The PrintDry Additional Chamber Kit (ACK) is an expansion accessory for the PrintDry Dryer II 3 Pro filament dryer, designed to increase drying capacity by adding an extra chamber to the existing unit. Users who regularly dry multiple spools simultaneously or work with several different hygroscopic materials in parallel will benefit from the added capacity without needing a second standalone dryer unit.

Moisture-sensitive filaments like Nylon, PVA, TPU, PETG, PC and fiber-filled composites absorb atmospheric moisture quickly, leading to degraded print quality, popping during extrusion and weakened mechanical properties. The ACK allows more material to be kept dry and print-ready at the same time, improving workflow continuity in production environments that rely heavily on moisture-critical filaments.

Key features

• Adds an extra drying chamber to the PrintDry Dryer II 3 Pro, expanding total spool drying capacity without purchasing a separate unit.
• Compatible with the Dryer II 3 Pro system, integrating seamlessly for a single-unit multi-chamber setup.
• Increases capacity for simultaneous drying of moisture-sensitive filaments such as Nylon, PVA, TPU, PETG and composites.
• Reduces the time spools spend outside the dryer and waiting to be conditioned before printing.
• Practical accessory for production environments that regularly print with hygroscopic engineering-grade materials.
