Industry Impressions Fast "Prusa literally transformed their classic i3 printer into a Core XY machine with more speed and all the outstanding quality we expect from an industry leader." Tom's Hardware Precise "As you might expect, the print quality is absolutely divine! I've tested this across a range of filaments, and the results have been consistently impressive." Sam Prentice Best "This is just about the best 3D printer you can get right now." TechRadar What Does It Cost to Run? The printer purchase is the biggest expense. After that, it's just filament and the occasional spare nozzle or print sheet. ~$25/kg Filament (PLA) One kilogram prints dozens of objects. ~$20 Nozzle replacement Lasts hundreds of print hours. Replacement takes 1-2 minutes. ~$37 Print Sheet Replacement Lasts hundreds of print hours. Print sheets are double-sided. $0 Software & updates PrusaSlicer, EasyPrint, Prusa Connect, Prusa App, and updates - free. Summary: Most users spend $25–50/month on filament. Everything else (PrusaSlicer, Prusa Connect, firmware updates) is free. A CORE One+ bought today will still be printing strong years from now. Highlights: No forced subscriptions | Free software & firmware updates | No annoying cartridge locks (like with ink printers) One spool = over 80 different objects! 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!

The pre-built CORE One+ delivers beautiful prints within 10 minutes from unboxing. from $1,499 Configure & Buy Accessories to consider 1080p Camera with Night Vision Install an optional 1080p camera for remote print monitoring. Connects using a USB-C cable directly into the motherboard. Advanced Filtration System Useful when you print materials such as ASA and other materials that produce an increased number of ultra-fine particles and fumes. Additional nozzles & sheets Depending on what you want to print, consider adding a hardened nozzle (for abrasives) or smaller nozzles for detailed models. Features & Architecture 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 vibration at high speeds, with travel speeds reaching 600 mm/s. 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. Because it is physical, it cannot be confused like optical sensors. Plus, 360-degree cooling means steep overhangs print cleanly without supports. 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. 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.

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.
