SUNLU Official Filament Dryer S1 PLUS with Fan, Moisture-Free Filament Dryer Box for 3D Printer Filament, Easy to Use and Portable FilaDryer, PLA PETG ABS Nylon TPU 3D Filament Dryer SUNLU S1, (Black)

This is great, works well, has 2 holes where you can feed the filament straight into the printer, I keep it on while printing in PETG. Print quality and bed adhesion has definitely improved. Extremely easy to use.

First class item and excellent value for money, does exactly what I need and easily set up.

I've been using this filament dryer since I got my 3D printer, so I can't really compare print quality with and without it. That said, it appears to be doing what it's supposed to do. The humidity reading drops quite significantly over time, which suggests it's removing moisture from the filament effectively. It's straightforward to use and fits neatly alongside my printer. I've had no issues running filament directly from it while printing. My only real complaint is the noise. Every now and then it starts making a fairly loud noise that doesn't sound particularly healthy. It doesn't happen all the time, and most of the time it's quiet enough, so I'm not sure if I've got a slightly faulty unit or if it's normal behaviour. Overall, it seems to do the job well, but I knocked a star off because of the occasional noise.

Works for my PETG filament. Nice and easy to setup and control. Keeps the moisture away from my filament so I get nicer prints than I did previously.

I don't often write reviews of an Item I have purchased on Amazon but this Sunlu Filament dryer deserves a shout out it's truly an amazing product, my 3D prints are all transformed especially TPU and PETG filaments and cheaper generic filament print the same as Bambu labs own brand, you won't be disappointed I guarantee.

I've had this for an hour or so, but it seems to be doing it's job pretty well. Extremely quiet, compared to my food dehumidifier it's infinitely quieter so it can live in pretty much any room. It looks well designed and came with a UK power supply (there was one review that said it didn't which I thought was odd). One thing I wanted to add was that it includes a humidity readout. Nowhere in the advert or the instructions does it mention humidity, but given the objective is to get the filament down to a certain humidity it makes sense. It's currently showing 18% on PETG after an hour, but I'll leave it for a decent time to make sure it gets low enough to use.

It's a great product

Works well but doesn't last Had for under a year before the fan bearing failed causing to be to be extremely noisy. Other than that it does work well enough to slowly dry out filament, and being able to run filament straight from the dryer to the printer is a nice option

Although I have been 3D printing for over 12 years, I never found much use for a dryer until recently when I bought some more exotic filament. I have used this unit a few times and found it very effective and fairly easy to use (if you read the instructions). You can set time and temperature and monitor the humidity in the camber with the digital display. The unit is extremely quiet and it has an option to feed the filament directly to your printer. Great unit and you can't beat the value with the price point. A recommend for anyone who needs a basic filament dryer at a great price.

Está horrible el carrete no gira bien dentro de la caja, arruinó dos impresiónes y la temperatura dice 55 grados pero no es real

Lo utilizzo regolarmente con il PLA e la differenza si nota, soprattutto con bobine rimaste aperte per qualche settimana. Dopo qualche ora nell’essiccatore la stampa è più uniforme, con meno fili e una migliore qualità superficiale. È semplice da usare, abbastanza silenzioso e il display rende immediato controllare temperatura e tempo. Per il prezzo lo considero un acquisto molto valido per chi stampa in 3D con continuità.

Ich habe mir diesen Filamenttrockner erst vor kurzem gekauft, obwohl inzwischen bereits die S2-Version des Geräts erhältlich ist. Trotzdem habe ich mich bewusst für die erste Version entschieden – und diese Entscheidung hat sich für mich als absolut richtig erwiesen. Getestet habe ich den Trockner mit einem PETG-Filament, das seit über drei Viertel Jahr offen herumlag. Beim Drucken hatte dieses Filament zuvor ständig Probleme verursacht: sichtbare Bubbles im Druckbild und deutliches Knistern aus der Düse, typisch für feuchtes Filament. Ich habe das Filament für sechs Stunden bei 50 °C in der Box trocknen lassen und anschließend direkt aus dem Trockner heraus gedruckt. Das Ergebnis war beeindruckend: keine Blasen mehr, kein Knistern, saubere Druckoberflächen – das Filament ließ sich wieder verarbeiten wie im Neuzustand. Genau das, was man von einem Filamenttrockner erwartet. Meiner Meinung nach ist der Umstieg auf die S2-Version nicht zwingend notwendig. Die erste Version erfüllt ihren Zweck vollkommen und liefert sehr gute Ergebnisse. Gerade in Relation zum Preis ist das Gerät daher klar empfehlenswert.

Niet het eerste waar je aan denkt, een PLA filament droger. Maar PLA is een lastig product, bij een wat hogere luchtvochtigheid trekt het spul water aan. Daardoor krijg je rare printeffecten, gespetter door stoomvorming in je hotend en slecht hechtende lagen. Dit ding droogt je filament en je houdt daardoor vaak onbegrepen problemen op afstand.
