Anycubic ACE 2 Pro, Kobra X, Kobra S1, S1 Max

Overview of the Anycubic ACE 2 Pro for the Kobra X and Kobra S1 series

The Anycubic ACE 2 Pro is a multicolor feeding and drying module designed to fully unlock the capabilities of the Kobra X, Kobra S1, Kobra S1 Max. It can manage up to four filament spools simultaneously and, when combined with additional ACE 2 Pro units, supports a multicolor workflow with up to sixteen filaments.

Beyond its role as a filament hub, it also integrates an active drying and humidity control system, ensuring optimal material stability and reliable print quality, even during long printing sessions.

Three main advantages of the ACE 2 Pro

Advanced multi-spool management

The ACE 2 Pro can accommodate four filaments in parallel. This allows automatic color switching during printing, offering greater freedom for designing multicolor parts without manual intervention.

High-temperature drying during printing

The module continuously heats up to 65 °C thanks to its enclosed chamber, keeping spools dry even while printing is in progress and reducing the risk of filament degradation.

Active humidity regulation

Thanks to temperature and humidity sensors combined with an electromagnetic valve, the ACE 2 Pro actively removes internal moisture and maintains a stable environment for filament spools, which is essential for moisture-sensitive materials.

Technical and technological advantages of the ACE 2 Pro

Four independent feeding motors

Each filament is powered by a dedicated brushless motor, ensuring smooth feeding while drastically reducing the risks of tangling or feeding inconsistencies during purge and retraction phases.

Improved buffer mechanism

The damping architecture has been optimized: the buffer better absorbs flow variations, limiting micro filament jumps and promoting smoother extrusion, especially useful for fast multicolor printing.

Fast filament switching

Switching from one filament to another is significantly faster than on previous versions: the ACE 2 Pro greatly reduces waiting times, improving efficiency for complex multicolor prints.

Enhanced sealing

A silicone ring ensures the enclosure remains airtight, blocking outside humidity and maintaining a stable internal environment even in changing ambient conditions.

Intelligent feeding assistant

The ACE 2 Pro features an integrated system capable of estimating the remaining filament quantity, automatically triggering refills according to predefined material or color profiles, and recognizing certain filament parameters without manual input.

Review of the Anycubic ACE 2 Pro

As an additional accessory, the ACE 2 Pro stands out as a key component for professional multicolor printing. Its design with multiple independent motors and active drying system ensures excellent filament stability while offering strong scalability: users can start with a single module and expand to a 16-color setup.

For workshops, prototyping studios, and advanced makers, it is a smart investment combining reliability, performance, and flexibility.
