Filament Dryer S1 Plus

It's cheap and it does everything you need it to do for pla.

Perfect for storing and drying filament nicely made easy to use

Got this to dry out some older filament and to be ready for printing some nylon. It works, no complaints, old PLA that was brittle and tended to break now prints pretty well. Not every old spool prints as well as brand new, but some dried spools do really print like new. I'm happy with the results. The only thing, is there is no enter button on the front panel. You turn it on, hit the left button, then use the right and left button to set your drying temperature. Then... wait for a minute or so and you can then hit the right button and use the buttons to set the drying time. If you press the right button too soon, it's still in temp set mode and you wander away from value you just got done setting. Wait too long and hit the button, it comes up in temp set mode again, you missed the time window to set the time. Once you get past that oddity and both time and temp are set, you just walk away. No beeps, no confirmations the setting took, no enter button to "set" the value. Sort of weird feeling the need to look in an hour to see it's actually working and warm to the touch. OK if I'm still in the shop, but I'm inclined to dry a roll overnight or while I'm doing things away from the shop building with the 3D printers.

Worked great on drying filament. I’m new to 3D printing. Having problems with feeding through extruder and nozzle. Turned out, moisture was the issue. Printer is working great now. Recommend this product.

I bought this because my filament was getting humid and stringing up horribly. This fixed it, and my prints are looking much better in detail. Extremely easy to use, plug it in, turn it on, set a timer and that's about it!

Works good for wet filament, . No problems

I really shouldve bought this sunlu s1 filament dryer sooner. I've been using it for some ninjatek TPU that has been left out for about a year. It has almost completely eliminated my clogging issues. I feel like I will save alot of money over time with this unit as I always threw away filament that was clogging rather than dry it in my kitchen oven. It also nice that you can print straight from the dryer. The reviews that say it doesn't have a fan or get hot enough worried me but I found they weren't accurate to what I received.

I originally bought this to try and help salvage some old proto-pasta coils I had that had gotten brittle and hard to print with. For some of the standard PLA filaments it helped quite a bit, for the HTPLA filaments, however, this did nothing. I also had some older spools of Hatchbox filament that I hadn’t used in a couple of years. I had some prototyping prints I wanted to run through but didn’t want to crack open a new roll of filament so I stuck one inside here with some dessicant packs stuffed in the middle of the spool and left it running for a few hours and then while I printed with it and, to my surprise, the filament was much softer and pliable and printed as well as I expected fresh PLA to print. The primary reason for the 3 stars is that the unit will not stay on more than a few hours regardless of how many hours you set it to run. I turn it on in the morning, set it to stay on for 10 hours, start a 4 hour print… come back in 2-3 hours and the unit has turned off. I don’t know exactly how long it actually runs, but 2-3 hours seems to be when I’ve found it has shut off. Very disappointing, but I just turn it back on and come back a couple hours later to check it again. I went ahead and did the kickstarter for the S2 version they’re coming out with to get 360 degrees of heating surface instead of 180 degrees of surface. I hope they also solve the power off issue with the newer units. Some other reviews have suggested that the unit would need to be airtight in order to work. These people don’t understand thermodynamics… that heat rises and takes moisture with it. Ignore them. When this unit stays on it does exactly what it should do… it heats up the filament and drives out moisture. That said, it doesn’t get hot enough to fully dry filament, which is why I shove a bag or two of fresh dessicant into the center of the spool to help suck the remaining mousture out of the filament and surounding air. This seems to work reliably well. All that said, I wanted to like this enough to get a few more for all my printers, but I’m going to wait for the S2 version from their kickstarter before I consider purchasing more. This one seems buggy. If it’d just stay on like its supposed to, I’d give it 5 stars and already have several more. UPDATE: I returned the first unit I bought and got a replacement. The replacement has not had the same issues as the original where it would shut itself off after an hour or two, confirming my suspicion that the thermistor was bad in the first unit. I have since purchased 4 more of these (couldn’t wait for the S2’s) and none of then have had the early shut-off thermistor issue. They have their fair share of other design flaws, but I’ve designed solutions to those problems (a bowden tube adapter solved all the issues I was having) and, in fact, I’m launching a Kickstarter campaign to share my design with other S1 owners having the same issues.

Ottimo essiccatore per filamenti! Acquistato in promozione qualche mese fa (prime days), utilizzato tantissimo e finora molto soddisfatto dell’acquisto! Consente di impostare temperatura e tempo di funzionamento, manca l’indicazione dell’umidità, ma non ne ho sentito la mancanza. Testato con bobine BambuLab e Sunlu e funziona egregiamente, senza inceppamenti. Silenzioso (si sente solo il ronzio - leggero - della ventola), di sicuro la stampante fa più rumore. Credo sia un buon acquisto se la stampante è posizionata in stanze o locali non proprio asciutti. Io la uso in un locale tecnico e ho dovuto mettere anche un deumidificatore. Prima di stampare accendo entrambi per una mezz’ora e la qualità delle stampe sembra sensibilmente migliorata!

Me ha funcionado bien y con buenos resultados. La calidad del producto no es la mejor, pero tampoco es una chafada, cumple bien, funciona bien y no desepciona. No es nada mala compra.

Very compact filament dryer. So far I have used it for ePLA and TPU spools while printing. Nice and lightweight so it sits on the top of the printer currently on a small custom printed plate (though it will be moved to a shelf soon). Recommended for those printers that do not have an AMS type changer system and want a good way to keep their filaments in good condition while they are printing.

==ENGLISH VERSION BELOW== Diese Filament-Trocknerbox ist wirklich großartig. Sie ist leise, kompakt und macht genau das, was sie soll. Besonders praktisch finde ich den Timer, mit dem sich die Box nach einer bestimmten Zeit automatisch abschaltet. Das ist extrem hilfreich, wenn man den 3D-Drucker aus der Ferne über die Cloud starten möchte. Ich kann das Filament vorher mit dem Timer vorheizen und ein paar Stunden später einfach den Druck starten, ohne mir Sorgen machen zu müssen, dass das Filament zu lange getrocknet wird. Ein weiteres tolles Feature ist die Anzeige der relativen Luftfeuchtigkeit (%RH) im Inneren der Box. So kann man die Luftfeuchtigkeit im Raum mit der im Gehäuse vergleichen, was sehr wichtig ist, um sicherzustellen, dass das Filament richtig getrocknet und bereit zum Drucken ist. Natürlich lässt sich auch die Temperatur je nach Filamentart einstellen, was die Nutzung sehr flexibel und einsteigerfreundlich macht. Zusätzlich hat die Box eine kleine Öffnung, durch die das Filament direkt in den Drucker geführt werden kann, ähnlich wie bei einem integrierten Halter. Für diesen Preis ist das Gerät wirklich jeden Cent wert. Ich kann es nur weiterempfehlen. --------------------------- ENGLISH VERSION: This filament dryer is amazing. It’s quiet, sleek, and works exactly as it should. I love that you can set a timer so it turns off automatically. That’s super useful if your 3D printer is connected to the cloud. I just preheat the filament with the timer, and a few hours later I can start the print remotely without worrying about over-drying. One of the best features is the ability to read the relative humidity (%RH) inside the dryer. This lets you compare the room humidity to the internal environment, which is super important when you want to make sure the filament is properly dried and ready for high-quality prints. You can also adjust the temperature depending on the type of filament you’re using, which makes it really flexible and beginner-friendly. It also has a small opening that lets the filament feed directly into the printer, working like a built-in holder. For this price, it’s absolutely worth it. I can’t recommend it enough.

expédition rapide, facile d'utilisation, je recommande.
