Polymaker – PolyDryer – Black

does it's job - Does what it says on the box. Keeps filament dry and is easy to use.

Good dryer - Not cheap, but it's a solid product. I print PETG directly from this dryer, and also use it to dry my silica beads with a 3D printed adapter from maker world.

Polymaker - Works well, helps keep extra filaments dry. Easy to use and doesn’t take up to much space.

Very handy to dry and print from. - I use this for top feeding TPU while keeping it dry for long prints.

Meh. Doesn't seem to dry filament well - Purchased one of these hoping to quickly and easily store filament to quick swap when the Creality Space Pi X4 was drying other filament. Well, not so fast - this doesn't dry filament quickly, or at least not the filament I was trying to dry. Humidity - according to the hygrometer in the Snapdryer - never got below 30%. Hmm; not good. Creality Space Pi X4 ROUTINELY dropped humidity to 30%, and almost always lower, down to 20%. This thing is also . . . unwieldy. It slips out of my hands nearly every time I handle it - that could be, probably IS - on me. Nevertheless, having to wrestle with this when I can easily pop open the Space Pi X4, got me to buy . . . another Creality Space Pi X4. Which has a nice touchscreen and more accurate gradations and information than the lazy low/medium/high settings on the Polydryer. Next iteration should be more accurate and not rely on the hygrometer. Yes, I stiill recommend it, but there ARE better alternatives. It does work.

Avoid - Dries very slightly and the filament still keeps about 20% even after 6h(PLA) and 12h(PETG). Just returned and purchased a serious dryer. Just go for an EIBOS Polyphemus or something else, but avoid spending your money on this one which does not dry evenly at all.

Filament dryer. - Works well. Easy to set up and use. Also using it as a chamber heater.

Dryer - Well made product. Been using for a few month's now. Still running fine.

Dryer - Awesome addition to my 3d printer let’s me dry it then put it in my ams

Great, intuitive dryer - Performs as advertised. Expect to dry PLA for 16+ hours to see a worthwhile impact. Quality is good and is intuitive to use. I wish the beeping could be disabled when pressing buttons, though.

Works great - Very good wish it was bigger it works so good throw a spool in before use it'll be good

A must-have for 3 printing TPU filament - Excellent design and reasonably priced when compared to similar products in the market. If printing with TPU filament, a good PTFE tube directly going to the toolhead would allow for low-friction, no clog/jam printing. I have 3D printed two pairs of Whaleberry shoes along with two handbags with no issues at all.

Great dry box! - Such a great idea for keeping your filament dry and stored safe!

Great Dryer - Love this dryer more out of the other ones i have. It is simple and just does the Job.

Exceptional Value - I love these and will buy more, the dryer also has many uses and model to support drying stuff outside the box.

Great Dryer - I really like this dryer, but it did come with a missing rubber foot.

The best of the best - This filament storage/dryer is the best I have ever used. Was delivered to me so fast. This was an awesome addition to my business..

Nice Dryer - I bought this to dry out and feed some cheap TPU I found. It came out great (first time printing tpu) I was able to dry it out and feed directly from the box to my Bambu Labs A1. There are some great mods for it. I printed some attachments to hold the feet while it dries and a ptfe tube adapter. I plan on trying some more advanced filaments in it with my X1C. Would recommend especially if it’s on Sale. Here is a picture of my tpu beachy for reference

It works - I use this for keeping filament warm while its printing. The storage box is well bulit. I keep engineer filaments in them. Only complaint js the lid is a pain to remove.
