The Prusa CORE One+ (Assembled) is an enclosed CoreXY 3D printer built for fast, accurate printing across everyday and advanced materials. It combines a large 250 × 220 × 270 mm print area with a rigid all-steel exoskeleton, active chamber temperature control up to 55 °C, and a workflow designed to get from unpacking to first print in minutes.

Whether the goal is reliable PLA production, stronger functional parts in ASA or Nylon, or a compact machine for a workshop or print farm, the CORE One+ is designed as a durable, low-maintenance workhorse. Intuitive software, one-click printing, automatic calibration, and integrated remote tools reduce setup time while preserving print quality.

What’s new in the Prusa CORE One+

The CORE One+ combines hardware quality-of-life improvements adopted from the CORE One L with firmware updates developed across the full lifespan of the CORE One platform. The result is smoother operation, improved print quality, and a more autonomous day-to-day experience.

Key improvements in the CORE One+

• Automatic Top Vent Operation: The extruder automatically opens the vent for low-temperature materials such as PLA and PETG, and closes it for high-temperature materials to maintain the correct thermal environment.
• Easy Flex Loading: A redesigned filament insertion point makes flexible filament loading quicker and simpler.
• New Bayonet-Style Spoolholder: The updated holder supports various spool sizes and is ready for a direct-feed drybox.
• Firmware & Performance Updates: The printer includes software refinements from the CORE One platform’s full development cycle for improved print consistency and smoother operation out of the box.

Ready for INDX multi-material toolchanging

The CORE One+ is built to support the INDX upgrade, a toolchanging system developed in collaboration with Bondtech. INDX allows up to 8 different colours or materials in a single print and switches between them automatically in seconds with near-zero waste.

At the centre of the system is one active Smart Head that picks up lightweight passive tools and heats them using contactless magnetic induction. Combined with the self-adjusting Dynamic Extruder that automatically optimizes gear tension for each filament, the INDX system is designed to make complex multi-material printing more reliable and easier to manage.

The Founders Edition is currently sold out and scheduled to arrive in Q1 2026.

HT Hotend Upgrade for 400 °C printing

The optional High Temp Hotend Upgrade expands the CORE One+ into higher-temperature applications. This quick-swap upgrade installs in less than a minute and raises printing capability to 400 °C.

What the HT Hotend Upgrade adds

• Access to high-performance polymers: Print industrial-grade materials such as PEKK-CF, PPS-CF, PPSU, PPA, and PPA-CF.
• Improved part strength with existing materials: Higher-temperature processing can deliver stronger layer adhesion and produce up to 30% sturdier parts from filaments such as ASA, PA11CF, PCCF, and even PETG.
• Support for certified applications: The upgrade enables production of parts intended to meet rigorous certifications such as AS9100 or ISO 10993 for critical long-term applications.
• Broader professional use: The expanded material range suits R&D, automotive, aerospace, and medical workflows.

Fast setup and automated printing workflow

10 minutes from unpacking to first print

Setup is designed to be straightforward: unpack the printer, complete a one-time calibration, and begin printing. The CORE One+ uses advanced sensors to automate routine steps and reduce manual intervention during prints.

Automatic first-layer calibration helps establish a consistent start, while the printer can pause a job and send a notification if filament runs out. The result is a more hands-off workflow for routine printing and longer jobs alike.

Print quality and dimensional precision

Nextruder performance with 360° cooling

The CORE One+ uses the upgraded Nextruder together with in-house developed print profiles focused on dimensional accuracy and consistent results. Models are designed to print as intended, with clean detail and dependable geometry.

The 360° cooling system enables reliable printing of 75° overhangs, which can reduce support use and save both material and post-processing time.

High speed without limiting material choice

Fast printing with standard and advanced filaments

The CORE One+ is Prusa’s fastest printer yet, using robust CoreXY kinematics, a high-flow nozzle, Input Shaper, and factory-tuned profiles for 200+ filaments. That speed is not restricted to niche high-speed materials.

Users can print with standard PLA and PETG as well as advanced materials while maintaining print quality. This makes the printer suitable for prototyping, production runs, and everyday workshop use without narrowing filament options.

Compact footprint with a large enclosed build space

Designed for home use, workplaces, and print farms

The CORE One+ takes up 50% less space than the MK4S inside an enclosure while delivering a 30% increase in print volume. That combination helps users fit more printer capacity into limited space.

Prusa highlights the same efficiency in its own print farm of over 600 machines, where footprint and layout directly affect throughput and production density.

Enclosed chamber for advanced materials

Up to 55 °C chamber temperature with active control

The chamber is designed to be as compact as possible, with recessed sides that reduce internal volume and help the chamber heat quickly. Temperatures up to 55 °C improve conditions for printing demanding materials while reducing the risk of warping.

ASA, ABS, PC, PA (Nylons), and other engineering materials benefit from the enclosed, actively controlled environment. The automatic ventilation system also allows reliable PLA printing even when the door stays closed.

All-steel exoskeleton for rigidity and serviceability

Stable structure with simple maintenance access

The CORE One+ uses an all-steel exoskeleton where the enclosure is an integral part of the printer structure. This design increases stability and rigidity, supporting print quality at higher speeds.

Despite the rigid construction, maintenance remains straightforward. No parts are permanently glued together, and the printer can be disassembled with a screwdriver, making long-term servicing and worn-part replacement simpler.

Recognition, reviews, and industrial design awards

The Prusa CORE One was described by TechRadar as by far the most advanced and functional printer of this type on the market at present. It was also named Best Enclosed 3D Printer of 2025 by All3DP for its build quality, professional-grade features, speed, accuracy, reliability, and versatility.

The platform has also received a Red Dot Award, highlighting the balance between functional engineering and industrial design.
