【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 has an easy to use dial to select type of filament you are drying. It comes with extra tubing you can run your filament through to make it pull smoothly. It is vented which allows it to do its job of drying faster. The only minor issue is it drags more than other dryers I have. This puts additional strain on the extruder but probably not much of an issue but optimize your feeding path to keep this as good as you can and watch it. This side loads and you pull down on the strap to release the cover. It was a bit awkward feeding the filament and getting the roll in there but again very minor. Overall I give this 5 stars due to the innovative design. Make it roll easier and it would be optimal. Really everyone should be using a filamanet dryer unless you live where there is no humidity.

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.

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 like this dryer. It is compact and super easy to use. It has a fan which is nice. I have been using the Sunlu S1 which works pretty well but does not have a fan. I have multiple printers so it is nice to have multiple dryers. If I have older filament, I run it before I print to dry it out. I run a dryer every time I print now. (either one) I think that a dryer is a good upgrade to print quality. I have better luck with tricky filaments and adhesion since I have been using a dryer. (not a dramatic difference but a difference) This is a little easier to use than the Sunlu but not much. It is a little more compact too. I like that this dryer has a fan. The price is good. It works well and is pretty simple.

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 product is well designed in almost every respect. I like the multiple hole options for running filament out of it. Slots for dessicant in the corners work well. The temperature control on the front and humidity reading are easy to understand. No auto shut off feature. My one isssue is the filament spool doesnt rotate easily enough inside the box to print from it. Theres too much drag on the filament and it keeps it from feeding correctly.

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.

What can I say, it’s simple to use and it does the job. Only issues I’ve seen is at least one of my rolls of filament doesn’t want to turn. Other than that it gets the job done.

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.

This is great for drying my filament for use, though it does have holes you can use to feed the filament into so you can use it straight to your 3d printer at least for me it can cause issues printing if the filament gets stuck somehow inside the dryer, so this will just be used to dry filament for me.
