Compact Filament Drying & Storage System (Polymaker PolyDryer)

[@Liberty4Ever]

It's very cool that the product page has acknowledgements for community members who helped design and test the PolyDryer. That's a welcome change to most companies that have staunch objections to Not Invented Here. That's probably why the PolyDryer is such a well designed, clever, user focused solution.

[@chrisl4999]

3:14 Thank you for pointing out how the ptfe tube connects. I've been trying to find out if the tube actually fits through those holes or not and so far you were the only one to point it out. Even their directions kind of ignore the tube other than to say there is one. 3:58 The desiccant that came with mine was orange. The instructions say that it turns from orange to dark green.

[@rynnjacobs8601]

At 6:40 one can clearly seen, that it was assembled incorrectly and the fan-wires were pinched.

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.

[@ModBotArmy]

Thank you for the reminder! I feel like there is always something I forget. Link has been added to the description :)

Fantastic video. I've been watching a nunber of videos on this product as they've rolled out in thenlast couple days. Yours is by far the most detailed and thorough. Great job!

[@ModBotArmy]

Thank you! I really tried to be as thorough as possible.

[@adroitredtiger]

[@AidenG-w9z]

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!

[@TheFishTankChannel]

The PET--G setting will deform bambu spools and melt the pet-g filament strands to one another resulting in a 100% wasted spool of pet-g. it did not seem to deform the high temp spool on TPU but i havent used enough of it to find out if the tpu filament is damaged like pet-g was. all the pet-g with in 50mm of the card board center fused when set on power level 2 for 6 hours for pet-g. use with care it will cook filaments on power level 2 or 3.

[@Reedith]

Dang didn't think it was that strong do you think maybe you got a defective unit? I've let mine sit for pretty long and no fusion yet

[@TheFishTankChannel]

@@Reedith i am beginning to think it is the heater that is miss behaving. The last roll of TPU was fine on a bambu high temp spool. It baked another spool of bambu petg on the factory bambu spool. The spool face near the heat exhaust is deformed and sagging on a 6 hour dry cycle and the filament semi fused for a spot about the size of a silver dollar. The resulting petg can be separated but it is highly brittle and cant feed through AMS. For my self i am drying all petg on heat level 1 for now on. heat 1 hasn't melted or deformed any bambu spools of pla yet.

[@aipengineering7519]

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).

[@justinchamberlin4195]

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.

[@Daniel-hi8wc]

I appreciate the thoughtful temperature measurements (and cross-checking between different instruments), which is something similar reviews and reviewers do not do. Sub'd!

[@Kenprints]

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?

[@TheTurbinator]

Holy FUCK, you are a GENIUS !!

[@Bacender]

PolyDryer seems really nice but the basic unit (box and dryer) is $180 in Australia (approx US$120) which makes it obscenely expensive in comparison to things like the Sovol dual spool dryer boxes. Hoping the price comes down to a more reasonable level soon.

[@jonathanrogers9961]

I just put mine in a medium storage tote, with a 750g silica gel container. I can fit about 6 spools and 1 silica gel container per tote.

[@rynnjacobs8601]

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

[@samk2407]

I mean it's more expensive than other dryer units but I can tell you that the filament dryer is got from Ebois that's like the first Amazon one and a bunch of people have it is actual trash so I'm willing to get one that doesn't melt my spools (which that one did) and fall apart completely after a few months of use.

[@WillPower311]

[@kentkacs3140]

I came across this system and am interested in it. This video was very helpful, thank you!

[@pcvanvliet]

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?

[@TorianTammas]

These hygrometers are known for "tolerances" as in all over the place

[@impetus444]

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"

[@CarlYota]

Yeah if done right it should be a mod with no collateral damage if you’re willing to open the device (not sure how hard that is on this dryer.

[@davisdiercks]

Same here, and that was my exact thought when he mentioned it

[@fredlshea]

Great review. Thank you. Helped very much in determining to purchase the product.

[@ivyr336]

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.

[@extrutim]

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.

[@SSoaker]

[@deecat2018]

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

[@brucemilyko8549]

There is a mod for the Bambu AMS called Python. The enclosure for this mod will accommodate up to 4 PolyDryer units (The maker says that most people won't need more than 2). That will accommodate multiple size spools and can hold up to 4 spools at a time. I am printing the parts for it now.

[@LisaHarsh]

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

[@ModBotArmy]

Yeah I could see some that already have dryers just adapting the dry box system for storage. At least as a starting point.

[@coledavidson5630]

Does the hygrometer stay on permanently once you pull the tab? That seems a little inconvenient as far as burning through battery

[@dc345601]

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.

[@MattBieniek]

I feel the same way. I contacted polymaker and actually got a free replacement base and still feel like the air flow is lacking. Also can't get the moisture level below 35 while running.

[@barrya5473]

I have a question about drying: How long would it take to dry 4 feet of 1.75mm diameter filament being printed at 500mm/s? I feed my printers from ceiling racks with many items hanging above. My printer table (V400 tall) is on wheels, allowing me to move it as needed. I've designed special rollers and holders for this setup. Regarding drying, why can't we use a long, heated, and vented tube, say 4 feet in length, to dry 1.75mm filament at a speed of 500mm/s as it feeds into the machine? This could eliminate the need for filament boxes and extensive drying times. Only the necessary amount would be dried on demand. While I'm not an expert, I dislike the idea of using a special climate control device every time I change filaments. Please educate me. I can't be the 1st to think of this?🤔

[@bertkooijmans4769]

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.

[@Envinite]

More expensive hygrometer does not even matter for this application. This is just a box that keeps plastic dry, not some lab-application that requires highly accurate reading. If only they sell the box at lower price though, but I can understand why it is priced that high. I have one and the quality is solid unlike the DIY cereal box stuff.

[@T3chWarri0r]

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.

[@hakaiyou4532]

I just order these 2 dryers + 2 dry boxes for 120 bucks which seems to be a good price. But, lets see if it good or not.

[@soggynode]

$30 for the box is pretty reasonable. I did the DYI cereal box a few years ago and by the time I got the box, roller, hygrometer and desiccant I was $25 into it and it didn't even seal all that well.

[@justinbaits7149]

I made 6 for a total of $60. Even accounting for time it is still a much better option than $30 each. Mine also seal fine and hold around 10% humidity.

[@soggynode]

@@justinbaits7149 Dang, I should have got your shopping list. The rubbermaid box alone was $10 on amazon back when I got mine. Probably would have helped keep the cost down if I'd been building more than one.

[@Frankie_Freedom]

Got more info on that? ​@@justinbaits7149what did you use?

[@timtoxopeus]

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?

[@MrWheezyE420]

@timtoxopeus The lid works both ways, so if you need the grommet on the back just flip the lid around and clip it that way.

[@karlschuneman7960]

Maybe add a new video on how you recharge the desiccant. not using a microwave or oven.

[@michaelgleason4791]

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

[@A1N0]

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.

[@bigcheesetxmedia]

thanks. will buy a combo on black friday

[@ezekielgml]

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

[@fharni]

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

[@highroyds]

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

[@squeemeister]

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...

[@speakoid]

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.

[@kylek29]

Yes, I have my filament in cereal boxes and looked at creating an adapter for the bottom .. I tried to get a Polydryer over the weekend to make it but they're on backorder. Truthfully, the dryer portion itself isn't that difficult, one could get a hairdryer (or another controllable heater source), Arduino, and spend a day writing some rudimentary code to create a very similar "adapted" product using the cereal boxes sealed lift gate.

[@joannechan8478]

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?

[@TheToonamiRevolution]

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.

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

[@elleryfg7853]

I also think the S4 is more polished well rounded product. That being said a system like this gives you flexibility since each filament has it's own dedicated chamber. You can dry nylon, PLA and any other material with just one drying unit and separate drying boxes. The S4 doesn't have that capability.

[@jamescassidy2098]

@elleryfg7853 True enough, if you need multiple dryers for different fillements, even the single sunlu filament dryers are much more compact better and cheaper. although I haven't used one before, so I can't comment on performance, but I can't see it being bad.

[@AWZ1287]

The sunlu looks like a good option if you need to run multiple rolls at the same time. But if you are just running one roll at a time, you can get the combo + 4 spare boxes for 200 and be able to store a total of 5 rolls.

[@billmacfarlane4083]

Not hot enough...CF Nylon mixes are becoming more popular and really need to be dried before use. Some requiring 130 C. These temps would probably be beyond the cabability of the materials these are made of...ie they would melt.

Idk if it's the same one, but I use something called the filament bunker. It's basically the same design as the poly box (chamber for dessicant and a hygrometer) made out of a cereal box. There's mods on printables for adding a PTFE tube coupler.

[@Sevensup]

It's $90 now for the complete box.

[@judd_s5643]

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.

[@popfizzle3908]

If you want a dryer for low temperature, then the Poly dryer is good. I sent mine back because the highest dry temperature only got to130 degrees F. ok for PLA but not much else. Love the concept but lacking in higher drying temps is a no go for me. I need a dryer that'll do at least 175 degrees F. Oh! and a humidity meter lodged inside the desiccant holder does not give an accurate humidity level inside the box.

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.
