What's New in the CORE One+ (Gen 2)?

The second generation builds on the CORE One+ platform, retaining its CoreXY motion system and material compatibility while introducing three practical improvements: faster print starts, cleaner first layers and smoother-looking surfaces.

Faster Print Starts with Redesigned Heatbed Mounting

The redesigned heatbed mounting system, including new expansion joints, helps the build plate remain flat as it heats. This removes the separate heat-absorption waiting period previously required before printing materials with bed temperatures up to 85°C. The bed also reaches a stable shape sooner when working with higher-temperature materials.

Cleaner First Layers with Automatic Nozzle Wiping

Filament residue left on the nozzle after a previous print or during priming can create blobs and marks on the first layers. The CORE One+ (Gen 2) automatically wipes the nozzle during its startup sequence, helping prevent unwanted residue from affecting the print surface.

Smoother Surfaces with GT1.5 Belts

Fast CoreXY movement can sometimes produce faint, repeating surface patterns as belts flex during direction changes. The GT1.5 belts used in Gen 2 reduce this flex, making these patterns finer and less noticeable, particularly on large flat or curved surfaces.

Fully Enclosed CoreXY 3D Printer Architecture

The CORE One+ (Gen 2) uses a CoreXY motion system in which two fixed motors move the lightweight print head while the build plate travels only along the Z axis. Keeping moving mass low helps the printer combine high-speed movement with precision. Input Shaper firmware compensates for vibration to reduce ringing and other motion-related artefacts.

Its enclosure is also its structural frame. The all-steel exoskeleton provides rigidity without relying on a separate frame with a cosmetic cover attached. This robust construction helps keep the printer stable during fast movements and accelerations.

The machine is designed to be repairable: internal components are not glued together, and the printer can be disassembled using basic tools. Replacement parts are kept available well after a model's release.

Active Heated Chamber and Smart Ventilation

The actively heated chamber reaches up to 55°C and is continuously monitored. The printer adjusts its environment according to the loaded material, helping maintain stable conditions throughout a print.

For low-temperature materials such as PLA and PETG, the printer automatically opens its top vent to help prevent chamber overheating. For higher-temperature materials, it closes the vent to retain heat and maintain a warmer printing environment.

An optional Advanced Filtration System integrates into the enclosure and combines HEPA filtration with activated carbon to help reduce particles and fumes released into the room. This accessory is sold separately.

Nextruder with Automatic First-Layer Calibration

The Prusa Nextruder is a direct-drive print head designed for precise and consistent extrusion. Its Load Cell sensor measures physical force at the nozzle tip, allowing the nozzle itself to act as the probe during automatic first-layer calibration and bed leveling.

Because the system measures physical contact rather than relying on optical sensing, calibration is not affected by lighting conditions or the colour and finish of the print sheet. This makes first-layer setup automatic and helps reduce manual adjustment.

Precision Extrusion and 360° Part Cooling

The Nextruder combines a planetary gear system with a 10:1 gearbox ratio, an all-metal hotend with an aluminium heatsink and a high-performance turbine fan. Its 360° part-cooling system helps produce clean overhangs and detailed parts.

The tool-free quick-swap nozzle system supports nozzle diameters from 0.25 mm to 0.8 mm. Switch between fine-detail printing and higher-flow applications without a lengthy disassembly. The printer comes with a high-flow brass CHT 0.4 mm nozzle installed and also supports hardened-steel nozzles for abrasive and fibre-filled filaments.

Easy Filament Loading and Flexible Spool Options

A redesigned filament insertion point makes loading flexible materials such as TPU easier. The bayonet-style spoolholder accommodates a range of spool sizes and supports direct feeding from a drybox setup. Standard 1.75 mm filament from Prusament and other manufacturers can be used.

Compact Design with a 250 × 220 × 270 mm Build Volume

The enclosed CORE One+ (Gen 2) is designed to make efficient use of desk and workshop space. Despite its compact footprint, it offers a 250 × 220 × 270 mm build volume, including a generous Z height for taller prints. It is suitable for a single workstation or a multi-printer production environment.

3D Printing Software and Remote Printer Management

The CORE One+ (Gen 2) is compatible with Prusa's software ecosystem, providing tools for preparing prints, managing materials and monitoring machines.

• PrusaSlicer: Free, open-source slicing software with more than 200 factory-tuned material profiles, organic supports, variable layer height and paint-on seam placement.
• EasyPrint: A web-based app for sending models from Printables.com to the printer using a phone, tablet or browser.
• Prusa Connect: Browser-based remote monitoring and multi-printer management.
• Prusa App: Mobile printer control and direct Printables integration for iOS and Android.

The printer accepts standard 1.75 mm filament and is not restricted to Prusament. Users can select third-party materials or create custom profiles. PrusaSlicer, EasyPrint, Prusa Connect, the Prusa App and firmware updates are available without a required subscription.

Optional Camera, Filtration and Multi-Material Upgrades

The standard CORE One+ (Gen 2) can be expanded with separately available accessories. These are optional upgrades and are not included with the base printer unless specified.

Optional 1080p Camera with Night Vision

An optional 1080p camera with night vision can be installed inside the chamber for remote print monitoring. It connects directly to the motherboard through USB-C and can stream the print to Prusa Connect and the Prusa App.

Optional Advanced Filtration System

The optional Advanced Filtration System, designed for Prusa Research by Alveo3D, integrates into the printer enclosure. It is intended to reduce the amount of ultra-fine particles and fumes released into the surrounding room when printing materials that produce emissions.

Optional INDX Multi-Material Toolchanger

The CORE One+ (Gen 2) supports the separately available INDX multi-material toolchanger as a later upgrade. INDX can enable printing with up to eight materials or colours in a single job. This product listing is for the fully assembled standard printer without INDX; the toolchanger requires a separate upgrade kit.

The printer can also be extended with the optional MMU3 multi-material system.

Materials and Applications

The actively heated chamber and versatile Nextruder make the CORE One+ (Gen 2) suitable for a broad range of materials and applications.

• Everyday materials: PLA, PETG, Flex/TPU, PVA, PC, PP, CPE and PVB.
• Engineering materials: ASA, ABS and PA (Nylon), supported by the heated chamber.

From detailed hobby models and cosplay props to functional prototypes, workshop tools, replacement parts and small production runs, the CORE One+ (Gen 2) is designed to handle a wide range of 3D printing projects. Its heated chamber helps reduce warping when printing materials that are more challenging on open-frame machines.

Designed for Beginners, Makers and Professional Workflows

Automatic calibration and a straightforward setup make the CORE One+ (Gen 2) approachable for first-time 3D printer owners. At the same time, its material range, open-source platform, repairability and remote management features make it suitable for experienced makers, workshops and businesses operating multiple printers.

The printer is designed and manufactured in the European Union at Prusa Research facilities in Prague, Czech Republic. Prusa also produces its custom mainboard on its own PCB production line, maintaining direct control over important parts of the manufacturing process.

Repairable, Upgradeable and Open-Source Design

Prusa publishes the printer's CAD files and firmware source code, allowing the hardware and software to be inspected, modified and rebuilt. The CORE One+ (Gen 2) is designed without a locked bootloader or mandatory cloud dependency. It can be set up, prepared for printing and updated offline, and its Wi-Fi module can be unplugged when network connectivity is not desired.

The open and repairable design supports long-term maintenance and upgrades. Firmware improvements across the CORE One lineup can bring refinements to print profiles, motion control and sensors. The INDX toolchanger is one example of an upgrade that can add new capabilities without replacing the printer.

Low Ongoing Costs and No Required Subscription

There is no cartridge-style filament lock-in or subscription required to keep printing. Nozzles typically last hundreds of print hours and can be replaced in minutes. The double-sided print sheet can be flipped when one side becomes worn, helping extend its useful life.
