Just like instant noodles go hand in hand with sausages, buying a 3D printer nowadays often means picking up a filament dryer as well. After all, no one wants to deal with stringing, clogs, poor adhesion, or layer shifting during a print—issues that often stem from damp filament rather than printer malfunctions.
If you’re on a tight budget, a DIY dryer box costing just a few dozen yuan might suffice for users who print infrequently. But for those seeking more stable and efficient drying results, investing a few hundred yuan in a dedicated 3D printing dryer offers better value for money.
Today, we’re introducing eSUN’s latest filament dryer—the eBOX Pro, designed specifically for 3D printing. It makes filament drying and management easy, ensuring high-quality prints with minimal fuss.
As an upgrade to the previous eBOX Lite, the eBOX Pro features a more refined design. The silver-gray body is more modern and tech-savvy than traditional black-and-white designs. The side is marked with a bold white eSUN logo, giving it strong visual identity and brand recognition.
The front is equipped with a responsive touchscreen color LCD, a major improvement over the monochrome screen on the previous version. The display is angled for optimal viewing and ease of use, making operation more intuitive and comfortable. If ergonomics matter in filament dryers, the eBOX Pro is a prime example.
Unlike some dryers that require assembly, the eBOX Pro has an all-in-one design—just plug it in and it’s ready to go. While a user manual is included, the straightforward functions mean almost no learning curve is required.
The touchscreen supports colorful graphical icons and provides satisfying tactile feedback with clear button sounds, enhancing the modern, user-friendly experience. The top of the screen shows the real-time internal temperature and humidity; the middle displays the set temperature, material type, and drying time; the bottom houses the control buttons.
With a tap on the lower-right power button, the device starts up automatically, running the default PLA drying program (50°C for 5 hours). In fact, the eBOX Pro supports up to 70°C and 99 hours of drying time. It’s compatible not only with PLA and PETG but also with engineering filaments like PA, PA-CF, PC, and TPU. Just select the material type, and the system intelligently recommends suitable drying settings.
Notably, the eBOX Pro uses a 360° surround PI heating element paired with top and bottom metal plates for efficient heat conduction, providing even, efficient heating while reducing energy consumption. A built-in turbofan further enhances drying performance and stability.
That wraps up our review of the eSUN eBOX Pro 3D printing filament dryer. It offers excellent compatibility, supporting different 3D printer brands and various filament diameters. If you’re looking for a dryer with great aesthetics, comprehensive features, and reliable performance, the eBOX Pro is definitely worth considering.
If we had to nitpick, it would be the slight noise it generates during operation—but it’s still much quieter than a 3D printer and unlikely to cause any disturbance. Additionally, during initial use, we experienced a momentary issue where the device restarted after being powered off. At the time, it seemed like a bug, but it hasn’t reoccurred since, and the unit has worked normally thereafter.
