Prusa introduces CORE One+ as a revised version of CORE One

Prusa Research has introduced the CORE One+, an advanced version of the CORE One launched in 2024. The model is aimed at users who want a stable CoreXY printer with a focus on reproducible results and expandable hardware. The focus is not on a new basic design, but rather a combination of firmware maturity and targeted hardware adjustments designed to simplify the workflow.

The basis of the CORE One remains unchanged. The printing mechanism, build volume, and basic material support are the same as the previous model. Existing extensions can also continue to be used. The manufacturer is thus pursuing an approach of gradually expanding an existing system rather than introducing new generations with incompatible hardware. According to the manufacturer, existing CORE One devices will continue to be supported and do not necessarily need to be upgraded.

The Plus version initially bundles all software updates released since the market launch. These are intended in particular to reduce vibration influences and smooth movement sequences. This is supplemented by several hardware changes that were previously developed for the larger CORE One L. The key innovation is an automatically controlled housing ventilation system. The Nextruder opens or closes the ventilation depending on the material loaded. Low-temperature filaments such as PLA or PETG benefit from open ventilation, while it remains closed for materials such as ABS.

Further adjustments relate to handling. A redesigned filament inlet with a manual switch is intended to make it easier to load flexible materials. The new modular spool holder uses a bayonet system and can be exchanged for variants for larger spools or a drying box. Technically, the printer remains otherwise identical; the changes are clearly aimed at everyday usability.

Existing devices can be upgraded free of charge by printing the necessary parts yourself. Alternatively, the manufacturer offers an upgrade kit. In both cases, a firmware update to version 6.4.0 is necessary, as only this version supports automatic ventilation control. Firmware, slicer profiles, and G-codes remain fully compatible between CORE One and CORE One+.

Bondtech’s announced INDX multi-material extension can also be used independently of the Plus upgrade. Since key components such as the spool holder and filament feed are replaced anyway, the system supports both variants equally. The CORE One+ thus demonstrates how a modular 3D printer can be technically upgraded over several years without replacing existing installations.
