Remarkable to find those levels 1, 2, 3 and 4 for drying. Of course hot plate TEMP is not relevant for the drying process, but the inside TEMP is. And I think eSUN uses really low temperatures to dry the filament. I am currently experimenting with a food dehydrator. It is only 250 Watt so the temperature maxes out on 53° Celsius. I need a bit more temperature (except for PLA) so I added isolation material around the casing. I could raise the temperature inside the food dehydrator to 62° Celsius in that way. I manually adjust the temperature by turning the control knob and keeping an eye on the temperature reading. Therefor I use an external sensor attached to the filament spool inside the upper compartment of the food dehydrator. The lower compartment contains the ventilation fan and the temperature control. It takes a while for the temperature to stabilize so you have to guard the process for a while.
Prusament PETG PPE edition is not meant for selfish use like testprints but rather for printing faceshields. Hence u got punished with too wide spools. :3 Nice detailed review. Greetings to Hungary!
Mine arrived today and I already fixed my PLA stringing... it may not be the best for nylon, but I'm very pleased with the result for PLA. I'll test it on PETG now
Again very interesting and great video but 3:20 That isn´t Prusament. That´s PM Filament (Plasty Mladeč). Prusa sell´s them becouse they are Prusa quality.
In the meantime I found the invoice. "Prusa Orange PETG", nothing about Plasty Mladeč info. In description I will just write "Prusa Orange PETG" as used material. Also, no info on the website, this is the one: shop.prusa3d.com/en/filament/218-prusa-orange-petg-filament-1kg.html
Mine has a different noise that's much worse. PLA filament squeaks when it moves through the tubing. I think it's the fitting on the body of the dryer.
So this looks like a sunlu s1 (or cheaper/identical jayo s1) with a fan mod is every bit if not more effective at drying than the ebox. Soldering a 40mm fan into the 24v input people have reported almost 55°C inside temperature (not near the heat plate).
Thank you, very informative good real world scenario testing. I just wonder how strong the effect of relative humidity with different temperature on the filament is. Because when you calculate the absolute humidity for example for 5°C and 100% RH compared to 25°C and 30% RH it is about the same (6,9g/m³).
Good point. I didn't do this calculation. But anyway, leaving out PETG filament overnight really resulted very bad printing. In the morning, surface was wet, when I take it inside to 25°C. It would be good to have similar Relative Humidity and Temperature chart, only not for AIR but PETG filament :-)
@@MyTechFun Yeah, no question about the test results. The difference was obvious and if the filament has liquid water on it I think that simulates worst-case scenario.
Nice and interesting video Igor. Thank you very much. Is the use of silica dessicant essential or the heat and air flow by itself does most of the job?
@@yoni9600 The best is below filament glass transition temperature. But you need some safety factor (at least 20°C). Higher temperature will easier "force" humidity from filament to surface.
Yes, but be careful, usualy oven is not precize, you can easily overrun the desired temperature. And also, you cannot print directly from oven (for PETG not important, but for nylon, yes)
I do not recommend buying the Esun Ebox.I have bought the esun ebox. Before long she broke down. 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.
I got one and works very well, i used to dry tpu, in 5 hours was very good, but the construccion is a little weak, the plug conector sundenly get off, so i glue it with hot glue :)
Amúgy jól szolgál az eSUN box, a TPU-mat helyrehozta. Már figyelmesebb vagyok a tárolásnál, zárható műanyag doboz (obiból) plusz indikátoros szilikagél és páratartalom mérő.

Subscribed to see the comparison of the Sunlu to the esun. The sunlu seems better overall, but the weight scale is a nice addition to the esun. So far, I'm only into petg so both seem like decent options to me.
I ordered some humidity/temperature sensors for Arduino, I want to use them to equally measure what's happening inside.. When they arrive, I am starting with experiment..
@@MyTechFun guess it needs a small motor coupled to the fan and one of the rollers and a silent fan, with a switch so it doesn't spin when you are printing
Finally I find a review for the esun one. Awesome work, you got a subscriber. I'm trying to decide between the Sunlu and eSun dryer for PLA, PETG and ASA. Do you have a preference so far? The eSun dryer seems that is a bit noisy and insolation is kind of bad. I may go with the Sunlu, but maybe you have more insights...
I'm waiting for a eSun vs Sunlu comparison video as I prefer the look and the weighing function of the filament that you get with the eSun but the Sunlu would be quieter and maybe run hotter.

Ahogy írom a sorokat kb. két nap múlva kapom kézhez a dobozt és máris egy kicsit csalódott vagyok a videód kapcsán. Azt gondoltam hogy az elektronika egyszerű ami benne van de relé kattogásra (lehet hogy reed relé) zajra nem gondoltam, igaz ventilátor csere megoldhatja vagy kisebb fordulatszámra átbarkácsolni. Pla, asa és petg anyagot használok amihez talán jó lesz. Amúgy néhány pla anyagnak is egy idő múlva kell a szárítás, tapasztalatom szerint a "matt fehér" színű anyagoknak mert ezek jobban szívják a nedvességet valami oknál fogva, valójában ezért vásároltam. A többi anyagnál nem tapasztaltam nedvességet amúgy is nyomtatás után vissza csomagolom néhány elfáradt szilika géllel. További szép napot Igor.
Köszi a hasznos részletekért. Kár, hogy barkácsolni kell egy kész terméken.. Nemsokára összehasonlítom eSun és Sunlu szárítókat, csak várok pár Arduino szenzorra... már úton vannak, remélem elhagyják Kínát ottani új év előtt :-)
Hi! Thanks for your review! I wonder what was the power consumption on level 4? I suspect that probably the default power supply 12V 3A is either not enough or it is of bad quality and cannot deliver full power. On my eSUN dryer box there was no clicking noise, but the fan noise was terrible although not too loud. I mean, every 10 seconds it changed speed back and forth. I could get used to a constant noise, but it is impossible to get used to the ever changing noise. As a result I replaced the fan with a silent Noctua fan, and now the noise no longer bothers me. But I noticed that the voltage on the fan changes from 12V to 11.5V about every 10 seconds. This makes me think that entire problem with the dryer box can be fixed either by changing to Meanwell 12V 3A or to another power supply 12V 5A.
I just did a review of eBox Lite, and there also no click noise. Was that 12V Noctua fan? My latest comparison video: th-cam.com/video/yuK9r0VKQTE/w-d-xo.html
@@MyTechFun, yes, a 12V Noctua fan. It would not just fit in the place of the old fan - I had to cut some plastic off from the fan holder and then use some hot glue (or better silicon). I have a regular ebox, not the newer lite version. I believe you could replace a relay with either a solid state relay or a mosfet module as well.
So, an update: I measured the current for the regular ebox, it draws about 2.4 Amps at full load, and the voltage jumps from 13.4V to 12.7V and back. This likely means that the power supply is probably not the best one but sufficient enough for the task. My next step to improve the ebox would be to try and put it tightly inside another box with some thermal insulation.
Thank you for testing so deeply! After the 2nd test of a filament dryer: Why are both so weak temperature-wise? Although a (loud) fan is installed it does not manage to swirl the air at the same temperature? I'm a bit disappointed with these offers. Is there no device that does it "right"?
Thank you Igor for your very informative video. I like your test methods and explanations. Best wishes from Perth Australia

Nice and interesting video Igor. Thank you very much. Is the use of silica dessicant essential or the heat and air flow by itself does most of the job?
Filament drying has two phases: heat force the moisture to the surface, and then air, dryer environment is needed to evaporate from the surface
Mine didn't come with desiccant and even if I put one back there, it either blocks the fan or worse, gets chomped on by the fan blades.
You should put it behind the fan, to the slot. :)
Looking at these results, I'd rather stick to my food dehydrator. At least that will hit 60c air temperature (set to 70c), and is much cheaper.
Compared ta food dehydrators, the static, vertical position of the filament spool seem problematic indeed.
Hm. Great idea. Problem is given, let's find a solution.. (give me a month or two :-) )
Nice video.
Interesting if 80-90c in the oven will dry the nylon.
Probably yes, but also pay attention to the material of spool. Some plastic can't handle this temp.
@@MyTechFun you could have rolled like 20 meters like you did with the petg.
i am just interesting what temperture is the best for it to dry 100%.
@@yoni9600 The best is below filament glass transition temperature. But you need some safety factor (at least 20°C). Higher temperature will easier "force" humidity from filament to surface.
I've seen some tests about this already and usually one or more spools don't fit so it's pretty useless
Why nobody told me that before? :-(
Can you dry the petg in an electric oven?
Yes, but be careful, usualy oven is not precize, you can easily overrun the desired temperature. And also, you cannot print directly from oven (for PETG not important, but for nylon, yes)
I would buy these, if they were without the electronics and 5 bucks a piece.
I have two of these and they are garbage.

Strange way to arrange the division for the vertical result. I would rather suggest that the dried is 43/29 = 48% stronger than the wetter filament.

Perhaps using a pressure vessel, vacuum pump and mild heating could be the most effective way of removing water from a filament?
CNC Kitchen did a video about using a vacuum to dry filaments. It wasn't very successful.
@@ianhaylock7409 It needs to be coupled with heat. Boiling point of water is reduced under low atmospheric pressure.

They are good with drying of PLA, PETG. Low temp is not enough to dry Nylon, but it is enough to keep it dry.
