• Plug and 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: 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.
• Compact Footprint, Large Volume: 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: 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!
• Ready for the Future: When you buy the CORE One, you’re investing into a platform that will continue to grow over time, rather than something that you’ll have to replace in a year or two. Prusa printers are well known for their exceptional reliability, durability and long life cycle. We offer excellent post-launch support with regular firmware and even hardware updates to expand your printer’s capabilities even years after launch. And when a new machine comes out, we publish an upgrade kit.
