Review: Good value, versatile, and excellent performance - 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.
Review: A very well-considered system - I have been drying filament in a modded food dehydrator for a long while now and it has been fine for PLA and PETG, but lately I've been printing more TPU and switching between spools more, so it's gotten to be more inconvenient. I saw the PolyDryer system on YouTube and liked the two-part approach: a "Dryer Dock" for heating and a "Storage Box" for both drying and long-term storage, so I gave it a shot. After using it for a few weeks, I can say it's a solid solution that addresses many of the pain points I had. What it does well: - The base heater unit (Dryer Dock) does the job well without being flashy. The simplified 3 heat settings and an adjustable timer make it rather straightforward to use. The chart with common filament settings being a sticker right on the dock is a nice touch that saves time looking up settings. Really couldn't be much easier than this. - The storage box box seals well and accommodates all my usual spools. It includes rollers for the filament to spin on, plus an attachment for center-hole support. I don't typically need to use the center hole, but it seems like a thoughtful touch. The boxes do stack on top of one another well, but they don't latch together. They don't seem to fall off of one another sitting on the rolling table I have two X1Cs printing on, for what it's worth. - You can feed filament into a 3D printer while you are drying with this system, or while the filament is stored/sealed to keep it dry. This is especially useful for very hygroscopic materials, but it's also convenient for even moderately hygroscopic filament since you don't have to dry it before each print. - During drying the included hygrometer lets you know how wet the air is inside the box since it and the color-changing desiccant are visible through the front of the box. And since the same box is used for long term storage, both act as a nice at-a-glance check to ensure the filament is still dry without even removing it from the shelf. - Two exit holes with included PTFE tubes make it easy to guide filament from the box to your printer. The air in the box stays remarkably dry after the initial drying process. What could be improved: - There's no way to switch the temperature or mode mid-cycle without either letting the timer run down or turning it off and on again. It's not a deal-breaker, but it's an odd omission. - The lid latches are extremely firm. While this ensures a good seal, it might be challenging for some users (like children or those with arthritis) to open and close. **Addressing some misconceptions:** Some reviews I've seen seem to misunderstand what they're buying or have unrealistic expectations. Let me clear a few things up: - There are two options in the listing. You can get either the storage box alone, or a combo with the dryer dock and a storage box. You only need a single dryer dock (though having more lets you dry more spools simultaneously), but you'll want a storage box for each spool you want to keep dry at a given time. This modular approach makes more sense than a single bundled offering because you typically need more than one storage box. - Noise Levels: In my experience, the beep isn't excessively loud, and the fan noise is reasonable for this type of device. I've used other food dehydrators and filament dryers that are much louder than the claimed 41dB. - The LCD display is functional and easy to read from most angles. While it's not a fancy full-color display, it does the job without introducing unnecessary complexity that could lead to failures down the line, and I appreciate that it keeps the cost of the unit down. - Some reviewers have compared this to units with more "granular" temperature controls. In practice, the three-setting approach, combined with the provided chart, works great. The additional settings of other units are really not any different than the dial on a cheap food dehydrator which often leads to false precision rather than better results. This all said, who is this good for? I think if you're willing to plunk down a bit more than you'd spend on a basic food dehydrator this is the way to go. Dedicated filament driers are rarely providing much more than added convenience, but the PolyDryer system is a well-thought-out solution that addresses the real world inconveniences of 3D printing with hygroscopic materials without getting caught up in unnecessary bells and whistles. It's a tool that does its job well without being flashy, which is exactly what I needed, and you might as well.

### ⭐⭐⭐⭐ Drys OK but some issues
*by D***Y on July 8, 2025*

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.
