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.

 

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.

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!

Outstanding Print Quality, Incredibly Reliable, and 100% Secure!

See it in action in the video below - from automated calibration to high-speed printing of demanding materials. Learn how its all-aluminum heatbed with convection-style heating redefines the way you will be printing large objects from now on!

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!

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.

Right to Repair

Nothing is glued. Everything comes apart with a screwdriver. We keep spare parts in stock for years after release. A worn nozzle (after hundreds of print hours) is a $20 swap, not a reason to worry.

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.

Make it your own!

The printer comes assembled and pre-calibrated from the factory, so you don’t have to do anything to get the best performance out of the box. 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!
