This is a nice system. The dry box can be exasperated from the dryer and it holds the humidity well.
I’m not impressed with the dryer, it works, but took two passes to get a roll of PETG down from 58 percent to 28 percent. I was expecting it to get down to 20 or less with one pass.

I had a really wet roll of nylon. Popped it in the box on high for 12 hours and it printed great. The humidity sensor seems pretty accurate and the beads indicate when they are full of moisture. Can’t wait for these to come back in stock so I can order more. I like that the dryer can be removed from the box so you can just get more boxes.

This dryer has worked flawlessly out of the box. The settings are easy to maneuver, the quality of the product is great. Make sure you follow the recommendations in the guide and you will not have any problems using this dryer. Very happy.

They work great and I will be purchasing more boxes. Initially I tested on an old roll of PLA that would not even feed into the printer without breaking off. After a 24hr run, it’s now as flexible as new and at 24% humidity. My only minor complaint is that the power supply is the ‘on plug’ type and it takes up a lot of real estate on a power strip. Not a big deal.

This became my go-to filament dryer – to the point that I am hooking up directly to the printer.

I really like the modular design. Storage capability + keeping it sealed and feeding the printer. Did some testing and found it reaches 60C. Pretty good.
It also can give a nice little bump to your chamber temps of a enclosed printer without active heater. Threw the base in my K1C bottom, ran it for 30 minutes then printed some TH3D ABS warp free. So I imagine this is a good device to be modded.

The Polydryer system is a great concept, but poorly executed.
The dryer base leaves a lot to be desired, it doesn’t come close to producing the industry recommended temperatures for the filament groups.
Polymaker claims 50/60/70ºC for the 3 levels, but those are AT the heat output grille, not in the central volume of the box where it counts. Air cools off significantly when it expands out into the box.
I measured roughly at the spool center height, and about where the surface of a half-spool of filament would be, and got 40.5/48.9/57.2ºC – rather pathetic. This poor performance has been noted by a couple of YouTube reviewers as well.
Fortunately, there is a simple mechanical tweak one can make to bring each temperature much closer to the desired 50/60/70. Ya need a phillips screwdriver, open it up and move the thermistor as far to the right as the wire will allow. You’ll get about 5-6ºC more at each level.
Even then, the heat isn’t distributed evenly. Air moving up & over the top of a spool of filament looses about 5ºC in transit. So the side of the spool nearest the outlet gets hotter than the side opposite the outlet.
It’s really up to Polymaker & FabNotion to address these shortcomings.
