PolyDryer™

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.

Really like the product, it's really well put together and simple of use.I've looked at all the other dryer available around that price range and they all seemed to have the same issue of the touch screen being hard to navigate which is why I picked that one.This is truly a hassle free device.Now with that said, I'm a little bummed out that one of the desiccant packet was already saturated.I've been trying to dry it but it doesn't seem to bring it back to a good enough level.As soon as I turn the dryer off, humidity starts creeping kinda fast.Now it's probably the least problematic issue I could have had.Everything else is flawless. The boxes are super tight, the seals are premium in feel, and I really feel like I got a quality product. I bought an additional box to store my PETG and it's nice to be able to have extra boxes without having to buy an extra dryer.I'm using a Bambu with AMS so I don't need to use the feed through the boxes, but I'm sure with the PTFE tube included it performs as expected.Good job on Polymaker. I will be reaching out to get some extra desiccant though.

The part that displays the humidity is not great but it kind of works.. somtimes... but overall it keeps my asa gf dry. I got 3 boxes and one dryer so far. Probably grab 2 more boxes or maybe one box and a dryer kit. Over all 4 out of 5 stars because the humidity display is a hunk a garbage and for 30$ a box... they could at least put in a better one..

These filament boxes feel very high quality and have proper rubber seals everywhere. All the plastic parts are nice and thick. Overall the boxes have a nice heft to them.The desiccant being colour changing is a nice quick visual indicator of the moisture levels, and having the digital displays showing the humidity levels is also handy to know.You are able to print while keeping the filament inside the box.The little display is removable and uses two LR44 batteries if you need to replace them.Everything including replacing the batteries is toolless.Still waiting on the dryer unit that these boxes should be compatible with.

Makes such a big difference in my work flow. Dry on the PolyDryer, feed the filament directly out of the Storage Box into printer, return filament to storage while never exposing the filament to ambient humidity.
