Review: Great Filament Dryer (with some caveats) - Overall, this is a great filament dryer with a few areas that could be improved. I'm able to use 4 year old PLA filament that's been exposed to extreme humidity as if it were brand new! Print quality is excellent with little-to-no stringing on filament that previously showed many flaws and stringing during printing. Very satisfied with the overall functionality and capabilities of this unit. I'll continue to use the S2 for drying out and printing old filament, however, there are a few shortcomings I hope are addressed in a future design revision: The lack of an exhaust fan or vents means humidity just builds up in the S2 during the drying process, so the cover needs to be opened a couple times while pre-drying very 'wet' filament to clear out the humid air. Once the filament has been pre-dried, the S2 can be run enclosed without venting...still, it would be great if Sunlu had integrated an exhaust fan. This can be mitigated to some extent by placing silica in the center of your spool, which will adsorb humidity released from the filament during the drying process. The single filament port is limiting as far as how the S2 can be placed. Other filament dryers have multiple ports where the filament can be fed out from (it angles upward, which isn't optimal for filament spools placed above a printer, but works with a long enough PTFE tube run). It would also be nice if they had integrated a PTFE tube w/ fitting, although the stock port does allow a 4mm 'bowden' PTFE tube to fit snugly, so is acceptable for a full dryer-to-extruder reverse bowden setup. Finally, the included power supply has a painfully short cable length....maybe 3-4 feet. I have to use an extension cable to allow it to be placed on top of a double stacked LACK enclosure and connected to a standard height power outlet. Pros: nice aesthetic design & great functional touch screen controls. Highly functional drying of old 'wet' filament. Full-spool heating elements. Silent operation. Easy spool loading and smooth spool rolling action. Cons: very short power cord, only one filament port, no exhaust fan. Angle of filament port may not be optimal for all setups, especially if the dryer is placed on top of a printer enclosure Overall very satisfied with my purchase, but do hope Sunlu continues to improve on their design in the future.
Review: Unobtrusive, effective dryer - The dryer does what it is supposed to do: warm a spool of 3D printer filament at a set temperature to dry it out. The display panel makes it easy to set the temperature and timer, once you figure out the slightly obtuse interface. During heating, the outside of the dryer gets warm but not hot and the sound of the fan is below normal conversation level. The only real quibble I have is that the small footprint of the four legs makes the dryer a little more "tippy" than I would like.

## Features

- ①【SUNLU Filament Dryer S2】As a leading 3D printing manufacturer, we've invested years of research to develop a product that significantly enhances 3D printing results. Our filament dryer is the great solution, improving the printing effect and optimizing the printing process.
- ②【Importance of 3D Filament Dryer】Filaments will absorb moisture from the air, especially if they're old or stored in a humid place. Damp filament will cause many printing issues, but a filament dryer can remove the moisture and help reduse these problems.
- ③【Keep Filament Dry During Printing】SUNLU Filament Dryer can be used as a filament spool holder (storage dehydrator), and can dry filament during printing, thereby improving print quality. This feature is especially important for those who have their 3D printers in humid locations such as basements.
- ④【Revive Damp 3D printer Filament】Moisture can be a real problem for 3D printer filament, especially if it has been stored for a while. SUNLU Filament Dryer is specifically designed to remove excess moisture and revive old filament, saving you time and money by avoiding the need to replace damp filament.
- ⑤【Fast Heating and Even Drying】SUNLU filament dryer heats up quickly to the preset temperature, while the built-in spindle ensures that the filament spins continuously for even drying. Additionally, users can customize the drying time (0-99 hours) and temperature (35-70 ℃) to suit their specific needs.
- ⑥【Very Simple yet Very Effective】The SUNLU filament dryer is user-friendly and straightforward. Equipped with a large touch screen, users can easily set different dry temperatures and times for different types of filaments with just a tap. This easy-to-use feature ensures that users can quickly dry their filaments and achieve superior printing results.
- ⑦【High Compatibility and Capacity】The SUNLU filament dryer S2 is highly versatile, with a large capacity of 265x274x118mm, making it compatible with filaments of 1.75mm, 2.85mm, and 3.00mm. Additionally, the dryer is designed with a translucent lid that enables users to check on the filament without having to open the lid.

### ⭐⭐⭐⭐ Works Well for Drying and Dispensing Filament
*by B***L on December 31, 2025*

This filament dryer consists of a plastic enclosure, hinged at the left side, with heating elements in the top and bottom. There is a fan in it to circulate the warm air. The display / control panel lets you select presets for the type of material you're drying, but you can change the temperature setting and the drying time. Current temperature, set temperature, relative humidity, and drying time remaining are all displayed. There are green LEDs, for effect, to indicate it's running, but they can be turned off. The display has a backlight that comes on when you touch the controls, but goes out after a few minutes of not being used. There are rollers in the bottom to support a filament spool. This allows filament to be fed through one of the small holes in the top, so you can feed filament directly to your printer while you're drying it. I found this feature very useful. The dryer seems to do a good job of removing moisture from my filament, but based on the high humidity reading on the display, it seems to trap the moisture inside the dryer. I just printed an adjustable spacer to hold the lid ajar a few millimeters. Overall, I'm very happy with the sale price I paid, the performance and the convenience of this unit. I can hear the fan running in the next room, if I listen for it. But it's not loud enough to be annoying.
