Overview:

Anycubic ACE 2 Pro - 4-Channel Active Filament Dryer and Feeder
The Anycubic ACE 2 Pro (Part Number: DS20BK2A-O) redefines the multi-material printing experience by serving as an intelligent hub designed specifically for FDM makers using Kobra X, S1, and S1 Max printers. This device eliminates the need to pause print jobs for filament maintenance, integrating active drying with continuous feeding in a single, seamless unit. By combining four independent brushless motors with advanced moisture control technology, it ensures that your materials remain fresh and ready, significantly reducing the risk of jams or poor layer adhesion caused by humidity.

Description:

This high-performance filament hub is engineered to keep your 3D printing workflow uninterrupted. It features a robust sealed storage system with real-time environmental monitoring, ensuring filaments stay dry at temperatures up to 65 degrees C while you print. The unit utilizes durable alumina ceramic ports and next-generation buffer mechanisms for faster loading speeds and near-silent operation under 48 dB. With intelligent filament identification and automatic jam detection, the ACE 2 Pro offers a reliable solution for managing four colors simultaneously without manual intervention.

Features:

Streamlined Multi-Material Workflow
Moving away from the frustration of manual filament swaps and separate drying cycles, this hub allows you to maintain peak material quality throughout your entire print. The system actively manages moisture levels using an electromagnetic valve that expels humidity while a silicone sealing ring prevents external air from entering. Real-time data on temperature and conditions is accessible directly through your printer screen or mobile app, giving you full visibility into the state of your materials at all times.

The feeding mechanism has been significantly upgraded to prioritize speed and reliability. Four independent brushless motors drive a next-generation buffer system that doubles loading speeds compared to previous generations. Each motor is rated for over 5,000 hours of operation, ensuring long-term stability across all four channels. The inclusion of an alumina ceramic filament feeding port provides superior abrasion resistance, outlasting standard plastic alternatives and reducing the need for frequent maintenance or part replacements.

Smart Monitoring and Maintenance
Maintaining a jam-free environment is essential for complex prints, and the ACE 2 Pro delivers on this with intelligent safeguards. The system detects filament runout automatically and supports auto-resume functionality to minimize downtime when spools are depleted. If a jam does occur, the quick-release external feeding channel allows for rapid disassembly, enabling you to clear obstructions in seconds rather than minutes. Additionally, the device can auto-detect parameters for Anycubic proprietary filaments when connected, removing the need for manual profile configuration.
