Comgrow Filament Dryer, Upgraded Filament Dry Box, Large-Capacity 3D Filament Dehydrator for 2KG Filament, Compatible with 1.75mm, 2.85mm Filament and PLA PETG TPU ABS Material

Very handy. Simple to use. Works well to dry filament to use or store. Also works as a dry box on filament that needs to be dried as it prints like nylon and TPU. I can run a PTFE tube directly from this dryer to the printer.Note that the default temperature for filament is usually about 5 degrees centigrade below the recommended drying temperature, so it needs to be adjusted every time. Easy to do.

Working very well even with almost non stop use.Like others have noted, it could use a open/close vent.I seal it and let the humidity rise to 30% and vent it. This seems go work well.

easy to setup and connect to your printer. Works very well to dry your filament. Really helps with print quality

One of the key reason that a 3D print fails or has a poor printing can be summed up in two words: damp filament. Damp filament breaks easy, prints poorly or erratically. A break can leave you with a broken piece inside the Bowden (feeder) tube, and that can be a real pain to get out. So I bought this dryer. 12 hours overnight and you are ready to print!

As a straight filament dryer, it’s easy to use and effective, printing from the unit with anything that has resistance such as TPU results in repeated failures. The exit of the printing tubes being at an angle and so close to the filament causes the ptfe tubes to have a decent bend in them, increasing resistance while pulling on the filament. I feel a unit that has a flat top feed port would work better as it is less sharp bends of the filament before hitting the extruder.

Nice small and extremely quiet unit. So far it seems to be working. After using it it is a quality unit. I recommend it to.

Worth the money. Need to crack it open a bit to move the humid air out. 👍

I've owned this dry for almost 2 years. I have rarely used it (under 5 times). It's primary function is a paper weight that you can put filament in. The actual drying function has been such a pain that I haven't even bothered using it. The dryer would turn on and within 15 minutes after I put in the settings (temp+time) the unit would just shut off. Today I dug the box out of retirement to try and dry some pa6-gf. The unit heated up and 10 minutes later i find the unit off. Now the unit wont turn on and throws a E1 error. I took the unit apart to find the thermistor is open. On top of that it seems whatever method they use to adhere the heating element to the plate seems to be failing. Several areas near the mounts and solder joints are lifting off the board.I do like that you can add bowden tube fitting to the top and run directly to the printer. The unit itself has a nice seal that would be good for storing filament. It appears the unit suffers from cheap components. I do not have confidence in the fan lasting long either.Personally I'll probably replace this unit with either a homebrew filament dryer or a better quality one from a different brand. For me it's not worth trying to get replacement parts
