The Prusa CORE One+ by Josef Prusa is a high-performance fully enclosed CoreXY 3D printer with active temperature control designed fortop 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.

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, saving both time and material.
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, delivering best print quality, and 15 hours faster speed 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+ by Josef Prusa?
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 and active temperature control enable flawless printing of PLA, PETG, and TPU — even with the door completely closed! The extruder now automatically opens the vent for low-temp materials and closes it for high-temperature materials, ensuring the optimal thermal environment and creating a true "set-and-forget" experience.
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. The redesigned filament insertion point with a new loading lever makes feeding flexible filaments quick and simple.
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 offers top-class manufacturing precision, perfect color consistency, and 20 materials from PLA to PC-CF. Every Prusament material has an in-house tested profile in PrusaSlicer, ensuring consistent results. Third-party filaments are also compatible, needing only minor profile tweaks for optimal results. In total, the PrusaSlicer contains 200+ pre-configured profiles.
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 ofEthernet 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.

What is the design and build quality of the Prusa CORE One+?
The Prusa CORE One+ is made to last. Its 22.5 kg all-steel frame ensures high rigidity and stability during fast prints.
The exterior features powder-coated metal and tinted acrylic panels in Josef Prusa's signature black and orange color scheme, a design well known hallmark of Original Prusa 3D printers in the 3D printing industry.
The Prusa CORE One+ won a Red Dot Award for its design, combining form and function. It uses 10mm Y-axis rods, an X-axis linear rail, and three Z-axis lead screws — Prusa’s most constrained Z-axis system yet.
Recessed sides reduce chamber volume for faster heating and improve access. The right-side recess includes a modular bayonet-style spool holder compatible with 2kg spools and dryboxes, plus a new loading lever that makes feeding flexible filaments quick and simple.
The left-side pocket provides customizable tool storage with magnetic mounting points. The front door opens from either side and locks at 90° or 180° for flexible access. It also features reinforced hinges for smoother operation and better sealing.
The top panel features an automatically controlled ventilation system. The extruder now automatically opens the vent for low-temp materials (PLA/PETG) and closes it for high-temperature materials (ABS/ASA), ensuring the optimal thermal environment without user intervention.
The Prusa CORE One+ uses Prusament PC-CF for key printed parts, offering greater durability than PETG in heated environments. Its Core XY machine architecture features 0.9° stepper motors for finer motion resolution and optimized fan profiles (aided by the new automated vents) for smoother, quieter operation than standard 1.8° motors.
All components can be fully disassembled with standard tools — no glue or permanent fixtures — making maintenance and upgrades easy.
The front RGB light shows printer status at a glance — especially helpful in multi-printer setups. This and other design choices reinforce the CORE One+’s reliability and serviceability.

Bondtech INDX Upgrade
The Bondtech INDX system is a new approach to multi-material printing. Instead of a filament switcher like the MMU3, it uses one active “Smart Head” with induction heating that quickly picks up lightweight, wireless passive tools. This enables up to 8 materials with tool changes in seconds, near-zero waste (no purge tower), and rapid nozzle heating/cooling to reduce stringing.
Prusa MMU3 Upgrade
For traditional multi-material printing, the MMU3 remains available. It mounts to the CORE One+ and automatically loads, purges, and cuts up to five filaments via a compact planetary gearbox selector. PrusaSlicer firmware integration supports wipe tower control and color-by-layer optimization to reduce waste during transitions.
The redesigned selector uses a compact planetary gearbox for faster, more reliable material changes. An upgraded sensor pauses prints on filament run-out or tangles.
Firmware integration with PrusaSlicer enables wipe towers, purge control, and color-by-layer tools to minimize waste during color changes. For example, a globe print used the MMU3 to manage multiple colors in a single pass.
Purge Tower Example on the right side:
HT Hotend Upgrade to Print at 400 °c
The HT Hotend Upgrade turns the CORE One+ into a high-temp, industrial-ready printer by boosting maximum nozzle temperature to 400°C. This enables advanced polymers like PEKK-CF (aerospace structural parts), PPS-CF (automotive/fluid handling), PPSU (medical sterilization), and PPA-CF (metal-replacement connectors). It also improves adhesion for common engineering materials such as ASA, PA11, and PETG — up to 30% — by enhancing thermal bonding. The upgrade installs tool-free in under a minute, making it easy to switch between standard and high-temperature printing.
Print Surfaces
The Prusa CORE One+ supports all Prusa print sheets — Smooth PEI, Textured, Satin, and PA Nylon — offering optimal adhesion without Z-offset changes. Extra Prusament spools ensure consistent results using pre-configured PrusaSlicer profiles.
Community Add-Ons
The Prusa CORE One+ supports customization with magnetic mounting points on its metal enclosure. The left-side recess fits storage add-ons, and the top panel accepts aftermarket filters. Users share mods like dry boxes, tool holders, and camera mounts on Printables.com.
