This review from Max Funkner(posted in 3DWithUs) demonstrates a methodical approach to evaluating the SUNLU FilaDryer SP2, presenting both technical specifications and practical usage scenarios. The reviewer establishes credibility by positioning the evaluation within the broader context of filament management workflows and comparing the SP2 against other products in SUNLU's lineup.
This review evaluates the SUNLU FilaDryer SP2, a modular filament drying and storage system designed for 3D printing applications. The device features an airtight design capable of accommodating two 1kg spools or single larger spools up to 3kg, with operating temperatures ranging from 35°C to 70°C.
The author employs multiple measurement tools, including infrared thermal imaging and decibel meters, to provide objective data on temperature distribution and noise levels. The practical testing scenarios, such as the extended printing session with the Snapmaker Artisan over several days, offer valuable insights into real-world performance and reliability. The modular design analysis appears well-considered, with the reviewer recognizing both the space-saving benefits of stackable units and the flexibility of accommodating various spool sizes. The technical documentation, including precise temperature measurements and humidity readings, suggests thorough testing protocols. The reviewer's practical tips, such as proper PTFE tube installation and plug management during operation versus storage, add practical value beyond basic product specifications.

The reviewer maintains objectivity by acknowledging both advantages and limitations. While praising the touchscreen interface and transportation convenience, they honestly address the device's relatively large footprint as a potential drawback. The review positions the SP2 within SUNLU's broader product lineup, distinguishing it from the S2 (single spool), S4 (four spools), and E2 (high-temperature engineering materials). Competitive analysis includes references to EIBOS Polyphemus and Polymaker PolyDryer systems.
Testing Results:
The reviewer conducted extensive practical testing, including thermal imaging analysis showing heating elements reaching 80°C while maintaining 70°C at spool level. Noise measurements recorded 59 dB with lid closed versus 73 dB for the S4 model, demonstrating quieter operation due to airtight construction. Extended printing tests over multiple days maintained 20% humidity levels consistently.
Notable Features:
Modular stackable design for space efficiency,
Touchscreen interface with preset programs for common filaments,
Airtight sealing with rubber-lined plugs etc.
Final Assessment:
The reviewer concludes positively, highlighting the device's effectiveness for both drying and long-term storage applications. Primary advantages include modularity, airtight construction, and user-friendly interface, while the main limitation identified is the relatively large physical footprint compared to single-spool alternatives.
