Sovol Filament Dryer Box 2025, SH04 Filament Dry Box for 4 Spools, 3D Printer Filament Dehydrator with Rapid Heating, Filament Storage & Spool Holder Compatible with 1.75mm, 2.85mm & PLA PETG TPU ABS

Hands down this is the best dryer I have used. It is made of metal and feels quite rugged as compared to a flimsy plastic Comgrow that I tried just before this one. Plus this one actually puts out a substantial amount of heat that will actually drive out some moisture found in the filaments. I also enjoy the simplicity of the controls as it is just a nob and I don't have to deal with punching values into a keypad. I can imagine this will last a long long time.

Good setup for my mmu3 to keep my pla dry. Very simple design but heats up quick. Careful with the filament going out of the ptfe at harsh angles as the heat will put kinks in it.

It is as basic as it gets and it works. Plus it looks very retro and if that is something you value then this is a great little unit. I personally like it a lot. The fact that it is 100 percent a slightly reconfigured toaster oven amused me as well.

Might be okay for PLA and maybe TPU but it only gets to 48C after about 2 hrs. It’s basically a toaster oven without a thermostat so you’re stuck at 48 degrees. The good news is that’s the perfect temp to liquify crystallized honey so I’ll be repurposing this item but I would return it otherwise. Just replaced it with the Sunloo and it heats up to 70C in about 15 minutes.

Looks as if I’m the first to review this item. I own two of the Sovol two-spool dryers, they worked as expected until the 12v power supplies went bad on both. I thought direct mains 110v power on the four-spool dryer would eliminate this weakness. My first impression when opening the box was: “Wow, this looks just like a toaster oven”. Looking inside the unit, my suspicions were confirmed: the sides of the interior have the telltale rack-slots found in a toaster oven. This is (as far as I am able to tell) a repurposed toaster oven. I’m not hating on Sovol because of this, in fact I kind-of admire the ingenuity. When I first turned it on, it was loud. I mean like coffee-grinder loud! Some of the parts that showed as needing assembly in the instruction were already put together with a few pieces that seemed to be missing (I later found them loose inside the cabinet.) I started thinking that maybe I had been sent a return. I put a couple of spools of PLA in the dryer and waited for results. The unit came up to temperature quickly and the humidity started dropping immediately. There are no temperature or humidity gauges on the unit. If you wish to monitor this you will need to supply your own. This unit was so loud I became afraid it might be dangerous. I decided to investigate. A Phillips screwdriver is all that is needed to disassemble the unit (I don’t recommend this.) If there was any doubt this was a repurposed toaster oven, it was confirmed opening the unit. You can even see the covered over extra controls usually found in a toaster oven. The fan is inside a secondary enclosure under the cover. The fan blades are made of easily bendable metal and we’re in fact bent out-of-round thus causing the horrible noise. I don’t know if the blades were assembled sloppily or if there had been some shipping trauma. The blades are easily bendable with your fingers. As an experiment, I tried pushing them back to round. Ah, much better. Not perfect, but no more coffee grinder noise. Sovol: please replace this fan with something less prone to failure. Be aware that there is no air outlet in this enclosure. You’ll need to slightly prop open the door to exhaust the moisture.

so far so good at keeping filment dry.

SOVOL I love you. This thing is easy, affordable, and awesome. Thank you!

I bought this the day it was listed and so there was no reviews at all of it, but I liked that this was built of metal and glass, not a bunch of cheap plastic. I have had it a bit over a month and it's been run many times because I always dry my filaments before use and my printer is constantly in use. I was worried about the temperature being too low since it can't be changed (I wish it were possible to make it a bit higher), but it has sufficiently dried out PLA, PETG, and TPU despite sometimes being a lower temp than is recommended. While PLA usually just needs 2-4 hours, some filaments may need to be run more times so that makes it a bit annoying to keep having to restart the timer. I would run TPU for at least 18 hours.Overall this dryer is best suited for someone who mainly runs PLA. It is also a shame that the filament isn't rolled for more even drying. But for the price, I am satisfied with the performance so far, I just didn't want to pay the 200-300 I would need to for a significantly better multi-roll dehydrator. I have not had any issues with unusual fan noise (it's not super quiet either but I 3D print from my garage so I can't hear any of that stuff unless I'm in there - breathing heated plastic all day is not healthy for you so I would suggest not sitting next to this thing anyway). I feel like this will have better longevity in comparison to the cheap all-plastic smaller boxes.
