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 400 °C hotend and 60 °C chamber, you can easily print advanced materials like PC, PA, PPA, PPS, 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.
CGMagazine Review
“I was shocked at how well the machine handles complex geometries with exceptional precision, maintaining tolerances that rival specialized industrial equipment.”
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, PCCF, or even industrial-grade materials like PPS and PPA. 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

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.
Make: Magazine Review
“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.”
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.
Use 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.
HT Hotend supports printing PPS filaments filled with carbon or glass fibers. PPS offers a heat deflection temperature up to 250 °C and great mechanical resistance. It offers extreme chemical resistance and a UL94 V-0 flame-retardant rating. No known solvent can dissolve PPS at temperatures below 200 °C.
Upgradability is what mattersMounting the CORE One L+ with several addons creates a whole new ecosystem
CORE One L+ with the HT Hotend itself allows printing at high temperatures. But the whole set of add-ons makes it easy. HighTemp print sheet provides perfect adhesion for materials like PEI, PEEK, and PEKK, while working perfectly at high-temperature cycles. The USS drybox makes the highly hygroscopic filaments printable without struggle. And the advanced filtration protects your health, as most high-temperature materials emit dangerous fumes.

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.

However, you are completely free to customize your printer to your liking. No parts of the printer are glued together, everything can be taken apart with a set of screwdrivers, and there’s plenty of room for mods, creativity, and customization - so go ahead and make the CORE One L+ your own!
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!
