Comgrow Filament Dryer Box for 1.75/2.85mm PLA PETG TPU ABS

This filament dryer made a noticeable difference in my print quality. It’s easy to use, heats up quickly, and keeps filament dry while printing, which helped reduce stringing and print issues. Simple setup, quiet operation, and works great for everyday printing. Definitely worth it if you want more consistent prints. Color quality, material quality, it’s all perfect with this.

Very nice dryer, I would like to say that I wish it had a 4 hour option, lowest is 6 hour, but I guess higher is better than lower. I only use it at 50c and its been working great, comes with plugs to keep moisture in. Looks super nice on my desk, doesnt take up much space, Durability is probably a 9/10, lid feels a bit flimsy but its not like its gonna take a hit any time soon. I printed tpu while drying it and the bearings helped gret with the extrusion, no issues for me. overall great product for 3d printing.

I just started 3d printing and got the cheapest I could find. First off this has a major design flaw the bottom of the dryer gets very hot because there is no air flow at the bottom of the case! This will get your table quite warm and possibly damage it over time if its plastic or laminated! I had some stick on some rubber feet to elevate the unit and that fixed the problem instantly! I later bought some silicone speaker isolation feet (heat resistant and way taller) to replace them for more airflow and the bottom only gets warm now, I just stuck them over the original 3/4 sized anti skid pads. This is a very bare bones unit but nice, the model I received has 4 filament holes 2 on top in addition to the 2 front like as pictured and apparently I have the new firmware which now has 50C as the starting temp and 48hr max timer, yay! Got to be frank this does not look like its gonna last long its cheap looking but it does what its supposed to! You can not rely on opening all the filament ports to let moisture escape you have to crack the lid with the locking clamps as a prop to dehydrate otherwise it takes forever. There are a bunch of printable mods to improve this unit which look fun to try. So far I am printing with one spool in the dryer and a spare just sitting there drying out with whatever silica packs I can fit in the centers of the spools to recharge them...rollers work fine and the silicone filament hole grommets don't impede the flow too much but I'm going to replace them soon, like I said there are so many videos on this unit to mod it! One star taken for the horrible heat problem on the base where you HAVE to buy feet, otherwise nice unit to fiddle and play around with.

Great for price

This is my second purchase of this dryer because I liked the first one I bought. it works extremely well, easy to use

Very happy with this dryer, my prints come our so much better.

Good product, will dry up 2 spools of 1kg. Nice and functional screen but NOT touch screen (only 4 keys are touch) However it is not suitable to dry AND to spool out at the same time. I tried to unspool via the 2 provided ports, but it often jam inside... I tried two vendors and no luck unspool. So use it only for drying up.

I wasn’t sure how well this would work I’m still a novice and this price was far below most others … sometimes you get what you pay for - this time I got something well worth every single penny- works beautifully- instructions and operation was easy- easy enough that I really didn’t need instructions. Works well saves me way more than I realized including hassle. I like the way it locks and vents the moisture when drying - I did observe a tiny bit of condensation on the lid but we keep our thermostat set on arctic and the filament I was drying had been left out for quite a long time- the $40 I spent on this saved me from chucking $150 worth of filament . It is a dryer not just storage. I just dry it then store what I’m not going to use anytime soon in vacuum seal bags. What I did not realize is how different freshly dried filament saves on frustration, colorful wording, frequent reprints…. I love how I needn’t even remove it from the box with a place to pull the filament through. I’m beginning to wonder if perhaps I shouldn’t just but another one to save time but I don’t print a a hobby but for parts and pieces and to use for casting. This is so so helpful- if you are teetering with the decision- I wouldn’t bother with the more expensive ones this one does the trick. I’ve used this more than once btw-,probably a combined total of 72 hours dry time. Even if you need a larger capacity - it’s still cheaper to purchase two of these than one of the four spool driers. Well worth it.
