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.

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.”

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.

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.

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.

Running Costs

The printer purchase is the biggest expense. After that, it's just filament and the occasional spare nozzle or print sheet.

• No vendor locks
• No forced subscriptions
• Free software & firmware upgrades

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.

Prusa USS Drybox

The best solution for printing advanced materials. A sealed storage container built around a simple idea: place
your spool inside, print directly from the box, and leave it there until it’s empty. Perfectly sealed and made exactly
for the CORE One L.

HT Hotend Upgrade

Print materials that require a nozzle temperature up to 400 °C. Unlock engineering polymers like PEKK-CF, PPS-CF,
PPSU or PPA-CF. All easily printable on your CORE One L!

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.

Six engineering choices that set the CORE One L apart:

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 (30 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.
