The Bambu Lab H2D, expected to be a flagship 3D printer, is set for official release on March 25, 2025. According to leaked information from reddit, Bambu H2D will feature dual-nozzle capabilities, multi-color printing, and laser engraving, making it a highly anticipated addition to the market. However, one of its most Noteworthy aspects lies in filament drying—the Bambu AMS 2 Pro and AMS HT will reportedly integrate filament spin drying, a feature designed to enhance reliability for users working with moisture-sensitive materials.
Filament Drying: A Crucial Factor in 3D Printing
Proper filament drying is essential for 3D printer filament like nylon, ABS, and polycarbonate, which absorb moisture from the air. If not dried correctly, these filaments can suffer from warping, blistering, and reduced mechanical strength, leading to print defects. By incorporating filament drying into the AMS 2 Pro and AMS HT, Bambu Lab aims to optimize print quality and streamline workflow, ensuring that filaments remain in peak condition both during storage and printing.

The Role of Spin Drying Technology
One key aspect of Bambu Lab’s drying system is the spin function, which provides several advantages over traditional drying methods. First, it ensures even heating by continuously rotating the filament spool, preventing localized drying issues. Second, rotation accelerates moisture evaporation, allowing filaments to dry more efficiently. Third, compared to conventional bulky drying boxes, spin filament dryers tend to have a more compact design, making them space-saving and adaptable to different work environments.
EIBOS: The Original Rotational Drying Innovator
While Bambu Lab’s introduction of spin drying is a notable development, it is not the first company to bring this concept to market. In October 2023, EIBOS launched Polyphemus, the world’s first filament dryer with rotary heating functionality, as confirmed by ALL3D. Featuring a patented 360° automatic rotation mechanism, powered by a gear motor, Polyphemus ensures consistent heating throughout the drying chamber. Unlike traditional dryers, which may have temperature fluctuations, Polyphemus maintains a temperature difference of just 1°C, setting a high standard for filament drying technology.
Last Words
With the Bambu Lab H2D and AMS 2 Pro/HT, a new player has entered the filament drying game, bringing integrated spin drying to its growing ecosystem. This feature is expected to improve print quality and workflow efficiency, particularly for advanced users handling moisture-sensitive materials. However, the pioneering work of EIBOS‘s Polyphemus should not be overlooked, as it laid the foundation for rotary filament drying with its patented 360° surround heating system. As 3D printing technology evolves, competition in filament management solutions is heating up, promising even more innovations in the future.
