Prusa CORE One+ 3D Printer

A fast, enclosed CoreXY workhorse built to last — with active chamber temperature control for advanced materials, factory-tuned profiles for consistent results, and Prusa’s “right-to-repair” design philosophy.

 
Prusa CORE One+ enclosed CoreXY 3D printer
Enclosed CoreXY Active chamber control (up to 55°C) Build volume 250×220×270 mm Input Shaper + factory-tuned profiles

Tip: Add the optional filtration system if you plan to print ABS/ASA/nylons regularly in shared spaces.

High speed, high accuracy — with the enclosure and thermals you need for real functional prints

CORE One+ pairs a rigid CoreXY platform with the Prusa Nextruder, high-flow nozzle, and actively managed chamber environment. The result: reliable prints in everyday PLA/PETG, plus the stability needed for tougher materials like ASA/ABS, PC and PA (nylons) when configured appropriately.

What's new in CORE One+: quality-of-life hardware updates plus accumulated firmware refinements for smoother operation and a more set-and-forget experience:

  • Automatic top vent operation (opens for low-temp materials, closes for high-temp materials)
  • Easier flexible filament loading with a redesigned insertion point
  • Bayonet-style spoolholder for multiple spool sizes; drybox-friendly direct feed

Speed without the penalty: CoreXY kinematics + Input Shaper + high-flow nozzle let you print fast with mainstream filaments (PLA/PETG) while keeping surfaces clean and dimensions accurate.

  • Factory-tuned profiles reduce the trial-and-error most printers require at higher speeds
  • Nextruder + 360° cooling helps support challenging geometry and steep overhangs
  • Loadcell-based first layer calibration for repeatable starts

Built for advanced materials: the enclosed, actively controlled chamber (up to 55°C) improves thermal stability and reduces warping for materials like ASA/ABS, PC and PA (nylons) when configured appropriately.

  • Automatic ventilation strategy helps keep PLA reliable even with the door closed
  • Optional filtration is recommended for frequent high-temp printing in shared environments

Seamless Workflow (Software + Remote Management)

CORE One+ is designed to feel cohesive: slicing, profiles, remote printing, and monitoring are part of the same workflow. You can print via USB drive, LAN, or over the internet using Prusa Connect and the Prusa mobile app.

  • PrusaSlicer: powerful slicer with in-house tested printer + material profiles
  • Prusa Connect: secure remote management for one printer or a farm
  • Prusa App (iOS/Android): send jobs, monitor prints, manage printers on the go
  • Connectivity: Ethernet built-in; Wi-Fi via included optional ESP module (NFC receiver supported)

Upgrades & Add-ons

Popular options

  • MMU3 support: print with up to five filaments/colors (single nozzle workflow)
  • Optional in-chamber camera: USB-C camera add-on for remote monitoring
  • Optional filtration: HEPA / advanced filtration add-ons for reduced odor/particles during high-temp printing
  • GPIO hackerboard: for advanced automation and external device control via G-code
  • Accelerometer support: for calibrating Input Shaper on modded setups

High Temp Hotend upgrade (optional)

An optional quick-swap HT hotend upgrade is available for the CORE One family to unlock higher-temperature printing for specialized engineering materials (ideal for teams pushing into high-performance polymers).

Who It's For

Engineering, functional parts, and small production

  • Teams that need repeatability: fixtures, brackets, housings, jigs, adapters
  • Print farms that value remote management and consistent profiles
  • Workshops that want a compact enclosed machine with real thermal control

Education and makers that want fewer surprises

  • Reliable first layers via loadcell calibration
  • Easy maintenance: serviceable design and long-term parts availability mindset
  • Upgradeable ecosystem: expand capability instead of replacing the printer

FAQ

1) Is CORE One+ good for ABS/ASA and nylons?

Yes — the enclosed design and actively controlled chamber (up to 55°C) improves thermal stability and helps reduce warping. For frequent high-temp printing in shared areas, consider adding filtration.

2) Can I still print PLA with the door closed?

CORE One+ is designed to manage chamber conditions for both low-temp and high-temp materials (including automated vent behavior), helping PLA remain reliable while keeping the printer enclosed.

3) What is the real build size?

250 × 220 × 270 mm. If you tell us your largest parts, we can confirm fit and suggest orientation/support strategy.

4) Does it support multi-material printing?

Yes — it supports Prusa’s MMU3 add-on (up to five filaments in a single-nozzle workflow). There are also future expansion paths designed for broader multi-material capability.

5) How do I monitor prints remotely?

Use Prusa Connect and the Prusa mobile app over LAN/internet. An optional in-chamber camera add-on is available for visual monitoring.
