Ensuring that filament remains dry throughout the 3D printing process is essential for achieving high-quality prints. Excessive humidity can cause filament to absorb moisture from the air, leading to issues such as poor layer adhesion, stringing, and an overall decline in print quality. Recognizing this critical need early on, SUNLU became the first brand to introduce filament dryer to the market, establishing its leadership in the field of 3D printing filament dry boxes. This innovative move set the standard for filament care and was warmly embraced by the 3D printing community.
Over the years, SUNLU has released several generations of filament dryers, each thoughtfully designed and continuously improved based on user feedback and specific needs. These dryers have been optimized not only for enhanced drying efficiency and effectiveness, but also to improve the overall user experience. From the first to the latest fourth-generation dryer, SUNLU has consistently prioritized delivering high-quality products tailored to the diverse needs of its users.
Here are the 3 Filament Dryers available on the market.
