Prototyping & Art
From architectural scale models to movie-grade prop making and cosplay design, the CORE One L+ allows top creators and engineering firms to print highly detailed scale prototypes in a single part.
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. Learn more about the CORE One L+ here.
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.
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.
Print intricate internal cavities and overhangs using dedicated support materials. Use a different material for supports so they separate cleanly.
Fuse flexible TPU directly onto rigid PETG or PLA tool handles during printing - eliminating secondary assembly and adhesives.
Pair durable Polycarbonate enclosures with flexible TPU seals or compliant hinges for strong, functional parts.
Blend five or even six filament spools to generate dozens of custom fullspectrum color shades without constant manual spool swaps.
Prints just as beautifully as the stock CORE One L+, edge to edge
About 12 seconds per material change - fastest on the market
Produces the least amount of waste, bar none
Ultra-fast induction heating and rock-solid toolchanger
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.
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.
Seamlessly Integrated
You are getting the exact same CoreXY 3D printer, but with the INDX system installed and calibrated at the factory. It uses the same heavy-duty frame, the same linear rails, and the same electronics that are already running 24/7 in print farms worldwide.
Printing with multiple materials is just as easy as printing with one
No lengthy assembly and tinkering. Attach accessories and let the welcome wizard guide you. The printer arrives factory-calibrated.
Open the app and browse more than a million free designs. Find something you like and send it straight to the printer.
The printer does the rest - automatic calibration, tool offsets, and print monitoring.
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.
Same printer, same performance. Decide how many nozzles you want on day one. CORE One L+ INDX ships fully assembled only - there is no kit. Looking for accessories? They are just below.

A universal satin sheet is in the box. See other print sheets if you need support for specific advanced materials.
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.
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.
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.
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!
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!

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.
These reviews are of CORE One L, not INDX. The foundation is the same: 30-liter enclosed CoreXY, 60 °C chamber, AC convection heatbed. INDX is the factory-installed toolchanger on that chassis.
Reliable, easy to use, capable of delivering great prints over and over: Prusa's newest system is made for production runs. (...) Although the competition is fierce, Prusa printers possess a unique quality that extends beyond their exceptional print quality and dependability.
VoxelMatters
I printed large models on the CORE One L that easily stayed stuck in place all the way out to the edges, a feat many large printers struggle with. And with its built-in Wi-Fi, you can send prints to your CORE One L from anywhere on almost any device, using the new EasyPrint feature on Printables.

Pick PLA or PETG, and the printer opens the top vent for perfect print results. Pick a high-temperature material, and the vent closes to hold 60 °C in the chamber, preventing large models from warping.
A 1080p camera with night vision is in the box. Install it if you want to record timelapses or monitor your printer from anywhere in the world.
The chamber exhaust can take the optional Advanced Filtration module (HEPA + carbon) or a duct into building HVAC. Useful when you print ASA in a lived-in room or a shop that already has extraction.
Printing with up to 8 materials is a complex job. Here is how we made it effortless, on a printer that already handles large, high-temperature parts.
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.
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.
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 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.
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.
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.
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.
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.

We believe that no matter whether you’re developing a new-generation space shuttle, or just printing toys for your kids, no organization should be interested in gathering information about your prints or your printer’s surroundings.
Consumable parts, such as print sheets (smooth, textured, etc.), are not covered by the warranty since their coatings are expected to deteriorate over time, unless the failure is due to a defect in materials or workmanship. Cosmetic damage, which includes, but is not limited to, scratches, dents, cracks, or other aesthetic damage, is also not covered. Only sheets defective upon delivery are covered by the warranty.
