Compact Filament Drying & Storage System (Polymaker PolyDryer)

Make the letters recessed and you can repaint them easily yourself. Or they likely wouldn't tear in the first place.

just need the base LOL ... cut some holes in my current setup and this would rock... OUCH 80$, I built 20 for 6$ each...

I just received one this week and it came with the orange desiccant. I dried some Overture Turbo PLA and it only dried to 33% after 10 hours. I also fits in my Prusa MK4 enclosure (just the storage box).

why did they make that box so small? STUPID.

Please include Fahrenheit temps in your videos! You don't need to put them in the script, flash them on the screen when you mention the degrees C. Thanks!

It seems nice but the dryer is expensive...

I had one of these for a day or two. It's complete junk.

If they release a second version with mentioned additions as well as to select the temperature in 1 degrees steps up to 90C would make it a beast of a system. The cherry on top would be getting rid of the decicant stuff and use this electric membranes CNC kitchen once made a video about. It would end up more expensive overall but feels like an endgame solution for drying and storing all sorts of filament. Oh I forgot make them a bit bigger the boxed to mache even go to as big as 3 kg spools but even 2 kg would be a huge improvement.

Reguarding the beep, I have opened more than a few electronic devices in my lifetime in order to rip the speaker out with a pair of pliers (or gently snip the leads) I have not done that with this box but removing the speakers in this way has never caused me any problems on the other devices I have "modified"

Great video, love how descriptive he was and how thorough you were in testing and getting those little qwierks and pros out to the public!

measuring the temps without a spool in the box means almost nothing concerning how effect it heats the filament. None.

Thanks for the video. This was super helpful. I just received mine yesterday and it appears that they took your advice into account and they have replaced the blue desiccant with orange desiccant. The question I have for you is how much air movement comes off the fans for you? I guess maybe measured in CFM, I noticed on my unit that the air movement is barely noticeable and I have a lot of moisture buildup inside of my dry box while it’s running. Not sure if I got a bad unit or not, but the air movement seems barely adequate.

Seriously been looking at these... thanks for the video

Poly started with the unheated dryboxes for 180 bucks or something right?.
This is a improvement.
Too bad its aliexpress hygrometers and a simple ptc heater with thermalcutoffs.
Ptc is fine but it sucks they use the cheap crap hygrometers.

Can't seem to find it anywhere in stock... Is this device available in the United States?

I just don’t see this as viable option for long term storage. $29 to store a $13 spool! As another commentator said, A big airtight totes with desiccant is more economical. I have two big Yeti coolers that I use. If my fridge/freezer fails I’ll dump out the filament and save my food. Then dry it two at a time in my EBIOS.

Thanks the the video , that is really helpful! I have one quick question: after printing, do I need to open the box to tidy up the filament before I can store it as a dry box?

Thanks. Good video.

once again a great video
thanks for your insights

The fan inside it looked pretty standard. Maybe a 40x25/20? Noctua has 4020 fans, so maybe a fun little project for one with this dryer to switch the fan for a noctua? Because imo 52dB is pretty bad for a dryer.

Very funny, 1 box cost more than a spool, it could be a solution if you own just a few spools, I own more than 300, that will cost me ~10'000$ in boxes.... Plastic bags is the BEST solution.

Modbot, you should review the Smart Orbiter v3.0 please!

What are the dimensions of the storage box? I am not shure if they fit my cabinet.

I got my Polydryer and extra box this week, and TBH I am dissapointed. The hygrometers are all over the place, and after numerous sessions i cant get the boxes with PETG to go below 25% humudity, swapping the hygrometers also makes it seem the readout is completely random. I have seen reviewers mention that Polymaker made adjustment to the stickers to have them not bubble up, but after 2 days of use my unit is showing that exact "defect". Is 3dJake selling old stock maybe?

Great video and review! As someone with a food dehydrator and a dozen or so cereal containers I'm a little jealous but as you touched on, the money I've saved equals more filament I can buy; which equals more inexpensive dry-boxes I need for storage which saves me money which equals more filament I can buy which equals more...

At 30 bucks for the box it's not really viable as a storage solution. I'd have to spend a couple thousand bucks to store my spools with this. So I'm going to stick with vacuum bags that just cost about $1.50 per spool. But I might get one or two of those units for drying while printing.
If they could figure out a way to lower the cost of the box to the price of cereal boxes it'd be a really nice storage option too.

I currently store my filament in cereal storage boxes that are very similar in shape to the box. I wonder if there would be a way of adapting these (cheap) boxes to work with the dryer and hole plugs.

I really like this, it's modular so you can quickly swap out boxes, it keeps your filament dry once dried, and looks like the core functionality is well thought through.

I do have a question though, my printer feeds from the rear, is it possible to place the hygrometer so that it is on the other side of the grommet, allowing the filament to exit the box in the back rather than the front, while retaining the ability to read what's on the hygrometer?

I really want to like this system more. I think it looks pretty good, it seems pretty well thought out. But the price. I just can't get over the price tag. If you wanted a bunch of these boxes Lets say, 10-15 in order to really keep your popular filaments ready to go, its a pretty hard cost pill. If they were like, $20 a piece for just the box, I think I could get more behind it, something about that $30 feels too high. But form and function wise, it looks pretty cool.

I've gone with the PrintDry boxes for storage as about $12.50 each. $30 each is WAY to expensive. Why no thermostat? With the heater they use, they control the power with the fan speed. No thermostat to worry about but not very precise. Probably OK for a dryer box. I have almost 100 storage boxes, so $3000 for storage? I don't think so. That is more than the filament in them.

It's amusing that the cobalt chloride is only carcinogenic if you eat it, because I don't think that's your biggest concern if you're eating it SuperVinlin

Completely with you on the cost thing though; I'd love do you get some of these for their convenience, but aside from the fact I can't afford them at the moment, I would find it hard to justify the cost even if I could.. would be nice if they at least had a buy in bulk option like you mentioned

I like the concept of separating the dryer-unit from the box(es) very much.
But too expensive.

Do you think these heater units could be attached to the bottom of a modified AMS unit from Bambu to make an ams that also dries?

looks more DIY than most diy solutions

if it can just use hinge and some magnet to close that hot air vent hole thing at the bottom and can just put it on that drying stand without have to take out that feet cover out
it 90 euro price is quite high too

I like the dry box portion. not 100% ford on the heater due to cost.

I had been debating purchasing an Eibos Polyphemus for several months and I'm glad I did. @MandicLabs posted a reel on his Instagram about the Polydryer and I immediately knew it was the better choice for my use case (rarely use an entire spool at once) so I ordered one from TH3D as fast as I could. Glad to see some more positive reviews though I do agree with the cons (beep and no exact temp).

overpriced and overengineered cereal box... sorry but definitely not for me

Yesterday I uploaded my 3D printable version of this box. If you use a cheap filament you can save a little bit of money per box. However, my intention was to improve a few features that are missing on the original or that I don't like. For example, to make the box stackable or to replace the very tight closure with a better one. All in all, I like the option of being able to simply place the box on the dryer.

Polymaker is one of those companies where I'm not sure the higher price really deters me...they have been very supportive of the 3D printing community and make quality products. I wouldn't use a large number of the boxes for filament storage (the large, airtight plastic tote I got from Amazon for $25ish holds many kilos and has a sealed, rechargeable, indicating silica gel EvaDry unit rolling around inside) but the dryer does beat the Sovol dryer I got bundled with my SV06 Plus in features including max temperature.

It was a lot of fun helping to develop this dryer! Glad to see it's getting overall good reception.

4 of these for 320 or sunlu s4 filament drier for 190 i have the sunlu filament drier direct feeding 4 printers and never have any issue with stringing and it looks much better

It's a good solution but it's too expensive compared to other alternatives.

So is the PA/PC settings hot/long enough to actually dry PA/PC?

Did you test the hygrometer? Another channel found the ones in this system to be very inaccurate.

I found this video a little dry.

😂

Dan BEEP sound.. damn... think ill go for the EIBOS Polyphemus

Similar temperatures like I measured. I agree, that it should go a little bit higher for PA. It can dry nylon on this temperature too, but it needs much longer drying time. I think you mentioned a link for color changing silica gel, I can't find it in your description.

I have dryers but like the dry box. It maybe worth just the dry boxes for the more hydroscopic filaments when printing. Considering it.
