Prusa CORE One L+ · Technical features from Prusa Research.

NEW
Better prints. Easier everyday use.
The revised platform focuses on shorter preparation, cleaner print starts, surface finish and easier maintenance access.
The new Prusa CORE One L+ brings cleaner print starts, better-looking surfaces, easier operation, and improvements based on feedback from users and the community.

The integrated nozzle wiper cleans filament from the nozzle before printing, helping keep loose strands and small blobs away from the print surface.

New GT1.5 belts make unwanted repeating patterns finer and harder to notice, especially on large, smooth surfaces where even subtle artifacts can stand out.

Latest firmware improvements simplify everyday tasks and reduce the attention the printer needs.
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 Best Large-Format 3D Printer with 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.

Everything is pre-calibrated and factory-tested, ready to go - simply press the Print button. What you pick up from the heatbed can be easily used as the final product you’ll ship to your customers.

The CORE One series represents our fastest printers yet - and they work with every filament, not just special ones. Print faster without losing quality thanks to a high-flow nozzle, CoreXY kinematics, and Input Shaper.

What You Design is What You Get. 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.

With the 60°C chamber, you can easily print advanced materials like ASA, ABS, PC, PA, and more. And the results will be amazing: no cracks, no lifted corners, no warping.

Flexible filaments are notoriously difficult to print. Not with the CORE One L+. Switch it to Flex loading mode, feed the filament, and start producing durable, flexible prints.

Steep overhangs need supports - additional material that is ultimately scrapped. CORE One L+ prints extreme overhangs (up to 75°) without supports, saving material and time.

Metal-Like Strength
Fix broken appliances and produce functional machinery parts with tough, carbon-fiber reinforced polymers like PA11-CF or PCCF. Print RC cars, drones, and mechanical linkages that often exceed the strength of original injection-molded components.

Design it & Make It Locally
With a massive 30-liter build space, you can print large manufacturing jigs, alignment tools, and custom workholding fixtures in one go. Keep your production line running without outsourcing costly CNC parts.

Large Flexible Models
Flexible polyurethane (TPU) is ideal for custom phone cases, camera rigs, vibration dampeners, seals, and protective bumpers. Print flexible, rubber-like items edge-to-edge on the spacious print sheet.

Prototyping & Art
From architectural scale models to movie-grade prop making and cosplay design, the CORE One L+ allows top creators and engineering firms to print highly detailed scale prototypes in single, uninterrupted print cycles.

CT-scan-verified dimensional accuracy across the entire volume means what you design is what you get - no matter how big your project is.

CORE One L+ is designed to run 24/7 without breaking a sweat. Fill the bed edge-to-edge, hit print, and walk away. Wake up to a finished print job.

Cosplay & movie props, masks and large display pieces come out as a single seamless object. No glue lines to sand, no edges to align.

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.

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.

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 CORE One L delivers Prusa’s trademark build quality, offering a large-format machine that still fits on your desk. Its premium price is steep, but the machine’s reliability, plug-and-play ease of use, and security features make it easy to recommend.
View product →Reliable, easy to use, capable of delivering great prints over and over: Prusa's newest system is made for production runs. (...) Although the competition is fierce, Prusa printers possess a unique quality that extends beyond their exceptional print quality and dependability.
View product →I printed large models on the CORE One L that easily stayed stuck in place all the way out to the edges, a feat many large printers struggle with. And with its built-in Wi-Fi, you can send prints to your CORE One L from anywhere on almost any device, using the new EasyPrint feature on Printables.
View product →What we have is one of the best 3D printers on the market, with more potential than any other – and we just have to sit and wait until that full potential is realised. But for now, the Core One and Core One L will sit, working without fuss and reliably, in the workshop as my two favourite 3D printers.

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, we’re including a comprehensive Prusa Academy course on the CORE One L+ at no extra cost with every machine. This is perfect for 3D printing newcomers, in the educational sector, but it also makes onboarding new employees a breeze.

Solid steel exoskeleton
This 3D printer is built like a tank - ready to survive the busiest workshop and the most stressful environments without breaking a sweat. Nothing is glued together, nothing is welded. You can take everything apart with a screwdriver.
Here's a proper tour of the best features!
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.
The all-new, all-aluminum heatbed with dual-loop heating provides beautifully uniform heat distribution, killing warping and cold corners. The printer automatically distinguishes between 110V and 230V grids and intelligently configures the heatbed for consistent performance in any part of the world. Everything is protected by robust multi-layer security systems.

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. It's the perfect companion for your work desk!
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 300×300×330mm (29.7 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)

Published CAD and firmware repositories allow inspection and modification under their respective licences. The printer does not depend on a cloud connection for normal offline printing.

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.

Introducing EasyPrint!
With most projects, you want simple workflow. "I want to print this model from this material and with this quality." EasyPrint is the fastest way to achieve that. Features a real online slicer engine and runs on your phone. Four taps and you're printing. And the best part? If you get CAD files from your colleague, you can easily import them as well.

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 (in each axis) than the CORE One, yet it maintains the same weight, and the print volume is doubled!












The details that matter
Manufacturer figures, with plain-English notes where useful.
23 specifications
Yes, absolutely. The CORE One L+ features a fully physical offline mode. For secure facilities, you can completely remove the Wi-Fi module, and the printer remains fully functional while being air-gapped. Firmware updates, calibration, and slicing via PrusaSlicer can be done entirely via USB drive.
Active chamber heating prevents warping in materials like ABS, ASA, Polycarbonate, and Carbon Fiber composites. By maintaining a uniform 60°C ambient temperature, the printer minimizes internal stress as the layers cool, leading to perfect layer adhesion and excellent dimensional accuracy.
No. Despite its massive dual-loop heated bed and active convection system, the CORE One L+ runs on standard household or workshop power outlets (110V/230V) without requiring dedicated high-amperage lines.
The CORE One L+ is a refinement of the same proven platform. It adds new GT1.5 belts for smoother-looking surfaces, an integrated nozzle wiper for cleaner print starts, and the latest firmware improvements focused on easier everyday use. Everything that defines the CORE One L, including the 300×300×330 mm build volume, 60°C active chamber, and all-aluminum AC heatbed, remains unchanged.
Not at all. The Nextruder architecture makes hotend swaps incredibly straightforward. Swapping to the HT Hotend takes only a few minutes and unlocks printing temperatures up to 400°C for engineering polymers like PEKK-CF, PPS-CF, and PPSU.
Unlike standard beds that rely on radiant heat to slowly warm an enclosure, the AC heatbed of the CORE One L+ actively drives chamber heating. It utilizes two fans mounted on the underside of the massive aluminum heatbed. These fans draw in cooler air and force it across the heated aluminum surface, creating a convection current that rapidly and uniformly pushes the chamber temperature up to its 60°C maximum.
The brass high-flow CHT nozzle is the default workhorse; it maximizes volumetric flow by melting filament more efficiently, which is critical for taking full advantage of the CoreXY speeds on large 300x300x330mm parts. You should swap to the hardened nozzle only when deploying abrasive engineering filaments (like PA-CF or PC-CF), which the 60°C active chamber is specifically designed to handle.
The INDX is more suited for a printer of this caliber. However, we offer a DIY way to re-mount a CORE One+ MMU3 to the CORE One L+ by getting a package from our e-shop and following an online guide.
The CORE One L+ comes pre-assembled and pre-calibrated from the factory. The only installation step consists of attaching a cable to the LCD panel and snapping the LCD panel in place. Plug it in, turn it on, see the introduction screen and you're ready to print. It can't get any easier than this.
