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

SUNLU Official Filament Dryer S4 - Priced at £99.99 and boasting a 4.7★ rating, the SUNLU S4 is a powerful upgrade to the S1. It can handle up to four spools simultaneously, making it perfect for those with a diverse filament collection. With its auto humidity control, fast heating, and temperature balance features, it offers a level of convenience that the S1 can't match. However, the higher price tag may deter casual users or hobbyists who only print occasionally. If you're a serious maker working with multiple materials, the S4 is a great investment.

3D Printer Enclosure with LED Light - Available for £39.99 and rated 4.6★, this enclosure offers more than just filament drying; it provides a dustproof environment and maintains constant temperature, which can enhance print quality. While it doesn't actively dry filaments, its protective qualities make it an excellent choice for those working in less-than-ideal conditions. If you’re in a humid space or want to keep your printer clean, this could be a valuable addition, despite not being a dedicated dryer.

Creality Official K2 Ceramic Heating Block Kit - For £32.99 and rated 4.5★, this kit is a bit different. While it's not a drying box, it enhances your 3D printer’s capabilities by upgrading the hotend for better temperature control. If you're looking to improve your printer's performance while keeping filament quality in check, this is a worthy investment. However, it won’t help with moisture management, so you’ll still need a drying solution if humidity is a concern.

Sovol SH01 Filament Dehydrator - At £38.74 with a 4.3★ rating, the Sovol SH01 is a direct competitor to the SUNLU S1. It efficiently keeps filaments dry and is compatible with a range of materials including PLA, PETG, and TPU. The SH01's lower price makes it an attractive option for budget-conscious makers. However, some users have reported that it may take longer to fully dry certain filaments compared to the S1. If you’re looking for a solid, affordable alternative that still gets the job done, this could be the one for you.

SUNLU Official Filament Dryer S1 PLUS with Fan - Priced the same as the original S1 at £29.99 and rated 4.3★, this model includes an additional fan for improved airflow and drying efficiency. If you’re already sold on the SUNLU brand but want something that dries even better, this might be your best bet. The downside is that it may take up slightly more space than the S1. For those who appreciate the SUNLU design and want enhanced performance, the S1 PLUS is a fantastic choice.
