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.
SHIPS IN 1-2 WEEKS
The best large-format 3D printer with a 60 °C heated chamber.
Stop slicing, gluing, and assembling your large 3D prints. The Original Prusa CORE One L gives you double the print volume of the standard CORE One, adding a 60 °C heated chamber for warping-free printing. Plug-and-print simplicity, over 200 validated material profiles, and instant setup: the perfect, highly reliable manufacturing companion for your workshop.
Bypass the pitfalls that plague large printers. With the CORE One L, thinking about correct model placement is a thing of the past. Say goodbye to warped and twisted corners, and flawlessly print massive objects across the entire bed thanks to its state-of-the-art heat distribution.
The bed is what makes it possible
Anyone can take a heatbed and make it larger. Doing it properly is a completely different challenge. Large 3D-printed objects tend to warp, and when heat distribution is inconsistent, their corners lift off the bed. The CORE One L features a massive, heavy, all-aluminum heatbed with a dual-loop heating system and perfect heat distribution. No matter how big you print, the results are perfect.
Variance stays under 2 °C across 99% of the surface. The printer also automatically distinguishes between 110V and 230V grids and intelligently configures the heatbed for consistent performance in any part of the world, all protected by robust multi-layer security systems.
Replace metal with engineering polymers
The powerful heatbed with convection-style heating brings the chamber to 60 °C, an optimal, stable environment for advanced materials. Result: stronger layer bonding, no warping, tougher prints.
Add the HT Hotend Upgrade to print ultra-tough engineering polymers, like carbon-fiber reinforced PEKK-CF and PPS-CF, or high-performance PPSU and PPA-CF strong enough to replace metal parts.
The printer purchase is the biggest expense. After that, it's just filament and the occasional spare nozzle or print sheet. No vendor locks, no forced subscriptions, and free software and firmware upgrades for the life of the machine.

CORE One L Passes Security Audits
The CORE One L never requires a network connection. Configure the printer, slice models, and install firmware updates offline without sacrificing any features or performance. For environments requiring strict security, the Wi-Fi module can be physically removed.
Government agencies, high-clearance manufacturing, and companies handling sensitive data can operate with the absolute guarantee that the printer will never share a single byte of data with any cloud infrastructure.
Designed for facilities with strict security protocols, the Critical Infrastructure Bundle guarantees offline safety: zero Wi-Fi circuitry, no built-in cameras, and a certified, encrypted USB drive.
CoreXY uses two fixed motors in the corners that pull on a long, continuous loop of belts to move a tool head. Because the heavy motors are fixed in place, the gantry is incredibly light, allowing for blazing fast speeds and outstanding precision. Here's a proper tour of the engineering choices that set the CORE One L apart.
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, with travel speeds reaching 500 mm/s.
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. Nothing is glued together, nothing is welded – you can take everything apart with a screwdriver.
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 300×300×330 mm (30 liters) is waiting for your projects. Forget about cutting and gluing models – print them whole. (From left to right: CORE One+, CORE One L, MK4S.)
When you select a low-temperature material (e.g., PLA or PETG), the printer will automatically open the top vent using a lever on the extruder. For high-temperature materials, the vent is automatically closed.
A 1080p camera with night vision is included in the package, and you're free to choose whether to install it. You can use it to monitor your prints via Prusa Connect / Prusa App or to easily create timelapse videos.
For a truly safe workspace, you can install an optional Advanced Filtration Module with HEPA and Active Carbon filters, but you can also take the CORE One L and hook it up to an HVAC system.
Ready for 8 materials
The INDX upgrade is a revolutionary toolchanging system developed in collaboration with Bondtech. It lets you combine up to 8 different colors or materials in a single print, automatically switching between them in seconds with near-zero waste.
The fastest way from idea to 3D print
With most projects, you want a simple workflow. “I want to print this model from this material and with this quality.” EasyPrint is the fastest way to achieve that. It features a real online slicer engine and runs on your phone. Four taps and you're printing. If you get CAD files from your colleague, you can easily import them as well.
Free software, remote management, community models, and top-quality filament, all designed to work together.
Experience a printing platform designed with transparency, repairability, and your creative freedom in mind. You own your 3D printer, not just a license to use it.
CORE One L works with any standard 1.75 mm filament. Use Prusament for tested quality or pick your favorite brand. PrusaSlicer includes over 200 ready-made profiles, and you can always create your own for new materials.
Print via USB drive or your local network – no internet connection required. Optional Prusa Connect adds remote monitoring and print farm management. You don't have to connect the printer to the internet; not even once.
The firmware source code is on GitHub and CAD files are published at Printables.com. You can inspect, modify, or build your own version. No locked bootloaders, no cloud dependency. Prusa has been shipping open-source printers since 2012.
PrusaSlicer, EasyPrint, Prusa Connect, the Prusa App, and every firmware update – included with the printer and free. No forced ads, no hidden subscription tiers.
Nothing is glued. Everything comes apart with a screwdriver. Spare parts stay in stock for years after release. A worn nozzle (after hundreds of print hours) is a $20 swap, not a reason to worry.
Whenever it's even remotely possible, Prusa offers a clear and transparent upgrade path. When an improved model comes out, you can usually upgrade the printer you already have.
No self-tests, calibrations, or tinkering
The CORE One L is ready to print right after unpacking. It's incredibly easy to start printing. To truly appreciate and explore all the aspects of your new printer, a comprehensive Prusa Academy course on the CORE One L is included at no extra cost with every machine. This is perfect for 3D printing newcomers and in the educational sector, but it also makes onboarding new employees a breeze.
Factory-calibrated, including Input Shaper and Phase Stepping. Attach the display, pick a language, and you're printing.
Detachable – monitor prints and make timelapses, or leave it out entirely for maximum privacy.
A genuine 0.4 mm high-flow nozzle pre-mounted, plus a 0.4 mm abrasive-resistant nozzle for reinforced and filled materials.
A 1 kg spool of Prusament PLA, a satin powder-coated print sheet, alcohol wipes, and a full tool set with spare parts. (And, by tradition, a bag of Haribo gummi bears.)
A comprehensive online course on running, printing, and maintaining your machine – perfect for onboarding a team.
A printed 3D printing handbook and a USB drive with ready-to-print models to get you started.
CORE One L works perfectly out of the box. Still, you may want to consider these accessories to level up your 3D printing game.
