NEW
The whole Prusa lineup just got upgraded
Better prints. Easier everyday use.
We focused on the everyday experience, with better-looking prints, faster preparation, easier maintenance, and fewer things you need to take care of yourself.
What's new in the Prusa CORE One L+
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.
Cleaner print starts
The integrated nozzle wiper cleans filament from the nozzle before printing, helping keep loose strands and small blobs away from the print surface.
Smoother-looking surfaces
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.
Easier to use
Latest firmware improvements simplify everyday tasks and reduce the attention the printer needs.
Flawless Results with the Market's Best Heatbed.
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.
Think Big. Print Bigger.
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.
Your 3D Prints are The Final Product
Best Surface Quality
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.
Top Speed without a Catch
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.
Flawless Precision & Repeatability
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.
Durable Models Without Warping
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.
A Proper FLEX!
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.
Extreme Overhangs
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.
What Can You Make with a 30-Liter Build Volume?
Metal-Like Strength
Replacement and Engineering Parts
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
Complex Jigs, Tools and Fixtures
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
Vibration and Impact Absorbers
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
Prototyping, Props and Cosplay Parts
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.
A Large 3D Printer Changes Everything
Large Prototypes that Match the Drawing
CT-scan-verified dimensional accuracy across the entire volume means what you design is what you get - no matter how big your project is.
A Production Run While You Sleep
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.
A Full Helmet in One Print
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
Print Huge Objects - From Edge to Edge
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
Perfect Environment for Any Material
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
GET CORE ONE L+ NOW, UPGRADE TO INDX LATER
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.

Solid steel exoskeleton
Made to Last
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.
Let's Look Under the Hood!
Here's a proper tour of the best features!
Six engineering choices that set the CORE One L+ apart:
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.
All-Aluminum AC Heatbed with only <2°C Variance Across 99% of the Surface
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.
Active Chamber with Smart Temperature Management
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.
Fully Enclosed CoreXY Architecture
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.
Robust Steel Exoskeleton
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!
Compact Footprint, Massive Print Volume
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)
Open Source Approach
CAD files are published. Firmware source code is on GitHub. You can inspect, modify, or compile your own version. No locked bootloaders, no cloud dependency. We've been shipping open-source printers since 2012.
Automatic Chamber Vent Control
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.
1080p Camera with Night Vision
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.
Ready for HVAC
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.

CORE One - Doubled!
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!

Frequently Asked Questions
Can the CORE One L+ really run 100% offline?
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.
What is the advantage of active chamber heating up to 60°C?
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.
Does it require special electrical installations?
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.
What are the differences between the CORE One L and the CORE One L+?
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.
Is the HT Hotend upgrade difficult to install?
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.
How does the new AC convection heatbed heat the chamber faster than standard passive beds?
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 printer includes both a brass high-flow CHT nozzle and a hardened nozzle. How should I deploy these in a production environment?
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.
Is the CORE One L natively compatible with the MMU3?
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.
How much time do I actually spend setting up the printer? Is this a good starter printer?
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.
