設計して、その場で製造
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.

大型フレキシブルモデル
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.

プロトタイピング&アート
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.

CT-scan-verified dimensional accuracy across the entire volume means what you design is what you get - no matter how big your project is.

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.

Cosplay & movie props, masks and large display pieces come out as a single seamless object. No glue lines to sand, no edges to align.
“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.”

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.
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.

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.






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.

Reliable, easy to use, capable of delivering great prints over and over: Prusa's newest system is made for production runs. (...) Although the competition is fierce, Prusa printers possess a unique quality that extends beyond their exceptional print quality and dependability.
VoxelMattersI 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. And with its built-in Wi-Fi, you can send prints to your CORE One L from anywhere on almost any device, using the new EasyPrint feature on Printables.

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.
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.
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.
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.

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.
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.
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!
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!

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.

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.

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.

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.
With most projects, you want simple workflow. "I want to print this model from this material and with this quality." EasyPrint is the fastest way to achieve that. Features a real online slicer engine and runs on your phone. Four taps and you're printing.
And the best part? If you get CAD files from your colleague, you can easily import them as well.

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!
