Polymaker社製PolyDryer フィラメント乾燥機

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。

日本語の手順書がほかの言語と違いところがあります。(ほかの言語ではPETGがレベル２ですが、日本語はレベル１に書いています）

湿気を内部の乾燥剤に吸収させる仕組みその為、乾燥剤を乾燥させる必要があり、それが結構面倒。

ケースは密閉性が高く、除湿剤を一緒に入れておけば低湿度を保てて、フィラメントの保管にとても便利です。 一方、自称乾燥機の方は ケースから吸気して→ファン→ヒーター→ケースに戻されるという、湿気の移動先が無いため意味ないです。 除湿剤を入れずに6時間動かしましたが湿度に変化なしでした。 なんとケースが単品で売ってます。 そっちをおすすめします。

3段階の電力レベルが選べますが最大のレベル3にしてもBOX内温度は45～50℃程度にしかならないので、 PLA専用乾燥機といったところです。 動作音は個人的には気にならない程度でしたが、一緒についてくるシリカゲルが未開封なのに吸湿しきってピンクになっていたのが残念でした。

別会社のフィラメント乾燥機を使っていたのだけれど、乾燥機が分離できたほうが便利だろうと手に取りました。その部分は期待通りだったのですが… すごくうるさいです。かなり耳につく高さかつ大きい音が鳴ります。他社のものの比じゃないです ３Dプリンタの音なんて掻き消えるレベルですし、こんなの6時間も付けっぱなしで乾燥はきついです

Se siente de buena calidad, la idea de poder solo utilizar el recipiente como almacenamiento me gusta mucho, y me ayudó a salvar mi filamento, hay que leer bien que versión compras porque también puedes comprar las cajas por separados.

Works great. I do have some suggestions. It's very loud. Wish I could mute the beep and the lid clasps could be quieter. Also wish I could do a delay start. It would be really handy to time a dry so it's done right when I get home from work.

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.

I needed to dry some PETG filament that had been exposed to humidity (about 50%) for a couple of weeks. At first, I didn’t understand why it wasn’t drying, based on the humidity reading on the included hygrometer. Then I looked at the silica beads and realized they needed to be reactivated because they were dark green/brown. I put them in a heat-proof container and dried them in the microwave about 3 times, 30 seconds each with about a minute pause and a stir in between, and they changed back to orange. I then replaced the silica gel in the container and the dryer brought the PETG down to 15% humidity and has kept it there for days so far. If you’re having problems drying, make sure your silica gel is orange, and reactivate it if it’s not—this is normal. I’m very, very pleased with this dryer’s performance and ease of use.
