CORE One
The Prusa Research CORE One is a FDM 3D printer released in 2025 by Prusa Research, with a build volume of 250×220×270 mm and MSRP of €1,349. Compatible with MMU3 (5 slots). Enclosed chamber. Active heated chamber. Claimed maximum speed: 600 mm/s.

Our take on the CORE One
The CORE One was Prusa's move to an enclosed CoreXY: a chamber with active temperature control up to 55 °C, a 120 °C bed and a 290 °C nozzle, with a 250 × 220 × 270 mm build volume. It's aimed at people who want to print engineering materials (ABS, ASA, polycarbonate) with Prusa's philosophy: open software, repairable parts and a huge community.
Against the enclosed machines in its bracket, like the Bambu Lab X1 Carbon or the Creality K2 Plus, it doesn't compete on speed figures but on chamber heat control and ecosystem: it takes the 5-filament MMU3, slices in PrusaSlicer or OrcaSlicer, and uses quick-swap nozzles.
An honest heads-up: when we checked Prusa's site (October 2026), the CORE One page already led to the CORE One+ (Gen 2), and the original was no longer in the current line-up. If you find one, it's likely leftover stock or second-hand: compare it with its successor before buying. We have a longer analysis of this machine.

What materials can the CORE One print?
This comes from four facts on its spec sheet: the nozzle reaches 290 °C, the bed 120 °C, and the machine is enclosed with a direct-drive extruder. Those four facts decide most of the list: nozzle temperature sets the ceiling on what you can melt, the bed decides whether the first layer sticks, the enclosure keeps large parts from warping, and the extruder type rules flexibles. We don't test the machine — this is guidance derived from verified data, not a guarantee.
In short: it prints PLA, PETG, TPU (flexible), ABS, ASA, Nylon (PA), Policarbonato (PC) without a fight.
| Material | Prints it? | Why |
|---|---|---|
| PLA | Yes | Yes. PLA has no special needs: any FDM printer like the CORE One prints it out of the box. |
| PETG | Yes | Yes. With a nozzle up to 290 °C and a bed up to 120 °C it comfortably meets PETG's needs. |
| TPU (flexible) | Yes | Yes. It has a direct-drive extruder, ideal for flexibles; prints TPU well (go slow). |
| ABS | Yes | Yes. Nozzle up to 290 °C and an enclosure: it contains ABS's warping and fumes. |
| ASA | Yes | Yes. Nozzle up to 290 °C and an enclosure: it contains ASA's warping and fumes. |
| Nylon (PA) | Yes | Yes. It reaches 290 °C and is enclosed: it prints Nylon (dry it well first). For carbon-fibre variants, use a hardened-steel nozzle. |
| Policarbonato (PC) | Yes | Yes. Nozzle up to 290 °C and an enclosure with active heating: suitable for PC. For carbon-fibre variants, use a hardened-steel nozzle. |
