3D Printing Filament Dryer and Storage Box - PolyDryer and PolyDryer Box for Filament Drying and Sealing with Heat Control, Compatible with PA Nylon, PLA, PVB, PETG, ABS, TPU 1.75mm 2.85mm

I like to leave a review when one is worthy, and spoiler alert, this will be glowing. 3D printing is loads of fun with unlimited creativity, but there is knowledge that is gained along the journey. One little tidbit is that filament needs to be dried if you live in a humid area...And some, in not as humid as you would think area. After looking at the design of several devices from Creality, Anycubic, Sunlu, Comgrow and Giantarm (Filament Bags) I finally settled on the Polymaker. As I own an Ender 3 S1 Pro, I'm currently only feeding one filament at a time, so a multi-strand dryer while cool, didn't really make sense to me. I also am limited on permanent space. This lead me to the reduction of choice to single spool. I chose the Polymaker because it allows me to store the dried filament separately from the drying system (Which is partially built-in). The ability to see the humidity level in the box was a big part of my choice and know that the desiccant changes colors so you know when to recharge it. Yup, the desiccant is reusable, not just an individual pouch. And if that wasn't enough, each case comes with a good PTFE lead pipe so you can draw directly out of the case. The case itself is sealed really tight. The seals on the feet (Where you set it on the heated air flow device) also seal very well and have a rubber non-slip base as well. They stack very well too. As for the performance, well it was way better than I expected. When I received the unit, I had some prefoamed LW-PWA that had been out in the open air for weeks. When I put it in the container and let it sit for a few hours, it showed to be at 54% humidity in the container (UP from the 49 when I loaded the filament). I ran it on the forced heated air base for 6 hours as instructed. It dropped down to 41% after the first run. I decided to run it again, just for the heck of it, and it came down to 36% after the second run. After leaving it overnight it was down to 29%, just using the desiccant. Total reduction from 54-29% in less than 24 hours (About 22 hours total). I was very happy with the 25% reduction in that short period of time. Each box can be used without pulling the roll out. There are two options: 1 you can use the ball bearing rollers that are setups in the case, and they are so well designed that in an empty case, the airiflow will turn them, OR you can use the included roll post that ankers very well in the side of the box. The PTFE tubing allows for either vertical or horizontal tapping of the filament. I have minie setup to feed from behind the printer, but may make some changes in the future. Regardless, I know that the system will support whatever setup I choose. The base unit is very easy to operate, has recommendations for the filament drying temps and times listed, and allows you to set it according to that, or you can just set it for constant untimed running if you really wanted to drive it down faster. The foot print is very small as compared to the others I looked at. The power source is a bit large, but designed to not take all the slots on your power strip if using one. It will take up 3 depending on how close together they are. Overall I very much love the design of this unit, along with the well thought out engineering. The whole system seems very sturdy and strong which encourages me on its longevity. The only change I made to the setup was the desiccant color. III already had 2lb of Blue silica gel which turns to pinkish red, so i used that vs the orange that turns green. This was done for two reasons. 1. the color of the box is Blue/Black/Clear and it just looked better. 2. having the silica gel turn Pink/Red just made more sense to me with Red meaning "Stop" in my mind. Thank you for bearing with me ini what is the longest review that i have written in a long time. Should you choose to purchase this system, and it is a system, it wont let you down. Print Happy Days, and everyone will love your prinits!!

The Polymaker PolyDryer with PolyDryer Box combo works as intended. It does in fact heat up and dry out filament reasonably well, seems well made, doesn't make too much noise and is reasonably compact with a modular design. The base unit does the work, and the removable, sealable Box unit can store your dried out filament indefinitely with a hygrometer and desiccant visible with the clear box. So, what's not to like? according to The Internet, it's an overpriced, underperforming monstrosity. In my observation: The Bad: 1-The removable Box unit has a top lid with unusually difficult to operate latches. 2-The removable Box unit has two easily misplaced bottom sealing plugs that must be removed when placing the Box unit onto the PolyDryer unit. No provision is made for holding these two plugs when not in use. 3-The instruction manual is a bit sparse with no mention of actual intended temperatures, humidity or power levels. Also, worryingly, it advises to unplug the Power Supply from the wall when not in use. This seems like an unusual precaution in modern times and calls into question the quality of the Power Supply. 4-The LCD displays in both the base unit and the inboard Hygrometer are difficult to read off-axis. 5- No actual temperature displays are included, just a relative heating level selector and timer on the base unit and a Hygrometer inboard of the Box unit. The Good: 1- It works as described and expected with easy to use controls. 2- While hardly silent, the sound is reasonably unobtrusive. 3- The Box section seals really well and has an inboard Hygrometer and Desiccant container, the Desiccant itself being re-usable and replaceable. 4- It is reasonably compact and there modular Box units are sturdy and well-sealed. Neither good nor bad: The Power Supply is external, and thus replaceable. Odd that it is not built in, but whatever. Not very stylish at all. Just functional. Not especially cheap or expensive. In comparison to my first Filament Dryer unit, an eSun eBox Lite: The Polydryer works better and allows for sealed storage. So far has lasted longer as the eSun's heater failed within the first few hours of operation. The eSun is easier to open and close and looks nicer. Both have very similar controls and displays with three relative heating levels. The PolyDryer costs more but works better. The eSun manual is not quite as sparse, with actual intended temperatures, power and humidity levels published though probably wildly optimistic.

Great value and performance. The dryer portion doubles as a desiccant-gel-bead dryer with a 3D-printed attachment. This dryer and storage box are a must-have when printing with ABS, ASA, and other hydroscopic filaments that require active drying and dry storage. The ability to print with this filament without opening the container after drying is a huge plus. I will be adding more storage boxes to my collection in the future for use with TPU.

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.

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.

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）

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。
