Features
- CONSISTENT DRYING PERFORMANCE - Designed to help keep filament in better condition for printing, Polymaker filament dryer supports more stable print results by helping reduce moisture-related issues such as stringing, bubbling, clogging, and layer inconsistency. The drying dock promotes even airflow and controlled heating, helping your filament stay better prepared before and during use.
- DRY, STORE, AND PRINT WITHOUT BREAKING SEAL - Built as a connected drying and storage solution, this 3D filament dryer lets you move from drying to sealed storage and direct filament feeding with less exposure to ambient moisture. This helps lock in dry conditions between prints while keeping filament ready to use when your next job starts.
- HUMIDITY CONTROL & MONITORING - With a storage-box-based protection setup, our Polydryer makes it easier to monitor, track, and maintain dry conditions for your filament. A built-in hygrometer helps you judge filament status with less guesswork and supports better day-to-day management between print sessions.
- COMPATIBLE WITH A WIDE RANGE OF FILAMENT TYPES AND SIZES - Made to support common 3D printing materials, this filament dryer and storage kit works with PA Nylon, PLA, PVB, PETG, ABS, ASA and TPU, and is compatible with 1.75mm, 2.85mm, and 3.00mm filaments. One setup helps cover both drying and storage needs across more everyday printing materials.
- HEAT + SEAL + DESICCANT PROTECTION FOR ONGOING MOISTURE DEFENSE - Instead of relying on a single step, this filament storage box + Dock combines heated drying, sealed storage protection, and desiccant support to help maintain better filament condition over time. This integrated approach is designed for users who want a more complete moisture-control routine before, during, and between prints.

I paired this with some color-changing desiccant beads and an adapter that allows you to dry two filaments at once, albeit more slowly (search online for PolyMaker PolyDryer - Double Barrel Mod). Works great.

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.

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.

On the whole, the dryer module is useable to me although not as good as I expected. I purchased the dryer and box and an extra box. My purpose was to be able to dry higher temp filaments like Nylons and ASA that my little Sovol box couldn't plus provide a dry box while printing actively with my printers without having to wait for long dry cycles. The dryboxes being able to be separated from the dryers and stored separately is one of the pluses with this drying system. It does reduce the cost of storage of opened filament by only having to purchase a limited number of dryers while using more dry boxes. For PLA and PETG and TPU filaments it dries well. For materials like ASA, ABS or Nylon, not so well. After test drying Polymaker's own PA6-GF25 filament I'm not too impressed. 1st, the elephant in the room...This is an expensive way to dry and store filament. $80 for a dryer and 1st box then $30 per box after that! I'd suggest you dry each roll and either use it immediately in its box to printer or store in some air tight resealable bags with desicant. Storing one box per roll of filament can get real expensive with these. The dryer has very limited air movement into the boxes. All the pictures and implications show air movement in a vertically circular pattern inside the box. I found that it pretty much lightly flows from input directly to output ports only in the bottom. Only residual heat goes to the top of the spool and isn't circulated well at all. Moisture tends to collect in the front desicant and hydrometer and in the top lid. This gives a false impression of what the filament moisture actually is. You're really measuring the desicant moisture. Also the venting holes on the lower sides in the dryer arent venting out most of the moisture which stays trapped in the desicant or top lid. That will go back into the filament when the dryer is shut off and the box is removed from the dryer and sealed. Now that would be fine if you could quickly and slightly open the box to rotate the spool or open a vent on top. But the snap on top held by two huge clips are difficult to snap open at best. Also there is no motorized spool movement either. So the spool isn't heated or dried uniformly. Opening or closing the large top clips requires a good deal of force and makes a loud snap sound like you just shattered plastic. I get the impression that the clips (or worse yet) the box itself will eventually break after significant opening or closing. The heat inside the box generally doesn't get much above 50 degrees C even on it's highest setting. Its also very inconsistent in different areas of the box. Only after two or three hours of operation can it reach close to 60 degrees C on the highest setting near the box's heat inlet. Many advanced filament types need hours of 70 to 90 degrees C heating to dry properly. This box can still dry those filaments somewhat, but they will require many more hours of drying to do so. I did dry PLA just fine at the lowest setting over time. But PETG and TPU needed the second heat setting for a good deal longer than specified. But at about 12 to 18 hours they dry. I was unsuccessful at getting Polymaker's own PA6-GF25 or Qidi's UltraPA to dry enough. Even the highest setting of the heater for 24 hours wasnt enough. I could get them down to about 20% readings until the dryer was shut off and the bottom air ports were capped off for storage. But then the readings would slide back up to about 30% within a day when the trapped moisture in the box and the desicant went back into the filament. Also, I wasnt thrilled with the 3 levels of settings as one two or three nozzles. I want to see settings geared to temperature settings and durations not some arbitrary 123 nozzle kind of choice that I need a chart to decipher. Give us heater temp settings with durations. And the displays both in the dryer and box are terrible! Both displays are completely unviewable at any angle other than straight in front of the units. Move even a foot or two above, below, or to the left or right and you will see all 8s and all text displays shown at once. It means you spend a lot of time having to position your body down and directly in front of the displays just to read them. Poorly chosen displays! The fan noise of these is somewhat moderate. If you have it in a quiet room, sure it will be very noticable. But most of us will have these next to printers with several fans with much louder volumes than these. In summation, this dryer and dry box do work and will dry most low to moderate temp filaments within a 12 to 24 hour period. But I was disappointed in the fact it did not dry my higher temp filaments well even after 24 hours. And the moisture venting being below the dry box is not very effective at removing the moisture from the box. It needs a better top of the box vent that can be sealed off when stored. You might also find you will have an extra cycle to cook the installed desicant in an empty box to recharge it or that moisture will just return to the filament. I'll probably keep the dryer and two dryboxes but will only use them with PLA, PETG or TPU. Certainly not worth the $110+ I paid for them to be able to dry advanced filaments. I'll now have to spend more money trying another dryer system that can actually dry advanced filaments within a 24 hour or less timeframe.

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.

Problem 1: Desiccant arrive saturated and unable to use out of the box. Problem 2: Once desiccant was dried I opened and loaded a fresh spool of Fiberon PA612-CF into the PolyBox and set the PolyDryer it to the appropriate heat level as directed by the posted instruction. My first print was going to take a few hours so I set the timer for well beyond the print time to account for moisture absorption during printing. First print came out awesome! But that was the last print to be awesome. During the print I noticed the PolyBox hygrometer rising from an initial 10% humidity to 24% at print completion. I found this odd. I removed the PolyBox from the dryer base, rewound the spool, closed the filament holes and put the box back on the dryer for 18 hours (as per the directions) to dry out the filament. During the 18 hours the hygrometer went from 24% to 21%. I removed the box from the base and installed the bottom plugs. 24 hours later the hygrometer read 10% again and I began another print. *This is where it all went bad. I began another print of the same model and the stringing began immediately. I could hear the tell-tale sizzling sounds of wet filament coming from the hot end. How could I have WET filament after following all of the directions from PolyMaker regarding proper handling and drying of my filament? I dried the filament once for another 18 hours and had the same stringy sizzling mess as before on some retraction calibration prints. I tried it once more for 24 hours and the print quality only continued to degrade due to wet filament. I am very disappointed with the whole system. Considering the cost being much higher than other dryers it only added insult to injury. I am now left with a garbage paperweight that does nothing but take up valuable workspace and filament that should have never reached the point it is at now. DO NOT BUY.

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.

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!!
