PolyDryer™

Love the form factor, love the temperature control and love the humidity sensor built in. Very sleep and functional!

PolyDryer 4 pack is excellent value for money , the perfect place to keep your Polymaker filament dry and ready for that next print job , no more messing around trying to figure out if your filament is dry ,in a huury literally print from the polydryer thought the top port.

Excellent dryer with loads of mods available for it, if you’re so inclined. Worthwhile even for PLA.

Dryer seems to work fine but has room for improvement for that price. I think the real value in this system is if you buy a lot more of the storage boxes to make the cost of the dryer seem more worth it.

I now have 4 of these. They are outstanding i live in Florida and when using pteg cf it needs to be dry and these do the job hands down.

Recently purchased a poly dryer, and it’s working great! Also, I wanted to say how great the customer service is… I had a slight problem with one of the boxes and it was dealt with immediately and completely. Very satisfied with this company 👍

I recently purchased the PolyDryer Dryer Dock from Polymaker and I couldn't be happier with my experience. The price was excellent—great value for such a reliable product. The service was fantastic; the team were friendly and attentive, making the ordering process smooth and straightforward. To top it off, the delivery was impressively fast, arriving sooner than expected. I highly recommend both the PolyDryer Dryer Dock and Polymaker for anyone looking for quality and efficiency.

I am very satisficed with the PolyDryer. I used it for the first time a day after I received it and my print job went smoother then expected.

Excelent Product. Very good. Fast Shipping Thanks

The Polymaker Filament Dryer Box is an excellent Dryer and so easy to recharge on the Polymaker Dryer. It's a great addition for my ABS, ASA, & PETG Filaments.

Best option for individual "cereal box" type containers

With all the drying options out there these still work the best for me. Customer support here IS THE BEST! Trust me on that one.

I really like how well the humidity is maintained. I have several filaments that I use sparingly that have stayed at the same humidity for months. Makes it really convenient to use with the PolyDryers. Worth the investment for sure.

Great dryer. Boxes make it easy to store.

Works well. Easy set up and use. Run my filament within the box to my Bambu labs PS2. Maintains low humidity. I’m quite pleased.

The dryer is undersized thermally. It takes forever to dry PLA on 3 bars of power when it is supposed to do it on 1 bar. It will not work to dry anything that takes 60°C or higher. The boxes are stellar, great idea and function. Sad that the dryer is not up to the task.

It may not be for everyone but, it's exactly what I needed. It's affordable and convenient. Plus, it works great with my "manifold" system I made. No issues so far. Love the priduct.

The best feature is one dry AND store the filament roll as well as print directly from the storage container.

The system is good, but not perfect.The elephant in the room is that the dryer is loud and takes hours to do the job. Think hair dryer in the next room over. its not LOUD, but it does constantly draw attention to itself. If you can put it in the garage, laundry room, anywhere you don't have to hear it or just not be home while its running, it does the job capably.The dry boxes themselves work wonderfully for keeping the filament dry for long periods of time.The one hooked up to my printer right now is at 15% moisture and was dried 2 months ago.The construction quality of the dry boxes is much much better than i had expected. very rigid i think it would take a deliberate effort to break one.Other reviewers have complained they are somewhat difficult to open, while accurate i don't think this is a bad thing as it makes a very solid seal between the lid and container. You should only need to open it to replace the spool once depleted. This will not accidentally come open, even if you drop it.Getting the most out of this system. The filament dryer by design will not get hot enough to completely dry the desiccant because that could damage the filament. The desiccant changes colors to indicate how much moisture they've absorbed, after a certain point they can no longer absorb any more moisture. after seeing other reviewer images, i think a commonly overlooked component is drying the desiccant itself before putting it into use in the drybox. simply emptying the beads onto a paper plate and microwaveing them on defrost for 9 minutes works very well and can be repeated as needed for the life of the drybox.additionally this system works best when you remove the drybox from the drying station and cap the drybox after a drying cycle, it does not have a air tight seal to the drying station and leaving it sitting on the dock permits moist air to seep back into the container as it cools.Above i have a comparison of two dryboxes set up 1 day apart, you can easily tell which one i dried the desiccant in before hand and which one i just put together and put on the dryer.My my minor critiques are that the system does not have a rear facing port so if you have your set up like mine your moisture gage will be facing away from the front of the machine.The dryboxes come with a length of PTFE tubing but its a larger diameter than what most machines use so if you want to connect your drybox directly to your printer you will need to supply your own tubingi'd also like to see a future revision with a spot for additional desiccant beads in the rear of the drybox.Overall i highly recommend this system if you can live with or work around the noise issue.

I took a gamble on these after seeing some not-so-positive reviews. They are fairly expensive but evidently they've already lowered the price considerably. These are modeled after a commonly used design pattern in the 3D printing community using cereal containers. You could certainly "build your own". I think what you're buying here is convenience and the capability to use the modular drying system.After running the dryer on the "recommended" stock setting for PLA (level 6 for 6 hours) it lowered the humidity from 48% to 31%.Honestly I'm very satisfied with the purchase and like them a lot. They're easy to build and made of thick materials. I won't be using the capability to print directly from the containers since I have an AMS system, but there's an included tube to make that happen.I use Bambu filament, and they fit when not using the blue "roll holder/tube" thing. I just store that diagonally at the bottom of the container.
