Prusa CORE One 3D Printer (1st Edition) - Ex Demo

The original fully enclosed CoreXY CORE One with active chamber temperature control, offered as an ex-demo unit well below the price of a new CORE One+.

About This Ex-Demo Unit

 

This is a first-edition Original Prusa CORE One that has been used as a demonstration printer in our store. It is the original CORE One, not the newer CORE One+, so the top vent is opened and closed by hand (the printer prompts you at the start of each print), and it has the original filament insertion point and spool holder.

It shares the CORE One+'s build volume, Nextruder, CoreXY motion system and actively heated chamber, and both run the same firmware, so PrusaSlicer profiles and G-codes work on either printer.

Please contact us before purchase if you would like to know more about this unit's condition or what's included.

Smooth, Accurate, Fast

 

The rigid CoreXY motion system with Input Shaper and Phase Stepping keeps surfaces clean through rapid direction changes, while 360-degree part cooling handles steep overhangs and bridges. The Nextruder's loadcell calibrates the first layer automatically before every print, so there is no manual levelling.
