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.
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.
What Can You Make with a 30-Liter Build Volume?
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.
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.
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.
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.
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.
100% privacy: offline mode without compromise
CORE One L Passes Your Security Audit – Easily
The CORE One L never requires a network connection. Configure the printer, slice models, and install firmware updates offline without sacrificing any features or performance. For environments requiring strict security, the Wi-Fi module can be physically removed.
Government agencies, high-clearance manufacturing, and companies handling sensitive data can operate with the absolute guarantee that the printer will never share a single byte of data with any cloud infrastructure.
Designed for facilities with strict security protocols, the Critical Infrastructure Bundle guarantees offline safety: zero Wi-Fi circuitry, no built-in cameras, and a certified, encrypted USB drive.
No self-tests, calibrations, or tinkering
Unpack, Plug in, Start Printing
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
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 CORE One L's best features – the engineering choices that set it apart.
All-Aluminum AC Heatbed
Under 2°C variance across 99% of the surfaceThe 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
Convection heating to a stable 60 °CTwo 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
Travel speeds reaching 500 mm/sThe 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
Built like a tank, lighter than the CORE One+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!
Published CAD and firmware on GitHub since 2012
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.
Compact Footprint, Massive Print Volume
Twice the print volume, barely more desk spaceCompared 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 (30 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)
Automatic Chamber Vent Control
The right thermal environment, automaticallyWhen 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
Monitor prints and create timelapsesA 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
HEPA, active carbon, or your own HVACFor 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.

Upgradability
Whenever it's even remotely possible, we offer our customers a clear and transparent upgrade path. When an improved model comes out, you can usually upgrade the printer you have at home.
Accessories to Consider
CORE One L works perfectly out of the box. Still, you may want to consider these accessories to level up your 3D printing game.
Advanced Filtration System
The optional Advanced Filtration System is useful when you print materials such as ASA and other materials that produce an increased number of ultra-fine particles and fumes during printing.
