【EIBOS Official】3D Printer Filament Dryer Easdry, 3D Printer Filament Dryer Box with Fan, Adjustable Temperature, Humidity Control & Spool Holder, Compatible with 1.75mm 2.85mm 3.00mm Nylon, PLA, ABS

I didnt know just how much I needed this, I recently got into 3D printing, after I got this I wasnt in a hurry to put my filament in here until my PLA snapped at the printer head. I hadnt used this for a few weeks and just one day while sitting there it snapped. Not sure if this was due to the humidity or what but after it snapped I immediatelu installed my roll. I just wish there was a way to keep this on when the humidity goes above a point then turn back off - Im probably going to install a humidity sensor unit that will control the power, this will allow this to turn on when it grts above a certain point then turn off once low enough. Havent tried printing yet but do feel much better having this in a controlled environment.

This is a super basic, stripped down filament dryer that works as advertised. The side door opens easily with a convenient pull tab latch, though I did have a couple issues getting the door to seat back in correctly, requiring a couple attempts to get it to seal just right. There are three feeder holes (front, top and back) if you want to run filament straight out of the dryer and into your printer and it comes with a 20 length of PTFE tubing. Around the front it has a humidity gauge, which is quite handy for monitoring internal humidity and a temperature dial where you can select the filament type, so you dont have to remember exact temperatures for each type of filament. Inside, there is a cavity in the front bottom where you can stash desiccant to maintain low humidity after drying and there is a tiny red light to indicate its on at the bottom rear of the window. Around back is a power switch and generic, standard two pin power cable, which is nice in case you ever lose your cable. I dried out a new roll of PETG and set the dial right to the middle of the PETG setting. After about an hour I measured it and got a temperature reading of 65°C, which is right on for the 60-70° you want (though their chart here on Amazon recommends 55-60°, which seems just a tiny bit low). I turned it up to the upper end of the PETG range and later measured 71°C, so it seems to be pretty accurate. Now, what I dont like is that it has no timer or auto off. You have to turn it on and then remember to turn it off manually. My other dryer lets me pick how long I want it to run and shuts itself off, so Ive come to expect this pretty basic feature. I suppose I could just plug it into a smart outlet and set it to shut off there, but thats something that should just be built-in at this price. Overall, its a decent dryer and gets the job done, even if it needs a little more attentiveness to shut it off. The build quality seems nice and the dial makes things simple do pick the correct temperature for any given filament.

This dryer made all the difference and I should have bought it a while ago, like when I bought my printer. Ive always been careful keeping my filament in a moisture free environment but after some of my older rolls were constantly having bad prints I decided to give this dryer a try. The results were outstanding! Simply drying the filament a few hours before printing fixed all my adhesion, layer, and stringing issues. The unit is built rather well for the cost. The preset temp knob handy

If you are looking for a filament dryer that actually works, look no further. This one is by far the best I have found. I have tried several other designs and none of them even get close. First off, the temperature control is just an analog potentiometer. This means you can adjust it wherever you want to set it and it will stay there. It is also nicely labeled by filament type and it gets got enough to actually dry stuff (though a smidge hotter would be better for nylon). Additionally, the heater module is AC powered, so it heats up quickly and there is no massive wall transformer block to mess with. There is also no built in timer function: it runs until you shut it off. This is a good thing as timers cause headaches for drybox usage during printing, plus you really dont want it shutting off until you are ready to remove it, because you dont want to leave filament sitting where it can re-absorb moisture as it cools. Probably the biggest and best feature of this dryer, and the reason it actually works so well, is that it is actually vented. Apparently, the people who designed most of the other filament dryers out there do not realize that you need to give the released moisture someplace to go, otherwise it just builds up in the dryer until the air is humid and saturated and then just sits there as it slowly leaks out. This means that filament will not dry out nearly as fast, nor nearly as thoroughly. Having it vented solves this problem. For comparison, look at food dehydrators which operate on the same principle. They are all vented. There is also a pocket in the front of the box where you can place desiccant packs. This does basically nothing to help speed up the drying process, as desiccant packs actually release moisture when heated, rather than absorbing it. However, this is a great place to put your desiccant packs to dry them out and recharge them before you seal them up in a bag with your freshly dried filament. The only real flaw with this design is for use as a drybox during printing. While it can be left on low and has holes for PTFE tubing (and includes some), the central hub that holds the filament really doesnt allow it to turn as easily as it should, especially with cardboard filament reels. With plastic reals it works fairly well and I havent had any real issues with binding before, but with cardboard it gets just a bit too much friction. They really need to make a few changes to the design to put a few roller bearings around the top part of the hub. If they did that then this would be almost perfect. Other minor issues are that the filament hole placement could be a bit better (which is easily solved with a drill) and that the red power LED is so tiny as to basically be a joke (which is really a pretty trivial issue). It would also be nice if they had used a hygrometer module with a temperature reading as well. For reference, the hygrometer used is a standard 48mm x 29mm type, so changing it out for one with a thermometer is quite easy to do. So as a filament dryer, I havent found one better, the price is good, and this is totally worthy of 5 stars. As a drybox, it works pretty well with plastic reels, but as more and more filament is coming on cardboard, it may not work quite as well in some cases. Get one. Your filament will thank you. Recommended!

Dryer quickly heats and dries my filament spools. Has not humidity indicator so I can see how quickly it dries out. Well made and compact. Has hole on top and front so you can run filament thru it during printing

I took my time and reviewed all of the filament dryers extensively. After much research, I settles on the Eibos and I couldnt be any happier. This unit includes a fan (unlike most others), and it does a great job at enclosing the filament completely. They even include about 3 feet of ptfe tubing that youre able to use to sheath your filament as it runs into your printer (unaffected by the elements) - very nice. The fact that there are three exit holes for the filament (top, front, and rear) make it very convenient for positioning so that you can load the filament more easily. There is also an on/off switch at the back, which is super convenient. Stop your research now - buy this unit. I am using it primarily for PLA, but it can be used for so many others!

Bought this unit because it does not have a timer or complicated control interface. Works great and dries my filament for as long as I need to, without needing to restart the unit. Doesnt feel poorly built like some other units on the market, has the best heater and fan design Ive seen, and still has room for desiccant packets if desired.

This is the first side-loading filament dryer I have seen, and overall, it works very well. Two rubber O-rings are provided that stretch over the upper spool support - the idea is that you should place them so that they keep the spool from shifting over toward the door. I did find some of my spools are so wide that I couldnt use the O-rings at all, but the door closed without issue. There are two filament exits, and a supplied PTFE tube inserts into the one youre using to protect the filament until it reaches your extruder. (Oddly, the instruction leaflet never mentions this.) There is no timer, just a temperature control with markings for various filament types, and an on-off switch. A fan exhausts moisture-laden air and a hygrometer reads the internal humidity. Like most of these inexpensive hygrometers, it does not read below 10%. When I used this with a spool of PLA, the reading dropped from the ambient 35% to 10% within an hour or so. I was pleased to see that the humidity stayed low even after I turned off the unit.

I just wish the setting nob had the temp instead of filament type otherwise I love it

Most other filament dryers on the market are rather expensive, somewhere around the $100 range. This filament dryer is a steal for what it is. The packaging was very good when I received the product, and the dryer seems to be good quality. Theres only one control that users need to worry about on the device, and it has an indicator for which material you are attempting to dry. On the side of the unit, there is an LCD screen indicating the humidity inside of the box. This is useful for gauging how well the unit is working, as well as how dry your filament is getting. It doesnt make much noise since theres only one small fan on the back of it. If you want, you can also use the dryer attached to a printer. Theres a grommet on the top with a Bowden tube that allows the filament to feed out directly from the dryer. The dryer works well at drying filament that contains moisture. This helped me out with getting some TPU ready to print on my Ender 3 Pro. Nearly all filaments benefit from being dried out since moisture can be detrimental to print quality. The unit seems to be able to handle most filaments on the market. Id recommend this filament dryer for any printing enthusiast experimenting with different materials.
