Summary

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.

Description

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

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 248×205×270 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.

The Innovations that Drive the INDX

Only 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.

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. By default, the INDX comes with high-flow 0.4 mm nozzles.

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.
