【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 have many filament dryboxs from the S1 and s2, a Wanhou among others and can say this is one of the best out there, I knew it would be good as ive used there dual one for a few months now and it works great on my IDEX machine. The included fan is what most other boxs are missing. The humidity sensor shows its doing its job. From testing the air coming out from the fan was 67C when put on pc to dry. The only downside I can give the box is the LED showing powered on is hardly visible, otherwise no issues at all. Update: I dried some PCCF that I could not get to dry in my S2, Watched humidity in box go from 43 to 10%, Printed great after

Really impressed with the build quality of this unit. Its very solid feeling and not flimsy. My only other experience with dryers is one made by eSun. The Ebios dryer is a much better unit all around, and at a better price. Has a nice easy to use temperature dial to clearly set to your type of filament and the required temp. Comes with a nice length of bowden tube to plug into the front/top/back ports (whichever is best for your layout needs). It works really well as a filament spool dispenser with very smooth feed (my eSun unit does really poorly with that). It does have a nice sized pocket to place desiccant in to help keep the filament dry and absorb the moisture that is cooked out of the filament. It has a hydrometer to measure the humidity which uses a very common LR44 battery. I was able to save a spool of PETG that had been open for 8+ months. It was printing with zits and bubbles.. after a 2hr run in the dryer it was printing like a fresh new roll. For the cost of a couple of rolls a filament I think the price is right. It has already saved a 25$ roll of filament with its very first use.

This is a very nice unit. It’s made very well and has access to feed the filament on 3 sides. The temp knob takes the guess work out of setting as it is labeled for the various different filaments you can use it with. Great job on this!

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.

This dryer solved so many problems! Ive tried to build my own dry box with axles and adapters for filament to come out, but Ive never been able to get one to work right. Now, I just use this dryer to hold my filament and I dont have to worry about humidity, filament getting caught, or the roll not spinning. I still keep my filament in a well-sealed box with silica gel so it all stays dry, but now when I have to take a roll out I know I can keep it dry and clean, even during days-long prints. And since its enclosed, it keeps all the dust and dog fur off the filament. Overall, this is exactly what I needed and at a good price.

This is a very nice filament dryer, especially considering the price point. The operation is simple: open the side door and place your roll of filament on the central spool holder (making sure to feed your filament out of one of three holes if you are using it as you print) and close the door. Turn the dial knob to the filament type (PLA, PETG, ABS, etc.) and then turn the unit on. It will then circulate warm air to dry your filament until you turn it off, and you can watch the humidity level drop on the built in sensor. The fan runs pretty quietly and the unit does not become overly warm to the touch on the outside (at least on the PLA settings I run at). There is a little area inside where you can place desiccant bags - either to dry them out as well, and/or to help keep the filament dry while the unit is turned off. The side door is clear so you can monitor your filament. When set to the high end of the PLA range, I found the internal temperature was 40-50C and varied somewhat from place to place within the dryer. Are there downsides to this dryer? Well yes. First, there is no operation timer as on some dryers. Which means you cant just set it to run for 4 or 8 hours and have it shut off automatically. Honestly, thats a feature I would have liked since I often like to set rolls to dry overnight. Second, the very convenient dial knob for filament type means you dont know exactly what temperature youre setting it to. So you will have to check the temperature manually if you are unsure or concerned (or just trust the unit to do its thing). Despite a couple of downsides, Im still rating this as 5-stars due to the nice build quality, quiet fan, simple-to-use operation, built in humidity monitoring, and reasonable price.

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!

Its alright. I like a lot about it, including the double-insulated door with the pull-cord release, and the simple one-knob adjustment. But my spools drag the outer perimeter along the inner housing, which causes a lot of resistance while feeding. Maybe I can print some adaptors for difference spool inside diameters to solve this. Off to thingaverse...

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

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.
