Prusa CORE One L - 300 build volume

This is the versatile 3D printer for every kind of project.

Thanks to the print volume of 300×300×330mm, an actively heated chamber up to 60°C, and the new AC convection heatbed, it is perfect for effortless, warp-free printing of demanding materials. It’s the best tool for every kind of business, home workshop, shared makerspaces, or design studios - all in one package. You can integrate it into our open ecosystem while remaining completely free from the limitations of a walled garden.

Print in top quality with any material, use any slicer, and run the printer completely offline if you choose.

When you get a Prusa, you own the machine, not just a license to use it.

CORE One - Doubled!

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.

Because now everything fits!

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

No cold corners, fast heat up

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.

Maximum Speed without a catch

The CORE One L is fast with every filament, not just specialized ones

Don’t limit your projects with a small selection of specialized “high-speed” filaments. Use any PLA, PETG or any of the advanced materials. While the CORE One is our fastest printer yet thanks to its robust Core XY kinematics, high-flow nozzle, Input Shaper and factory-tuned print profiles for 200+ filaments, it never sacrifices quality for quicker print times.

The Best Solution for Advanced Materials

Print durable functional models easily and without warping!

The chamber is as compact as possible, with a cleverly designed recess on each side to minimize its volume. This allows the chamber to quickly reach higher temperatures (up to 55°C), enabling you to print ASA, ABS, PC, PA (Nylons), and other advanced materials smoothly, without warping. The automatic ventilation system and active temperature control enable flawless printing of PLA - even with the door completely closed!

Robust Steel Exoskeleton

A design that works and looks the Part

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.
