Review: Long review to explain why I chose it and why I love it. - 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!!
Review: PolyDryer with PolyDryer Box... works as intended - 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.

## 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.

### ⭐⭐⭐⭐⭐ Good value, versatile, and excellent performance
*by G***. on December 29, 2025*

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.
