Prusa CORE One to CORE One+ Upgrade

Upgrade your existing Original Prusa CORE One to the latest CORE One+ with an official upgrade kit featuring automatic top vent control, improved flexible filament loading, a redesigned spool holder and the latest CORE One firmware improvements.

Upgrade Your CORE One

The Prusa CORE One to CORE One+ Upgrade Kit allows owners of the original CORE One to bring their printer up to the CORE One+ specification without replacing the entire machine.

The official upgrade kit contains the required new printed components, fasteners and accessories needed for the hardware changes. Prusa also provides detailed assembly instructions to guide you through the upgrade process.

Automatic Top Vent Control

One of the key improvements introduced with the CORE One+ is automatic control of the top ventilation grille.

The upgraded system automatically opens the vent for lower-temperature materials such as PLA and PETG and closes it for high-temperature materials. This helps maintain a more suitable thermal environment without requiring manual adjustment during printing.

Improved Filament Sensor

The CORE One+ introduces a redesigned side filament sensor assembly. The updated design improves filament handling and makes feeding flexible materials easier.

This is particularly useful when working with flexible filaments such as TPU, where smooth filament guidance can help make loading and feeding more straightforward.

New Bayonet-Style Spool Holder

The upgrade introduces a new spool holder design using a universal puck and bayonet-style connection.

The redesigned holder accommodates a variety of spool sizes and is also ready for use with a direct-feed drybox setup, making it easier to integrate controlled filament storage into your printing workflow.

Latest CORE One Firmware Improvements

The CORE One+ combines the new hardware changes with the firmware improvements developed throughout the lifetime of the original CORE One.

This provides existing CORE One owners with the latest software improvements alongside the updated hardware, helping deliver smoother operation and improved overall printing performance.

What Is Upgraded?

Designed for CORE One Owners

The official upgrade is intended for owners of the original Prusa CORE One. Instead of purchasing a completely new printer, the existing machine can be upgraded with the new CORE One+ hardware.

Prusa also provides the printable upgrade parts free of charge through Printables for users who prefer to produce the components themselves. The official upgrade kit provides the required parts in one package for a more convenient upgrade process.
