【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 dries my filament very well and can heat up rather warm for filaments like nylon.

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

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.

Overall it works, but this model doesnt shine a light on their double spool model. I really liked the double spool model and when my 3d printers multiplied (as they tend to do), i got the single model. I like the compact form factor and ease of use. I dont like that it is slower to dry than the double and I think its because of air flow. I also find the ball bearing rollers on the double model work better on both cardboard and plastic spools than the single model. The single model just hangs the spool on a round, non-rotating plastic piece. If I hadnt used their other model I might not even have noticed these things because it does work and I am going to use it, but if your budget can afford the double model, get it instead.

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.

Works well, but the humidity sensor is terribly inaccurate. 5 mins after you put some filament in the screen will read 10% (and thats as low as itll go) even though theres no way its actually at 10%. So I recommend you get buy a wifi or zigbee or zwave humidity sensor and you throw it inside with your filament. On the bottom left hand side of the drying chamber theres a small unused bit of space measuring roughly 30mm x 50mm that you can use to put a custom sensor in. For reference on the different when the dryer reads 10% my sensor is usually reading ~35%. Additionally the fan isnt super loud but it isnt quiet either so you probably wont want to have this on top of your desk if youll be spending a lot of time around it.

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.

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.

I live in a very humid area and noticed I was starting to have issues with my filament finally, so I decided to pick this up. Not a whole lot to say really, it managed to work exactly as intended going from 81% humidity down to 12%. It’s fairly quiet, works well, and has super simple controls.

Finally, a dryer that I dont have to turn back on every 12-24 hours! Great for nylon, gets nice and hot.
