SUNLU FilaDryer S4 comes with a design size of 458mm*218mm*312mm. It contains up to 4 rolls of 1kg filament. Plus, it is equipped with eight filament holes, and PTFE tubes, which meets the users' demands for drying multiple filaments and for concurrent printing while drying with multiple printers.

SUNLU FilaDryer S4 is equipped with the PTC (Positive Temperature Coefficient) heating element and a triple-fan configuration and therefore it demonstrates enhanced heating efficiency by being able to heat up to 70°C in a shorter amount of time. The PTC heater boasts a heating power of 330W, 6.9 times more powerful than SUNLU FilaDryer S2. The 3 well-positioned fans also ensure even heating and drying.

SUNLU FilaDryer S4 comes with pre-configured temperature settings of commonly used filaments such as PLA, ABS, PETG, as well as TPU, PA and PC. These configurations are based on testing data, providing optimal drying time and temperature. By expanding options while reducing setup complexities, we aim to improve your experience.

With the auto humidity control function, when the humidity in the box reaches the set value (30%-50%) it will automatically start until the humidity drops to 25%, and then stop, to better meet the humidity needs of different types of filaments.

Integrating the PTC heating element and a two-level temperature control safety switch design provides a dual-safeguard system. Moreover, a soft gel layer is applied to the roller to prevent issues caused by prolonged high-temperature exposure, effectively offsetting the risk of minor spool deformation that could rise rotational disruptions. 

SUNLU FilaDryer S4 supports all models of 3D printers connected to use; supporting 4 printers in drying filaments during printing. Compatible with filaments of diameter 1.75mm, 2.85mm, 3.0mm.

This product was advertised as 1,10 of retinol and i was looking for a stronger product than the 0.025 Retin~A that I.m using now. Looking at the ingrdieients there is very little Tretinon which is the active ingredient in RetinA. very disappointed!

An Absolute NEED In My Skincare Routine!!
Pattern Name: 50 count (1 pack of 50 ct), Pattern Name: 50 count (1 pack of 50 ct)
These are an absolute need in my skincare routine! I use them to remove oil-based and water-based cleansers and to remove masks. And I use them to dry my face and then to dry my hands in between products. They are very good quality and very soft. They are also thick and very durable. They have a smoother side and a textured side for very gentle exfoliation. I notice my face is more clear from using these as opposed to my microfiber washcloths. They’re fragrance-free and don’t really have a scent, maybe a very light, practically unnoticeable, bamboo scent. I think it’s a very good deal to get 50 XL disposable face towels for $17. I was using these for months and then didn’t use them for a few months and yeah huge difference in my skin, which is why I bought them again and will continue to. It’s also great not having to wash them lol! I also love the new magnetic lid closure and the new design of the box, you can now have your face towels fully covered and sealed without having to buy a separate box with lid to put them in. Although their prism holographic box is so cute and pretty, and their prism box is $20 cheaper on Amazon!

Great quality face cloths with a soft exfoliating texture to them.
Pattern Name: 50 count (1 pack of 50 ct)
Absolutely love these towels. So nice to have a clean towel every time you wash your face. They are the perfect texture for lightly exfoliating. These are just dry towels so you can use your own face wash with them. They are very durable. I tried ripping one in half once and was unable to. They are quite large and I have found that I can have twice as many by cutting them in half. They are still a great size after cutting them. I can definitely see why they are so highly rated. I definitely wasn't holding my breath with high hopes but after using them I am pleasantly surprised! They are quite reasonably priced especially if you cut them in half and if you subscribe to them for additional savings. Very surprised how much I love them!
