I bought this dryer branded as "Jayo" in August 2021 for $21.51 after a bunch of coupons and discounts. It still works fine today and I use it several days a week. There aren't any vents for the hot air to escape or "flow" through so I'm not confident that it's actually drying (I use a food dehydrator for that) but I think it helps prevent filament from absorbing MORE moisture while printing.

Not sure if just inflation since then but don't think it's the best deal at this price.

I was never a believer in filament dryers. Granted, I do live in a state where the humidity is about 20%. I saw them as a big marketing push. While I still think that they have limited purpose, I now have one and I'm pretty sure it's helped in some cases.

I do like the Sunlu dryer with the far. As far as I can tell, it does a good job. It will dry out filaments that need a higher drying temp. A dryer is simply a heater and (optional) fan and timer.

Our filament is stored in our nearly constantly air conditioned house, so wet filament isn't a huge problem for me. I do, though, notice that filament that has been left out for a long time strings a lot more, and it strings less after I dry it in my air fryer (on "warm").

I live in a humid - more like wet - climate, so I got this and put a bucket on top. Works great and dries enough at once for me to fill up my AMS: https://www.walmart.com/ip/858133927

One of the six gallon ones? How long do you leave the filament in there before you start printing with it? I ask because I have multi-year old filament sitting in the basement and will need to re-start my 3D printer soon to print out a few parts. Tnx

Sorry for long delay! I wasn't checking SD and missed the notification.

The size of the bucket will depend on which food dehydrator you wind up with. In all cases, though, be sure to drill holes in the bottom or remove it entirely to ensure proper ventilation. Otherwise, you'll just surround your filament with steamy hot air.

If you go with the Commercial Chef I linked to and want the bucket to sit on top of the base, giving you access to the dial that turns it on/off and controls the temp, you'll need to aim for a bucket with a diameter of about 10 inches (You could also just get a larger bucket that surrounds the whole machine and lift it up as needed, I bet.) I'm using a 2-lb bucket from Lowe's, myself: https://www.lowes.com/pd/United-S...1000421393

There's also a Rubbermaid 6-qt round food storage container that someone made a latches model for, if you want to get fancy: https://www.thingiverse.com/thing:6026825

Alternatively, you can forego the bucket entirely. One way to do this is to remove the insides of the trays with strong scissors/utility knife, leaving the outer frames intact. This will give you space to insert the spools. Of course, you won't be able to use the dehydrator to make stuff like jerky later if you go this route.

I also saw someone using aluminum flashing to surround the outer area like THIS [reddit.com], which is pretty genius. (Other folks have mentioned using saran wrap in a similar way. I tried that the first time and found that it didn't work very well because the fan blows fairly hard.)

And finally, of last week, I transitioned to these PRINTABLE EXTENSIONS [thingiverse.com] to increase the number of spools I can dry at one time. This was before I saw the flashing idea, which seems perhaps easier and cheaper, especially if you don't have good filament on hand. Nevertheless, I'm happy with this solution, since stacking two of the 100 mm versions allows me to dry 5-6 spools. There are a bunch of similar STLs out there for various food dehydrators (although the Commercial Chef - also sold under the brand Westinghouse - seems to have the most available.)

Hope this helps get you started. Definitely PM or reply here if you have more questions or want to bounce ideas off of someone. I promise to pay better attention going forward Wink In the meantime, good luck with the drying process and getting that printer back in action!
