SUNLU, a leader in 3D printing material manufacturing known for its range of filaments, has unveiled its next-generation filament drying solution – the FilaDryer E2 – designed specifically to be compatible with a wide range of materials, from PLA to engineering materials. This new product delivers a higher drying temperature of up to 110°C – ensuring optimal conditions for advanced filaments such as Nylon and PC.
Filament drying is the process of removing the excess moisture from 3D printing materials before use. Many filaments, especially engineering-grade ones like Nylon and PC, are hygroscopic – meaning they absorb water from the air. If these filaments aren’t dried, the trapped moisture can vaporize during printing and cause issues like weakened part strength, surface imperfections, and inconsistent extrusion.
The FilaDryer E2 incorporates precise temperature control to maintain stable and uniform heat levels. In an environment of 25°C (±5°C), the system can sustain up to 70°C with ±3°C accuracy. Between 70°C and 110°C, it offers ±5°C accuracy based on measurements taken at four different points – enabling consistent drying for professional-grade results. With internal dimensions of 372mm × 192mm × 186mm, the FilaDryer E2 can accommodate two 1kg spools, one 2kg spool, or even one 3kg spool – giving users the flexibility to dry various spool sizes in one device. A spacious chamber, paired with eight outlet holes and quick connectors, allows multiple filaments to feed out simultaneously while silicone plugs help retain a sealed environment when not in use.
The user-friendly touchscreen, adapted from SUNLU’s S4 series, enables simple operation for tasks such as adjusting temperature and customizing drying or annealing cycles. Even near the upper limit of 110°C, the product’s surface temperature remains below 60°C, which helps ensure safe handling. The FilaDryer E2 supports filament diameters of 1.75mm, 2.85mm, and 3.0mm – accommodating a wide range of consumables, including popular engineering filaments that often demand strict drying and heat-treatment conditions. By integrating UL, CE, FCC, UKCA, and ROHS certifications, SUNLU upholds stringent global safety standards.
In addition to its drying capabilities, the FilaDryer E2 introduces an annealing mode for users seeking to strengthen or stabilize their prints post-processing. This feature presents a valuable tool for professionals who work with filaments that perform best under controlled heat treatment.
By carefully heating the finished print to a specific temperature, annealing helps relieve internal stresses, and enhance mechanical properties – making components more durable and reliable in demanding applications.
The new device also integrates more subtle details, such as ensuring minimal moisture reabsorption and offering quick connections for Teflon tubes, which streamline workflows in multi-printer setups.
With the launch of the FilaDryer E2, SUNLU further reinforces its position in the industry – anticipating and meeting the evolving demands. As the company expands its engineering materials portfolio and refines its products through regular updates, users can expect an ever-improving suite of features.
The FilaDryer E2 is available for preorder on 8 January 2025 at 14:00 UTC.
