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

This works great right out of the box. I have my TPU sitting at 19% humidity in Florida summer, the quality of prints instantly improved. For PLA or even wood, you can print right away without any problems but with TPU, it's best to let it sit for a few hours or until the humidity reaches 22%. you can print a tray that will basically attach the device to the side of the printer. Make sure to get some PTE tube to run from the dryer to the printer so it doesn't pick up any moisture on the way to the hotted. Great purchase and I may get another to add to it soon.

Works really well. Drys my filament. Great quality and easy to use

I really like this dryer. It does dry well, reaches temperature fast, and my unit does get down 12% humidity when drying. I don't feel like I need to vent it every hour to get dry filament. I find the touch screen very easy to use. You don't need to punch a single button 15 times just to get it started. If I am drying petg and that is what I dried last, the setting remains, and I can just put my filament in and let it go. I do find the LED distracting, but it can be easily turned off. As with all dryers, this does make a high pitch whine. Not as bad as the S1 version or the creality dryer which I bought and returned because it was too noisy. (I can hear the creality from another room.) The hole for drying while printing seems a little rough and a more secure and capped version would have been nice. There are plenty of mod videos on youtube if interested.

This is the perfect invention for 3D printing. It is like the only product like this on the market. It allows you to condition your filament WHILE printing! It has a cool LED light circle, it's easy to use, and it can keep running for many hours (24+). I use this all the time. I even 3D printed a stand to hold it at the correct height for my Flsun V400 3D printer. Fantastic price for the value it brings. It saves me time in baking my filament to reduce the moisture. Perfect amazing awesome invention!

Awesome... I've rigged this thing to operate as an inline PETG filament dryer, so the printer, when it pulls filament, it has to pull it out of a dried-out container and through this dryer before it melts it, and so far, it has changed prints from fuzzy and poor looking to smooth and excellent again!

Not really happy with it. Not sure if I am doing something wrong but I set it, it dries, says about 26% humidity, look at it again and filament is reading about 34%. Seems to be a huge fluxuation with in an hour after "it dries". I wanted this to "pre" filament for next project.

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 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.
