SUNLU Official Filament Dryer S1+ with Fan, Moisture-Free FilaDryer

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.

In my honest opinion Sunlu is one of the best filaments I've used, I've little to no issues with failed prints and the failed prints have been down to me.

One of the cheaper Filament dryers available on Amazon, and for the price, it will do the job. Would be nice if it was a little more sealed, but as such, I am apprehensive about keeping the filament in there after drying/printing is complete... For a little more, I could have bought a better-sealed example more suitable for storing as well as drying, but I ended up buying some sealed containers instead. Aside from that, it seems to dry the filament well and allows direct to print feed without any issues so far. It's a little flimsy, but for someone who's not printing constantly, it'll be fine.

I'm happy with this purchase and have had no issues with it. Overall, I'm pleased with my purchase.

Had some of my filament start really print bad and after googling the symptoms it sounded like the filament had too much moisture. So time to try a filament dryerBeing a cynical (and tight) old fart I don't believe most of Amazons reviews (I have a drawer full of wireless earbuds that back me up on this) so looked around elsewhere. There were some pretty good videos that showed comparisons of dryers only a few expensive ones were really good. One guy recommended getting one of these and putting a fan in it to improve circulation and pop a sachet of silica gel in the middle of the spool to grab the moisture. Ok, that ticked my boxes: cheap and tweaked to perform like something far more expensive.Right, to cut to the chase this has worked on all but one of my filaments. It's made most print a whole lot better, revived one that was what I thought was bin fodder but could not fix one (glow in the dark pla ).It does take a while to cook the filament but it is a lot cheaper that buying new and a lot less fuss that vacuum baggies. You can print a nice little fan mount and silica gel holder on thingiverse and buy buckets the gel on here dirt cheap.

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.

Overall I am disappointed in the SUNLU S1 dryer. Main reason is despite having printed a dessinant holder for it, this unit struggles to get below 35% humidity, and filament never as dry as when using other dryers (printing issues with filament dried in the S1).To top it off, after only 2 months the fan has started to make a loud noise intermittently. The return window closed 3 days ago, so this will be a paperweight.Save yourself the trouble and buy something else. This is the epitome of “buy cheap, pay twice”.

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.

Funkar riktigt bra för att förbättra utskrifterna, varmt och torrt filament direkt in i skrivaren

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

Does the work nicely, noise is almost equal to zero, controls could have been easier but overall happy with purchase.

De Sunlu S1 is een prima droger die gemakkelijk in het gebruik is. gebruik hem nu 2 weken, rollen worden goed gedroogd tot ca 20%
