This is the first review i've seen on this thing that shows anything more than a drying test. Your talk about the specifics at the end was helpful. I think we all agree that drying filament helps with print quality but I had no idea about the hygrometer issues or the tube conflicts.
Thanks for laying this out so well, Bryan.
Learned the hard way by wasting time trying to fix why my print was turning out bad to find all the issues where fixed by drying the filament. Now I always dry the filament I am using next.
I am surprised that after 6 hours of drying, only 4gram of water was taken away! However, the result shows huge difference in printing quality too!
what an interesting product. I guess it is an obvious evolution and could be a welcome one.
It seems like a good solution for keeping those special filaments dry and at the ready. Not so much for PLA, but expensive stuff like nylon or soluble support material.
Thanks BV3D.
You're welcome, Ron! Thanks for watching!
My experience with the hygrometers has been similar. Out of 4, one never drops below 30% and the others don’t get any lower than 20%.
Great review video. I would use the orange desiccant instead, and add a more accurate sensor.
Great review Bryan, thanks
good video! thanks to share
Thanks for watching!
New subscriber here, enjoying your videos. Thank you!
Thanks for subscribing! 😀
puns not with standing, another excelent video.
I usually explain hygroscopic to my students using sugar as an exsample. How it forms clumps. just like the chicorry coffee that is made from 4 types of sugar with a dash of coffee flavour..
Keep the blue stuff outside your body and avoid skin contact and you're fine...oh, and also when it's pink.
The dryer presents itself more like a prototype than a finished product. Still, seemingly a competent product
What is the hottest temperature it can achieve? I feel like most of these don't get hot enough to really drive the moisture out of mylon.
0.3% cobalt in those beads is only going to be a problem if you actually eat quite a lot of it. Even then your biggest problem is probably going to be that you're eating a ton of silica. I don't see any cause for concern and this type of silica is used in industry all the time with no required precaution or OSHA concern.
I was dying a solution like this a year ago. And mine used a silicone door that opened automatically with pressure rather than manually popping it open. But my enclosures kept melting as it was PLA and I couldn’t print ABS back then, maybe I could revisit. I even wanted to put rfid tags for material type so the temperate is automatic
Almost there... a few tweaks... revision "next", and it could be just about ideal.
Great review!
Love the shirt
Haha! Thanks!
Thanks for the thorough review. I wish the storage boxes were cheaper, especially given the issues with the hygrometer and blue desicant. I could see myself wanting perhaps a total of 4 of the storage modules, which is getting up to the level of "real money".
Good review. I just received mine from TH3D, it seems I was lucky, as now they are out of stock every where. I had my own dryer that I made from a food dehydrator, but this looks like a great solution and seems to be a fair price.
Very nice! I just found out that Polymaker has some printable accessories for the PolyDryer up on Printables. There's a wall mount and a couple of Air Lock holders available.
I suspect the health and safety issues of the cobalt in the silica gel is far less than, you know, the ABS fumes we all inhaled last decade. Kind of strange that there is a "safe" alternative that they didn't go with; I wonder why.
Hygrometers are a nightmare from experience. I usually put them in a seal container with water and salt to try and get an idea of how accurate they are, they should cap at 75% after like 24 hours … in reality most are off by 5-15%.
I agree with your comments about the Cons. I live in Houston and stuck printing out of my garage in +/- 80% RH most of the year. Even my PLA will go bad in a week given how bad it is. But, I use the clear plastic cereal dry boxes and print out rollers and desiccant holders and they work just fine to print out of. Somehow, I never thought to have a unit like this Polymaker drydock. Maybe we could tear down our older, less useful, Sunlu S1 units and make a drydock for our own dryboxes. Hmm. Maybe we will.
As for the blue desiccant, I'm sure if you don't eat it and don't breath its dust in when refilling or shaking, then it should do ok. Is the blue silica gel removeable from the dry boxes? Is that also where we recharge them, by using the dry dock?
Thanks for sharing!
👍👍👍
I love polymakers glass fiber nylon filament! Though I'm having a hard time finding a dry box solution that fits the 2kg rolls. Does this fit those size rolls?
No. Polydryer is for max D205x78 mm. For 2kg spools maybe check Eibos Cyclopes or Polyphemus, Fixdry or Sovol dryers.
I'm with @MyTechFun on the Eibos Polyphemus. It'll hold up to a 3kg spool, though that requires printing a little riser to raise the top up a bit. Eibos has the printable file available for free.
Great video BV! I think you need a T-shirt battle with Lisa Gade at Mobile Tech Review hehe
May the 4th be with you too.
😉
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?
The price is a bit steep. Yes, even the spare boxes. Sure, the single spool storage boxes on Amazon are higher price, but frankly you have to dig through the search results to actually find them - which tells me they're not really selling at those prices. Most people are probably buying things like actual cereal boxes or other generic containers for filament storage, rather than storage specific to filament. It's the dryers most people are buying, and most dryers are in the $55 USD range.
Great video but how many "drying cycles" do you run a spool through? I know it all depends on the humidity in the air but would you consider maybe 1 or 2 times ok? Or maybe 3 times? Where I'm at the humidity hovers between 45%-55%
I ran the spool through a second 6-hour cycle, but I didn't see any further improvements. But running PLA through a 12-hour drying cycle shouldn't hurt anything. You can try it on one spool, see how it does after one cycle, then dry it again and see if it improves even more. If it does, then maybe try a third cycle. But if one cycle seems to do it for you, you can probably just stick with that as a baseline, and run the filament through a second time if it looks like it needs it.
As a side note, I _usually_ keep my filament in gallon zipper bags from the grocery store, with a desiccant pouch, and that seems to keep it happy most of the time. The RH% here is at about 53% at the moment. :)
@@BV3D Thanks for the info. I also keep mine in zipper bags with a few desiccant pouches. But never really know how well they work. I have old filament (3-4yrs old) that are also in bags with desiccants. Hopefully they can be revived by drying them out.
The blue indicating gel is illegal in some countries. I think it's actually banned in the EU, if I remember correctly.
Is it possible one is measuring relative humidity and the other is actual humidity?
I don't think so. But, as a result of your question, I learned that while relative humidity is expressed as a percentage, absolute humidity is typically expressed in grams per cubic meter or kilograms per cubic meter.
Ngl, if they lost the hygrometer in the boxes and dropped the price to around $15 each, I might grab a few
What a surprise that the Polymaker PolyDryer is pricey and the extra boxes are too! That's why I don't buy their filaments because they are the more pricey premium type of filaments.
I know that lots of youtube 3D printer channels bang on about how great the polymaker filaments are? But that's because they have them for free under a sponsor set up!
I stick to my Sun Lu 4 spool dryer as it is great. and now that I am only going to have 3 printers instead of the 5 I have at this time due to 3 of them mucking me around too much and not working even after the costly upgrading I've done to them, I be fine with using my 4 spool dryer and the 2 single sun lu S1 dryers I had before I got the 4 spool version.
I do like running their filament and haven't really gotten any better, but it's not enough better to justify the price for me either. My Sunlu S4 has been great as well. Seems like Polymaker is following the "send out an unfinished product" trend like most 3D printing companies...
Nice review. About silica gel, I am not sure, but if it passed rigorous EU regulations, it should be safe. How do you like beep sounds? Mine is too noisy. My hygrometers are more accurate, they don't jump and similar values in two boxes.
The initial power-on beep is OK, but I think the five or six beeps at the end of a drying cycle is a bit excessive. I think three beeps would've been sufficient. I'm glad the hygrometers you have with yours are working correctly. Mine may have come from a bad batch.
I am not a fan of the cheap hydrometer at this price point, especially if they are getting damaged from the long exposure to high temps of the heater.
One other concern that no one has mentioned, does the drier vent out? It looks like it just circulates the air. That released moisture needs to go somewhere or it will get absorbed by the filament again once its cooled.
He mentions this @ 8:20. Yes it has air exchange through vents on the side of the dock.
It's got some nice concepts, but like you mentioned, it's not exactly perfect.. Would definitely be more enticing if the price of just a box by itself was less as well..
Before an after look meh. Very similar except the small area you observe near the antlers. I see lines not consistent. On UA-cam I see videos that are prob click bait that show lines vs Matt smooth finish
What’s it take to go from messy lines like you show(sorry to exaggerate) to a perfect finish. Is this just acetone smoothing or a slower function to make a smoother finish. Love some feedback and also sent you a dm on twitter. I’ll buy a coffee to get some good advice if you ask.
Thanks for all the videos.
The idea is nice, but the execution seems lacking ... Instead of having to plug the bottom yourself when removing the box from the dryer, I would expect a spring-loaded mechanism that has the dryer poke into the box to inject its heat. That way the moment you remove the box from the dryer, it automatically seals again. The boxes themselves should also be much cheaper. Definately < $20 per box, < $15 would be even more logical. The hygrometer can be left out or offered as an accessory, if that is contributing to the cost of the box. Same goes for the dessicant. Now, I'm certain China is watching and will clone this good idea and since Polymaker's implementation makes it so easy, I guess we'll see better and cheaper implementations of the same idea appearing from Chinese brands.
You do know we are a Chinese brand :)
@@Polymaker :-) Actually, I did not, but was not really excluding it. Doesn't change my statements though that the boxes are too expensive for a concept whose selling point is to lower the total cost by splitting off the "expensive" part. Then the "cheap" part should cost less than an Ikea 356+ box.
blue gel----life is bad for your health
😀
Seems like Polymaker is following the other manufacturers in the "send out an unfinished product" trend... Would be nice if they would stop expecting us to be the beta testers and if people would stop pre-ordering and buying unfinished products. Real shame.
It is not an unfinished product :)
kind of a stupid solution if I might say.
Hi, what aspect of it do you dislike?
@@BV3D There is nothing special about it! It fails at uniform heating of the material; it should rotate while drying but doesn’t. What's the point of having a humidity indicator when it has no calibration. Is it there for show? Functionally this is very similar to the EIBOS Polyphemus, it has a chamber and a heating element. The chambers sit of the heating element. EIBOS vents to the top, the Polydryer to the bottom. EiBos rotates the PolyDryer doesn’t The PolyDryer chamber has to many parts. A single spool chamber is kind of silly why allocate x hours of electricity to dry ONE spool.
It's kind of absurd the box you store your filament in cost more than the filament itself (majority of the time) Anyone that has a printer knows you end up with dozens of rolls of filament. It quickly becomes a logistic nightmare. With that in mind, the cost to store needs a solution. PolyDryer failed at it!
Manufacturers vacuum pack their products and include a small desiccant. I believe this is the least costly method of storing filament.
My approach is to use a Vac100 Chamber Vacuum and 12” x 14” 5 mil bags. These bags are multi-layer with moisture and air barriers. The ones I use cost about 20 cents each. For the desiccant, I purchased “loose leaf Tea bags” from Amazon, put a tablespoon of desiccant in and tie the draw string. Everything is then placed in the vacuum chamber for about 8 seconds. It vacates the majority of the air and seals the bag. Don’t pull a full vacuum because you will crush the spool.
These chambers are expensive and are primarily sold to preserve food. They work perfect for sealing the filaments. I like my stuff to have dual purpose. The saving in food more than justifies the cost. Storing your filament cheaply is a bonus.
@@BV3D I responded to you a few days ago.... what happened to it? Did you delete it.
@@judd_s5643 I didn't delete it. If you don't mind reposting it, I would still like to know. Thanks!
Looks like a nice system, except the hygrometers :( Hope they replace them with something better. Not too pricey considering other options or having tot have 8 dryer box with cords plugged in compared to just one with 7 boxes keeping the filament dry! Oh I forgot - the blue silica beads, makes no difference to me. Everything now a days will kill you or give you some sort of cancer so a few grams of silica compared to the millions of vehicles/factories/etc doesn't really bother me.
