- Filaments can absorb moisture from the air and this may have negative effect to 3D printing. Some filament types are very sensitive to this effect (PETG, Nylon for example). Filament dryers can dry the filament or keep the filament dry during the printing process.
In this two video eSun eBox and Sunlu Filadryer S1 are tested. On this channel, you can already find detailed review of each product. In this episode you can see hardware comparison and two tests, to find the answer to question: Which one dries better?
In test I used two HDC1080 temperature and humidity sensors (with two Arduinos).

This is one of the best comparison reviews I've ever watched. Thank you for taking the time to make this. It is a lot of effort to deliver a consistent comparison.
@Ivan King ツ Oba su sranje. Novi Sunlu Filadryer S2 dolazi uskoro. Sušiti filament je vrlo korisno ali bolje kupi novi model.
Your commitment to check for dryness is just great, thanks for showing the capabilities of both filament dryers! :D
Crazy how this video was posted just as I was looking for a filament dryer. Thanks for this! Such a niche comparison but helpful nonetheless.
Wow thanks for such the thorough review! Really appreciate that you went to the lengths of experimenting and collecting data.
@12:35 I love how detailed you got with this test. So nice to see how well they dried.
Excellent tests. I received a Sunlu S1 yesterday and was curious whether I should cover the second hole in the lid.
You answered that question for me.
That fan noise would drive me bonkers. Thanks for the video. Really helped me make a decision.
Great job and thank you for the thoroughness of your testing! Loved it.
Thank you for the valuable info. I almost thought they were idential products with just different brand names.
Love your video's, you could always stick decicant in the centre of the spool in the sunlu drier.
Great tip! I'm almost ashamed, it did not come to my mind. Thanks :-)
Great comparison! Thanks for the awesome video!
Suggestion: pick better colors for the next graph you do. It was hard to tell them apart..
Very helpful review, let's get him bumped up in the YT algorithm!
I don't often comment videos. But this was pretty awesome. Congrats and good luck with your projects :)
Excellent review as always
Just came here to say the Sunlu box I bought off A)Z company was completely broken with bad solder points and constant errors. I bought the eSun box and it works perfect out of the box and has been wonderful for weeks now. Thanks for your video, subbed.
Thank you Igor for your in depht comparison of filament dryers. Would be nice to follow up with converted fooddehydrator as filament dryer.
Love your videoos.
leaving a comment for the algorithm. honestly a wholesome and very detailed review, thank you!
Much appreciated!
That was a lot of work to this review. Nice!
great content.
in excel you can paste your CSV data directly into excel. after you do that, there's a little box that you can click (paste options i think, should be at the bottom right of your data input), and it'll bring up a menu for you to select the type of data (delimited) and what kind of delimiter to use (comma) and then it'll bring each value into a different cell
Excellent comparison and great DIY arduino work!
Hi everyone if you want to make the eSUN dryer more quiet just change that 4010 12V 2pin 22cm wire length fan with a quieter one and paste some soft material in it, the noise and vibration will gone
Many thanks for this. It appears that having some means by which the humidity can be reduced inside the dryer is an important aspect. Desiccant can become saturated and a 5mm hole seems a rather inadequate solution.
Amazing review bro!
Very nice experiment. Thanks!
Thank you very much for this! I'm one week into my 3DP journey, so filaments and accessories are high on my list now.
Oh, snap! The twist at the end was excellent. I'll look into picking up some of those sensors. I have a cheap hygrometer that can't be calibrated, and it seems to be inaccurate and slow to refresh, so a diy option will likely be better (and more fun!). Cheers for an excellent video. Subbed :-)
14:00 You should not tapeof the Sunlu hole.....that way moisture can get out....
I have chosen the Sunlu because it is quiet. It significantly improved the quality of my prints, e.g. drying a 2 months old PLA filament overnight can reduce the stringing almost completely. When you use it during printing, the filament spool rotates inside slowly, so the forced air circulation might be not needed. What I don't like it's menu, I don't fully understand when it accepts the new timer settings.
Comparing the relative humidity values on different temperatures might be misleading, the dew point value should be calculated for each for direct and easy comparison.
Thanks so much. I've been debating between these two for weeks!
Nice review-comparison. I however find the simplest and cheapest dryer comes with your filament: the box. Pop in the filament and place it on the hotbead of the printer. Add a temp/humidity meter and you're set. Dried filament keeps very well in a plastic box with dehumidity salt on the bottom. Drill in a small hole in the side and you can feed directly to your Printer. Even tested it with my nylon spool.
Excellent video! I planned to skip through to get the information but I didn't skip once. Thanks for all the detail. I can't help but think that a bit of convection would help both of these boxes actually remove the moisture from the box and not contain it.
This may be usefull too: th-cam.com/video/6VB-pEvSed4/w-d-xo.html
Try adding some air circulation for more even temperature in the whole dryer. I used 40x40 fan with speed controller and it works like a charm!
very good testing
Thanks for doing this, was interested in the differences between these two.
thank you for splitting your video into a conclusion section!
Great test as always
Thanks for taking your time to make this review :-)
Thanks bro
On the Sunlu, you have to hold left or right button. Right button is Moisture display and left button is timer. Grtz
Thanks for the good comparison. I wanted to let you know I just received the Sunlu unit and I can dry nylon in it. I have a couple spools that are at least 2 years old and I was able to dry it and print like it was new. Probably just takes longer. I had it in their for close to 24 hours.
Thanks for the info! Also placing silica gel inside spool also helps. But I have better results with food dehydrator, only during printing I am using eSun or Sunlu dryers (for nylon)
Yeah, I just ordered and received a pretty large one. The rectangular kind with 9 trays. Basically a clone of the one Joel showed in his video.
Thanks for your video share
Thanks i was waiting for your review to make a decision
Thanks
Excellent!
half way through the video but I want to share my experience:
I built my own cereal box filament dryer using homemade heating element and blower fan similar to eSun. However, without extra heatsink the heating element reached max temp (80°C) very quickly, but the other parts of the box are still too cold for sufficient drying, which means it's bottlenecking and it doesn't use all the watt it can reach. I then added 2 45*45mm heatsink to it and now the bottleneck is the power. The 50W heater couldn't get the box to 60°C I want even in a hot day.
Later down the journey I read reviews about eSun's bad thermal performances, most of them are the temperature never reach what it should get. Which make me believe eSun box is just a flawed design.
And both products have no consideration about air exchange. The water just evaporate and condense inside the box which is not good for what it's for. Ideally you will want to displace the air inside the box with a dried air or just less humid air from outside.
The eSun has dessicant which works much better in a sealed environment which is why no air exchange.
The Sunlu has no excuse, it's just terrible.
I received my Sunlu Filadryer S1 today (31-01-2022) from Banggood. It stated "Filadryer S1 Plus" on the box. It actually does have a fan, it looks like a 4010 radial blower which is placed in the lower front part of the dryer (behind the screen casing) underneath the curved metal heating plate which has an opening there. It doesn't make much noise. I think it's a nice upgrade for this "Plus" model.
Good to know, I didn't know about this new dryer. It would be good to test one and to compare with S1 (no fan version)
Thanks!
Thank you Christopher! I am happy that you liked the video. There filaments are tested in another experiment, but here you can see all filament dryer videos on mytechfun channel: www.mytechfun.com/videos/filament_dryer
Love your videos. Quick note. You can change the address using adafruit library then you dont need 2 arduinos
Thanks for the tip! I didn't know that.
Wow!
Hello My Tech Fun
Great video. The design of these two dryers is poor at best. Not having the moisture displayed in a filament dryer is like a car without a speedometer. You would think that moisture sensors cost allot of money for them to leave them out. And the eSun not displaying the temperature is just wrong also. Sometimes I really wonder who designs these things?
Thanks for taking the time to make this video. Enjoyed watching it.
Cheers
Willy
I bought the esun and I find it great. Especially the weight is very useful. As for the clicking and the fan noise, it is a bit annoying, I plan to install a low noise fan.
use noctua 12v 4010. i tested, works ok. using buck converter to silence fan ended up with failure since not enough circulation, it doesnt heat inside
Is the esun good for tpu and nylon filaments?
@@individualone esun is good for any type of filament
Your table of pros/cons seems to suggest that because the sunlu one shows an operating temperature that it has a thermistor. Many devices that create heat and have a temperature display do not have thermistors. They are usually dumb devices that apply a certain amount of power to create an approximate temperature, but there is no feedback loop. I wouldn't be surprised if that was the case here. Actually if either one has one it is probably the esun because it clicks on and off. Maybe try blowing a hair dryer ON COLD at it while it's running and see if it forces it to stay on. That's assuming you can hear the click over a hair dryer.
The best part: "What a mess, i should clean this before my wife gets home" hahahahaha Thank you for your great evaluation!
in both there are no holes on the top to get out vapour from the drying process. the humidity stays inside. if you have a look to the drying food machines there are holes on the top. even if you look for professional dryer filament which cost 5x, there are always holes on the top.
So do you recommend drilling holes?
@@chrisz.9974 yes, 4-6 of 1mm hole
Like your test(s)! :-) I have the Sunlu and I will use it only for long print jobs, to protect the whole spool of filament from absorbing moisture during this time. For drying, I think a cheap food dehydrator is the better solution...
I agree. I am preparing one, but I want to try to modify it, so I can use it during 3D printing too. And to add some temp and humidity sensors..
I have two of the Sunlu driers. I hate that they can not be set to remain on for more than 24 hours. (There is no setting to just turn it on) My current print will take 6 days so I have to restart the filament heater every day at the same time. I can't just hot wire it on all the time because the same microcontroller that controls temp also shuts it off every day!
Hello and thank you for this wonderful and very precise test. But have you measured the actual consumption in 4H or 2H of each of the boxes? With the current price of energy, this is important.
What's a good value for humidity for storing filament? I keep my filament in tupperware type tubs - they have airtight lids, and can hold four spools each. I put in dessicator pouches that they sell here - they contain, I think, calcium chloride plus a gelling agent, and are sold to be put in drawers or cabinets to keep mildew out of clothes. There are pouches as well as tubs, Tesco and Daiso sell them here. You can find scented, unscented and odor-absorbing varieties with activated carbon mixed in. I put miniature hygrometers on top of the filaments (you can get these from pet stores - people use them in terrariums for reptiles - there are analog ones and digital ones). Generally, the pouches keep the humidity down to around 18-20%, which I think is pretty low. I wonder, if you put a spool of nylon in there, if it will dry out by itself in a week or two.
Szuper videó! Épp ma érkezett meg a Sunlu szárítóm. Meglepődtem amikor bekapcsoltam, és tényleg semmi hangja nem volt. Viszont az eSun-nál tetszik a bowdenes megoldás. Valami hasonlót kitalálok a Sunluhoz is.
Hat igen, egy kis DIY munka nagyon ajánlott: bowden tube, silica gel tartó, talán egy ventillátor.. Csak az a fránya max 55°C kevés (valódi 43°C)
@@MyTechFun silica gelt betettem a filament spool közepén levő "csőbe". Meglátjuk, hogy mennyire lesz hatásos. Ilyen DIY megoldású szárításnál sok helyen azt olvastam, hogy PLA-t konyhai sütőbe tenni, 40°C-ra 4 órára. Ha ezt nézzük akkor nem is olyan kevés az az 55°C, de majd az idő eldönti. Igazából nem tudok tapasztaltan beszélni róla 1 nap után.
Many thanks for this great video. Do you think it would be possible to place a silica gel bag into the Sunlu dryer, maybe to print some holder and mount it in the top corner on the inside? And would you recommend it to reduce the moisture in the Sunlu?
Yes, there are a lot of modifications on internet how to add silica gel holder and FAN to Sunlu dryer
Finally whis is better? Which can I should buy?
Just recirculating humid air without at least adding a fresh air from the outside is a wrong way for drying. It works, but barely. If you're into the diy drying box, the simplest and quietest to make is with the peltier element. It's not energy efficient as rotating dessicant or compressor type, but it works better than just plain air heating.
Key is in reducing a partial pressure of water vapor in the air used for drying by first cooling it to the dew point and then heating it to the needed temperature. Condensate needs to go to a separate container outside the drying box.
Just remember in the winter how dry the air is in the room when you ventilate it with the fresh cold air from the outside and then let it to warm up.
Marko, thanks for great and informative comment.
This might work better if you open up say a 6mm hole in the top center on both and a matching 6mm hole on the bottom even better is make a descant dryer and use a air pump to pump dry air in
You can put silica gel in the middle of the spool
Very nice test, but it does leave me with one little question. How equal is the temperature throughout the box. I wouldn't be surprised if the temperature delta of the top of the box vs the bottom is different between the two due to the (lack of a) fan in the sunlu and esun respectively.
It's not equal, but in comparison I tried to measured it at same place. Usually if you are using during 3D printing, spool is rotating slowly.
Given they are roughly the same price I think the esun is the better. It can weigh filament, it has a built in fan to circulate the air. That said I dont really think you need either of them, none of them do as good a job as a proper food dehydrator or oven.
I agree, I mentioned that in a video. But advantage of these dryers is, that they can be used during 3D printing too. And temperature is enough for drying PLA or PETG (tested in review videos)
I am using a Ivation model IVF290...drilled a hole in the top of it, installed a Bowden tube fitting.
I can run a print and dry out an additional roll at the same time.

Great video ! Would love to see a video about dryers for nylon as that is my interest.
I am preparing a modified food dehydrator. Main factor is given: over 70°C, only I want to try to modified it so I can use it during 3D printing too. And to add tome humidity and temp sensors..
@@MyTechFun I look forward to this video , but I wonder what temperature would be required for a "universal dryer" , my interest is in nylon as I said but would also like to experiment with PPSU some day . if 70C was adequate for nylon but 110 C was adequate for all plastics (for example) why not at least consider it ?
@@MyTechFun I just had a thought , If I understand correctly Microwaves directly heat the water in foods , what about a modified microwave oven where the air is recirculated through a bed of desiccant ? Microwaves have gotten very inexpensive ! Additionally there may be time and energy consumption savings that could be factored in.
Where are the affiliate links for the dryers and this temp/hum-sensor you used? ;-)
They are in description of the video. First 3 links :-)
@@MyTechFun oh! ok, had to reload the video to see the description... (probably you haven't added them before, at the time I saw the video)
Is there a heater you recommend for nylon? Or do you just use your oven?
From tested so far, none for nylon drying. They can keep it dry during printing after you dry it in oven or food dehydrator. In the meantime I got Creality dryer, ac power 150W, review soon..
Drying by heating is very inefficient, especially in an uninsulated box. You also need to use airflow to remove the moisture from the box. This air brings in more moisture! The period of heating will be limited (hours). It consumes energy. The fan makes a noise. Six problems, so far.
Compare this to a sealed box (cassette) with a substantial quantity of desiccant within. Much lower level of moisture achieved, works for weeks (life of reel); filament never leaves the cassette, so no deterioration when mounted; Silent; low energy requirement (regenerate silica gel in microwave); cheaper .
Dessicant only in eSun dryer? Kinda invalidates the test, no?
I do not recommend buying the Esun Ebox.I have bought the esun ebox. In no time she was spoiled. In 3 months she stopped warming. The seller did not repair it or give any solution. The scale to measure the weight is poorly designed and the result will vary a lot if you tilt the filament a little so it is not reliable.
Hi. Who is the winner?
I don't understand English well.
I use PETG and PLA.
Which one should I buy?
If you are ready for some diy work, go with Sunlu to add fan. eSun have new version now (eBox lite, I have a video about it), that's better than this old eBox. Sovol has also very good dryer, 2 spools can fit inside.
@@MyTechFun Thanks
Could you increase the performance of the ESun Box by adding some instulating tape to the sides?
Probably yes, but not much.
Good comparison! Now I regret buying one and not building one myself. :)) They are both meh. I'm waiting for a eSun dryer to arrive from Amazon. PS: That sensor is awesome!
no need, I live in low humidity LA
These look like quite useless to me. Not much smart design went into them it seems. For example Ultimaker advises to put the roll of filament in its cardboard box on the heated print bed. I can also imagine a nicer box built on that idea - perhaps a large pan, heating sticker on it and perhaps a cheap PID controller (and overtemperature fuse...).
With the advantage of higher possible temperature, larger size, and lower cost.
If you decide to sell your DIY dry box do let me know.
The amount of water lost from the sponge may be due to differences in surface area and density.
Yes, but it is very different from the filament. These dryers are designed to dry filaments only (but limited with temp.)
After this review, I think I'm just going to DIY a dry/heater box. These manufactured boxes don't seem to have any real benefit over making one for less than 1/2 the price.
You're getting a "Like" for a great video, and a "Subscribe" for being a fellow Hungarian maker.
Thanks, Creality dryer is also on the way, will be tested when arrives. It uses direct AC power, 150W
Sorry. First test ... negligible amount of filament compared to air volume in box must works with added temperature always...but more filament means smaller air amount that can absorb humidity (and it is limited with temperature and pressure). When there will be kilogram of filament, how much air will be there for absorb humidity ?! Second test really perfectly shows that both boxes are for nothing - humidity is still same (no matter what was put to boxes) - it cannot be dried without air-change between box-room. But both boxes are closed. Physical laws are valid still...both boxes had to design a person ignorant physics. Without small input/output holes and slow ventilator it cannot works.
Hi everyone, I have the Sunlu dryer. I have the problem that when the spool gets lighter the spool lifts and does not turn well. I have had that the printer pulled the dryer from its place and impacted the print quality. Has anyone else have the same problem?
I didn't noticed that problem (yet)
eSun sounds like an old harddrive lol
Too bad you don't have a 3d printer, or you could have printed a new plug for the Sunlu
Nice work. Hope you had it cleaned up before your wife got home. Lol 😂
Yes, almost in last moment :-)
None of them has great designs IMHO. We can 3D print ourselves something way more effective at cheaper price with 5-dollar mini hair dryer, an STM32 (or another microcontroller), some mica sheets and a cheap sensor as the one you have used in the test.
I think you need to clean your scales!
My wife told me too :-) (scale is from my workplace lab)
damn the eSun is to small that makes the decision easy
Both of them are bad, you need to add a fan, and include a silicon desiccant inside to get powerful results. It's overpriced and flawed.
中国的产品好用吧
The SunLu PCB actually has a location for a fan connector but the PCB was crippled by leaving the components out.
