the INDX Smart Head developed by Bondtech: an active extruder with an automatic tool pickup mechanism, rapid induction heating and contactless temperature measurement. The individual toolheads themselves are completely passive and contain no electronics of their own. This keeps the system simple and robust, while also making it comparatively inexpensive to expand from four to eight tools later on, as only passive nozzles need to be added rather than complete active toolheads.

Material changes in around 12 seconds

While some single-nozzle multi-material systems can take around 42 seconds to change filament, INDX completes a tool change in approximately 12 seconds. When printing multicolour or multi-material models, this means noticeably less waiting time and virtually no wasted filament, with no need for a conventional purge tower that would otherwise take up valuable build volume.

Induction heating instead of slow heat-up times

The moving Smart Head contains an induction coil that heats the nozzle of the selected tool to operating temperature contactlessly and within seconds. As soon as the tool is returned to its dock, it cools down quickly, helping to prevent material from oozing from the nozzle.

Automatic tool calibration

A tool-offset sensor mounted permanently outside the print area automatically calibrates the alignment of all toolheads relative to one another. The process takes only around 15 seconds per toolhead, making it significantly faster than conventional calibration using a mechanical pin while also providing greater repeatability.

Self-adjusting filament grip

Soft materials such as TPU require a different level of pressure from rigid, fibre-reinforced filaments. The system's Dynamic Dual Drive automatically adjusts the drive tension to suit the material, allowing users to switch between flexible and engineering filaments without manually readjusting the extruder.

Material compatibility up to 300 °C

The standard High Flow nozzles are made from surface-hardened, nitrocarburised steel and are suitable for PLA, PETG, ASA, ABS, PC, PA, TPU, PVA, BVOH and other non-abrasive materials at nozzle temperatures of up to 300 °C. They are not designed for continuous use with abrasive filaments.

Enclosed chamber remains fully available

The enclosed build chamber of the CORE One+ (Gen 2), with chamber temperatures of up to 55 °C, remains fully functional with INDX installed, including the intelligent ventilation system. The docking station and wiper reduce the build volume by around 2 mm on the X axis and 15 mm on the Y axis, resulting in a build volume of 248 x 205 x 270 mm.

Included:

• 1 x INDX Smart Head
• 4 or 8 x passive toolheads (depending on kit version)
• 4 or 8 x spool holders (depending on kit version)
• 1 x nozzle wiper for induction-heated nozzles incl. waste container
• new plastic components & Top Cover
• mounting hardware & other accessories
• 1 x manual with online assembly instructions

Note: The nozzles currently supplied are surface-hardened rather than through-hardened and are therefore not intended for regular use with highly abrasive filaments such as glow-in-the-dark materials or heavily filled composites. Compatible materials include PLA, PETG, ABS, ASA, TPU, PC, PA (nylon), PVA, BVOH and other non-abrasive materials.
