## Description

desertcart.com: Polymaker 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 : Industrial & Scientific

Review: Good container - The storage container is great. There are two ports for feed tubes, so you can pint right out of the container. The included hydrometer makes it easy to see moisture levels. There is a silica pocket within the hydrometer, that helps to maintain proper levels. At the bottom of this container, there two plugs, that can be removed, so the container can be placed on the dryer dock. I have later bought one more container, this time with dry dock. Dry dock does not work very well. It takes long time to dry the filament, and moisture levels never go below 30%. The container however holds moisture levels low, for long time, if loaded with dry filament.
Review: Exceeds all expectation - A very well engineered product that feels solid, looks great and works great. I purchased just the storage container and filled the bottom with desiccant. The included length of poly guide tube is a nice touch, it slid perfectly over my printer’s guide tube. Now I leave a filament loaded in the printer all the time and it’s entirely enclosed.

## Features

- PolyDryer by Polymaker: Your ultimate solution for 3D printing filament drying and storage, protecting against dust, moisture, and pollution. (PolyDryer was designed and co-developed by FabNotion.)
- Dry & Store: All-in-One Solution: Printing with moist 3D printing filament can cause issues like stringing, clogging, poor adhesion, and layer shifting, particularly during high-speed printing. PolyDryer effectively mitigates these problems by pre-drying the filament, enhancing print quality and minimizing the impact of external environmental conditions.
- Unique Modular Design: PolyDryer features a modular design with two units: the Dry Dock, which maintains a stable temperature for quick, even drying using a precise heat control system and PTC heater, and the PolyDryer Box, which provides superior sealing and continuous filament protection. You can add multiple PolyDryer Boxes to one Dry Dock, ensuring your filament is always ready for your next project.
- Efficient Drying & Superior Sealing: The 360° airflow of PolyDryer ensures even drying of your filament spool without causing damage. It is compatible with all popular 3D printing materials and features three preset power levels. With exceptional sealing performance, the PolyDryer Box protects your filament from moisture that could ruin your prints.
- Versatile Sizes & Universal Compatibility: PolyDryer accommodates various spool sizes up to 1kg and features a central holder for smooth rotation. It supports most 3D printing materials, including PLA, PVB, PETG, ABS, ASA, TPU, PA, PC, PVA, and PolySupport for PA12. Additionally, it works seamlessly with filament diameters of 1.75mm, 2.85mm, and 3.00mm.

### ⭐⭐⭐⭐ 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.
