Polymaker Filament Dryer & Storage Box Polydryer for 1kg PA Nylon PLA PETG

製品自体もよかったが、Polymakerのカスタマーサポートの対応がとても素晴らしかったです。現在の乾燥剤の色は仕様が変わって乾燥しても青色ではなく、オレンジ色およびダークグリーン系らしいです。説明書の＋−で時間をリセットする機能は搭載されておらず、説明書が改定されていないだけらしいのでお気をつけください。一度乾燥させてフタを密封すれば長期間乾燥状態で保存できますし、maker worldで改良できるパーツがいくつもあるので、とてもいい商品だと思います。

Drying your filament is up there with washing your build plate - it doesn't seem like something that will have a huge effect but it can make a significant difference to the quality of your prints and whether they succeed at all. Failed or low quality results mean wasted filament, time, and electricity costs. Don't think that adding silica gel cuts it - that can change the relative humidity which affects whether the filament will be absorbing moisture or not, but if it's already too damp it's not going to really dry it out.Unlike most other filament dryers that only handle the drying part and leave the storage as a challenge for you to solve this is a clever modular design that separates the dryer from the storage box so once the dryer has been used to remove the moisture it's immediately sealable for storage and can be used directly from the sealed box. It really is neat, compact, and really works well as you can see from the 20-minutes in shot and the final humidity compared to the external reading. A benefit of this is that you can dry your filament way ahead of when you need to use it, rather than adding an extra 6+ hours before you can print the thing you want to.It works great as a single filament dryer but the real value comes from buying some additional boxes that you could use to store filaments in, at least the more "thirsty" hydroscopic ones such as PETG, TPU, and nylon.There are lots of mods available to print from printables or makerworld to add some venting, allow the drying to dry two boxes at once, connect two dryers to a single box (turbo mode?), stack boxes, or even use the boxes directly to feed a BambuLab AMS lite.The heater is fairly quiet in operation and is simple to use, with the temperature levels and timescales on an information plate on the top of it. The storage boxes feel well made and robust and should hold up to many years worth of use, so they are definitely an investment - getting a few extra provides more benefit over just having the one that comes with the dryer itself.

Set to PETG to dry for 6 hours, but humidity drops 2% and temperature rises to max 40 degrees.

TLDR: They work great for the enclosed python ams. I run 2 in the back of each of my python units. I hate the power bricks. I’ve melted a spool on accident on the highest setting. I like the modularity. I haven’t had issues with storage in the containers.Long/in depth part:I don’t have exact measurements from a thermometer, but considering I melted one of my spools (the spool, not the filament) when having it on the highest setting to dry, and the box discolored/warped as well, I think it gets hot enough. Given the spool was very large because it was a tpu spool from geeetech so maybe that caused issues? The little blue spool holder thing didn’t even lift the spool but it fit in the box just fine so I went for it. Maybe I got units out of spec compared to everyone else? Whatever the case, they work awesome. They’re all mini dragons of filament drying goodness in my setups.I have 5 of them. 2 for each of my python ams units (in the back of the enclosure), and one freestanding for the one off spools I dry every once in a while. The freestanding one is the one that did the melty bit above.I also bought these for my python ams and have been able to sustain temps past 120°F (what my internal thermostat can measure to. I got cheap ones okay?) at the front of the unit (2 dryers in the back on full throttle), so that gets plenty hot too. With all 4 units running (my pythons are stacked right on top of one another), things can get toasty in the upper unit. Given it takes 2-3 hours to reach temp, but sustaining past that is no problem.More exotic filaments that are needing the additional heat I do in the boxes on the single. It’s just easier to keep them in the boxes as I use them.I think they work fine for what they’re advertised to do and as a modular system. Yeah it’s not like those crazy expensive 4 spool units but it’s good for the money. I always dry longer than recommended just because it takes time for the entire container to get up to temp.My only complaint is how big the power brick is. I can only use 1/2 the plugs on my extension cord and I don’t feel like doing shenanigans with replacing them with something else. The biggest mod I did was removing the sticker with the settings (it was an accident at first thanks to tape, but it looked good enough to where I decided to roll with it). That way they’re just black units at the back of my ams. The single one still has it on, and the ams ones I never run on any setting but the highest unless I see significant issues.

Comes with pods for desiccant. Works as advertised. Probably work on spools up to 1kg but not much more. I believe they have a larger one for the large rolls
