Features

  • 1SUNLU Filament Dryer S2As 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.
  • 2Importance of 3D Filament DryerFilaments 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.
  • 3Keep Filament Dry During PrintingSUNLU 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.
  • 4Revive Damp 3D printer FilamentMoisture 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.
  • 5Fast Heating and Even DryingSUNLU 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 C) to suit their specific needs.
  • 6Very Simple yet Very EffectiveThe 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.
  • 7High Compatibility and CapacityThe 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 as hoped
Color: Upgraded S2 White
Works well, decent max heat and intuitive controls. Great way to control humidity in the filaments that are susceptible to moisture. Highly recommend

    • It works as advertised!
Color: Upgraded S2 Black
While researching for a filament dryer, I kept finding reviews of the original SUNLU V2 without the fan and filament holes and they weren't the best reviews. Fortunately, SUNLU apparently has listened to the previous shortcomings and corrected them with what I would say is really V2.1 by adding a fan and two filament ports (which allow moisture to escape). Yes, you hear the fan when running. But a fan is a fan, and they make noise when running. Not every manufacturer is going to spend the extra money to say install a Noctua fan to make it as quiet as possible. I'm not sure the hydrometer sensor is accurate it should be. I never get below 20% humidity, but I don't have anything I can use to properly compare with. I've started to put all my filament through the dryer (even brand new, just taken out of the vacuum bag) and I have noticed an overall improvement in the print quality, and less printing issues since starting this habit. This is with PLA on up to ASA filament. So, I can honestly say this has been a good investment since I am not having to reprint as often as I used to because of "wet" filament and poor print quality. So now I just say that having a filament dryer is a definite "must have" item if you have a 3D printer. And this filament dryer is a very cost-effective item. ... show more

    • Good, not great
Color: Upgraded S2 White
As most say, works and is quiet but would be better with an exhaust fan, a filament hole not at right angle, and wider-spaced feet for stability (all fixable with 3D printed enhancements). The display on the other side would work better for me, but I made do.

    • Great Filament Dryer (with some caveats)
Review Image by Dylan Dylan
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. ... show more

    • Could be improved but it works
Color: Upgraded S2 Black
The dryer is easily tipped over. I had to print a set of foot attachments to stabilize it. The on/off soft button is finicky. Have to press it several times to get it to register. When closing the lid, it is easy to have it ajar because there is lateral play in the hinge and it can sit off to the side a little bit when "closed". Dryer seems to work well and it is compact in size. Build quality is just okay. ... show more

    • Great Filament Dryer.
Review Image by James G James G
I have been 3D printing for almost a year now and consider myself pretty experienced for a hobbyist. I have been printing with this filament dryer almost ten days now and here are my thoughts. Things I love: -The set up took less than 10 minutes. -The controls and settings are super easy to use and change. -The design is super sleek and also supports printing while being used -Quality of prints has improved because of the 360 degrees of heating. -So quiet I almost never hear it while it’s running. -Timer automatically shuts it off when finished. (1 hr-99 hours) -Dries humid rolls really well. I had a filament roll that had absorbed too much humidity and was almost unusable and this helped fix it with minor stringing! Things I hope they improve: -A vent fan would be nice. I occasionally lift the hatch while it’s running to vent any small amount of excess humidity inside. -A longer power cable would be helpful. All in all, I am super satisfied with my purchase and would recommend this to a friend or anyone getting into 3D printing. It has made my prints come out looking better and helped turn almost unusable filament into a usable roll again! If you want to also help reduce your stringing in prints, get one. ... show more
