Prusa CORE One+ kit

What's New in the CORE One+ kit

The Prusa CORE One+ is the next evolution of our proven workhorse. It integrates key hardware quality-of-life improvements adopted from the CORE One L, combined with all the firmware updates developed over the entire lifespan of the CORE One.

This combination delivers the best print quality, smoother operation, and a more autonomous, hassle-free user experience.

Key features:

• Automatic Top Vent Operation: The extruder now automatically opens the vent for low-temp materials (PLA/PETG) and closes it for high-temperature materials, ensuring the optimal thermal environment and creating a true "set-and-forget" experience.
• Easy Flex Loading: A redesigned filament insertion point makes the process of feeding flexible filaments quick and simple.
• New Bayonet-Style Spoolholder: Allows you to use various spool sizes. Ready for a direct-feed drybox.
• Firmware & Performance: Includes all software updates from the entire lifespan of the CORE One, resulting in even better print quality and smoother operation right out of the box.

Upgrade Your CORE One!

Current CORE One owners can easily upgrade to the new CORE One+! You can either download the free print-it-yourself files from Printables or purchase the official upgrade kit.

Ready for the INDX Upgrade

The CORE One+ is built to support the INDX upgrade, 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.

At the heart of the system is a single active Smart Head that picks up lightweight, passive tools and heats them using contactless magnetic induction. This technology enables ultra-fast heating and cooling cycles. Combined with the self-adjusting Dynamic Extruder that automatically optimizes gear tension for every filament, the INDX makes complex multi-material printing reliable and easy. The Founders Edition is currently sold out and scheduled to arrive in Q1 2026. Learn more and sign up for updates.

HT Hotend Upgrade: Print at 400 °C

Take your printer to the next level with our new High Temp Hotend Upgrade, available for the entire CORE One family (CORE One, CORE One+, and CORE One L).

This simple, quick-swap upgrade installs in less than a minute and unlocks the ability to print at 400 °C, allowing you to:

• Unlock New High-Performance Polymers: Print with industrial-grade materials like PEKK-CF, PPS-CF, PPSU, PPA, and PPA-CF, known for their exceptional temperature and chemical resistance.
• Boost Existing Part Strength: Achieve stronger layer adhesion and produce up to 30% sturdier parts from existing filaments such as ASA, PA11CF, PCCF, or even PETG.
• Meet Industry Standards: This upgrade allows you to print parts that meet rigorous certifications (like AS9100 or ISO 10993) for critical, long-term applications.
• Expand Your Possibilities: With the HT Hotend Upgrade, your printer becomes an even more versatile machine for various industries, including R&D, automotive, aerospace, and medicine.

Plug and Print!

10 minutes from unpacking to first print

Unpack the printer, perform a one-time calibration, and you’re ready to go. Equipped with advanced sensors for hassle-free printing, the CORE One+ is a true “start and forget” machine. Simply start your print and let the printer handle the rest, from fully automatic first-layer calibration to pausing the print and sending a notification if the filament runs out.

Flawless Precision

Outstanding print quality thanks to the Nextruder

You can be sure that with our internally developed, quality-focused print profiles, your models will turn out exactly the way they were designed, with perfect dimensional accuracy. CORE One+ takes advantage of the upgraded Nextruder with 360° cooling that enables flawless printing of 75° overhangs, saving both time and material.Maximum Speed without a catch

The CORE One+ is fast with every filament, not just specialized ones

Don’t limit your projects with a small selection of specialized “high-speed” filaments. Use any PLA, PETG or any of the advanced materials. While the CORE One+ is our fastest printer yet thanks to its robust CoreXY kinematics, high-flow nozzle, Input Shaper and factory-tuned print profiles for 200+ filaments, it never sacrifices quality for quicker print times.

Compact Footprint, Large Volume

The perfect fit for any home, workplace or print farm

The Prusa CORE One+ takes up 50% less space than the MK4S inside an enclosure, yet it delivers an impressive 30% increase in print volume. Space efficiency matters - even for us! With a massive 3D print farm of over 600 machines, the CORE One+'s compact footprint and optimized design let us fit even more printers into the same space and boost our production.

The Best Solution for Advanced Materials

Print durable functional models easily and without warping!

The chamber is as compact as possible, with a cleverly designed recess on each side to minimize its volume. This allows the chamber to quickly reach higher temperatures (up to 55°C), enabling you to print ASA, ABS, PC, PA (Nylons), and other advanced materials smoothly, without warping. The automatic ventilation system and active temperature control enable flawless printing of PLA - even with the door completely closed!

Robust Steel Exoskeleton

A design that works and looks the Part

Prusa CORE One+ is built as an all-steel exoskeleton. The enclosure is an integral part of the printer, providing it with outstanding stability and rigidity. However, maintenance is still simple, and if you need to replace a worn part in a couple of years, it’s a complete no-brainer. You can take everything apart with a screwdriver. As usual with us, we hold parts in stock for years.
