Polymaker PolyDryer Type A - 3D Filament Drying & Storage Solution - Compatible with 1.75mm & 2.85mm Filament - Protects Against Dust, Moisture & Pollution

Works great in my home made python case,

Great for storing and feeding TPU.

Honestly thought the Polydryer box would be a bit of a gimmick, never really considered the impact of moisture on filaments until I had some PETG that was a stringy mess. A few hours of drying cured the issue and since then I've stored it in the Polydryer and it's stayed around the same humidity in the box and greatly reduced stringing. I'm sure for storage the same could be done cheaper DIY but I love the convenience of being able to dry the filament and store is all in one system.

I bought this in order to keep my 3D print filament dry, and this box does this very well. I haven't had any problems with wet filament since I started using the box. The box comes with a small amount of silica gel balls and a little storage area behind the hygrometer. The hygrometer seems to be fairly accurate but filling the storage area with the silica balls can be a pain and you really do need to be careful or they will go everywhere. The lid snaps shut tightly, which is what you would expect in order to keep more moisture from just entering the box as fast as it is removed by the silica. There are also small plugs provided to close up the holes where the filament can be fed through from. I did need to be careful at the start as something kept getting snagged and the filament would stop feeding correctly, but after changing the feed angle that seems to have been resolved. Overall the polydryer box is a good, sturdy box made of high quality materials - unlike a number of other dry boxes which are basically food storage containers with holes poked in them.

Good price for a drybox, I don't have the drying unit but these boxes are quite good for the price, lid is hard to clamp on though and you may want to put some more silica gel beads in the bottom of it.

Excellent 👍

I purchased one of these a couple of weeks ago and it worked perfectly — the product itself is excellent. Unfortunately, I couldn’t use this particular order because, unlike the previous one I purchased, it did not include a UK 3-pin adapter and only came with a US adapter. The main reason for the 1-star review is the lack of customer support. I spent over two hours trying to contact the seller but could not find any way to do so. There was no “Contact Seller” or “Report an Issue” option available anywhere. As a result, I’ve had to spend an additional £22 purchasing another adapter that includes the UK 3-pin connection I require. Very disappointing experience considering the actual product seems good.

Works fine for what I need it for. Only 4 stars as it doesn't come with a UK power supply and had to purchase a US to UK adaptor for £10

I needed a drybox for 3DXtech 2Kg Carbon X spools, we use a lot of it here in the shop, and these spools are 300x100mm. None of the other 2kg+ spool holders fit. At least none in my price range. I like the upgrades from the smaller ones, and the adapters for the drydock are fairly easy to 3d print if you have your bridging settings dialed in.

Nice boxes Plenty space

Se siente de buena calidad, la idea de poder solo utilizar el recipiente como almacenamiento me gusta mucho, y me ayudó a salvar mi filamento, hay que leer bien que versión compras porque también puedes comprar las cajas por separados.

Works great. I do have some suggestions. It's very loud. Wish I could mute the beep and the lid clasps could be quieter. Also wish I could do a delay start. It would be really handy to time a dry so it's done right when I get home from work.

Outstanding product. Packaged very well and secure for shipping. Printing mostly PETG, they keep my filament in a perfectly workable state after dehydrating. The digital hygrometer is very responsive and accurate enough for the use case give or take 1-5%. They are nice and compact fitting nicely on shelving for storage. I am a little worried about the clamping sides as they are slightly tough to snap on and engage. Putting the lid on slightly wrong may result in breaking those clamps. I would keep an eye on this. The filament holes on the top and front are great for their use case. I look forward to purchasing more of these as my color library continues to grow. Highly recommended 5 Stars.
