Prusa CORE One L

A versatile 3D printer for any type of project.

Thanks to the print volume of 300 × 300 × 330 mm, an active heated room up to 60 °C and the new AC convection bed is the Prusa CORE One L is perfect for effortless printing of demanding and warping materials. It is the best tool for any type of company, home workshop, shared creator spaces or design studios; All in one package. You can integrate it into the Prusa open ecosystem while remaining completely free from the limitations of a closed ecosystem. Print in top quality with any material, use each slicer and let the printer work completely offline if required. When you purchase a Prusa, you own the machine, not just a license to use it. The exoskeleton frame and smart design choices ensure maximum strength and robustness, which translates directly into excellent print quality. Thanks to the intuitive software, users can start printing their first model with one click within minutes of unpacking. Moreover, access to more than one million free 3D models on Printables.com guarantees a constant supply of interesting projects. So there is always sowithhing to print!

Twice the Core One

The Prusa Core One L is much more than just a larger Prusa Core One+. Prusa has not only enlarged it, but has taken over everything that works well and added features for effortlessly printing in a larger format. Prusa has opted for an effective combination of a solid steel frame and aluminium panels to create a lighter version of our proven exoskeleton design. And the results are convincing: The outside dimensions of the machine are only 10% larger than those of the Prusa Core One, but it still weighs the same and the print volume has doubled! The standard heated bed has been replaced by a new AC convection heated bed with active air circulation for a perfect heat distribution in the build chamber. The Prusa Core One L comes with:

• A removable 1080p camera with night vision
• Twee nozzles bijgesloten
• Fully automatic temperature management in the room
• Eenvoudigere FLEX-filamenttoevoer

This machine can handle anything: from ambitious hobby projects to very demanding production!

Denk groot. Print groot.

Because now everything fits! The print volume of 300×300×330 mm (double the CORE One) is ideal for any project. You can print large functional parts, production facilities, architectural models, tools such as holders and molds and other huge objects, all in one piece. And the best? The new heated bed has the best possible heat distribution thanks to the materials used, so you can easily print from edge to edge.

New AC heated bed with convection heating

No cold corners and quick warming The new massive AC heated bed is made of a thick block of aluminium for the best possible heat distribution. This results in a perfectly uniform heat distribution from edge to edge; No cold spots, no cold corners. You can place the model anywhere in the print area without worrying about raised corners or bending. Two fans at the bottom of the heated bed create a convection effect; they enter cold air and blow it over the massive heated surface to quickly warm up the chamber to 60 °C.

Unpack and print!

5 minutes from unpack to first print Unpack the printer, click the display and connect it. That’s all. No self-tests, calibrations or other operations. The machine controls everything independently, including setting the best printing environment in the print room. Just download sowithhing nice from Printables.com, process it with EasyPrint and see how it is printed.

Start and forget the machine

More printing and less downtime with the larger print volume A larger print volume is not only for large prints, it is for more prints. The Prusa Core One L is the perfect machine for tasks at night or production of large series. The circuit board is 63% larger than that in the CORE One, so you can place considerably more objects on the build plate and make the machine run at night. You can always check progress with a 1080p night vision camera and receive notifications on your phone. This camera can also be removed if required.

Onberispelijke precisie

Wat u ontwerpt, is wat u krijgt Thanks to our internally developed, quality-oriented print profiles, you can be sure that your models look exactly like they were designed, with perfect size accuracy, as proven by CT scans. CORE One L uses the proven Nextruder with 360°-koeling for flawlessly printing overhangs of 75°, saving both time and material.

Beste oppervlaktekwaliteit

Your 3D prints are the end product With the latest updates for PrusaSlicer and the tailored print profiles, your prints look better than ever. Prusa virtually eliminated VFAs (Vertical Fine Artifacts) and ugly vertical stripes on 3D prints. What you pick up from the heatbed, you can easily use as a final product for your customers.

Maximum speed without catch

Quickly with any filament, not only with specialised filaments Do not limit your projects to a small selection of specialised high-speed filaments. Use PLA, PETG or many advanced materials. The CORE One series represents our fastest printers so far: robust CoreXY kinematics, a high-flow nozzle, Input Shaper, factory-fitted print profiles for over 200 filaments, it’s all there. The prints are always sturdy and durable.

Effortless printing with advanced materials

Designed to print durable models without warping! The room is as compact as possible and thanks to the new active heat circulation of a new, powerful heated bed with two fans, it warms up to 60 °C in record time. You can easily print advanced materials like ASA, ABS, PC, PA (nylon) and much more. And the results will be amazing: no cracks, no raised corners, no curved prints.

A real FLEX!

New option for placing flexible filaments The lateral filament sensor can be switched to flexible filament charging mode with 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 loop.

Robuust stalen exoskelet

A design that works and looks good The Prusa Core One is built as a full steel exoskeleton. The enclosure is an integral part of the printer and offers excellent stability and solidity. However, maintenance is still easy and if you need to replace a worn-out part in a few years, that’s a piece of cake. You can disassemble anything with a screwdriver. As usual with Prusa, parts are in stock for years.

All-in-one package

Take direct advantage of the box of best performance The Prusa Core One L is equipped with an accelerator and the firmware is equipped with a built-in wizard to adjust the optimal belt tension. The printer comes calibrated off-factory, but if you want to be sure of 100% performance after a larger maintenance, you can easily recalibrate everything from the menu. The printer comes with two nozzles (high flow and a hardened version) to print each filament.

Optimized for print farms and industrial applications

Increase your production with the Prusa Core One L! Prusa has a huge print farm with over 600 of own 3D printers that produce components for Prusa 3D printers. The CORE One L offers the lowest downtime compared to the MK4S and CORE One.

Geen gesloten ecosysteeem of leverancierssloten

You own your printer, not just a license to use it During the time of live service games, killswitches remotely and dependence on cloud servers Prusa remains loyal to its roots: you are the owner of your 3D printer and you can use it as long as you like, as you like. It does not require a user account or Internet access, so it can continue to work forever.

Built on a strong base

The Prusa Core One L is a larger brother of the Prusa Core One, which meant a big leap forward in the CoreXY market. TechRadar calls it “by far the most advanced and functional printer of this type currently on the market.” It is known for its excellent construction quality and professional features and consistently delivers reliable performance with top speed, accuracy and versatility; which gave him the title “Best closed 3D printer of 2025” of All3DP. With a Red Dot Award he also proves that functionality can go hand in hand with a striking design.
