Prusa CORE One INDX: The Game-Changing 8-Nozzle Toolchanger
Prusa Research and Bondtech opened orders on April 24, 2026 for the INDX system — a revolutionary toolchanger with up to 8 independent nozzles, induction heating, and almost zero waste. Desktop 3D printing has reached its most advanced level ever.
Prusa CORE One+ with the Bondtech INDX system — orders open since April 24, 2026.
What is the Bondtech INDX?
The INDX is no longer a filament-swapping system like the MMU or AMS. It is a new 3D printing architecture. Instead of pushing different filaments through the same nozzle, the INDX allows up to 8 passive print heads to be parked and ready to use simultaneously.
The magic happens in the active Smart Head (Smart Head), the only component with electronics. It moves, grabs the desired nozzle, and heats it instantly through magnetic induction — just like an induction cooktop. When the nozzle is parked, it cools in seconds, without plastic strings or clogs.
This is a collaboration between two leading European companies: Prusa Research (Czech Republic) and Bondtech (Sweden), world leaders in extrusion systems.

The 5 Major Advantages of the INDX System
⚡ Ultra-Fast Induction Heating
The Smart Head heats the nozzle from zero to printing temperature in seconds. No heater block, no oozing when parked.
♻ Zero Waste
Only 13 milligrams of filament wasted per tool change — less than a grain of rice. Say goodbye to purge towers and filament "poops"!
🧰 Unlimited Material Mixing
PLA + TPU supports, PETG + PVA soluble supports, carbon fiber + regular materials — all in the same part, without clogs.
🔍 Different Nozzle Sizes
0.25 mm for fine details and 0.8 mm for fast infill in the same print. Compatible with nozzles from 0.25 to 1.0 mm.
🤖 Auto-Adjusting DX Extruder
The drive gear automatically adjusts the force depending on the material — from super soft TPU to Carbon Fiber Nylon.
🎯 20× Faster Calibration
New calibration system using eddy currents outside the print area. 15 seconds per nozzle, instead of hundreds of seconds on the XL.
The INDX 8-tool kit — 8 loaded spools, 8 materials ready to print simultaneously.
INDX vs. Traditional Single-Nozzle Systems
❌ Single-Nozzle Systems (MMU / AMS)
- You have to purge the old material before each change
- The purge tower can weigh more than the part itself
- Cross-contamination between materials
- TPU clogs shared hotends
- Impossible to use different nozzle sizes
- Limited to filaments with proprietary RFID chips (in some cases)
✅ INDX Toolchanger
- Each nozzle has its own path — no purging
- Almost zero waste (13 mg per tool change)
- No cross-contamination between materials
- TPU, PVA, Carbon Fiber, and PETG in the same part
- Nozzles from 0.25 to 1.0 mm in the same print
- Compatible with any 1.75 mm filament
Prices and Available Configurations
The INDX is sold as a conversion kit for those who already have the Prusa CORE One+. There are two versions available for order directly on the Prusa website:
| Version | What's Included | Price |
|---|---|---|
| INDX 4-Tool Kit | Smart Head + 4 passive tools (0.4 mm hardened CHT nozzles) + mounting hardware + spool holders | ~€669 / $699 |
| INDX 8-Tool Kit | Smart Head + 8 passive tools (0.4 mm hardened CHT nozzles) + mounting hardware + spool holders | ~€899 / $899 |
The 4-tool kit is the entry-level version — you can always add 4 more nozzles later.

Is It Worth the Investment?
If you frequently print in multiple colors or materials, the INDX pays for itself over time. On complex parts, the filament waste in a conventional system can easily exceed the weight of the part itself — and with the INDX, that problem completely disappears.
In addition, the ability to use water-soluble supports (PVA/BVOH) or easily removable TPU supports opens doors to engineering designs that would be impossible — or a nightmare of clogs — on a single-nozzle system.
Prusa and Bondtech have just raised the bar for desktop 3D printing to a truly professional level. The "endgame" of 3D printing has arrived.
