【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.

【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 - $52.99 at time of review. It works and works well. Has a simple humidity monitor on it. Would have been nice if it was backlit. The side panel cover is a nice double walled design to keep in the heat. The heater element itself is a good design to spread the heat throughout the entire case indirectly unlike some heaters out there. There are 3 holes, one on the front, top and back so you can feed your filament out based on how you have the dryer setup next to your printer. They provide a nice long bowden tube which can be moved to any of the holes you desire. And one thing that others lack is stability! Its wider and keeps it from tipping over. You dont need to remember the temp to set it at for each material as it has it labeled on the simple temperature control knob. Definitely prefer that over the digital settings. Really, the only lacking feature on this is a timer to auto shut off. The EIBOS sticker on the side bubbled up on first use when drying PETG. No big deal, but kind of odd they would put a generic sticker right where the heat blows on to.

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.

Ok so I had to test this as I have old rolls from about 2 years sitting out. In the pictures you can see that there are print issues with number one ( old roll ) and in number 2 same old roll but put in the Eibos and humidity was about 39% so as this is PLA I am using you should have it in the unit for 4 hours and it went down to 12% so that brings back the strenght elasticness that the PLA had when made. Also I put them both under my Microscope number1 is ( old Roll ) number 2 is after eibos. I believe that this product can not only save your filament but also money on buying more because you let it sit.

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?

I was trying to print some American made brand of PETG directly from the dryer and had the filament break (twice) while feeding from the box. Too much friction pulling filament out of the box. I played around with the dryer door on vs. door off and I noticed that the spool was dragging when the door was closed. The spool was a tiny bit too wide for the box. Not enough to be obvious. My solution was to add a small felt pad in each of the four plastic corners of the dryer box surrounding the spool so the door is slightly sprung when put back on, but it still closes. The spool now turns with very little friction. I have other spools from a different brand of filament that just dont fit, but they really dont fit at all. It would be nice if this dryer was maybe a 1/2 deeper and then the spool design wont matter.

I evaluated this EIBOS and the eSun dry box. The EIBOS dry box is relatively loud and has no power led visible from the front. However it does have a humidity indicator (which the eSun did not have), but this indicator is on all the time. The biggest problem is the awkward side loading: I would need to take it off my shelf to reload it. This is especially hard with a power cord dangling from the rear. The eSun is top loading which makes it much easier. I cant comment on how well it dries; maybe Ill edit my review after I used it for a few months.

While this dryer does have 3 holes you can pass filament through with an included bodwen tube it quickly becomes more pain than its worth when trying to print and dry at the same time. Place the vent towards your print bed? Get ready for warping! Trying to dry and print off a new role? get ready for the filament to get twisted! Other than trying to print with it feeding out, its AMAZING at drying filament. I had some brittle filament from the factory that would not print and after having it in the dryer for 8-10 hours it came right back to life.

It is simple to use. Open the door, pop in the filament, close the door , turn it on and set the temperature. It uses a fan to circulate outside , heated, air forcefully and evenly throughout the inside. It gets plenty hot to dry the filament. There is a place to tuck in some drying breads, too. There are holes to allow filament to be used while it is in the dryer. I havent used it in this manner, yet. Having filament on a pressboard spool, I felt a good amount of drag, when I tested how it moved. If I want to use it with that fashion of spool, I may have to find a way to reduce the friction for it to turn easily enough. (MAYBE a sheet of PTFE around the spool arm) I havent tried a plastic spool. I suspect it will turn with less friction and be OK. It just makes a fan sound. It isnt too loud and distracting. It, also, has a humidity percentage display ; which is handy. Its been highly reviewed pin YouTube. I agree. This is a very good dryer.

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