The Prusa CORE One+ by Josef Prusa is a high-performance fully enclosed CoreXY 3D printer with active temperature control designed for top print quality and speed (printing 15–20% faster than the MK4S). 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. It integrates key hardware quality-of-life improvements adopted from the CORE One L, combined with all firmware updates developed over the entire lifespan of the CORE One, resulting in even better print quality and smoother operation right out of the box. Compact yet spacious with a 250×220×270mm build volume, it suits beginners to professionals to print farm owners.

What is the print quality and performance of the Prusa CORE One+ 3D printer?

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.

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.

Printer Model Build Volume (mm)

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.

Bottom-Line:

  • Buy Prusa CORE One+ for controlled chamber thermals, repeatable first layers, taller Z, secure connection over Ethernet, and the open-source approach.
  • Buy the Bambu Lab P2S for the best speed at the best price, if the closed, cloud-based ecosystem is not a concern.
  • Bambu Lab H2S for max volume + active heat, if the closed, cloud-based ecosystem is not a concern.
  • Avoid Creality K2 Plus, if you are not ready to fine-tune the machine for consistent results.
  • Avoid the Bambu Lab X1 Carbon, unless you buy it at a lower price than the Bambu Lab P2S.

Bundle includes four CORE One powder-coated print sheets: Textured, Satin, PP, and PA Nylon.

$280 Prusa Core One sheets stack including smooth PEI, textured, satin, PP, and PA nylon with branding, designed for the 3D printer.
Smooth PEI Print Sheet

Removable spring-steel sheet with a smooth, double-sided PEI surface for MK52 heatbeds with embedded high-Curie magnets. Optimized for PLA, offers strong adhesion with most materials, and leaves a smooth bottom finish. Notes: don’t clean with IPA before printing PETG (a release agent may be needed), and use glue stick for flexible filaments.

$49 Prusa Core One PEI sheet with grid lines, brand logo, and safety icons, used for 3D printing surfaces with precise measurements and reliable adhesion.
PA Nylon Powder-coated Print Sheet

Powder-coated spring-steel print sheet with a special surface finish for polyamide (PA) filaments, especially Prusament PA11 Carbon Fiber Black. Designed to improve adhesion where PA tends to stick poorly to standard textured or satin sheets. Care: clean only with pure water—IPA or acetone will quickly deteriorate the surface. Glue stick isn’t required or recommended. For greasy spots, use water with a drop of dishwashing detergent.

$83 Prusa Core One print bed with branding; black and red design, includes instructions for use, likely used in professional 3D printing.
PEI-Ultem sheet

Powder-coated spring-steel print sheet with a lightly textured matte/satin finish, offering performance between smooth and textured sheets. Provides strong, balanced adhesion—especially for PLA and PETG—and is compatible with many other filaments (including ABS, ASA, FlexFill 98A, and Polycarbonate). Most materials can be printed without a separation layer; for frequent Polycarbonate printing, apply a glue-stick layer to prevent possible sheet damage. Notes: never clean with acetone, and adjust Live-Z when switching between sheet types.

$66 Prusa Core One print bed with branded logo, flexible steel sheet, smooth black surface, designed for 3D printing with precision and durability.
Textured Powder-coated Print Sheet
