Prusa CORE One+ (Gen 2) Assembly kit

What’s new with CORE One+ (Gen 2)?

The second generation keeps the same CORE One platform and adds several practical improvements: less waiting before a print starts, cleaner starts, smoother-looking surfaces, and easier access for maintenance. Firmware updates also continue to make everyday operation simpler.

Faster print starts

The redesigned heatbed mounting removes the separate “Absorbing heat” wait for materials using bed temperatures up to 85 °C. Higher-temperature materials benefit from a shorter wait as well.

Smoother‑looking surfaces

New GT1.5 belts make unwanted repeating patterns finer and harder to notice, especially on large, smooth surfaces where even subtle artifacts can stand out.

Cleaner print starts

The integrated nozzle wiper cleans filament from the nozzle before printing, helping keep loose strands and small blobs away from the print surface.

Your First Print in Three Steps

You'll have your first 3D print in your hands in no time. No tinkering required.

1. Unbox and set up in 10 Minutes

Hassle-free setup

Attach the display, plug it in and run the one-time automatic calibration. The printer handles leveling and sensor checks on its own. No manual adjustment, no guesswork.

2. Pick something awesome to print

Print-ready files

Browse over a million free models on Printables.com - from phone stands and tools to art and mechanical parts. Use EasyPrint on your phone to prepare the model for printing with few quick taps.

3. Hit Print and Walk Away

...or stay and watch!

Transfer your model into the printer via Wi-Fi, USB, or the Prusa app. Press Start. The printer auto-calibrates, heats up, and handles the rest. It'll notify you when it's done.

What can be 3D-printed?

Der CORE One+ wird Sie mit seiner unendlichen Vielseitigkeit überraschen. Fügen Sie Ihrer Bestellung unbedingt ein paar Prusament-Spulen hinzu, damit Sie verschiedene Dinge ausprobieren können!

Hobbies, Household & Fun

Creative Projects

PLA is the ultimate "first print" filament. It is easy to use, comes in every color, and is perfect for detailed toys, board game pieces, desk gadgets or kitchen accessories.

Repairs & Workshop Projects

Replacement Parts

Fix broken appliances with PETG or PCCF. Print RC cars, drones, and mechanical parts.These materials are tough, heat-resistant, and create parts that often outlast the original.

Gadgets & Protection

Impact Absorbers

TPU is a rubber-like material ideal for custom phone cases, GoPro mounts, seals, and protective bumpers. The possibilities are nearly endless!

Engineering & Safety

The WOW!-Faktor

You can get all sorts of materials for your CORE One+, including the brightest glow-in-the-dark filament on the market or beautiful Woodfil filaments.

The fastest way from idea to 3D print

Introducing EasyPrint!

People often ask: how difficult it is to begin with 3D printing? With EasyPrint, anyone can start in a few minutes. Prusa EasyPrint app runs in any browser - on your phone, tablet, or laptop. Browse a model on Printables.com, open it in EasyPrint, and send it straight to your CORE One+.

Six engineering choices that set the CORE One+ apart.

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.

Fully Enclosed CoreXY Architecture

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 for vibration at high speeds.

Active Chamber with Smart Ventilation

The printer's enclosed chamber heats up to 55 °C. The system monitors temperatures at all times and adjusts automatically to create the best environment for any material you choose. Optional HEPA filtration integrates directly into the enclosure for offices and schools.

Nextruder: Precision at Every Layer

Nextruder is our next-gen print head featuring a precise Load Cell sensor that measures force at the nozzle tip - the nozzle itself becomes the probe. Because it is physical, it cannot be confused like optical sensors. Plus, 360-degree cooling means steep overhangs print cleanly without supports and nozzles (0.25 mm to 0.8 mm) are swappable in seconds without tools.

Robust Steel Exoskeleton

All-steel exoskeleton — the enclosure is structural, not an accessory. Exceptional rigidity at high speeds. Nothing is glued. Everything comes apart with a screwdriver. Designed for modders and tinkerers — replacement parts stocked for years.

Compact Footprint, Large Volume

50% less desk space than an MK4S inside an enclosure, yet 30% more print volume (250 × 220 × 270 mm). That efficiency matters whether you're fitting one printer on a desk or 600 into a print farm — which is exactly what Prusa Research does at their own facility.

Open‑Source Hardware & Firmware

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.

The key to successful prints

Active Chamber Temperature Control

Engineering materials warp when they cool unevenly - corners lift, layers separate, prints fail. CORE One+ prevents this with a compact chamber that hits up to 55 °C, creating a stable environment. And the best thing? While other printers need you to open the door for printing low-temp materials (like PLA), you can keep the CORE One+ door closed thanks to smart chamber ventilation.

Your Printer, Your Rules

Experience a printing platform designed with transparency, repairability, and your creative freedom in mind. You own your 3D printer, not just a license to use it.

Any Filament, Any Brand

Prusa printers work with any standard 1.75 mm filament. Use Prusament for tested quality or pick your favorite brand. PrusaSlicer includes over 200 ready-made profiles, and you can always create your own for new materials.

Connection is Optional

Print via USB drive or your local network - no internet connection required. Optional Prusa Connect adds remote monitoring and print farm management. You don't have to connect the printer to the internet; not even once.

Open‑Source Files

The firmware source code is on GitHub and CAD files are published at Printables.com. You can inspect, modify, or build your own version. Tinkering is optional, but if you want to mod your printer, you have all the resources.

Free Software, No Tiers

PrusaSlicer, EasyPrint, Prusa Connect, the Prusa App, and every firmware update - included with the printer and free. No forced ads, no hidden subscription tiers.

Right to Repair

Nothing is glued. Everything comes apart with a screwdriver. We keep spare parts in stock for years after release. A worn nozzle (after hundreds of print hours) is a $20 swap, not a reason to worry.

Upgradability

Whenever it's even remotely possible, Prusa offers its customers a clear and transparent upgrade path. When an improved model comes out, you can usually upgrade the printer you have at home.

What Makes Prusa 3D Printers Secure

Designed and Built in the EU

Prusa retains full control of its manufacturing and supply chain. All critical electronics, including the custom mainboard for this edition, are manufactured on its own PCB production line in Prague, Czech Republic, EU.

Open Source Assets

Prusa's firmware and PrusaSlicer (slicing software) are open-source which means THE ENTIRE source code is available on Github for anyone to inspect it.

The Printer Belongs to You

The true offline capability ensures your machine will never turn into a useless brick. If a cloud service goes down, your internet drops, or a company changes its terms of service, your printer will continue working exactly as it did on day one. You own the hardware, not just a license to use it.

100% Privacy: Offline Mode without Compromise

You don’t have to connect the printer to the network - not even once, and you can still enjoy the full experience without any drawbacks. The printer can be configured and operated offline, including slicing and installation of firmware updates. The Wi-Fi module can be easily unplugged for environments with the highest level of security.

Prusa believes that whether you are developing a next-generation spacecraft or simply printing toys for your children, no organization should be interested in collecting information about your prints or the environment in which your printer is located.
Wir sind der Überzeugung, dass – ganz gleich, ob Sie ein Raumschiff der nächsten Generation entwickeln oder einfach nur Spielzeug für Ihre Kinder drucken – keine Organisation daran interessiert sein sollte, Informationen über Ihre Drucke oder die Umgebung Ihres Druckers zu sammeln.
