【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

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.

This is the 3rd filament dryer Ive used and my favorite so far. Ive come to prefer the side load, over the more common top load. The top load dryers usually have a flimsy lid and can be a pain to close correctly. The side door on the EIBOS dryer is thick and easy to put in place. Using the dryer is easy, just plug it in, turn the dial to the desired setting and flip the switch on the rear of the dryer. Theres a small red LED that illuminates through the bottom rear of the side panel when the dryer is on, but you can hear the circulation fan also. The fan is pretty quiet and doesnt have an annoying pitch. While running the outside of the dryer does get warm, but gets hot on the front. My pics show the front of the dryer after running it at the high end of the PLA setting for about 2 hours. The bottom of the dryer got warm, but not nearly as much as the front. I lost the pics of the filament temp measurements, but it was pretty consistent and fell within the desired range for PLA. The humidity monitor is, like most filament dryers Ive seen, powered by a battery. I didnt see a switch to turn it off, so its always on. Having it hardwired, or at least having an on/off switch, would be nice. If I had to get picky, a digital temp display might be nice too at this price point. Although the dial has worked fine and I havent found myself wishing for a temp display. Overall Im really liking the EIBOS Easydry filament dryer and have been going for it over the other two I have.

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.

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.

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?

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.

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.

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.

Been through a number of dryers and this is the best one. Just a simple dial to control the thermostat, a well built enclosure, and a heating coil that is intelligently placed. What more could you want.

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.
