But he didn't have a control group... You can lose moisture over x amount of time just from evaporation. I think he should have left a sponge out of dryers and compare his results. That way we not only know how well the dryer compares to each other, but just the effectiveness of the drier themselves. A solid test and thorough test regardless
I think there may be a significant difference in which can evaporate the most water in liquid form, and which one can maintain the driest air to allow moisture to diffuse out of the filament.
As a non-engineer, i like this too. However, placing them one next to the other, will make the outer ones underperform, as the middle ones share heat. Same goes on in the appartment building i used to live in. If the neighbours turned on the heat, i could notice it.
You need way more views on these. It’s rare to find a non biased tester these days. Can’t thank you enough for all the help you’ve given me personally.
People are reporting that the EIBOS is so aggressive that it eventually melts the filament at heater fan input at the bottom. It might do well with a deflector of some sort so that the hot air isn't blowing directly on the filament. Similar complaints with single roll EIBOS at the center of the spool.
Thanks for all your work Igor. I use a PrintDry Pro. It is noisy but blows a lot of air and holds the temperature accurately. It sucks outside air, heats it, and blows it through the chamber. I have found it works great for me. I had a fan motor failure after one year but PrintDry immediately sent me a new base free of charge. Pretty awesome customer support. I took the old one apart and found the fan/motor construction to be of low quality. A very simple redesign of the fan and ducting would make this much much quieter. Keep up the great work, Igor.
Thanks for the video! By the way, the Sovol manual says to leave the lid cracked open and I think this would improve the performance a lot as it will allow for the humidity to escape.
Exactly - it is a dead giveaway that the humidity drops when the lid is opened (at 12:55). The Eibos has vent holes in the lid to provide this venting, while the other dry boxes should be left slightly open while drying. The Sovol, as you mention, even has hinges which will provide the correct opening while drying.
This is EXACTLY what I have been wanting to see for a long time, a comparison between these in a good way, it is clearly that even that I got the sunlu dryer extremely cheap, it still feels like a bit of a waste and explains a lot of why I have not got any good results from it Especially right now in the autumn here in Sweden, right now my humidity is around 70% in the air, inside with no windows open, that effects the filament in a pretty negative way I will wait and see what the new upcoming ones you talk about will bring and if they are better! Thanks for this video, really interesting to watch!
Nice to see a comparison like this. Just a suggestion, as location of sponge vs heating elements can be critical, use an empty spool and put the sponge in the middle to allow for that. Also having them next to each other means the ones in the middle get more heat (from the other dryers) than the ones on the end - test one at a time or space them out more (though spacing out more you risk having diffenent background temps in the room. Cheers.
Loved your very objective way of measuring and being able to compare the performance of the dryers. It was exactly what I was looking for, and this approach is very different from all the other reviewers of filament dryers. Kudos! Just as a suggestion, I always like the approach of being objective first, then subjective - I noticed you didn't want to give your opinion and let the data speak for itself. But I think once you've collected the data and presented it, it's also very valuable to then provide your subjective opinions - e.g. which dryer you feel is the best value for money, etc etc. When you do more of that, people will learn to appreciate your opinions as being reliable and data-driven, which is always a good thing! :-D
I really wish I would have had a review like this a year ago... I would have bought the eibos instead of getting the sunlu and the esun. Amazing work as always, thank you!
Add a fan (many RUclips videos explaining how) and keep the lid open a hair. That turns your Sunlu filament heater into a filament dryer. There is a good reason why both food dehydrators and clothes dryers both expell a lot of hot, humid air...
Awesome test! A lot of new filaments have launched since the making on this video, so please consider doing the test with those! I am sure companies would be glad to send them for you to test. I wold love to see the new Sunlu S2 with the 360 heater, FixDry dryers, Comgrow, etc.
@@MyTechFun awesome. I indeed found you already had reviewed those models too. I have always used a Sunlu V1 and I am looking to upgrade. Your videos have been incredibly useful and you have saved me time and money. Cheers!
You're te hero we don't deserve but we need. I wasn't aware that I need dryer for PET-G and is best to keep filament in the dryer during printing to achieve best results. Thank you mate
About PETG, my method in most cases: I take it from the bag (when it is new), do the printing and when finished, placing back to resealable or vacuum bag. In this case you can avoid using the filament dryer (but the best if you do use it even for printing) Nylon: Similar to PETG, only even the 3D printing is done from the filament dryer.
Wish I had seen this 4 months ago! I didn't see any good reviews for dedicated filament dryers back then, so I bought something bigger than I really needed. The facts: I bought an Ivation food dehydrator from Home Depot, drilled holes in the side, installed Bowden tubing to act as feeders. Its big, its noisy, it heats up the room, but it can dry 4 rolls at once! 5 if you don't mind crowding. Highest temperature is 158F/70C, lowest is 96F/35C. Regulation is quite good. Timer runs up to 10 hours. The fan inside is ferocious, lots of swirling air. Does a decent job of annealing PLA objects. Two rolls printing, two waiting their turn. I live in Seattle where the humidity is constant; Lakes, rivers, Puget sound...we are surrounded by water!
Sovol recommends running theirs with the lid cracked open. In this sense, the unit was not used per the instructions. Running with the lid open, however, would likely slow the initial warmup time further and may allow the surrounding environment temperature to influence the maximum achievable temperature inside. I think the lid's sealed nature is also aimed at using it as longer term dry storage when the dryer is off. The clips are designed such that the lid can stand ajar on them while running as an active dryer and this allows the humidity to escape. Still, performance may be slow. Also, I note from my own use that the Sovol dryer gives off some heat to its surroundings and as such perhaps the test should be run with the dryers spaced further apart to ensure no interaction between them. I do like the idea of the test though. Setting all to the same temperature target might be more useful for comparison unless the point was that a superior range of temperature can be beneficial (assuming you stay below glass transition temps).
If we were to run them lid open, I wonder if the environment air (which can be humid) can run in and prevent the moisture to be fully exhausted? Apparnently it's not like a single-way air exchange that prevents humid air from directly going in?
I love this video! The way to show the results and how the experiments were made is awesome! this types of videos are the one that need to exist on the internet, this videos help everyone to know the truth about how the products thae we want to buy works and how the companies are spending their time to create good products (or bad products) for us. Thank you very much for sharing!
I have the Eibos. It works very good. I would not suggest running it for a 24 hour print, because it can over dry PLA. For PLA just run it once at 50C for 4 hours, then just use it as a spool holder for the print within the enclosure.
Excellent video. I've been in the market for a dryer for a while, and was about to simply make my own. I am neck deep in projects, and I'd rather just buy a dryer, than divert energy away from other stuff. One thing, you forgot to include a control. You need to put a sponge on your thingy so you can measure the rate at which it dries in ambient conditions. You need this control for your drying rate. No control means you only have absolute values to work with. Final water content is an absolute value (and in this case the most important one), drying rate is a relative value, and needs to be compared to a control.
Your channel really stands out in the way that I can feel you have the constant hunger for improvement and knowledge. I really hope you get many more subscribers. Is there a way to get the excel with the temperature/relative humidity over time available somewhere?
nice video, I have the Eibos for PETG only, I find the heat release enormous in the office, fan noise less loud than the ender 3v2. Remove the black "humidity" label on the humidity sensor of the Eibos, we will also have the temperature in the box in ° F or ° C. 👍
I just got one of these dryers about a month ago, and I was expecting to have to remove the "humidity" label from it to see the temperature, but it shipped without it, so I didn't need to. It makes me wonder why it was ever on there.
Thank you for this video, I have a Sunlu one, but I added fan to it and some circuitry for the fan to be only on when the screen is on and moved the thermal probe up so it really heats up.
same here, saw another guy make a video on it. added a silica gel container inside the spool as well. hopefully its just as or more effective than the others now
Same here. Would be great to see a modded Sunlu in this test as well.! Definitely its increasing the performance but wondering if it is comparable to the others.
@@tanujak98 Yeah, I took that video as an inspiration, but went further. Added a relay controlled by a octocoupler hooked up to one of the backlight LEDs, so now when the timer on the dryer runs out and the screen switches off, the fan switches off as well
I own a Sunlu dryier and was indeed not impressed by its drying performance. I did very similar to you with the humidity and temperature sensor inside and found out that 2 10mm holes, one in the bottom below the heater element and one in the top greatly improved the performance. Humidity inside the box dropped from around 55% to 15% in half and hour. The temperature inside the box was actually higher (don't remember the exact number but about 5 °C) with the holes versus without. Drilling 2 more 10 mm holes did not help any more. So I ended up with 2 10 mm holes one in the bottom and one in the top on opposite sides to improve the design.
I along with others would really like to see a food dehydrator compared to these dryers. The only reason I ask is because the Rosewill Dehydrator looks like an affordable solution compared to the Eibos.
Super test. But wouldn't it be interesting to carry out this test in a classic fruit dryer which is taken as an alternative to specialized dryers directly for filament?
I checked food dehydrator in my last video. After drying ASA spool for almost 5 hours it went from 993 to 991 grams. Max temp can be set to 70C but in fact there was about 60C at the top. I can perform similiar test with wet sponge.
I have food dehydrator and I am using it. I am working on modification, so I can use it during 3D printing too. When I finish that, there will be a video.
@@MyTechFun I was also thinking about modyfing it to enable printing while drying. Not sure in which direction it will go (adding lazy susan, upright filament stand or rebuilding it from scratch).
That was a very good experiment, and I really liked your method. I happen to have an Eibos and I am extremely happy with its performance. And as you mentioned, there is a like to space available to dry desiccant packages.
Great video, after over 4 months watching this video over and over I decided to buy the Eibos, without any doubt it is the best, but still, after some weeks of working with it, I discovered it has major problems that I would rather describe as design failures. The most inconvenient one is the position of the heating head and fan just underneath the rolls. I had to dry a PLA roll without the need of printing immediately, so I dryed it using the suggested temperature and times. It has dryed, but when I took it off, several coils were deformed in the bottom part, the heated PLA started melting and slowly deforming because of gravity. This is a really bad problem, since this dryer also has the opportunity to contain two spools that rotate independently, so if I'm using one of the two, the other will melt. This could be corrected in an updated model by moving the hot air flow on the rear of the place instead of the middle. This is the first modification I will suggest the producers. The second one is: this looks really great with the squared case, but would be even better with a less intriguing design rounded on the top- front and rear borders (like all other models have), creating a better air flow. If both these modification should be made in a next version of this dryer, I'm pretty sure this will be even better. (another idea could be having a small electrical engine rotating the rollers when not in use, but this would require a more complicated UI to set whether to move or not)
I have the eBox but rarely use it. I tend to use my original PrintDry and I have a fruit desiccator for my 3 kg reels. I think I will use your sponge part of the test to test how the other two are doing. Thanks for the inspiration!
Ended up buying the Eibos one. Seems to be the best of all of them. Its quite pricey for what it is but its an investment and being able to dry 2 spools at a time means I can run 2 to power my 4 printers and can ensure that the filament is dry 100% of the time. It also means im not annoying my wife anymore using the oven. I own a sunlu, Sovol and esun dryers but they are all a bit meh. The sovol is decent because of its seals but it just doesnt have the power needed to heat up 2 spools, and the moisture gets trapped. Seems like the only one that doesnt is the Eibos, and theres some neat plugs on thingiverse you can print in tpu to plug the holes when its not drying.
Very helpfull test, as well as your other drying boxes videos. I have two of the Sunlu S1, mainly for use during 3D printing. Chose those as they do not make any noise. After watching this and your other videos I think I will add a Eibos to use that to predry filament that I am about to use. Or to dry it before I put it in a vacuum bag. Even with the Sunlu S1 I have seen better results with printing. Subscribed!
i use the Sunlu one with no fan. Just dried some TPU that was full of moisture, worked ok. I cover it with a small towel so it insulates the top better, and put desiccant in the spool. I have it running right now, with a hygrometer inside. It settles around 102-106°F inside, currently at 19% humidity. My thermostat says it's 77 ambient @ 39% humidity in the house and 71% outside, as it's been raining a lot here.
Hello, a great video and informative, I do own a Sovol unit but it has the brand Comgrow on the front. However in the instructions it state the cover should be left slightly open to allow the moisture to escape. The cover catches also function as a lid rest to hold the cover open and I find the humidity drops quickly once the lid has a 10mm gap. Without doing this the unit is seals and so the moisture can only condense on the kid. I shall buy a eibos unit and test it also. Many thanks Danny
I tried to redo MyTechFun’s test with a solder sponges but my results were better for some unknown reason: Closed lid 30 min (MyTechFun: 22.3%): 39.3% Fog Closed lid 60 min (MyTechFun: 56.1%): 71.9% Fog Lid partial open (standing on latch) 30 min: 65.5% No fog Lid partial open (standing on latch) 60 min: 102% * No fog *The new sponges were probably not completely dry before the test. Lid closed with four filament holes open didn’t do much difference and it fogged up. Result: Lid partial open is far better than lid closed.
Which one can be run automatic? I just want to put the filament there and print. Don’t want to be manually controlling, it should just turn on when humidity inside fall below a threshold and it will be ready to print .
@@MyTechFun wouldn't it make sense if you can just set the humidity and leave, so it auto turns on when needed. When you want to print the filament is always ready.
What could be the power draw if I just use the Bambu A1 bed set to 70 deg C? My "smart" socket has a refresh rate of once every 2 seconds so it's impossible to say what's the average power draw.
Watching video now. If you don't do it, you should also have a control sponge A) sitting on the table in ambient air, to see how well evaporation works on it, and B) another one in ambient air with a room fan on it, to see how well convection at room temp dries it. These would be good baseline comparisons against the filament driers.
Beautiful work and research! Would have been good to show all sensors in a 'control' box to prove they are all within reasonable tolerance of each other. You deserve more subscribers! Great Channel
This is new product then? I will contact Sunlu if they want a review. I hope it is a quiet fan, because the biggest advantage of Sunlu dryer was no noise.
In the Sovol 3D manual, they write that the lid should not be closed completely when drying, ro let moist out. It looks like you the lid closed under this test?
What you measure is pretty much exactly what I experience: most of those boxes are filament heaters, not filament dryers. After I saw condensation at the top of my Sunlu for the first time, I added a fan and now keep the lid open a crack. Same interior temperature but no more condensation since then...
I’m shopping for one. I was thinking, if my HeatLogic heatable lunchbox was big enough, I could put a spool in there, the filament could thread through the zipper and the moisture could escape through the zipper, too.😆
At the end of the day the Ebox Lite has never not dried my filament so I will continue to use it. I don't really see any advantage upgrading to the eibos for my purposes, but great video.
Definitely not a real advantage to Eibos; You can save 25% of the cost of the Eibos by buying two eBox Lites, which perform nearly the same in thermals.
I have that sovol. I've wondered for a while if I should drill holes in it. I will drill 2 holes in the back (not too many since you say the heater is weak). I also have a fixdry it looks a hell of a lot like that eibos, but it is a little different. It has the same number of holes as the eibos. So I'm guessing the performance is about the same. I also love it because I can turn it on and leave it on. I print with my dryers on the whole time. I found it was necessary with my sunlus, but now I'm wondering if that was because the sunlu wasn't that great. Maybe with the fix dry it's not necessary?
Seeing as there's a big drop in relative humidity when you opened them, should I leave my Ebox lite slightly open to improve venting out the humid air?
Nice one again! You should make the test again but with removed desiccants. I'd love to see how the eSun's perform. I have just grabbed an eBox Lite and it looks pretty good to me.
This is awesome, thank you for the greatly designed experiment and clearly presented results! I am only interested in the dual spool devices, Eidos Cyclopes and Sovol 3D in this case to swap my filament spools for print tasks that last several days in a row. I don't understand why, in the Relative Humidity % plot the Eidos starts at 50% while the others start at around 70%? I think Eidos is designed as a dryer while Sovol can't decide whether it's a heater or a dryer. I can count 17 outlet & air vent holes in Eidos and only 2 outlet holes in Sovol, so the latter cannot efficiently release water vapor when lid is closed. To get a better sense of the drying capabilities of the Sovol, I drilled 2 extra holes in its cover and removed the outlets from the two original holes; then I put two recently open spools in it and set the temperature to 50 °C. By the time the temp monitor reached the target value (about 20 min), humidity had dropped from 45% to 32%; after 4 h it dropped to 22%. However, I think the Eidos still beats the Sovol because of its better air flow design: in Eidos, air flows from bottom to top and out; in Sovol, air has a circular movement around the spool axis.
The Sovol literally says in the instructions that the lid is not designed to be fully shut. Its meant to be left partially open using the latches to prop it up. Which then allows the moisture to evaporate out appropriately. I tested it both completely sealed, and with it slightly cracked open. Slightly cracked open the filament humidity dropped MASSIVELY and in about half the time.
I wrote them an email, but no answere so far. Same to PrintDry. Most of the companies find my channel too small to send the product for free. They think it's not worth it. And watching my number of views, maybe they are right.
I'm honestly surprised there aren't more options for these, and why Bambu doesn't make one. I kind of want the Creality Space Pi because it has a forward facing touch screen and looks nice. some of these look like janky fleamarket Tupperware.
What is the diameter of the rod and the diameter of the bearing which make up the rollers which hole the filament spool in the eSun eBox and the Sovol units? (mm)
@@MyTechFun Ahh. I thought the Sovol had removable/adjustable rollers. Which on has the rollers which you can remove and set in place for either large or small spools.
can you please retest the s2 upgraded with the fan, im curious how it's noise level ares and if it prerforms better than the other models on your current list with the fan.
As an engineer I love how you made this a proper experiment with controlled variables. EXCELLENT VIDEO.

nice video, I have the Eibos for PETG only, I find the heat release enormous in the office, fan noise less loud than the ender 3v2. Remove the black "humidity" label on the humidity sensor of the Eibos, we will also have the temperature in the box in ° F or ° C. 👍
I just got one of these dryers about a month ago, and I was expecting to have to remove the "humidity" label from it to see the temperature, but it shipped without it, so I didn't need to. It makes me wonder why it was ever on there.
Thank you for this video, I have a Sunlu one, but I added fan to it and some circuitry for the fan to be only on when the screen is on and moved the thermal probe up so it really heats up.
same here, saw another guy make a video on it. added a silica gel container inside the spool as well. hopefully its just as or more effective than the others now
Same here. Would be great to see a modded Sunlu in this test as well.! Definitely its increasing the performance but wondering if it is comparable to the others.
@@tanujak98 Yeah, I took that video as an inspiration, but went further. Added a relay controlled by a octocoupler hooked up to one of the backlight LEDs, so now when the timer on the dryer runs out and the screen switches off, the fan switches off as well
@@ptomicek it would be cool if you made a video about it!
I own a Sunlu dryier and was indeed not impressed by its drying performance. I did very similar to you with the humidity and temperature sensor inside and found out that 2 10mm holes, one in the bottom below the heater element and one in the top greatly improved the performance. Humidity inside the box dropped from around 55% to 15% in half and hour. The temperature inside the box was actually higher (don't remember the exact number but about 5 °C) with the holes versus without. Drilling 2 more 10 mm holes did not help any more.
So I ended up with 2 10 mm holes one in the bottom and one in the top on opposite sides to improve the design.
Hi Koen, can I check with you: a hole into the case to the outside? on the top and at the bottom of the case?
Great info! I came down here to ask if he might do just this experiment, I'm glad you can already confirm it works :)
Where exactly did you drill the holes? Outer body or the metal heater?
Can you update us on the hole placement? (Would also like to know if you're referring to the V1 or V2 sunlu dryer).
I along with others would really like to see a food dehydrator compared to these dryers. The only reason I ask is because the Rosewill Dehydrator looks like an affordable solution compared to the Eibos.
These in depth comparisons are very valuable and useful to the community. Thanks Igor!
This guy is so good.
Thank you for the video and the solid data based review!
Super test. But wouldn't it be interesting to carry out this test in a classic fruit dryer which is taken as an alternative to specialized dryers directly for filament?
I checked food dehydrator in my last video. After drying ASA spool for almost 5 hours it went from 993 to 991 grams. Max temp can be set to 70C but in fact there was about 60C at the top. I can perform similiar test with wet sponge.
I have food dehydrator and I am using it. I am working on modification, so I can use it during 3D printing too. When I finish that, there will be a video.
@@MyTechFun I was also thinking about modyfing it to enable printing while drying. Not sure in which direction it will go (adding lazy susan, upright filament stand or rebuilding it from scratch).
That was a very good experiment, and I really liked your method. I happen to have an Eibos and I am extremely happy with its performance. And as you mentioned, there is a like to space available to dry desiccant packages.
It’s crazy to me only the eibos actually works. Excellent video! I was about to buy a sovol
All works great for drying PETG or anything "below". Only for nylon Eibos from these 6, since we need approx 70C for PA
This is one epic comparison video. thank you for the time and effort.
Great video, after over 4 months watching this video over and over I decided to buy the Eibos, without any doubt it is the best, but still, after some weeks of working with it, I discovered it has major problems that I would rather describe as design failures. The most inconvenient one is the position of the heating head and fan just underneath the rolls. I had to dry a PLA roll without the need of printing immediately, so I dryed it using the suggested temperature and times. It has dryed, but when I took it off, several coils were deformed in the bottom part, the heated PLA started melting and slowly deforming because of gravity. This is a really bad problem, since this dryer also has the opportunity to contain two spools that rotate independently, so if I'm using one of the two, the other will melt. This could be corrected in an updated model by moving the hot air flow on the rear of the place instead of the middle. This is the first modification I will suggest the producers. The second one is: this looks really great with the squared case, but would be even better with a less intriguing design rounded on the top- front and rear borders (like all other models have), creating a better air flow. If both these modification should be made in a next version of this dryer, I'm pretty sure this will be even better. (another idea could be having a small electrical engine rotating the rollers when not in use, but this would require a more complicated UI to set whether to move or not)
Was a pleasure to watch. Thank you.
I have the eBox but rarely use it. I tend to use my original PrintDry and I have a fruit desiccator for my 3 kg reels. I think I will use your sponge part of the test to test how the other two are doing. Thanks for the inspiration!
Thank you very much for the video!! Exactly what i was looking for!! 😊
Ended up buying the Eibos one. Seems to be the best of all of them. Its quite pricey for what it is but its an investment and being able to dry 2 spools at a time means I can run 2 to power my 4 printers and can ensure that the filament is dry 100% of the time. It also means im not annoying my wife anymore using the oven.
I own a sunlu, Sovol and esun dryers but they are all a bit meh. The sovol is decent because of its seals but it just doesnt have the power needed to heat up 2 spools, and the moisture gets trapped.
Seems like the only one that doesnt is the Eibos, and theres some neat plugs on thingiverse you can print in tpu to plug the holes when its not drying.
Excellent experiment and results comparison!
You should add real power consumption in the results table, that will be great. Great video, thank you.
Very helpfull test, as well as your other drying boxes videos. I have two of the Sunlu S1, mainly for use during 3D printing. Chose those as they do not make any noise. After watching this and your other videos I think I will add a Eibos to use that to predry filament that I am about to use. Or to dry it before I put it in a vacuum bag. Even with the Sunlu S1 I have seen better results with printing. Subscribed!
Thx, don't forget to check Sunlu S2 dryer too (new version) ruclips.net/video/uVW8kgLKjT0/видео.html
i use the Sunlu one with no fan. Just dried some TPU that was full of moisture, worked ok. I cover it with a small towel so it insulates the top better, and put desiccant in the spool.
I have it running right now, with a hygrometer inside. It settles around 102-106°F inside, currently at 19% humidity. My thermostat says it's 77 ambient @ 39% humidity in the house and 71% outside, as it's been raining a lot here.
Hello, a great video and informative, I do own a Sovol unit but it has the brand Comgrow on the front. However in the instructions it state the cover should be left slightly open to allow the moisture to escape. The cover catches also function as a lid rest to hold the cover open and I find the humidity drops quickly once the lid has a 10mm gap. Without doing this the unit is seals and so the moisture can only condense on the kid.
I shall buy a eibos unit and test it also. Many thanks Danny
I tried to redo MyTechFun’s test with a solder sponges but my results were better for some unknown reason:
Closed lid 30 min (MyTechFun: 22.3%): 39.3% Fog
Closed lid 60 min (MyTechFun: 56.1%): 71.9% Fog
Lid partial open (standing on latch) 30 min: 65.5% No fog
Lid partial open (standing on latch) 60 min: 102% * No fog
*The new sponges were probably not completely dry before the test.
Lid closed with four filament holes open didn’t do much difference and it fogged up.
Result: Lid partial open is far better than lid closed.
a reseller of the eiBos dryer used your graphes on their amazon page...
Great, thanks. I hope they gave me the attribution :-)
@@MyTechFun I cant find the amazon page right now but no I dont think they did, which is why I wanted to inform you about it.
@@mrniffels I will contact with our distributor and double check with them.
Very informative. Thanks for making this video. I use the DHT 22 sensors for monitoring temps in or house for Home Assistant automation program.
Great video which has decided my Drier box purchase +1 Subscription
very excellent video, thank you for setting up and experiment and showing the data
Since this video new dryers are on the market, but I try to use the same test to have comparable values.
Hello Igor, thank you for the test. Shared in one of my 3D printing groups [FR].
Thank you very much!
Thanks for sharing this information. Excellent experiment!
Awesome stuff! this should be a recommended video for anyone interested in 3d printing
Love this video, so clear and smart
Excellent video. Thank you for all the hard work.
Good methodology :)
Which one can be run automatic? I just want to put the filament there and print. Don’t want to be manually controlling, it should just turn on when humidity inside fall below a threshold and it will be ready to print .
None of them is automatic, but very minimal settings. For example with Creality dryer you just need to turn the knob to set hours for drying.
@@MyTechFun wouldn't it make sense if you can just set the humidity and leave, so it auto turns on when needed. When you want to print the filament is always ready.
What could be the power draw if I just use the Bambu A1 bed set to 70 deg C? My "smart" socket has a refresh rate of once every 2 seconds so it's impossible to say what's the average power draw.
Watching video now. If you don't do it, you should also have a control sponge A) sitting on the table in ambient air, to see how well evaporation works on it, and B) another one in ambient air with a room fan on it, to see how well convection at room temp dries it. These would be good baseline comparisons against the filament driers.
12:00 does the variating pulse-like temperature dehydrate better, or is a constant temperature better? like yanking on a heavy rock to break friction?
Beautiful work and research! Would have been good to show all sensors in a 'control' box to prove they are all within reasonable tolerance of each other.
You deserve more subscribers! Great Channel
I'd like to see how the Sunlu S1 Plus performs. It has the addition of a fan.
This is new product then? I will contact Sunlu if they want a review. I hope it is a quiet fan, because the biggest advantage of Sunlu dryer was no noise.
@@MyTechFun It's a new product, yes. It's on Amazon too.
@@MyTechFun There's also he Sunlu S2 too, which you should test as well.
@@ElectricRCAircraftGuyAlready did, one of the first peaces: ruclips.net/video/uVW8kgLKjT0/видео.html but it still don't have a fan.
Very thorough test, thanks for sharing!
In the Sovol 3D manual, they write that the lid should not be closed completely when drying, ro let moist out. It looks like you the lid closed under this test?
What you measure is pretty much exactly what I experience: most of those boxes are filament heaters, not filament dryers. After I saw condensation at the top of my Sunlu for the first time, I added a fan and now keep the lid open a crack. Same interior temperature but no more condensation since then...
I’m shopping for one. I was thinking, if my HeatLogic heatable lunchbox was big enough, I could put a spool in there, the filament could thread through the zipper and the moisture could escape through the zipper, too.😆
I haven't used any of these but I highly recommend the Print Dry Pro. Then store the filament in an airtight container with desiccant
you'd better grab an EIBOS filament dryer before the filaments absorb too much moisture:)
Fantastic work, great video!
Got the Sovol they recommend leaving the dryer open a crack while heating so you might have got better results that way
Exelente trabajo!!! Muchas gracias por compartir!!!
I guess there's only one winner! Us. Thank you.
Yes another awesome video, cheers from oz
Can you also test the Polydryer? I have it and measure only ~45C inside, polymaker claims it is good for drying nylon. Seems low. What do you think?
Incredible work
At the end of the day the Ebox Lite has never not dried my filament so I will continue to use it. I don't really see any advantage upgrading to the eibos for my purposes, but great video.
Definitely not a real advantage to Eibos; You can save 25% of the cost of the Eibos by buying two eBox Lites, which perform nearly the same in thermals.
Excellent review, thanks for the video!
I have that sovol. I've wondered for a while if I should drill holes in it. I will drill 2 holes in the back (not too many since you say the heater is weak). I also have a fixdry it looks a hell of a lot like that eibos, but it is a little different. It has the same number of holes as the eibos. So I'm guessing the performance is about the same. I also love it because I can turn it on and leave it on. I print with my dryers on the whole time. I found it was necessary with my sunlus, but now I'm wondering if that was because the sunlu wasn't that great. Maybe with the fix dry it's not necessary?
Don't drill holes, Sovol can be used as sealing storage box too. Filament don't have so much moisture as that sponge in the test.
Eibos was at 60º, so it was very high for pla, isn't it?
Correct, that's too hot for PLA (and even for some spools)
Seeing as there's a big drop in relative humidity when you opened them, should I leave my Ebox lite slightly open to improve venting out the humid air?
This is very helpful, thank you
Nice one again! You should make the test again but with removed desiccants. I'd love to see how the eSun's perform. I have just grabbed an eBox Lite and it looks pretty good to me.
This is awesome, thank you for the greatly designed experiment and clearly presented results! I am only interested in the dual spool devices, Eidos Cyclopes and Sovol 3D in this case to swap my filament spools for print tasks that last several days in a row. I don't understand why, in the Relative Humidity % plot the Eidos starts at 50% while the others start at around 70%? I think Eidos is designed as a dryer while Sovol can't decide whether it's a heater or a dryer. I can count 17 outlet & air vent holes in Eidos and only 2 outlet holes in Sovol, so the latter cannot efficiently release water vapor when lid is closed. To get a better sense of the drying capabilities of the Sovol, I drilled 2 extra holes in its cover and removed the outlets from the two original holes; then I put two recently open spools in it and set the temperature to 50 °C. By the time the temp monitor reached the target value (about 20 min), humidity had dropped from 45% to 32%; after 4 h it dropped to 22%. However, I think the Eidos still beats the Sovol because of its better air flow design: in Eidos, air flows from bottom to top and out; in Sovol, air has a circular movement around the spool axis.
The Sovol literally says in the instructions that the lid is not designed to be fully shut. Its meant to be left partially open using the latches to prop it up. Which then allows the moisture to evaporate out appropriately. I tested it both completely sealed, and with it slightly cracked open. Slightly cracked open the filament humidity dropped MASSIVELY and in about half the time.
Thanks for doing this!
The Eibos does dry filament too well because of poor heat direction and its a pain to change the filament roles during and active print.
Great video, you got my subscription with this :-)
Awesome, thank you!
Very much useful Specs, Very Unique video i would say, Thanks a lot again.
Really cool test. But I still think the Wanhao Box 2 is the best !!
I wrote them an email, but no answere so far. Same to PrintDry. Most of the companies find my channel too small to send the product for free. They think it's not worth it. And watching my number of views, maybe they are right.
I'm honestly surprised there aren't more options for these, and why Bambu doesn't make one. I kind of want the Creality Space Pi because it has a forward facing touch screen and looks nice. some of these look like janky fleamarket Tupperware.
Great video, thank you!
What is the diameter of the rod and the diameter of the bearing which make up the rollers which hole the filament spool in the eSun eBox and the Sovol units? (mm)
Main middle part of the rod 8mm, Besting not sure, I couldn't take them out, on sovol look like 10mm (probably the rod is smaller dia there)
@@MyTechFun Ahh. I thought the Sovol had removable/adjustable rollers. Which on has the rollers which you can remove and set in place for either large or small spools.
can you please retest the s2 upgraded with the fan, im curious how it's noise level ares and if it prerforms better than the other models on your current list with the fan.
