Whether you are just starting with 3D printing or are an experienced professional, the Prusa CORE One will be your reliable and versatile printer for every project. Its enclosed print chamber and CoreXY kinematics ensure high-speed and high-quality printing, with a generous build volume of 250 × 220 × 270 mm. The CORE One also features a smart design – its all-metal exoskeleton provides maximum durability and robustness. With intuitive software and one-click printing, you can start your first 3D model within minutes. With nearly a million models available on Printables.com, you’ll never run out of great prints!
The Prusa CORE One continues the long-standing tradition of hardworking 3D printers. Designed for maximum durability and built with premium materials, the CORE One is exceptionally reliable and requires minimal maintenance.
Enclosed print chamber with active temperature control
The CORE One’s print chamber can reach up to 55 °C, ensuring perfect print quality across materials – from PLA and PETG (even with doors closed) to more demanding filaments like ASA, PC, or Nylon.
Plug and print!
From unboxing to first print in 10 minutes – just unpack the printer, perform a one-time calibration, and start printing. The CORE One is equipped with advanced sensors for trouble-free printing, automatically calibrates the first layer, and will pause and alert you if filament runs out.
Flawlessly precise
Top print quality with Nextruder
You can rely on your models turning out exactly as designed – the print profiles have been internally fine-tuned for maximum quality and dimensional accuracy. The CORE One fully leverages the enhanced Nextruder with 360° cooling, allowing you to print up to 75° overhangs without supports, saving both time and material.
Maximum speed without compromise
CORE One prints any filament fast, not just the special ones
Don’t limit your projects to a narrow selection of “high-speed” filaments – use any PLA, PETG, or one of the advanced filaments. Robust CoreXY kinematics, custom-tuned profiles for 200+ filaments, a high-flow nozzle, and Input Shaper make the CORE One our fastest printer yet, without ever prioritizing speed over perfect print quality.
Compact footprint, big prints
Perfect choice for home, work, or a print farm
The Prusa CORE One occupies 50 % less space than the MK4S in an Enclosure, yet offers an impressive 30 % larger build volume. Efficient space usage is something we appreciate too! We operate a massive print farm with over 600 3D printers, and thanks to the compact size and refined design of the CORE One, we can fit more printers in the same space, increasing overall production.
Best choice for advanced materials
Print functional and durable models without warping!
The CORE One chamber is compact and features clever recesses on each side to reduce volume. This allows it to heat up quickly to up to 55 °C, ensuring easy printing of materials such as ASA, ABS, PC, PA (Nylons), and other advanced filaments without warping. The automatic ventilation system and active temperature control also ensure seamless PLA printing – even with the doors fully closed!
Robust steel exoskeleton
Beautiful and functional design
The Prusa CORE One is built on a full-metal exoskeleton. The enclosed box is an integral part of the printer, giving it incredible strength and stability. Maintenance remains simple – if you ever need to replace a part, it’s easy with just a screwdriver. And as always, replacement parts will remain in stock for many years.

Prusament
We weren’t satisfied with the quality of filaments available on the market, so we started producing our own! Prusament delivers exceptional manufacturing precision, perfect color consistency, and a wide range of materials from PLA to PCCF. Every Prusament material comes with a PrusaSlicer profile tested directly by us.
Network Connectivity
The Prusa CORE One is equipped with a LAN port and a removable Wi-Fi module (Wi-Fi can be easily set up via NFC). The printer seamlessly connects to Prusa Connect and the Prusa App, keeping you always in control. The CORE One also fully operates offline, and the firmware can even be updated directly from a USB drive.
Create Colorful 3D Models!
Ready for MMU3
The CORE One is compatible with MMU3, an accessory for the fastest single-nozzle printing with up to five filaments simultaneously. With MMU3, you can create impressive multi-color models without wasting filament or constantly tidying up around the printer. MMU3 switches filaments using an innovative retraction technique and a compact cleaning tower, saving filament and collecting print waste into a compact, cohesive block.
Make It Your Own!
Designed for Modders
No printer parts are glued together – everything can be disassembled with just a screwdriver set. The CORE One gives you plenty of room for modifications, creative adjustments, and personalization, so you can customize it exactly the way you want. Print magnetic holders, organizers, or fun accessories and let your printer stand out!
Our software and firmware are open-source – the source code is available on GitHub.com. This allows you to modify the code yourself and design your own enhancements and improvements. We often collaborate on new features with members of our community, and you can join in! If programming isn’t your thing, you can still dive into modifying printed parts of the printer. There are countless projects for upgrades waiting to be explored!
Enhance Your CORE One with Accessories!
The CORE One can be upgraded with practical accessories. We offer an optional USB-C camera, and with an additional accelerometer for modified printers, you can fine-tune profiles for Input Shaper. For enthusiasts, we provide a GPIO hackerboard, allowing you to control external devices using G-code commands.
We’re also preparing two different types of filtration, a drybox, and other accessories – plenty to look forward to!
Chamber Camera
You can install an optional high-resolution camera inside the CORE One chamber to monitor prints remotely. The camera connects directly to the mainboard via a USB-C cable and requires an active Wi-Fi connection to operate.
The camera is expected to be available around the same time as the Prusa CORE One. If you order the printer before the camera becomes available, we will offer you the option to modify your order and add the camera.
GPIO Hackerboard
The GPIO module is an optional accessory for advanced 3D printers (requires basic programming and soldering skills). It allows you to expand your printer with new functionalities, enabling you to control and receive inputs from external devices via GPIO pins and G-code commands.
For example, you can remotely control LED lighting or trigger a DSLR camera.
Advanced Filtration System
Studies show that most commonly used 3D printing materials are generally safe. However, we wanted absolute certainty. The optional advanced filtration system is ideal for printing materials like ASA, which release higher amounts of fumes and ultrafine particles during printing. The fewer particles and odors in the air, the better.
The filtration system is expected to be available around the same time as the Prusa CORE One. If you order the printer before the filtration system is available, we will offer you the option to modify your order and add it.
Future-Ready
Exceptional Backward Compatibility
When you purchase the CORE One, you’re not investing in a machine you’ll need to replace in a year or two, but in a platform that will continue to evolve. Prusa printers are well-known for their extraordinary reliability, durability, and long lifespan. After launch, we provide top-notch support with regular firmware updates and even hardware upgrades that enhance your printer’s capabilities years after release. When a new printer model is released, we offer a conversion kit.
New technology releases are often exciting but can also bring inconvenient changes. You might need a new charger or a different phone case because the camera moved. For CORE One, this is not the case! If you already own an MK4/S, you can reuse many accessories, such as print beds, nozzles, and hotends. The CORE One uses many proven parts from the MK4S, which is why we also offer a practical conversion kit.
