The Prusa CORE One is a high-performance enclosed 3D printer featuring CoreXY kinematics for 15–20% faster speeds than the MK4S, while maintaining Prusa’s print quality. Its active chamber control (up to 55°C), upgraded Nextruder with 360° cooling for support-free 75° overhangs, and a steel exoskeleton support reliable printing with materials like ASA, ABS, PC, and nylon. Compact yet spacious with a 250×220×270mm build volume, it suits beginners to professionals, offering safety features, easy maintenance, and award-winning design recognized by the Red Dot Award and All3DP.
What is the print quality and performance of the Prusa Core One, as confirmed by test prints?
The Prusa CORE One delivers consistent, high-quality prints across materials using a precision CoreXY system. It features 10mm Y-axis rods, an X-axis linear rail on a steel extrusion, and three Z-axis lead screws — Prusa’s most constrained Z-axis yet. Dimensional accuracy is excellent, with test prints measuring 100.03mm (X), 100.05mm (Y), and 100.00mm (Z) against 100mm targets. Its 0.9° stepper motors offer finer resolution and smoother, quieter motion than standard 1.8° motors.
3D X-ray CT inspection of a complex part showed the central bore and main body were within ±0.100mm of nominal dimensions. However, several mounting features and edges deviated by ±0.400–0.600mm, especially on lower tabs and edge transitions. These deviations, shown in orange-to-red on the CT map.

Inspection Report:
The Prusa CORE One’s load cell-based auto bed leveling taps the surface for precise measurement, ensuring perfect first layers on any build plate without manual adjustment.
The upgraded Nextruder’s 360° cooling allows printing of 75° overhangs.
The enclosed chamber with active temperature control prevents warping and improves adhesion for shrink-prone materials. For ASA, it preheats to 40°C and can reach 55°C during printing.
Real-world testing shows the Prusa CORE One’s performance — a Speed Benchy printed in 28 minutes using 0.25mm layer height, 2 perimeter walls and 10% infill delivered excellent results. Indeed, assembled Core One is the fastest printer by Prusa Research!
A fishing lure printed in ASA finished in 1 hour 17 minutes at 0.2mm layer height, with smooth, warp-free results. A full-size Crocs shoe in 40D TPU printed in 21 hours without supports — 15 hours faster than the MK4.
The Prusa CORE One delivers consistent quality across its full build height — unlike bed-slinger designs that lose stability when tall. With speeds up to 600mm/s and input shaping for vibration control, it prioritizes reliability over raw speed. Pre-tuned profiles for 200+ filaments in PrusaSlicer ensure strong performance out of the box.
Which filaments can you use with the Prusa Core One?
The Prusa CORE One supports over 12 filament types, including PLA, PETG, TPU, PVA, PP, CPE, and PVB, with no special modifications. Its 290°C nozzle and 120°C bed handle most materials reliably.
The automatic ventilation system maintains 20–30°C for PLA, PETG, and TPU, even with doors closed. A top vent lets fans pull in cooler room air as needed.
With the optional Advanced Filtration System, the Prusa CORE One prints ABS, ASA, HIPS, PC, and Nylon reliably. Its enclosed, actively heated chamber (up to 55°C) prevents warping and improves adhesion.
The Prusa CORE One prints TPU from 90A to 95A hardness reliably, aided by the Nextruder’s high-torque planetary gear system.
TPU Print Sample:
The Prusa CORE One comes with a 0.4mm brass CHT nozzle, ideal for standard filaments but unsuitable for abrasives. For carbon fiber or metal-filled materials, a hardened steel nozzle is recommended. An adapter allows use of E3D V6-compatible nozzles for added flexibility.
Prusament filaments work seamlessly with the Prusa CORE One, supported by 200+ pre-configured profiles in PrusaSlicer. Third-party filaments are also compatible, needing only minor profile tweaks for optimal results.
What is the build volume of the Prusa Core One?
The Prusa CORE One offers a 250 × 220 × 270 mm build volume — 30% larger than the MK4S, mainly due to 50 mm more Z-height. Its CoreXY design ensures consistent quality across the full height, unlike bed-slingers that lose stability at taller prints.

The Prusa CORE One’s compact design uses 50% less space than the MK4S in an enclosure while offering a larger build volume. It supports all Prusa print sheets — smooth PEI, textured, and satin — for material versatility. With the MMU3, a prime tower is used, reducing available space for large or multi-part prints.
The Prusa CORE One’s tall 270mm Z-height supports prints like vases, figurines, and helmets — one red PLA helmet printed in 2 hours 10 minutes.
What is the difference between the Prusa Core One, Bambu Lab P2S, Bambu Lab X1 Carbon, Bambu Lab H2S, Creality K2 Plus?
Prusa CORE One — Best when you need stable enclosure control for ABS/ASA/PC (automatic preheat to ~40 °C and ~50 °C during prints, without opening the door for PLA), consistently accurate first layers from the load-cell system, practical Z-height (270 mm), and open connectivity (local USB/Ethernet and user-flashable firmware).
In contrast:
- Bambu Lab X1 Carbon — Often matches Core One print times and can be ~20% faster in some cases, but does so with weaker temperature control on fast PLA passes; usable XY area is effectively similar (front-of-bed is used for calibration/filament cutting), while Prusa keeps a taller Z (270 mm vs 256 mm). Additionally, the Bambu Lab closed ecosystem approach limits the use of third-party tools such as OrcaSlicer.
- Bambu Lab P2S — Wins on price and speed/flow; loses to Prusa on wired networking (no Ethernet), closed ecosystem and shorter Z-axis (256 mm vs 270 mm).
- Bambu Lab H2S — Wins on volume (340³ mm), active chamber heat (to ~65 °C) and peak speed/flow; loses on lack of Ethernet and closed ecosystem.
- Creality K2 Plus — Big cube (350³ mm) on paper, but multiple units showed severe Z-banding on tall prints (~8–12 in) and build-plate surface shedding, undermining reliability for production-height parts.
