Does Sunlu's FilaDryer S1 Filament Drying Unit really work?

Hello, 3D Printing friends! Today we're going to take a look at the Sunlu FilaDryer S1 Filament Drying Unit. 3D printer filaments absorb moisture from the air, and that can cause printing issues. The FilaDryer S1 is supposed to remove moisture from filament. But does it really work? Watch and see!

Interested in the Sunlu FilaDryer S1? Looks like they're taking the Kickstarter route:

I had taken this video down for about a month, because of issues with Sunlu's Kickstarter campaign (I was a backer of it). I did finally receive my Kickstarter unit, about a month after people had been able to buy it on Amazon. I've got a whole other video about the Kickstarter issues, but since I did finally receive my unit (several weeks ago at this point), I'm making this video public again. Apologies if you received a notification about it.

My girlfriend gave this to me as a birthday gift yesterday, and I ran across your video today. She knows nothing about 3D printing, but said she did her homework before choosing this one. I trust her judgment, but I'm still glad to see your review confirming her choice. Thanks for doing this video.

Brilliant review and was what pushed me to get one of these. Mine arrived on 19th Jan 2021 and there seem to be a few updates. The inside insulation is now a single layer of black rather than the foil. It comes with Teflon tubs for the filament holes (1 fitted and 4 spare) and lastly the backlight on the LCD has been improved and it can be easily read.

Boy, does this thing work! I had nearly a full roll of Matterhackers PETG that sat around for like 2-3 years. The print I tried to use was hideous; it was covered in tough seam nodules and cat-whisker like stringing. The hot end made these delecate snap, crackle and pop sounds while printing and kew immediately that moisture was the problem. After 8 hours total drying in 12, still some stringing but vastly better. And after neary 12 total hours of drying in my first 24 hours having this unit, the PETG prints better than brand new!

As for your review video: very thorough and well done!

13:34 RGB backlight? Top of my list would be a built-in humidity sensor/readout! :)

Practical print tests will be better than theory.

Just received the unit you discussed. Thank goodness you put the video up because I got a warning SUNLU's manual was hosted from a sketchy website and I received a warning. I will pre-weigh all my old spools and get a benchmark to work from before and after. Thanks so much.

Awesome explanation, subscribed and liked

The print bed is typically big enough to hold a roll sitting flat. Set the roll on the print bed at end of day, cover with the box it came in (cut out the bottom), set print bed to 55C, wake up and it is ready.

In Australia, power outlets have a switch :) Oh btw, my Sunlu S1 have a bright screen

You are an excellent speaker. I didnt realize how hard it is until I made some of my own videos on a different channel.

TL:DR The unit dries well. It removed 2 cubic centimetres from a TPU roll. It's quiet, small, and looks good. The computer interface is good, but the backlight is dim.

I ordered one today via your affiliate link. Thanks for the great review.

[edwardnewbold]

Terrific review. I just purchased one via your Amazon link. Thanks.

[saltysteel]

Got mine on Amazon for 62 bucks, free shipping. Showed up in 1 day. Seems to be working well so far.
About to try some CF nylon, which is the reason why I bought this dryer.

[JoeSnuffie]

I have one and it works great. Some filaments need a double-dip but it gets the job done.

Hello 3D Printing Friends! I've seen a number of comments about the lack of availability of this product. I think there was a limited production run, and I, along with a few others, received a unit. Sunlu commented (and responded to a few other comments), indicating they're taking this to Kickstarter in mid-July. So it looks like they're building hype for the product, attempting to gauge interest, and hoping for some Kickstarter exposure, similar to what Creality did with the CR6-SE.

I've been very impressed by the unit I received. If Sunlu is able to deliver the same build quality as the product I received, and keep it at the $60 USD price point or lower, they're going to do really well with it.

So if you're interested in the FilaDryer S1, hang in there. I would expect to see the product available on their site again probably around the end of July, if not sooner.

I know this is old, but I had kind of yolo bought this off Amazon without really watching reviews and I can also attest that it definitely works. My buddy gave me some multi-year old filament and it popped a lot and was messy. After drying it for 6 hours it definitely prints better and has no pops while printing.

Hi Bryan,
I hope you’re doing awesomely well. Another great video. I like the variety that you’re putting up now. Good luck can’t wait till you’re at 10, 000.

I bought this model based on this video and started using it 6/7/23. I had no back lighting dimness problem on the menu screen.
