When you buy a Prusa, the machine belongs to you—not just a license to use it.
The exoskeleton frame and smart design ensure maximum strength and rigidity, directly resulting in excellent print quality. Thanks to the intuitive software and one-click printing, you can start your first print just minutes after unboxing. And with access to over one million free 3D models on Printables.com, you’ll never run out of exciting projects. There's always something to print!
CORE One – Doubled!
Large print volume, active heat circulation, and more!
The CORE One L is much more than just a bigger CORE One. We didn’t simply scale it up; we kept everything that worked well and added features for effortless large-format printing.
For the enclosure, we chose an effective combination of a solid steel frame and aluminum panels to create a lighter version of our proven exoskeleton design. And the result speaks for itself: the external dimensions of the device are only 10% larger than the CORE One, yet with double the print volume and the same weight!
The standard heatbed has been replaced with our new AC convection heatbed featuring active air circulation for flawless heat distribution inside the chamber. The printer also features a detachable 1080p night-vision camera, 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 demanding production!
Think big. Print big.
Because now everything fits!
The 300×300×330 mm build volume (double the CORE One volume) is the sweet spot for any type of project. You can print large functional parts, production jigs, architectural models, full-size cosplay helmets, and other big objects—all in one piece. And the best part? The new heatbed provides the best possible thermal distribution thanks to the materials used, enabling effortless edge-to-edge printing.
New AC Heatbed with Convection Heating
No cold corners, fast heating
The new massive AC heatbed is made from a thick aluminum block to ensure the best possible heat distribution. The result is perfectly even heating from edge to edge—no cold spots, no cold corners. You can place your model anywhere on the bed without worrying about lifting or warping. Two fans underneath the heatbed create a convection effect—pulling in cold air and blowing it across the heated surface to bring the chamber quickly to 60°C.
Unbox and Print!
5 minutes from unboxing to first print
Unbox the printer, click the display into place, and plug it in. That’s it. No self-tests, calibrations, or tinkering. The device handles everything on its own, including preparing the ideal printing environment inside the chamber. Simply download something cool from Printables.com, slice it with EasyPrint, and watch it print immediately.
Start-and-Forget Machine
More print jobs and less downtime thanks to larger build volume
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 batch production. The printbed is 63% larger than that of the CORE One, allowing significantly more objects to be placed and printed overnight. With the 1080p night-vision camera, you can check progress anytime and receive notifications on your phone.
Flawless Precision
What you design is what you get
You can be confident that your models will turn out exactly as designed using our internally developed, quality-focused printing profiles—with perfect dimensional accuracy, as confirmed by CT scans. The CORE One L uses the proven Nextruder with 360° cooling for flawless 75° overhang printing, saving both time and material.
Best Surface Quality
Your 3D prints are the final product
With the latest PrusaSlicer updates and our internally tuned print profiles, your prints will look better than ever. We’ve nearly eliminated VFAs (Vertical Fine Artifacts) and ugly vertical banding on 3D prints. What you take off the heatbed can be used directly as a final product that you can deliver to customers.
Maximum Speed Without Compromises
Fast with any filament—not just special high-speed ones
Don’t limit your projects to a small selection of “high-speed” filaments. Use any PLA, PETG, or many advanced materials. The CORE One series is our fastest printer yet: robust CoreXY kinematics, high-flow nozzle, Input Shaper, factory-tuned profiles for more than 200 filaments—all of this is included. But we never sacrifice print quality for speed records. Prints are always solid, durable, and won’t crumble in your hands.
Hassle-free printing with modern materials
Designed to print durable models without warping!
The chamber is as compact as possible, and thanks to the new active heat circulation via the new high-performance heatbed with two fans, it heats up to 60°C in record time. This allows you to easily print advanced materials like ASA, ABS, PC, PA (Nylon), and more. And the results will be stunning: no cracks, no lifted edges…
