Prusa, a Czech Startup focused on desktop 3D printers and materials, has unveiled its latest innovation, the Prusa CORE One, a fully enclosed CoreXY 3D printer with active chamber temperature control. Set to begin shipping in January 2025, this versatile machine combines speed, quality, and advanced features in a compact design that offers a 250×220×270 mm build volume.
The CORE One, which will retail at an introductory price of USD 1,199 (VAT excl.) and EUR 1,349 (VAT incl.), represents a new product line for Prusa rather than a successor to the MK4S. The company has confirmed it will continue manufacturing and supporting the MK4S with firmware updates and additional accessories.
Prusa CORE One – CoreXY 3D printer
The printer features an innovative exoskeleton structure inspired by nature, where the outer frame serves as both structural support and design elements. This approach not only improves robustness but also enhances manufacturing efficiency.
A standout feature is the printer’s ability to maintain optimal chamber temperatures up to 55°C through active temperature control. Unlike traditional enclosed printers, the CORE One can efficiently print PLA and PETG with closed doors, thanks to dual fans at the back that ensure temperature regulation. Users simply need to open a small vent on top for printing these materials.
“About 90 percent of all prints are made with PLA or PETG,” notes Prusa, highlighting the importance of this feature for everyday users. The printer’s transparent panels are constructed from high-end polymer, making them virtually indestructible and ideal for transport and workplace safety.
Enhanced Performance and Print Quality
The CORE One incorporates several key features:
- Nextruder system with 360° cooling for exceptional print quality
- Loadcell sensor for precise first layer calibration
- 15-20% faster printing speeds compared to the MK4S
- Compatibility with a wide range of materials including PLA, PETG, ASA, ABS, PC, and Nylon
- 30% smaller footprint compared to the MK4S while offering 30% more print volume
Modular Design and Future-Proof Features
- The printer emphasizes repairability and customization:
- Easy disassembly with regular screws
- CoreXY functional assembly replaceable in under 20 minutes
- Magnetic attachment points for custom holders and organizers
- Open-source software and firmware
- Full compatibility with GPIO hackerboard and accelerometer
- Support for MMU3 multi-material upgrade
New Buddy3D Camera and ‘Prusaverse’
Prusa is also launching a new USB-C camera under its Buddy3D brand, designed to work seamlessly with the CORE One and future models. The camera integrates with Prusa Connect and the Prusa App for remote monitoring, though Wi-Fi connectivity remains optional for security-conscious users.
The printer fully integrates with the “Prusaverse” ecosystem, including:
- Printables.com for 3D models
- PrusaSlicer with optimized profiles for 200+ materials
- Prusa Connect for remote management
- Native iOS/Android Prusa App
- Prusa Academy courses and tutorials
- Upgrade Path and Assembly Options
For existing users, Prusa will offer a conversion kit in March 2025, priced at USD 449 (VAT excl.) or EUR 489 (VAT incl.), allowing MK4S owners to upgrade to the CORE One. The printer will also be available as an assembly kit in April 2025, priced at USD 949 (VAT excl.) or EUR 1,049 (VAT incl.).
Additional accessories in development include two types of filtration systems (HEPA and advanced) and a drybox, with details to be announced in future newsletters.
The CORE One maintains backward compatibility with existing Prusa components, including print sheets, hotends, and nozzles from the MK3/MK4 series, making it an economical choice for print farms and existing Prusa users.
With its focus on quality, speed, and versatility, the CORE One represents Prusa’s vision for the future of 3D printing, offering a robust platform that can be expanded and upgraded for years to come.
