Thank you BV3D.
Nice review. Is the bubbles just a removable screen protector for production / shipping? Looks removable.
Came here to say this :D
I really like the Eibos Cyclopes two spool (or one bigger spool) dryer and keep it between two of the printers I use with TPU a lot. The lack of rotating was something that caused color changes in one spool so I made sure to do shorter drying times or spin the spools around like you mentioned you've done. This looks like a great improvement with the rotisserie option (totally should have been the name). The only other thing I dislike about it is still present in the new model and that's if you're printing from both sides, or even one side and what to change the other spool. Getting the hat off while filament is pathed through one of the apertures involves a balancing act holding the lid up, playing out excess filament for the spool still in use so you can remove the second spool. Then you need to get the other spool in and thread the filament through the hole you want so you can put the top back down and keep printing. I don’t think I’ve successfully pulled off the swap without knocking over the other spool, making the process quite frustrating. I was hoping for a front panel of the “hat” that was hinged so one spool could be swapped without disturbing the currently printing spool. Other than that one issue, it's a great dryer and one I go to regularly.
Great video, love the visual of the two grams of water loss!
A great and very fair review. I am in need of a new dryer as my Sunlu has died after a couple of years continuous usage. I'm not sure I need something this big but it is a consideration.
The new S2's have fans. I've been using one for a while now and they work acceptably. Certainly not as fancy as this one. Most of them are sort of accurate but not precision devices. They all mostly work.
Awesome review! I have the Sunlu S1 and for me, it's worked great. I think one of the things I could see for this dryer is using 2 printers and having this sit in the middle and have one spool out the front and the other out the back. Great job Bryan!
Parking this between a pair of printers? That's a pretty good idea! 👍🏻
Excellent video as always, I use the Sovol Filament dryer and a Comgrow one as well. both take 2 x 1kg spools and they work really well.
so would you recommend the Sovol dryer ? I have been using a Sunlu S2 dryer that recently expired after 2 years of continuous use.
@@TsiolkovskySportingLocks Yes, I would totally recommend both dryers, both have fans for air cycling and are priced really well.
Polyphemus arrived last week, I did some testing comparing to my Cyclopes dryer.
First impression: It's silent! The cyclopes fan is somewhat noisy, I don't her the Polyphemus in my office. If it is completely silent i can hear it but the rotation motor makes more - faint - noises then the fan. Well done, Eibos.
The Cyclopes heated the table under the dryer, at last I put a metal socket under the dryer.... that's gone with the Polyphemus.
Temperature: The Cyclopes promised 70°C but the one i have here reached aboout 60°C max. Temperature distribution was bad, on the bottom beneath the spools 50°C but above the spools sometimes less then 40°C.
The Polyphemus has much lower differences. Display 50°C, chamber between 45°C above spools and 48°C beneath spools. Nearly perfect. Couldn't test max temperature as I lack testing filament spools for that.
So all together well made and worth the money.
I've only one point to complain: The motor driving the spools has a lifetime of 1500 hours. Really, Eibos? The default for PLA is set to 4 hours, that's somewhat .. optimistic even for PLA. Other filaments take up much more time to dry, 10 to 12 hours. with 10 hours we have 150 drying processes until the motors livespan ends.
Everyone flexing their polyphemus on youtube. I got in on the preorder. Eibos isnt shipping them till mid december.
Watch your language, young man! haha j/k
I use the Eibos Cyclops and the Sovol dryer. The Eibos doesn't have the rotation and there are reports of damaging the filament on a full spool. I use it with a printed part that creates more distance between the heating element and the spool. The Sovol is handy as a drybox for printing, but it isn't powerful. Drying PETG takes a lot of time, while 65 degrees Celsius is required, while only 50 degrees is available
My problem with most of these dryers is that they use a couple spindles at the bottom and the spool rests on them. Printing while drying, even plastic spools can run pretty rough, and this can affect print quality. Some cardboard spools don't work at all. A dryer that holds spools at the center would be a much better design.
Hey Bryan, The bubbles you referred to in the screen... are you sure that isn't a protective film from the factory to prevent damage to the screen?
I'm not 100% sure, because if it is, it's on the screen, and behind the clear window on the sticker. I can't tell without taking the unit apart and getting to the screen from the inside.
Just ordered it.
The Polyphemus avoids the problem of the Cyclopes. The Cylopes works quite well - when printing. When drying two problems may occur: The temperature at the bottom is good for drying - then it is too low at the top and ilament will not dry. I've measured differences between top and bottom inside of 15°C and more.
Or temperature at the top is OK, then the filament melts at the bottom.
Rotation is a nice way to avoid that.
You can mod the Cyclopse ;) Check out printables. The user "warpster" /model/336958-eibos-cyclops-drive-mechanism has a mod for it. I use this mod for a long time.
@@H1zN I know and I did that.
But I think it can't be a customers task to make a paid product usable. The Cyclopes wasn't that cheap..
Did it hit 70°C and manage to maintain it at a constant? I have the 3d Genius dryer and it struggles to keep that high of a temp.
Those extra features should be dead-simple for the factory to add. Wonder if they used arduino code or something proprietary. A NodeMCU could easily handle all the functions and then some.
Nice video. My question is where oes the water / moisture go? A typical dehumidifier has a catch can. Is it just the fact that the two cubic centimeters of water simply evaporate? Thanks
Hi. Yeah, a dehumidifier works by chilling air to condense moisture out of it, so it needs the reservoir to hold that water. Then you have to empty it all the time. A dehydrator works more like blow drying your hair. It heats the air, and the warm air can hold a lot more moisture than cold air. So yes, basically, that 2cc of water evaporated.
The one issue is the rollers lacking grip, and I will be trying PlastiDip on them to add grip. It's temperature resistant up to 200F/93C so it should be perfect for that application.
have you ever try to dry PLA Meta? I am worry that the 50c are too much for it
I do like this design, but you may want to check your original Eibos drier as I’ve found they made a mistake on the front dial with the temps. It’s supposed to show PLA, PETG then ABS & TPU, but on the early models they made a mistake on the label and switched TPU & PETG but didn’t tell anyone about the mistake.
Would be intresting to compare energyconsumption. Spending 10 bucks on my electricity bill to have a 20 buck filament spool print a tad better seems uneconomic.
Thanks for introducing this product, I think it has potential but I don’t think it is a good design. Why not just put their STL online at one of the many 3d models sites? Good to see they include a spare motor, I didn’t hear you mention a fan, they say it has a “silent fan”. Maybe heating one side is a good way to dry out that section, then move on to the next. Notice that if the motor turns the spool a but then stops, say 20% duty cycle, it will last 5 times longer. They missed one significant aspect, thermal insulation. The heat losses are enormous in their design so you need much more energy to reach higher temperatures and so more local heating of the spool and the parts in that area. For you own design, I use a cheap timer to set the on time, of course you have to realize that it repeats every day (I used a Christmas lights timer, $3).
This is literally a system that heats the filament at the bottom the turns it a bit. Without thermal insulation the top will be cooler than the bottom. With air circulation and good insulation the spool turning is unnecessary.
Having the rollers slippery, might be good for allowing spools to rotate while printing, whilst having rotary mode on?
I forgot to mention that the manual says, "Don't run it in spin mode while printing." When the motor isn't engaged, the rollers spin freely.
@@BV3D the rolls are linked through? So if you are printing and have a second spool just drying, it will get rotated around by the movement of the printing spool?
@@liamtwentyman7275 The powered rollers are independent from one another. Spinning the rollers on one side doesn't spin the one on the other.
@@BV3D can you choose to just have one side powered then? Or is it both sides or nothing?
@@liamtwentyman7275 It's both or nothing.
Excellent review as usual. But not quite enough puns this time. I'm really wary of any Eibos dryer, since my 13-month old Easydry, purchased after I saw your review of it, stopped drying this week. The fan runs, but no heat. It was used only once or twice a month in those 13 months, so I can't endorse any Eibos product now based only on initial quality and performance.
I'm on preorder for it (zone 2 - USA). My order was placed this month, probably I'll get it in February. Unsure really.
send it back when u get it. it's trash.
@@user-ob5ss8xk1b Please give me some details why it is trash. Presumably i could still cancel since it hasn't shipped yet.
*Or better, upload a video showing the issues. Thanks!
just read my comment...
i'm not going to upload that stuff , believe me or get one and hope it works out for you@@BennyTygohome
I’m still up in the air if a dedicated filament dryer or food dehydrator to “ dry” my filament
I've noticed PLA is worse than PLA+/2/pro for going brittle. I have PLA+ that's been open over a year (sad, I know) and still prints same as day 1. The PLA (marble) gets brittle quick for the 1st foot or so.
seems to me that all those dryers should've had all those features from the beginning. 3d printing companies trying to shaft us on the manufacturing end, making us buy 3 half featured dryers and then enticing us with an expensive unit that finally does it right.
How do I get a BV3D sticker?
Price went up $15 compared to your screenshot since you made this video... which is weird considering this is all in their 'black friday / cyber monday' time period. Bet they saw an increase in sales and decided to increase profits per piece as well.
allready have bad alligned threaded inserts , socket loose on the body of the machine , motor that came with it burned after 5min of operating , powered rollers slip on the orings , and so on... i'm sending it back sucks after 2months+ of waiting for this.
Is that just a screen protector?
It looks like a protective film, but if it is, it's on the LCD screen itself, not on the black sticker with the clear window. I'd have to take the unit apart to be sure. If I remove the black sticker, I may not be able to reattach it again (you know how stickers get!)
@@BV3D Check out Modbot's review of the same dryer at 3:07. Spoiler alert: he peels off the protective label.
@@yeroca So did I, but the bubbles on mine are _underneath_ the black label. 😁
@@BV3D Maybe you can peel off both, and then reapply just the black label.
@@yeroca Sadly, those never look the same after you do that. If it bugs me enough, I'll take the bottom panel off and go in from underneath, to get directly to the screen and see if it still has its manufacturer's protective peel on it.
and "wheel" find out. i see what you did there
😉
11:20 I would really say you simply forgot to remove the peel.... Not only how it looks on the screen, also between the buttons.
Yeah, that's what it looks like, but I peeled the peel that was on it. It's POSSIBLE there's a protective peel on the screen itself, _behind_ the sticker, but I haven't taken the unit apart to see if that's the case.
2 grams of moisture reduction for 12 hours electricity?!? Not impressed.
That's about as good as it gets. Thanks for your comment, Chef!
Differently not for the hobbyist @ $1000.00+
Not sure where you're seeing it for $1k but the Polyphemus filament dryer is $129.99 on the Eibos web site.

TO EXPENSIVE... WHAT A JOKE
The one issue is the rollers lacking grip, and I will be trying PlastiDip on them to add grip. It's temperature resistant up to 200F/93C so it should be perfect for that application.
