SUNLU S4 four-spool filament dryer
Dryer for up to four 1 kg spools of 1.75–3 mm filament, useful for multicolour printing.
Category: Filament storage · Assessed from documentation · Updated on October 12, 2026
Why it was selected
Sold by the official SUNLU store on AliExpress. Drying filament and keeping it away from moisture is the documented remedy for wet filament; what matters is that the printer uses 1.75 mm spooled filament.
Limitations
- It does not connect to the printer: compatibility refers to the 1.75 mm filament documented by the printer manufacturer.
- No hands-on test: features as declared by the seller.
- Drying time and temperature depend on the material: follow the filament manufacturer’s guidance.
