5 Alternatives to the SUNLU Filament Dryer S1 PLUS (Including 2 That Are Better)

SUNLU Official Filament Dryer S4 (£99.99, 4.7★) - If you’re serious about your 3D printing and need a more robust solution, the SUNLU S4 is an excellent upgrade. With the ability to handle up to four spools at once, automatic humidity control, and rapid heating, this dryer is perfect for anyone who frequently switches between different materials like PLA, PETG, and Nylon. However, the price point is significantly higher than the S1 PLUS. Choose the S4 if you're a professional or heavy user who values convenience and efficiency.

3D Printer Enclosure with LED Light (£39.99, 4.6★) - This dustproof tent not only provides a protective cover for your printer but also helps maintain a stable temperature, which can reduce moisture absorption in your filament. While it doesn't actively dry filament like the S1 PLUS, it does a decent job at protecting it during printing sessions. If you also need an enclosure to keep your workspace tidy and controlled, this is a solid choice, especially for those with printers like the Ender 3 series.

SUNLU 3D Filament Dryer Box S1 (£29.99, 4.4★) - If you’re looking for a straightforward, no-frills option, the original S1 model is still a great choice. It’s cheaper than the S1 PLUS and does the job of keeping your filament dry, albeit without the added features of a fan. This is ideal for hobbyists who don’t require advanced functionalities and simply want to ensure their filament is moisture-free.

Sovol SH01 Filament Dehydrator (£38.74, 4.3★) - The Sovol SH01 is a fantastic alternative that offers similar features to the SUNLU dryers. It’s designed to accommodate various filament sizes (1.75mm, 2.85mm) and has a good reputation for effectively keeping your filaments dry. The downside is its slightly higher price and less sleek design compared to the SUNLU options. However, if you want reliable performance without breaking the bank, this is a worthy contender.

3D Printer Enclosure for Bambu Lab A1 Combo (£49.99, 4.6★) - This enclosure is built for larger setups and offers excellent dustproofing and temperature control. While it serves a different primary function than a filament dryer, it does help maintain optimal conditions for your filaments. If your main concern is preserving the quality of your prints in a controlled environment, this enclosure might be the perfect solution. However, it won't actively dry your filament like the SUNLU devices, so consider your specific needs before purchasing.
