Prusa 3D-Drucker CORE One L+ INDX 4-Tool

The Prusa CORE One L is the larger sibling of the proven Prusa CORE One with DOUBLE the print volume! Easy to set up and built to last, this rugged machine is perfect for any workshop or business. Unpack & Print. Designed and manufactured in the EU.

Beautiful Results - Fast and Simple

From striking visual prototypes to functional tools with integrated TPU grips. The CORE One L+ INDX handles advanced multi-material printing on a large all-aluminum heatbed, so you can focus on the design and enjoy finished models with stunning surface quality.

Jigs, housings, and replacements in one go

One piece instead of glued parts. Shop fixtures and spares that fill the bed edge to edge.

CORE One L+ INDX Specifications

True multi-tool capabilities inside a large enclosed 3D printer.

It's the proven Prusa CORE One L+ with 27 liters of print volume, a 60 °C chamber, and an AC convection heatbed - enhanced with Bondtech's super-fast toolchanger. It's the simplest, most reliable way to print with up to 8 materials at this size. New GT1.5 belts for smoother surfaces are already installed.

Dedicated nozzles practically eliminate color flushing. You waste a microscopic 0.013g of material per toolchange. Prints are fast, precise, and dimensionally accurate right out of the box. Plus, you are never locked in. You can use any standard, affordable filament.

A massive 298 × 275 × 330 mm build volume in a compact footprint. The 60 °C chamber prints large ASA, PC, and Nylon parts without warping. Active ventilation stops PLA heat creep, and the heatbed stays perfectly uniform right to the edges.

Built for demanding workshops and print farms. It relies on a rigid steel exoskeleton and aluminum panels. Nothing is glued together. You can service the entire printer yourself using just a screwdriver, and we keep all replacement parts in stock.

You own the machine, not a software license. Run it entirely offline or connect to an open ecosystem - it is completely up to you. For absolute privacy, you can physically unplug and remove both the Wi-Fi module and the included 1080p camera.

The Best Material Combinations

Go beyond mere colors. Mix materials on parts large enough to ship as the final product - and with perfect surface quality thanks to the new GT1.5 belts.

Stop Wasting Filament!

Cheaper solutions get expensive really quick

Every time a shared-nozzle printer swaps filament, it must extrude a large volume of plastic into a purge tower to clear out the old color. This waste block steals valuable printable bed space and easily consumes up to 30-50% of your spool on complex multicolor prints. With the INDX, you avoid all of this.

Even heat across the whole bed

The all-new, all-aluminum heatbed with dual-loop heating provides beautifully uniform heat distribution, killing warping and cold corners. The printer automatically distinguishes between 110V and 230V grids and intelligently configures the heatbed for consistent performance in any part of the world. Everything is protected by robust multi-layer security systems.

The enclosure reaches up to 60 °C

Two fans on the underside of the heatbed create a convection effect - they bring cold air in and blast it across the massive heated surface to quickly bring the chamber all the way up to 60 °C.

Fast motion, fully enclosed

The advanced CoreXY motion system moves the lightweight printing head instead of the heavy base, allowing for much higher speeds without losing quality. Input Shaper firmware compensates vibration at high speeds, and the printer is beautifully fast with any filament - not just specialized high-speed options.

Steel frame, aluminum panels

The robust exoskeleton from the CORE One+ has been reworked: it's still incredibly sturdy, but thanks to aluminum panels, the printer is actually lighter than the CORE One+ even though it offers two times the print volume. It's the perfect companion for your work desk!

Twice the volume, almost the same desk space

Compared to the CORE One+, the CORE One L has only a slightly larger footprint; however, its print volume is twice as much. A massive 298×275×330mm (27 liters) is waiting for your projects. Forget about cutting and gluing models - print them whole!

Open files, yours to repair

CAD files for the CORE One L are published. Firmware source code is on GitHub. You can inspect, modify, or compile your own version. No locked bootloaders, no cloud dependency. We've been shipping open-source printers since 2012.

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.

Cold in the Dock, Hot in Seconds

The moving head carries an induction coil for nearly-instant nozzle heating. It grips a nozzle, brings it to printing temperature in seconds, and lets it cool again the moment it parks to prevent oozing.

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 a fifth or eighth material costs a nozzle rather than a whole print head.

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.

Advanced Nozzle Wiper

The advanced nozzle wiper is the key to low waste. Every time a tool is picked, only a tiny grain of plastic is pushed out of the nozzle to stabilize the pressure. The nozzle wiper is located on a purge collector, where the nozzle deposits the micro-blob of plastic, smaller than a grain of rice.

Self‑adjusting grip for different materials

Soft materials need a gentler grip than others. 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.

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.
