Our Review
The SUNLU Official Filament Dryer S1 PLUS is an essential upgrade for serious 3D printing enthusiasts looking to enhance their print quality and reliability. Priced at £29.99, this unit offers a remarkable 25% off the list price of £39.99, making it an attractive investment, especially as it's currently at its all-time lowest price. With a solid rating of 4.3 out of 5 from nearly 1,000 reviews, the S1 PLUS is gaining popularity, with over 200 units sold last month alone. The dryer is designed to keep your filaments moisture-free, combating one of the most common challenges faced by 3D printers: filament degradation due to humidity.
First Impressions
Upon unboxing the SUNLU S1 PLUS, the first thing that strikes you is its sleek, portable design. Weighing in at a manageable size, it’s easy to move around your workspace, which is a significant advantage for those with limited space. The user-friendly controls are intuitive, allowing you to quickly set the drying time and temperature, making it a breeze to operate right out of the box.
Key Features in Detail
The standout feature of the S1 PLUS is its built-in fan, which ensures even heat distribution, significantly reducing drying time. This is a crucial enhancement over previous models, as moisture absorption can lead to filament brittleness and poor print quality. The dryer is compatible with a wide range of materials, including PLA, PETG, ABS, Nylon, and TPU. It effectively keeps filaments dust-free and moisture-free, ensuring optimal performance when it’s time to print.
Performance Assessment
Users have reported improved print quality, citing better layer adhesion and smoother surfaces. This is particularly noticeable when using hydrophilic materials like Nylon or ABS, which are notorious for absorbing moisture. The efficient heating system also contributes to maintaining the integrity of filament properties, which is vital for achieving consistent print results.
Build Quality
While the overall build quality is impressive, some users have expressed concerns about the durability of the plastic casing, particularly with frequent use. However, the compact design and lightweight nature make it easy to store, which could mitigate some wear and tear over time.
Value for Money
At £29.99, the SUNLU S1 PLUS presents excellent value, especially when compared to other options like the SUNLU S4 Filament Dryer, priced at £99.99 with a higher rating of 4.7. While the S4 offers advanced features like auto humidity control, the S1 PLUS is more than adequate for most casual and semi-professional users. Given its average price of £49.45, purchasing now at this all-time low represents a 39.4% saving.
How It Compares to Alternatives
Compared to competitors like the Creality Official K2, priced at £32.99 and rated 4.5, or 3D printer enclosures priced around £39.99 with similar ratings, the SUNLU S1 PLUS stands out due to its specific focus on filament drying rather than general protection. For those prioritizing print quality through moisture control, the S1 PLUS is a strong contender.
