Bondtech INDX for CORE One+Eight nozzles. True multi‑material. Virtually zero waste.

The INDX is an extremely fast, highly efficient toolchanger system with up to eight independent toolheads that seamlessly integrates with your CORE One+ 3D printer. Each material gets its own dedicated path, so you can combine rigid and flexible parts, use easy-to-remove or dissolvable supports, switch nozzle sizes in the same print, and print multi-color models without throwing half of the spool to waste.

What can you achieve with 8 nozzles?

Multi-material goes beyond color. It lets you build functional parts that combine properties no single filament can deliver.

Multi‑color without the usual mess

No wipe tower, no piles of plastic around the printer

Supports that are easier to remove

Water-soluble or break-away organic supports

Rigid + Flexible in One Print

Add a rubber-like grip to functional prints

Different nozzle sizes always at the ready

Have all your favorite materials always loaded

CONVERSION KIT

You already own half of it

If you already have a CORE One+ 3D printer, the INDX is a conversion kit, not a new machine. Install the Smart Head, mount the tool docks, load your filaments. Your existing print sheets, filament collection, PrusaSlicer profiles, and Prusa Connect setup carry over unchanged. Same printer, dramatically more capability.

Lightning-Fast Toolchanger

Keep all the features of your CORE One+, like high-speed printing and a smart ventilation system, and give it a massive boost with this extremely fast tool-changing system. The INDX toolchanger achieves unbeatable results thanks to rapid induction heating of its nozzles. It doesn't waste time on wipe towers. Only with the INDX, you'll get beautiful, multi-material 3D prints faster than ever before - and with all the benefits only a toolchanger can provide.

Real Performance Metric

True Toolchange Time: ~12 seconds per change

We measure toolchange time from the last extrusion on one material to the first extrusion on the next, on the model itself. This avoids inflated and misleading numbers based on partial steps. The ~12 seconds per change for PLA is the time between when one nozzle leaves the printed part until the second nozzle starts printing.

Three Major Benefits for Better 3D Printing

No Wipe Towers / Purge Blocks

Nearly all multi-material systems place a block in the corner of your print sheet where the nozzle purges excess filament. The INDX doesn't do that. You can use up to 248×204×270 mm for your prints!

Doors Closed, at All Times

Many enclosed printers require you to keep the chamber door open when printing PLA or PETG, eliminating the benefits of the closed chamber. The INDX retains the unique ventilation system, so you can keep the doors closed.

Use Any Filament You Want

The INDX is not limited by storage options or proprietary RFID chips. You are completely free to use any spool you like, including all the materials you already know and love.

Stop Wasting Filament!Cheaper solutions get expensive really quick

INDX Does Not Create Excessive Waste

This is how multi-material should be done.

Nearly every multi-material solution on the market produces excessive plastic waste during filament changes. A cheaper machine might save you money on day one, but you'll pay the difference in wasted filament by month six.

When INDX swaps materials, it purges around 13 milligrams of plastic (0.013g) to stabilize the pressure inside the nozzle. That means no huge purge structures, no large piles of filament “poop,” and absolute minimum wasted material across long and complex prints. The INDX produces 5× less waste than the most efficient systems and 30× less than standard filament rewinding systems.

new level of reliability

Advanced Nozzle Wiper

Zero attention required even during long print jobs

The advanced nozzle wiper for induction nozzles helps remove any residue left on the nozzle before printing resumes, improving cleanliness during swaps and reducing the risk of stray blobs affecting print quality. The nozzle wiper is located on a purge collector, where the nozzle deposits the micro-blob of plastic, smaller than a grain of rice.

This is all the waste INDX generates during filament change!

Less than a grain of rice (13 milligrams)

The Innovations that Drive the INDXOnly one active component - less complexity, lower price, easier to use.

Smart Active Head

Fast Induction Heating

The INDX Smart Head contains an induction coil - just like an induction cooktop. When it picks up a toolhead, it generates a high-frequency magnetic field that heats the nozzle from cold to printing temperature in seconds. When the tool is parked, it cools rapidly. No oozing, no stringing from idle nozzles.

Hardened high-flow nozzles

Passive Toolheads

Using passive tools without any electronics is a massive advantage: they are less complex and more reliable. Adding a fifth, sixth, or eighth tool means adding a nozzle and a parking dock - not another full print head. The standard nozzle is a hardened 0.4mm CHT (high flow) - the ultimate combo.

The Dynamic Extruder

Self‑adjusting grip for different materials

Soft materials need a gentler grip than rigid, fiber-filled ones. The INDX features a unique mechanism that adjusts the drive gear tension automatically, so you can move from TPU to rigid engineering filaments without stopping to retune the extruder.

8 materials conveniently loaded

Always Ready to Print

Load eight filaments, install different nozzle sizes from 0.25 to 0.8. When you start a print, everything's already ready and loaded. Just pick the right tool. If you like to use different filaments and nozzles, and hate constantly swapping everything around, the INDX is the solution for you.

Effortless Start

Start Printing in No Time

Once you install the INDX, the printer will perform a quick calibration, so it can pick up and park all eight tools with absolute precision.

The INDX conversion kit doesn't have the same bed-mounted calibration pin as the Prusa XL. Instead, there is a new toolhead offset calibration system, permanently mounted outside the print area. - Dual-Target Precision: Uses a secondary target to actively cancel background noise, ensuring highly precise sensor readings in any environment. - 20x Faster: Calibration takes just 15 seconds per toolhead - down from hundreds of seconds on the stock XL. - Improved Repeatability: Streamlines setup while delivering highly consistent results.

One nozzle is a limit

Why single-nozzle multi-material has a ceiling

Shared Melt Zone

Every single-nozzle multi-material system has the same fundamental problem: one melt zone for multiple materials. Every color change means unloading the old filament, loading the new one, and purging everything in between.

Expensive Waste

On complex prints, the waste usually weighs more than the finished object. That's a physical limitation baked into the architecture, not a design choice. You can optimize it, but you can't eliminate it. Even with cheap filaments, you are effectively throwing away your money.

Trouble with Mixing Materials

You can't combine materials that create an incompatible environment in the nozzle. Try running TPU through the same hotend as PLA and watch the jams pile up. Different nozzle sizes in one print? Impossible with only one nozzle.

INDX Toolchanger

  • Each tool has its own nozzle, no need to purge
  • Virtually zero waste, no wipe towers or filament "poop"
  • No cross-contamination between materials
  • TPU, PVA, Carbon Fiber and PETG in one print
  • Hardened nozzles by default handle any abrasive filament
  • Works with any filament brand, any spool size

Single‑Nozzle Systems

  • Single nozzle must purge old material before loading new
  • Purge tower can weigh more than the finished print, large filament "poops" require frequent management
  • Residual material causes color bleeding and contamination
  • TPU jams in shared hotends
  • Abrasive filaments wear brass nozzles in shared systems
  • Space limitations, some systems lack profiles for filaments without proprietary RFID chips
