Huge print volume, active heat circulation, and more!

The CORE One L is much more than just a larger CORE One. We didn't just scale it up; we took everything that worked great and added features for effortless large-format printing.

For the body, we have chosen an effective combination of a solid steel frame and aluminum panels to create a lightened version of our proven exoskeleton design. And the results are compelling: the machine’s outside dimensions are only 10% larger than the CORE One, yet it maintains the same weight, and the print volume is doubled!

The standard heatbed has been replaced with our new AC convection heatbed with active air circulation for flawless heat distribution in the chamber. The printer comes with a detachable 1080p camera with night vision, two nozzles in the package, fully automatic chamber temperature management, easier FLEX filament feeding, and much more.

This machine covers everything: from ambitious hobby projects to highly demanding manufacturing!

Think Big. Print Big.

The 300×300×330 mm print volume (CORE One’s volume doubled) is the sweet spot for any kind of project. It lets you print large functional parts, production fixtures, architectural models, full-size cosplay helmets,
      and other massive objects all in one piece. And the best part? The new heatbed has the best heat distribution possible thanks to the materials used, so you can effortlessly print from edge to edge.

New AC Heatbed with Convection Heating

The new massive AC heatbed is made of a thick block of aluminum for the best possible heat distribution. This results in perfectly uniform heat distribution from edge to edge - no cold spots, no cold corners. You can place your model anywhere in the print area without worrying about lifted corners or warping. 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.

Unpack and Print!

Unpack the printer, click the display in place, and plug it in, all in five minutes. That’s it. No self-tests, calibrations, or tinkering. The machine manages everything on its own, including setting up the best print environment inside the chamber. Simply download something cool from Printables.com, process it with EasyPrint, and see it being printed instantly.

Start and Forget Machine

A larger build volume isn't just for big prints - it's for more prints. The Prusa CORE One L is the perfect machine for overnight jobs or large-series production. The print plate is 63% larger than the one in the CORE One, so you can fit significantly more objects on the bed and let it run overnight. You can always check the progress with a 1080p night vision camera, and get notifications on your phone.

Flawless Precision

You can be sure that with our internally developed, quality-focused print profiles, your models will turn out exactly how they were designed, with perfect dimensional accuracy as proven by CT scans. CORE One L utilizes the proven Nextruder with 360° cooling for flawless printing of 75° overhangs, saving both time and material.

Best Surface Quality

With the latest updates to PrusaSlicer and our internally-tuned print profiles, your prints will look better than ever. We have all but eliminated VFAs (Vertical Fine Artifacts) and ugly vertical stripes on 3D prints. What you pick up from the heatbed can be easily used as the final product you’ll ship to your customers.

Maximum Speed without a Catch

Don’t limit your projects to a small selection of specialized “high-speed” filaments. Use any PLA, PETG, or many advanced materials. The CORE One series represents our fastest printers yet: robust CoreXY kinematics, high-flow nozzle, Input Shaper, factory-tuned print profiles for 200+ filaments - it’s all there. However, we never sacrifice print quality to chase speed records. The prints are always solid, durable, and won’t crumble in your hand.

Effortless Printing with Advanced Materials

The chamber is as compact as possible, and with the new active heat circulation provided by a new high-performance heatbed with two fans, it heats up to 60°C in record time. This way, you can easily print advanced materials like ASA, ABS, PC, PA (Nylons), and many more. And the results will be amazing: no cracks, no lifted corners, no warping.

A Proper FLEX! New option for inserting flexible filaments

The side filament sensor can be toggled to flexible filament loading mode using a physical switch - this disables the filament sensor and opens a wider, less restrictive way for flexible materials. However, a second filament sensor in the print head still monitors the filament runout.

Robust Steel Exoskeleton 

Prusa CORE One is built as an all-steel exoskeleton. The enclosure is an integral part of the printer, providing it with outstanding stability and rigidity. However, maintenance is still simple, and if you need to replace a worn part in a couple of years, it’s a complete no-brainer. You can take everything apart with a screwdriver. As usual with us, we hold parts in stock for years.

All-in-One Package

The CORE One L is equipped with an accelerometer, and the firmware comes with a built-in wizard for setting optimal belt tension. The printer comes pre-calibrated from the factory, but in case you want to ensure you’re getting a 100% performance after carrying out a larger maintenance, you can always recalibrate everything easily from the menu. The printer comes with two nozzles (high-flow and abrasive-resistant) to cover every filament.

Optimized for Print Farms and Industrial Applications

We run a massive print farm with over 600 of our 3D printers producing parts for new 3D printers, so we know what it takes to run such a massive operation. And sometimes, you also need to print massive objects. The CORE One L offers the lowest downtime ratio compared to the MK4S and CORE One.

No Walled Garden or Vendor Locks

In the times of live service games, remote kill switches, and reliance on cloud servers, we’re staying true to our roots: you own your 3D printer, and you can use it for as long as you want, the way you want. It does not require any user account or internet access, so it can keep going forever.

Built on a Strong Foundation

The CORE One L is a larger sibling of the Prusa CORE One, which marked a significant leap forward in the CoreXY market. TechRadar calls it “by far the most advanced and functional printer of this type on the market at present.” Recognized for its excellent build and professional-grade features, it delivers consistently reliable performance with top speed, accuracy, and versatility - earning it the title of “Best Enclosed 3D Printer of 2025” by All3DP. With a Red Dot Award to its name, it also proves that functionality can go hand-in-hand with standout design.
