The more dryer reviews I watch the more I appreciate the UI of the little Sunlu S2. There are a couple areas it could be improved and it’s weird that no one has gathered all the feedback from these reviews and made a killer product.
@@MyTechFun I just remembered I have a little 5v blower fan and some high-temperature tape. I’m going to stick it inside the lid to see if it makes a difference.
When screwing things back together always turn the screw left until it drops and then turn it right. That way you can prevent the threads from wearing out.
Nice testing methodology Igor! This is why I follow your channel. Kudos for showing the power button fix. The more people see how simple some DOA fixes can be, the fewer unnecessary returns and junked products there will be (hopefully).
@@MyTechFun Looking forward to that one. A cabinet style food dehydrator like a magic mill or nesco would be great to test as well. I currently use a magic mill cabinet dehydrator and the polymaker polydryer and like them both a lot.
I use the exact same model CNCkitchen uses and noticed it's quite a lot hotter as set on the analogue rotary knob. Also, without modifications you can't print directly from a food dehydrator.
Hey, I know a trick with screws that often even works on self-cutting screws (like those at 5:50). It as follows: first, with gentle fingers, turn the screw ('back-up the screw)' in the direction that it would go when you want to take it out. Wait until it falls into the existing track. Now you can gently start rotating the screw in the other direction. Most of the time you will find the right track with this method and it also works great on nuts and bolts and basically everything that used threads. Maybe you already knew this but I couldn't see it in your video because the part where you put the screws back in was sped up.
Great video Igor. It is great we are now seeing dryers that will heat up to 85c. I think this one seems to be cheaply made and the UI is not great. I do like the fact it comes with a vacuum pump and container though. I still like my sunlu S4 but it is not perfect but I use it way more than my Eibos.
I think you are testing these empty. They should be tested with full loads of filament because that changes the curve of input heat to heat losses. I would put the temp probe in the core of the filament to find the temp of the inner winds of the filament.
Partly I agree, but I started this type of testing with empty dryers. And using filament with unknown dryer is risky. I already tested similar dryers with too hot direct air.
I think maybe a solid, non moisture absorbant, martial/object that takes up the same space as a filament role would be the best bet. That way it factors in the volume of air and heat absorption
Great video. Do you plan in the future to try out all the new fiber filled filaments coming out? Bambu PPA-CF, Bambu PPS-CF? I would be nice to see a comparison between SirayaTech PPA-CF and Bambu PPA-CF and maybe Polymaker PA6-CF to see how one stacks up against another since the only test that was done was over a year ago.
Yes. BL PPA-CF is here (after BL PC and PA6 videos, thats in progress). Siraya will send me also their new filaments. I have no more contact with Polymaker.
Huh, I bought one of these (I think an earlier model) a while ago and this barely seems different. I bought the extension as well to allow it to hold 4 spools. I don't know if I believe the temperature claims but 4 spools is nice. The spool holders do suck though. The ones you rest the spools on are much better in terms of ease of use than having to push the metal bar in between.
@MyTechFun I do not have a filament dryer (yet). My desicant dry boxes do a great job of keeping the humidity to a constant ~10% relative humidity. I notice in your tests the RH in the filament dryer asymptotes to ~10%. Question: If I perform a one time very thorough drying of nylon in a good quality filament dryer, then immediately transfer filament to my desicant filled drybox (@ 10% constant relative humidity) and print directly from that drybox, would I ever need to dry that nylon spool again in the future if the drybox remains at 10% RH? I do not know if Nylon will absorb any considerable moisture if the surrounding RH is 10%.
Because the airvolume is very hight compared to that tiny sponge that test setup isn't very useful. 2ml is also like nothing. The sponge result will be like the same if you leave it on kitchentable for a day. Filemanet may take moisture by that!. A 1kg spool can take 100ml - to remove that is a challenge! So I suggest to use fresh spool of filemant - take weight, meake it wet, - take weight - dry and take weight again. How much of moisture has been removed?
Excellent video! However, I cant wait for the 6 dryer comparision as I bought the Space Pi(After your video). I bought some Pa6CF with my A1 to try it out but customs opened the packet with a knife in the centre😢 The Humidity here in India is around 70% right now so I need to dry it from start. Hoping for a good performance of the Space Pi🤞 After your latest video, I want to take advantage of the great filament but am scared of the 2 week drying time😅
I am glad I did not order it. It seemed like an interesting dryer at first, but I guess I will stick with my hot air fryer. I still struggle why the dryers are all so poor, honestly. My hot air fryer was like 60€ + 530€ for 3xPT100 + measuring circuit + Arduino + SSR.

Would you happen to have a link with some details (forum) or RUclips video link covering this build?
The more insides of filament dryers I see, the more stunned I am that none of them just have a look at a simple cheap food dehydrator which typically just has an AC powered heater and fan and just a simple temp-controller turning the heater on and off. Minimal BOM cost. Just change the case around that hardware with decent heat distribution and use a slightly nicer controller (with multiple temp sensors like the one in the video, but in better positions) and you have a great filament dryer. But no, instead most dryers use underpowered DC heaters that can hardly reach the advertised temperature and a fan that might be silent, because it barely blows air ...
You should test out the 3D Genius filament Dryer, it works pretty well for a single model unit, If it only had and ESP32 It would give Gratkit and Polymaker runs for their money!
@MyTechFun you might be interested to know youtube just asked me if your channel was a good recommendation the other day. I have never had them ask me that before, gave me various options for why I said yes, I chose informative and relaxing. Also, have you considered testing what might be the best filament dryer for engineering grade filaments that can also be used for annealing, the Ninja AF101 air fryer? I have one, it's great, perfectly fits a roll of filament and unlike many of them it can be set to run for hours and has very precise/stable temp regulation. They just hold a 1kg spool of filament and can be found cheaper new than anything else that will go to these temps, plus are dirt cheap and easy to find used.
Thank you for the support and a good recommendation. About the Ninja AF101 air fryer, pity that its not transparent, I could use it for my temperature tests too :-) I am planning to test a food dehydrator in near future (our own), but it's max temp is only 80C
@@MyTechFun I'm using it at the moment to dry 3dxTech ezPC-CF which so far is proving to be an absolutely amazing filament. I hope you get to test it one of these days.
I've still been extremely happy with my Gratkit Firefly which I got thanks to your review and comparison table. It does its job, although I wish it turned the filament but that can be done automatically by printing while drying. Part of me hopes Bambulab comes out with their own premium filament dryer some day!
@@rsilvers129 I did watch the video so save your snark. I thought the graph at 10:46 was for a 65°C set temperature because that’s the temperature he set (see 9:43) before talking about the vacuum storage box.

The more dryer reviews I watch the more I appreciate the UI of the little Sunlu S2. There are a couple areas it could be improved and it’s weird that no one has gathered all the feedback from these reviews and made a killer product.
S2 is a good idea, heating from two sides, but I am missing the fan in my early unit. I think later they added a fan too.
@@MyTechFun I just remembered I have a little 5v blower fan and some high-temperature tape. I’m going to stick it inside the lid to see if it makes a difference.
@@MyTechFun Yeah, Sunlu added a small fan inside, both on the S2 and the S1 - I have them. I think they are now only selling the new units with fans.

I will in very near future.

I would love to see you test some air fryers in dehydration mode. They usually can go up to 90c and are quite affordable second hand.

also, the rubber plug goes in from the inside, then you insert the ptfe tube, this prevents the filament from making the plug pop out during printing.

I have one of these. it's great...but i have had to replace the PTC heater already (less than year of use)
I use that exact dryer for when I print with PEKK
PEKK? On what printer? You print from the filament dryer directly?
I'm getting a cheap air fryer for high-temp filament drying. That'll have higher accessible temperatures and much higher airflow.
Where were the 4 temp sensors?

It does (using the print bed as dryer, it's in the settings too) :-)
What about building Your own filament dryer?
It seems to have double walls for less heat loss but still can’t get up to the set temperature
It's a bigger volume (compared to single dryer)
pls link for the vacuum box
On PrintDry website which is linked in the description.
The model in the video is PrintDry VC208
The best dryer is probably cheap air fryer.
Does it maintain 85°C throughout? What’s the temperature at the top when 100°C air is blowing out of the heater?
Watch the video. No. It got to 68C with an empty chamber. My guess is it would be lower if it had filament in it.

@@radish6691 Yeah, I was also a bit confused at first.
Man, $200US for that thing? I know it gets up to 85°C, but that is still pretty pricey for what you pulled out of the box. Not impressed at all.
