SUNLU Filament Dryer Box 2026 New Upgrade S1 Plus, Black | Fan Design, Keeps 1.75 2.85 3.00mm Filament Dry, Compatible with PLA PETG ABS, Filament

The SUNLU Filament Dryer Box has proven to be an effective tool for 3D printing enthusiasts, especially in humid climates where moisture can compromise print quality. Users report significant improvements in their prints after drying filament that had absorbed moisture, leading to better first layers and overall print success. Many found that the device works well with various filament types, including PLA, PETG, and even old spools that were previously Considered unusable. The dryer features a straightforward design with two control buttons allowing users to adjust temperature and time settings. However, several users pointed out the lack of clear instructions, making initial use a bit confusing. It appears that users typically figured out the controls with some trial and error, which detracted from an otherwise positive experience. One of the notable features is the built-in fan, which circulates air efficiently, contributing to the drying process. While some customers appreciated the forward-facing screen design, others noted that, in practice, it can be somewhat inconvenient due to the positioning of their printers. The product's noise level received mixed reviews; it's quieter than some other models, but sensitivity to sound can vary among users. The dual filament slots are a useful addition, though their design has room for improvement, as the plugs can fall out easily. Users also recommend including silica gel packets to enhance moisture absorption further. Overall, the SUNLU Filament Dryer Box is acknowledged for its effectiveness at drying filament, making it a cost-effective solution for preserving print quality. Yet, the product's usability could benefit from clearer instructions and refined design elements. **
