    INDX 8-Tool Conversion Kit for CORE One L+

    Loading...

    Not compatible with

    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.

        INDX Conversion Kit for CORE One L+Combine up to eight filaments in a single print

        Each material is loaded into an individual toolhead, and the INDX Smart Head picks them as necessary to create beautiful, colorful objects fully automatically. It's extremely fast and highly efficient - each filament change produces waste the size of a grain of rice. And you keep the 60°C chamber for printing large objects without warping.

        The Best Material Combinations

        Go beyond mere colors and take your projects to the next level with material mixing!

        Easy Support Removal

        Easy Support Removal

        Print intricate internal cavities and overhangs using dedicated support materials. Use a different material for supports so they separate cleanly.

        Integrated Soft Grips

        Integrated Soft Grips

        Fuse flexible TPU directly onto rigid PETG or PLA tool handles during printing - eliminating secondary assembly and adhesives.

        Structural + Flexible

        Structural + Flexible

        Pair durable Polycarbonate enclosures with flexible TPU seals or compliant hinges for strong, functional parts.

        ColorMix Printing

        ColorMix Printing

        Blend five or even six filament spools to generate dozens of custom fullspectrum color shades without constant manual spool swaps.

        Choose from hundreds of materials

        The included nozzles are a perfect choice for materials like PLA, PETG, ASA, TPU, PolyCarbonate, PA11 Nylon, PVB, BVOH, and many others - essentially all non-abrasive materials.

        The nozzles are surface-hardened nitrocarburized steel; not designed for long-term printing with abrasive materials. They are rated for 10kg of PETG-CF, or 5kg PC-CF, or 0.5kg Prusament Ultraglow before print quality is affected.

        Free software, no PC required

        Paint any model in color, on your phone or tablet

        EasyPrint runs in a browser, so a phone or tablet is enough to prepare a print. Tap a surface, choose a color, and send it to the machine. When you want deeper control, use PrusaSlicer on Windows, Mac, or Linux. Both are free with the printer.

        Stop Wasting Filament!Cheaper solutions get expensive really quickly

        Waste generated during filament changes is the hidden cost nobody likes to talk about. The INDX generates only 0.013g of waste during material swaps - about a grain of rice.

        A 1kg spool of PLA filament costs 12-20 USD. Imagine throwing out almost the entire spool when you want to print an 80-gram model.

        What's in the conversion kit

        You can pick the 8-Tool kit or a 4-Tool kit (it can be later upgraded to 8 tools). In both cases, you will receive everything you need to install the kit, including a toolset and an easy-to-follow guide. The installation requires you to diassemble a part of your machine, remove the extruder and install the new parts. Users report it takes them about 5-6 hours.

        The CORE One L+ with the INDX upgrade installed has a print volume of 298×275×330mm.

        INDX Smart Head

        A brand-new dynamic extruder designed by Bondtech. Features an automatic tool picker, super-fast induction heating, and wireless temperature sensing.

        4 or 8 Passive Toolheads

        The toolheads are one of the best things on the INDX - they are entirely passive and feature no electronics. Simple, effective, and inexpensive design. Built-in 0.4mm nozzle.

        Tool Offset Sensor

        A state-of-the-art tool offset sensor ensures that all the colors are aligned perfectly. Your prints will look just as good as on the stock CORE One L.

        Wiper and waste bin

        A silicone wiper primes the nozzle so you don't need a leftover block of plastic next to the model. The leftover plastic drops into a waste bin.

        Choose Your INDX Configuration

        Decide how many nozzles you want. The number of tools can be the number of loaded materials or colors. Each tool can have a different nozzle. This makes the printer ready for every scenario.

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

        Printing with up to 8 materials may seem like a complex job. Here's how we made it so effortless.

        High‑Speed Nozzle Swapping in Just 12 Seconds

        Single-nozzle multi-material systems spend roughly 42 seconds on every single filament swap. They must retract, cut, feed, and flush the hotend, wasting time and plastic on every layer. The INDX toolchanger is much more efficient - requires merely 12s per change.

        indx head

        Cold in the Dock, Hot in Seconds

        The moving head carries an induction coil which heats the nozzle wirelessly in seconds. It grips a nozzle, brings it to working temperature nearly instantly, and lets it cool again the moment it parks, so it does not ooze.

        indx nozzle

        Active Head, Passive Toolchangers

        Each parked tool is a nozzle and a dock - no electronics. All the intelligence lives in the head that collects them, so adding four more tools is inexpensive - it's four passive nozzle instead of four active toolheads.

        first layer

        The nozzle measures the bed before every print

        The tip presses down on the sheet and a load cell reads the force, so the machine knows exactly where the bed is. This is much more precise than optical solutions, and you can switch nozzles and tools as much as you want without recalibrating the printer every time.

        Nozzle Wiper

        Advanced Nozzle Wiper

        The built-in two-way nozzle wiper is the key to beautiful prints and minimum waste. Every time a new tool is picked up, only a tiny fraction of plastic is extruded to stabilize the pressure in the nozzle. The nozzle is cleaned to prevent any stray blobs from contaminating the print.

        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 0.8. 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.

        offset sensor

        Automatic Tool Offset Calibration

        The state-of-the-art offset calibration system is permanently mounted outside the print area.
        20x Faster than calibration pin: It takes just 15 seconds per toolhead.
        Improved Repeatability: Streamlines setup while delivering highly consistent results.
