Features
- 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 improves the printing effect and optimizes the printing process
- 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 reduce these problems
- 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
- 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
- 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 degrees Celsius) to suit their specific needs
- 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
- 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

I use this thing constantly, and it's a capable and solid device. It does the job, has a good interface which makes setting your temps and timing easy, and has the ability to save presets as well for various filament types. The unit is quiet, doesn't get externally hot at all, and the rolling mechanism for the spools is smooth and doesn't hinder feeding at all. I haven't had any issues with spool fitment or tangling, and sunlu's documentation on the unit was pretty easy to look up as well.

Works great for drying various filaments! I typically use it for PLA and PETG. Reaches the temperatures needed for these and has a built in timer to shut off when necessary. Can also be left on indefinitely until you shut it off. Very easy to use. Over all has helped with my printing quality as it does a great job removing moisture from the filament. This dryer does not reach the higher temps needed for filaments like ABS and Nylon and others. Make sure you check with your filament manufacturers drying recommendations to ensure you are buying a dryer that meets your needs!

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.

Works as it should. Not too technical and not too Analog. Heats and haven’t had any issues with all my pla. Dries filament like advertised.

I bought this with high expectations based on the reviews but based on my experience after having owned this filament dryer for 2 weeks, I should have read the reviews a little closer. I'm using this for both a printer with a Bowden tube and one that is direct drive and this dryer doesn't really work for either. The first thing I noticed which is a major design flaw is that there is no vent or fan on this enclosure to remove the humidified air after the filament has been heated. The best you can do is look for an STL on printables or thingiverse (there are many since this is kind of a huge oversight) for a wedge to insert in the opening to vent the humidified air out. Secondly, there are two PTFE lined holes for filament to exit the enclosure but they are both positioned in a manner that is poorly adapted to allow the filament to flow out of the enclosure easily. No matter how you place the spool or the dryer itself, the filament binds and causes the whole machine to be pulled towards the printer which will interfere with your printer's mechanics while it is actively printing. The rollers at the bottom of the enclosure to allow the filament spool to spin freely are not adequate enough for this device to work reliably while you are printing. At best, this machine is good for drying a roll while not in use prior to storage in a ziplock bag. And again, there are many 3d printable solutions available on thingiverse and printables to address this problem, but for a $70 plastic box with a heating element and a PID, this should not be the case. What I do like about this dryer is the large display with touch screen which is easy to read and navigate for changing settings. The timer also can be extended for long periods of time so no matter how long your print lasts, the dryer will be active. Aesthetically it's pleasing and the LED lights can be turned off so that it won't be bothersome if you have it in a location that that would matter. Unfortunately the major functionality is flawed and requires you to 3d print a solution to make it work properly and that, to me, is unacceptable for a dryer box that costs this much when there are well made solutions that are significantly cheaper. If you are considering buying this dryer, the convenience features of the nice touch screen display do not outweigh the inability for this device to dispense filament on the fly while printing. Look for a different dryer and save yourself some cash. I'll likely return this if they accept it back without a box. Highly disappointed - Sunlu usually does better than this tl;dr Pros: easy to read and navigate display, can set it to remain on for many hours and will not turn off mid print Cons: Poorly designed - no vent or fan to remove humid air from the enclosure while running. Filament will not dispense smoothly from the enclosure due to poor outlet locations in the lid which cause the filament to bind and your extruder will drag the dryer into the printer itself causing major problems and possibly break your 3d printer. There are 3d printed solutions available but you shouldn't have to do that for a $70 dryer. Avoid this product.

I wish I could give this five stars but it has one terrible trait that I cannot see past and have been unable to find a solution for. The item works amazing. It keeps the temperature well, has many options, quiet, easy to use. An item I would like to recommend to others but just can’t. It’s one major flaw is that when filament rolls get low (about 20% left) the roll will get stuck in the dryer, catch, and then ruin prints. I kept thinking it was the filament until I realized it was in fact the dryer doing it. This forces me to manually unwind the filament and check on it every 20 minutes to make sure it hasn’t gotten stuck. I have tried several different brands of filament to include Overture, Sunlu and Prusa and all have caught. If I was still within the time range I would return this item but unfortunately I figured it out too late.
