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.

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.

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.

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

The CORE One+ is here to surprise you with its infinite usability. Be sure to add a couple of Prusament spools to your order, so you can try different things!

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

Engineering & Safety
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.
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+.


You can print A LOT with a single spool of filament.
One kilogram of filament prints one kilogram of objects - but that's a bit difficult to imagine. Check out the photo below to see how many things we printed with a single spool of Prusament - it's over 80 different objects!
Starting a 3D print is as simple as pushing a button. But if you're curious and want to explore more of the 3D printing world, we got you covered!

All our printers come with a free printed handbook covering everything from the basics to advanced workflows. You can even download it as PDF and read it before your printer arrives.

Assembled CORE One+ comes with a free Prusa Academy Course "3D Printing and Modelling for Beginners". With our courses, you will become a master of 3D printing overnight!

CORE One+ works perfectly out of the box. Still, you may want to consider these accessories to level up your 3D printing game.
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.

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.

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 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.
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.

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.

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.
エンジニアリング材料は不均一に冷却されると反りが発生し、角が浮いたり、レイヤーが剥離したりして、プリントが失敗することがあります。CORE One+は、最大55 °Cに達するコンパクトなチャンバーによって安定した造形環境を作り、こうした問題を防ぎます。さらに優れているのは、他のプリンターではPLAなどの低温素材をプリントする際にドアを開ける必要があるのに対し、CORE One+ならスマートなチャンバー換気機能により、ドアを閉じたままプリントできることです。

The printer purchase is the biggest expense. After that, it's just filament and the occasional spare nozzle or print sheet.
One kilogram prints dozens of objects.
Replacement takes 1-2 minutes
Print sheets are double-sided - if one side is worn, swap to the other side

From the heart of Europe to the entire world
Prusa Research is a 3D printer manufacturer based in Central Europe - in Prague, Czech Republic. It is now a team of over 1,000 people with a brand new factory opened in Delaware, USA. But it started as a one-man project.
In 2010, Josef Průša designed an open-source printer that hobbyists could actually afford. It caught on. Years later, the company is still in Prague, still independently owned, and still making printers the same way - designed in-house, built to last, and shared openly with the community that helped build them. A lot has changed in 3D printing. Not everything needs to.
Choosing your first 3D printer is an important decision, and we understand you may have some additional questions. If you don't find an answer here, let us know via Live Chat - we'll be happy to help! :)
All three share the same Prusa ecosystem, firmware, and slicer. The differences are in size, enclosure, and target use case.
