Our Review
The SUNLU 3D Filament Dryer Box S1 is a must-have for any serious 3D printing enthusiast. Priced at £29.99, it’s currently at its all-time low, making it an attractive option for those looking to enhance their 3D printing experience. With a solid rating of 4.4 out of 5 from nearly 3,000 reviews, this dryer box promises to keep your filaments dry and ready for action, which is crucial for achieving high-quality prints.
Key Features in Detail
The SUNLU Dryer Box utilizes a hot-air circulation heating system, ensuring an even temperature distribution inside. You can set the maximum temperature to 55°C and adjust the drying time up to 24 hours via a convenient 2-inch LCD screen. What makes this dryer stand out is its compatibility with 99% of 3D filament spools, including popular diameters of 1.75mm, 2.85mm, and 3.00mm. This versatility means you won’t be limited in your choice of materials.
Noise levels are impressively low, operating at no more than 10db, making it suitable for use in quiet environments or even overnight. The user-friendly design allows you to set the heating filament type with just one click, streamlining the process. The dimensions of the box are 271mm long, 100mm wide, and 237mm high, which means it should fit comfortably on most workbenches.
Performance Assessment
In terms of performance, the dryer box effectively removes moisture from various filament types, which is critical for reducing print failures and improving the overall quality of your 3D prints. Users report that filaments that have been dried in the box exhibit better layer adhesion and fewer stringing issues. However, the effectiveness can vary based on the initial moisture content of the filament before drying.
Build Quality
The build quality of the SUNLU Dryer Box is generally solid. It feels durable, and the heating elements are well-protected. However, some users have reported issues with the temperature settings being slightly off, which might require a bit of fine-tuning. The plastic construction is lightweight, but some may prefer a more robust material for long-term use.
Value for Money
At £29.99, the SUNLU Dryer Box offers excellent value compared to alternatives like the SUNLU S4, which retails for £99.99, or other competitors that do not provide the same level of performance. Given its current price is 8.9% below the average of £32.93, now is a good time to buy, especially if you’ve been struggling with filament moisture issues.
Comparison to Alternatives
When compared to the SUNLU S4, the S1 offers a more budget-friendly option with sufficient features for individual users. While the S4 has advanced features like auto humidity control and can handle four spools, the S1 is ideal for those who only need to dry one spool at a time. Additionally, it’s more compact, making it suitable for smaller workspaces.
