【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 is the best filament dryer I’ve used. I’ve tried 5 different ones and this has them all beat. No shutoff timer! I pretty much print 24/7 and not having to turn it on every few hours is a major deal. Having three sides to output the filament means you have lots of options on placement around your printer. The humidity sensor seems accurate. I like that it is batter powered and the unit does not have to be on to see humidity. The temperature can be dialed in (quite literally) for a range of filament types. I would definitely recommend this dryer! Note: in my photo the one on the left is not turned on. The one on the right has been on for about an hour.

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.

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

All filament dryers share a few basic things in common - you set the temperature (and optionally the time,) put your filament in start it drying and let it do its thing, dehydrating the moisture out of the filament. Where EIBOS gets it right and many others that will go unnamed don’t is that the Easdry uses outside air, heats it and then provides vents that the newly humidified air (as a result of the drying process) has a way to escape. A simple dial correlated to the filament to be dried is used to set the temperature and away you go. The Easdry dropped the humidity from 40% ambient to 10% within 2 hours. Also, the Easdry doesn’t power off after 6 or 12 hours, but stays on in the event that a print takes longer and doesn’t quit in the middle of it. It’s been going all day feeding filament to my printer as I have made part after part after part (at this point it’s been going for nearly 12 hours and I still have 3 hours left in the day to print) The humidity monitor is accurate and correlates with a precision temperature & humidity sensor that I placed inside and connected to an Arduino. These humidity gauges bottom out in their range at 10% and realistically 10% humidity at filament drying temperatures is quite dry. Temperature regulation around set point is within 1 degree C. After a printing session the Easdry was turned off overnight and the 16% humidity left in the chamber as a result of moisture being liberated out of the filament, was 16-17% the following morning indicating that there is a good seal around the filament entry door. Perhaps the double walled construction at the door and the rear of the unit serve to provide some insulative capability to the unit. There are two places to put desiccant packets in without interfering with the spool or feeding of the filament. This is a plus and probably helps to maintain humidity level on dried filament between powered-up drying/printing cycles. In fact filament feed is made simpler and more reliable using the included PTFE tubing which I have between one of the filament outlets and a “cat-proof” enclosure to keep curious kitties away from the hot bed and hot end. Leaving the PTFE tubing of the enclosure end, the filament feeds directly into my Titan Aero extruder. No feeding issues, jams or other problems that are typically encountered feeding. I was able to rejuvenate and actually use Hatchbox filament opened 4 years ago, that until I had a dryer was questionable as to whether it would still be usable. The prints before and after drying of this filament showed that dehydrating older filament can be restored - not only were the resulting prints usable, they were very clean. My heavily customized RepRap i3 only has a single extruder, so I don’t have a need for another dryer at this point, but when I do it will certainly be an EIBOS Easdry Series X! This dryer rocks. The price cant be beat. Great job EIBOS! As clarification, this item was purchased by me outright for my own use and I don’t receive anything for writing this review other than the peace of mind that I likely have the best dryer on the market. With a turnkey dryer feeding my turnkey 3d printer how can I go wrong?

As another reviewer mentioned and I didn’t catch until I received it, this is the EIBOS Series X: Easdry filament dryer. I have multiple 3d printers and multiple filament dryers and they range from okay but needs improvements to the (almost) perfect. The EIBOS Easdry falls into the (almost) perfect category! The design is (at least as far as I know) a unique design for filament dryers as most that I have seen are either a half clamshell with a top portion that is hinged and opens to insert the roll of filament or one with a clear boxy top that you lift off and set the roll of filament in on rollers. The EIBOS Easdry has a clear side that locks into the unit, and you remove the side completely and place the roll of filament inside on a center mount that the roll rides on. I want to note that it does take some effort to pull down on the pull cord enough to remove the clear side piece. I do like the design and the look, but the side load design does lead to one issue that is important enough to mention and deduct a star over. Unlike many of the other filament dryers out there that have the filament roll resting on bearings, the EIBOS Easdry has the center of the roll rest on the center post that sticks out in the middle of the dryer. This means that with the weight of the roll resting on the plastic, there is enough friction to keep the roll from moving easily and rolling smoothly. I was planning on using this dryer with my Direct Driver Ender 3 S1 Pro, especially since there are multiple outlets for the filament so I would be able to use the one located at the top and just have it feed through some Capricorn filament tubing to go up and over a filament guide I 3d printed so that it could feed into the direct drive extruder and hotend. I discovered that there was quite a bit and possibly too much friction and tension with the filament (the filament roll I was using is a think cardboard which may have contributed to the issue and a plastic roll may move easier). I will, however, be able to use it with one of my Bowden printers where the path is shorter with much less of a curve. I believe that a simple fix is possible by using two large diameter bearings and a cylinder that the roll would sit on. The rest of the Easdry filament dryer is great, from the dedicated desiccant compartments, very quiet fan (so quiet I didn’t think it was turned on), multiple filament outlets, and easy to use temperature dial. The other filament dryers I have all have some sort of screen (whether a simple LCD type or a detail filed touchscreen) so I wasn’t sure how I was going to feel about one with no screen and a single, simple dial to control the temperature. I have to say that I really like it! It is simple yet very effective and it does exactly what it needs to do, change the temperature based on the type of filament you need to dry. You just load up the filament, close the side door and set the dial to the correct type of filament! Even with the issue of the roll sitting on top of a plastic surface instead of some type of bearing to allow it to roll easier, it is a great filament dryer. It looks good, dries the filament extremely well and is easy and simple to use. I can and do recommend the EIBOS Easdry filament dryer!

The EasDry I received was obviously used. Seriously obviously. It was missing the protection on the clear pane. It was missing the silicon loop that prevents the spool from sliding. I probably spent 30 minutes looking for the silicon loop thinking it was buried in the box. Starting the exchange process. Will update after I receive a replacement.

Every filament spool Ive ever used has center holes that are far smaller than the 2 (50mm) hub on this box. I have a lot of spools for various 3-D printers, and I measured 17mm, 31mm, and 39mm center holes, so this box cannot be used with any of them. Other than that, it seems well made and more solid than I expected.

Had it about 3 months by now and it is by far the best filament dryer I have used. Feels tough, has been dropped accidentally and it is still working just fine. It has an intuitive cover mechanism for swapping the filament that is pretty easy to use. Has holes on every side except the bottom (wish it had one there) Holes mean you can run filament any direction from this machine - comes in handy for tighter shop setups or if it is right behind the printer Would higher recommend this filament dryer

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.

It does what it claims and is very simple to use, I had nearly a full 1kg spool of pla filament that was about a year old and was brittle. This device made it totally usable.
