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 — 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.
No wipe tower, no piles of plastic around the printer
Water-soluble or break-away organic supports
Add a rubber-like grip to functional prints
Have all your favorite materials always loaded
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 achieves unbeatable results thanks to rapid induction heating of its nozzles. It doesn't waste time on wipe towers.
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. 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. 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.

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 — no huge purge structures, no large piles of filament "poop," and absolute minimum wasted material.

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 deposits a 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)
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.


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.
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.


Always Ready to Print
Load eight filaments, install different nozzle sizes from 0.25 to 0.8mm. 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.
Choose Your Kit
Both kits include the same Smart Head and docking hardware. The only difference is the number of passive tools. You can always add more later.

It's Easy with EasyPrint and PrusaSlicer
EasyPrint and PrusaSlicer are two free tools you can use to prepare any 3D model for printing. Both feature easy-to-use tools for virtual painting, so you can turn any model you download into a beautiful, color-rich 3D print. EasyPrint works in your browser or on your phone/tablet and PrusaSlicer is a fully featured software package for Windows, Mac and Linux.
Always Perfect First Layer
Even with multiple nozzles, the INDX achieves a beautiful first layer without lengthy calibration thanks to the LoadCell sensor. Simply hit Print and let the machine do the rest!


Works Perfectly with Prusa USS Drybox
INDX spoolholders are fully compatible with the Prusa USS Drybox and you can attach all eight of them. This way, you can keep your advanced, hygroscopic materials neatly stored and dry — and have them always ready for a new print job.
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 — you can optimize it, but you can't eliminate it.
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 "poops" require frequent management
- — Residual material causes color bleeding and contamination
- — TPU jams in shared hotends
- — Abrasive filaments wear brass nozzles in shared systems
- — Some systems locked to proprietary RFID filament chips
