SUNLU Filament Dryer S2, Black | 70℃ Max Temperature,Large screen control,Filament Storage Filament Dryer Box,For TPU PLA PETG ABS

I love this dryer, works so well for drying my nylon filaments and fits on the top of my printer so I can dry and print at the same time. Looks cool, love the value on this as it works well and is so simple to use. Greatly increased the print quality even on my PLA prints.

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 is my honest review; Not sponsored and I purchased this item myself. Pros: easy to use and intuitive lighted touch screen display. Multiple temperature presets with the ability to change the set point as needed. (70c max) Run time can be set up to 48 hours and reset as needed. Auto power off function (pro or con depending on need). Internal hygrometer allows you to keep an eye on how much moisture is in your drier or how much moisture is left or inside while drying. Spool spin freely inside of the drier. (Plastic spools work better than cardboard but both can be used) Filament feed hole to print directly from drier that allows a Bowden tube to be fed from. Heating element on base and lid giving roughly 320-degree heating (rough estimate form looks). Slim design that only take up slightly more space than a standard 1k filament spool. Cons: A bit pricey The unit can easily be tipped over backwards or to the side when changing out filament due to the top hatch having weight from the heating element. (This can be avoided with careful use) It can also be pulled or tipped over by bound filament when feeling from the drier. (These issues can be semi resolved by printing a new base and lid catch found online) If you want to print directly from the unit without the filament being exposed to the elements, you will need to purchase the proper size tubing to fit the drier and if the size differs from the type/size your printer uses, you will have to insert your tubing into their provided cut section which can cause some friction or use 3 segments 92 different sizes) to complete the tubing run. Food for thought/mixed feelings: Due to the compact size of the drier, there is no location to use desiccant or desiccant packets to absorb moisture either trapped in from ambient conditions or from being evaporated from your filament. Some users have designed and printed a lid support that keeps it propped up to allow the moisture to escape. (This could also allow moisture to get in though). At one point I printed desiccant pellet containers that fit in the middle of spools but depending on the spool type, these can wiggle free and cause binding of the spool and ruin a print. I shall be testing different designs to find one that works best. Like mentioned above, the tipping issue can be resolved by either finding or designing a base to give a larger footprint to the drier to keep it from tipping over or make it fixed in place. The size only allows standard 1k spools and possibly 2k spools depending on their width. (I currently only have 1k and 3k spools so I cannot test if 2k spools will fit). From a volume and standard point, this makes sense since most people use 1k spools and allows less air volume to keep the moisture down and give a better heating value. Overall, I am satisfied with my purchase and the drier does what it is supposed to do. I have used it off and on for roughly 3 months and at times for multiple days in a row and it still functions properly. At this price you can build something for less that can accommodate larger or multiple spools (which I've done with moderate success) but having something that does the job right out of the box is quite handy, especially if you do not want to spend the time and effort to do so and do correctly. If this review helped, please thumbs up. Eventually I will make a review for my YT channel as well as the drier mods I have done. These will be located on my YT and IG at Zeons Zone (the other non-project zeon channels are just name stealing wannabes).

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.

Nice and compact works like a charm

Works, dries, gives somewhat quick reading of humidity. Doesn’t autostart based on humidity No seal just plastic to plastic, feed holes will end up getting flared out by abrasive filament.

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.

Bright display, easy to read. I had to look up how to turn it on/off - double tap is a little counter intuitive but once you remember it that is probably a good system so you don't change it by mistake.

フィラメント乾燥に利用中。コンパクトで良いと思います。効果・耐久性は現在確認中。

I have a couple of filament dryers and this one is easily the best, with flexible options and programming for multiple filament types. It even re-energized 8-year-old PLA into perfect printing condition!!! The only drawback is it has one hole to pass the filament through, which makes placing limited (although I don't use it like that, for me it is standalone).

This will topple over and fall if you try to feed filament directly through it. It's 4 legs are not properly secured. I have tried several positions and it has fallen 5+ times already. I finally stopped trying and printed my own feeder.

様々な機種を調べた結果、べた褒めされているこの機種に辿り着きました。 上下のヒーターで加熱するファンレス仕様なので、静かでいいです。 操作もしやすく見た目もスッキリしていて良いのですが、使用している3Dプリンターと相性が悪く、 フィラメントの送りがしくい状態です。 排出穴が乾燥機上部側にしか無いので、下からフィラメントを供給するTINA S2と接続するとフィラメントがS字になり引っかかります。仕方が無いので3Dプリンターよりも低い位置に降ろして使用しています。 下向きにも排出できる穴があれば同じ高さで設置できたのですが... 製品自体はとても良いものです。

付属のユーザーガイドは英文だけでしたが、その裏表紙のQRコードから取扱説明書にアクセスできました。あまり期待していませんでしたが、日本語も用意されていて（一番最後でしたが）よくある妙な翻訳でもなく分かりやすかったです。ドライヤーといっても加熱するだけで、除湿するものではないです。
