【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

this was a great value for a filament dryer, pretty plug and play no real setup, dropped the humidity to 10% overnight.

Its a nice filament dryer box. I threw in my half used up roll of PETG thats been sitting out for about 2 months and cranked the knob to the indicated level. The fan is somewhat noisy but its not nearly as loud as any 3D printer with a fan or two. The filament prints like it was new, or just about. The humidity inside the box slowly drops as the heat is applied but as soon as the drying function is disabled the humidity goes back up. Not exactly the best place to store filament once its dry, but better than out in the open. Its a better use case for active environments unlike mine where a filament roll sat for two months.

I like this unit. It works really good. I like the fact that there are no electronics, no timers, no auto shutoff BS etc. I have this mounted to my 3d printer enclosure and I can leave it running the whole print, even 48, 100, 200 hours if that is how long the print takes. That is very handy. Many other units have auto shutoff, which sucks. It has only one switch to turn it on and off and a dial to set it to a heating position for PLA, PETG, ABS etc. The dial starts at PLA and moves to higher and higher temps for other plastics. It does have this cheap little humidity sensor on the front. They are not very accurate at all. I checked it with another humidity sensor inside the box. LOL The problem is, the temps are not exact, the dial is like a potentiometer, it free spins instead of clicks to a position. This is nice in one aspect because you can turn it higher or lower. The problem is you have no idea what the temperature is inside the box. It does have several holes for options to pass the filament through and it comes with some bowden tube to run it through. What you have to do is put a thermometer through one of the holes and slowly adjust it to the temp you want and watch for a few minutes to make sure it doesnt climb. With mine for example, the lowest setting for PLA gets up to 60c and stays there with no effort. The higher end of the PLA area is probably about 70c I was surprised with how hot these can get for such a tiny heater. The design is really simple and good. There is tube in the center that the roll goes on. It has no bearings and doesnt need any. The spool just spins freely. What is 100 times better though is I can insert plain old hand rolled filament around the tube and it just works. I do check it and make sure no knots for during print with the hand rolled stuff. But jus being able to do that makes this filament drier 100 times better than the rest in my opinion. This means I can buy cheap filament that is not on spools and use it. This also means this would work with the hand held 3d print pens perfectly. This was an added bonus. I had some cheap non spooled filament that came with the printer and now I can finally use it. LOL More on the design. Inside the tube is a fan blowing over a small PTC heating element. It is so simple it is surprising. The only thing people might object to is the unit pulls air with the fan from the outside, at least that is what it looks like. But from my experience it makes no difference at all. The heat keeps the humidity lower. I printed old cheap PLA, not stored in a dry box etc. on a rainy day when humidity was at least 80% and had no issues with print quality. Some might say the fan is noisy, but those people complain about noise from any fan so oh well. It isnt more noisy than the damn printer that is for sure. LOL It is quieter than the cooling fan on the printers power supply. Sort of a low hum, but very noticeable. To work as well as it does and be so versatile, I could care less what it sounds like. I just hope the fan is a high quality ball bearing fan. If not when it dies, Ill replace it. I ordered this by accident. I had ordered another dryer, it didnt show up. So I cancelled it and looked again and found this one. I am glad I did, this is better than most of the others. This only looks to hold regular sized rolls, not larger rolls. And the rolls fight with about a half inch left on each side, so it is a nice fit. Also behind the humidity sensor, inside the box, there is a nice area to put desiccant, which I do.

This thing is great! Easy-to-use knob to control temp based on filament kind. No unnecessary screens or buttons to be finicky. Simply turn it on and set knob to desired filament. too simple not to love it. Plus, comes with a 12”+ Ptfe tube to guide filament. What you see in the photo is what comes with it. I have mine inserted in the top hole of the dryer and into a filament guide I got off printables that uses a bearing to guide filament. “Filament guide w/ rotating head” I purchased the sunlu, the Sovol dual roll and this dryer and I have to say this one is wonderful! I’ll be returning the others and buying a few more of these.

This is a waste of money and time. It arrived scratched. They toss the power plug inside the unit, and it bangs around during shipping, causing damage. The humidity readout isnt even close. It reads over 40%, in the desert, during a dry spell. There are multiple holes to run filament through, but they are all in dumb locations - the filament has to go around corners before it goes throught the holes. This causes friction, which causes printing problems. The sides of the unit get warm, so if you try to use it while printing, your filament will bend and stretch where it comes out. This will cause printing problems. It doesnt work as storage, because its nowhere close to airtight. So, what does this thing do? It does nothing. It is useless.

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!

Most filament dryers do not have a fan, this one does. Seems built very well.

I will preface that I have yet to be able to use the box for its intended purpose but looking at the features and functionality along with the company its from I have NO doubt it will work great. Look for my 90 day update in 2023.

This is my second filament dryer after my first TwoTrees brand and I can definitely say this one is a heck of a lot quieter than that other one. It also comes with THREE outlet holes to choose from on the front, back or top if you want to print the filament while youre drying it. Very cool idea. Now, it does not have rollers but the plastic is smooth enough that it looks like the filament spools will still rotate. However, I did not test this part so cant say with 100% accuracy that this will be the case. Although, it APPEARS to be. You have the humidity sensor in the front as well as the filament temperature options: PLA, TPU, ABS, PETG, PC and PA. There is no option to set the temp yourself - you just set it to the filament you have in the dryer and it will set it accordingly. It comes with just the dryer, a power cord, a filament tube and instructions. The instructions are VERY basic but thats okay - its pretty obvious what needs to be done here. Just stick your filament roll in, feed it out of one of the three outlet holes (if you want to print while drying), set the filament option, plug it in and then turn it on. To test, I stuck a roll of PLA filament I had sitting in my cabinet and it went from 35% to 16% humidity within 15 minutes. However, you WILL need to monitor this as there is no auto-off and you will have to turn this on manually. A minor disappointment as this should be a basic feature on any filament dryer. And like I said earlier, this thing is so much quieter than my first filament dryer. Its not silent, but the fan is low enough that its not a bother. I have it in the same room I remote work from and it doesnt bother me one bit. Also, I cannot make any claims on durability or longevity yet as I have not had this for very long, but I have no reason to believe it wont last a while. However, if anything changes I will certainly update my review. If youre looking for a solid filament dryer, I can wholeheartedly recommend this one.

I like this dryer. It is compact and super easy to use. It has a fan which is nice. I have been using the Sunlu S1 which works pretty well but does not have a fan. I have multiple printers so it is nice to have multiple dryers. If I have older filament, I run it before I print to dry it out. I run a dryer every time I print now. (either one) I think that a dryer is a good upgrade to print quality. I have better luck with tricky filaments and adhesion since I have been using a dryer. (not a dramatic difference but a difference) This is a little easier to use than the Sunlu but not much. It is a little more compact too. I like that this dryer has a fan. The price is good. It works well and is pretty simple.
