【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

An older roll of filament that I have kept breaking on me, multiple places. After running this for a bit, I was able to restore the filament to a useable state and use the remainder of that roll. I would highly recommend this product or something similar if you have a 3D printer and store filament for long periods of time.

This has an easy to use dial to select type of filament you are drying. It comes with extra tubing you can run your filament through to make it pull smoothly. It is vented which allows it to do its job of drying faster. The only minor issue is it drags more than other dryers I have. This puts additional strain on the extruder but probably not much of an issue but optimize your feeding path to keep this as good as you can and watch it. This side loads and you pull down on the strap to release the cover. It was a bit awkward feeding the filament and getting the roll in there but again very minor. Overall I give this 5 stars due to the innovative design. Make it roll easier and it would be optimal. Really everyone should be using a filamanet dryer unless you live where there is no humidity.

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.

First one I received was defective as it did not heat up but return was easy and replacement is working fine. Haven’t tried printing from it yet as it have Bambu AMS that I run most Filament from. Will try next time I need to print you. This dryer seems to be the best value of all that I looked at.

* For printing environments which benefit from side loading spools, you should consider this printer * detachable power cable is a second benefit over the completions * if you prefer a dial potentiometer to adjust the units drying temperature, this is the unit for you! however… * in my printing environment they didn’t work out + these units require the inside of the filament spool to rotate around a fixed plastic ‘axel’. Bottom rollers as commonly used by other solutions at the same price point at not present. * my experience was that several of my spools of brand new PLA would break off causing overnight jobs to stall * the friction tugging against the filament had other negative impacts of printing * nothing against eibos, just this particular design; as I have to work ‘double roll’ solution with front and back rollers beneath each spool and it works very well. * for fem filament dryers I prefer a digital thermostat with lcd readout ) as is standard on other models) that displays bith the user adjusted target temp and the sampled temp.

GREAT PRODUCT. EVEN HEAT AND STURDY. BETTER HEAT DISTRIBUTION THAN SOME OF THE OTHER FILAMENT DRYERS. I HAVE ALMOST EVERY OTHER DRYER AND THIS ONE IS UP THERE.

This is a perfect dryer. Easy to use and clear how to operate to get your desired results. The door latching mechanism is my only complaint. I can see it being the first part to fail but it does seal which why the door is hard to remove.

This filament dryer has proved to be a filament saver. Our 3D printing business requires us to keep 30+ different colors/materials of filament on hand at any time. Some filaments are used less frequently and tend to stop printing efficiently over time because they start to retain moisture. With this filament dryer, I’m able to dry out older filaments so I can use them when I am ready. What I really appreciate about this dryer is that it has a dial to select different materials (PETG, PLA, TPU, etc.) to dry. As an example, I put in a roll of PETG to dry. It started at 46% humidity, and after two hours, it was at 11% humidity. The dryer was easy to operate and understand. I then used the dried filament to reprint a part that had come out stringy and chunky (see photos). I’m very pleased with the dried filament as it yielded a much cleaner print. In this instance, I rescued about $22 of filament that would have otherwise been recycled. After rescuing a couple of kilos of filament, this dryer pays for itself.

Compared to other dryers in this price range, this really blows the competition out of the water in terms of its feature set. The fact that this one has a fan to circulate air, and is vented rather than telling the user to open the lid while drying definitely gives it a leg up right from the start. There are 3 holes on different edges to support adding a PTFE feed tube to feed the filament straight from the dryer to the printer. No timer for operation, so it will stay on until you turn it off, which can be a good or bad thing depending on your use case. The humidity gauge is nice, although it would have been nicer if they had used a unit that displayed both humidity AND temperature, as humidity is always relative to temperature. The temperature knob is also nicely laid out, just giving indicators for filament type rather than listing temperatures and leaving you to figure out what temperature is appropriate. The single biggest problem, though, is the design of the unit will pretty much only support 1kg spools. While this is certainly the most common spool size, due to some recent sales, I have quite a number of 250g spools on hand, and there is no way to get these to fit in the dryer, because the center post is too large for the smaller spools, and because the heater is inside the center post, it cannot be removed to make enough space to get a small spool inside. So, in order to dry one of my small spools, I had to re-spool my filament onto a spare 1kg spool first, which is not exactly ideal. The first filament I dried (Sunlu transparent PLA) actually made me think I was going to have to write a bad review on this dryer, because after 4h of drying, all of that filament deformed, and had actually cracked up into a number of small pieces on the spool itself, and that made me wonder if the dryer got way too hot. So, I then put a thermometer inside and ran it at both PLA and PETG temperatures, and am very happy to say that the temperature knob is spot on to the appropriate temperature ranges. I then tried drying out some Creality Ender series black PLA, and that worked perfectly, so my initial difficulties were from legitimately terrible filament.

Had 2 prints back to back that uses almost an entire roll of PETG. Placed the roll inside, set to PETG, waited for humidity monitor to read around 10% (new roll and didnt take long at all) then started printing. Roll moved ok (Hatchbox Blue PETG) inside the dryer. No hiccups during almost 3 straight days of printing. Prints came out flawlessly too! Very happy with this dryer. Now I just have to figure out how to store my dried filament. Its a good problem to have.
