- Filaments can absorb moisture from the air. PETG and Nylon are more sensitive filaments to this. With PETG user can notice some stringing if filament is not dry. Nylon is even more sensitive to humidity in air, and it must be dried on higher temperatures (above 70°C). Filaments can be dried in oven too but using dedicated filament dryers has more constant temperatures and they can be used during 3D printing process (keep filament dry during longer prints).

I've just bought one of these and I note that the instructions clearly state to leave the cover slightly open to allow the moisture laden air to escape.
Who reads instructions. Well I did and your right. It says the locking feature is for when you have dry filament and you want to store it.
You're not the hero we deserve, but you're the one we need. I expected a "oh yeah this is great!" fluff video. You delivered the most thorough and well thought out review I've ever seen!
Thank you for great reviews! I really appreciate that you take so much time to thoroughly test the items that you are reviewing.
I really appreciate your honest and fair reviews on 3d printing products :)
No music, no ads, that's what i like, 👍👍👍
Glad that somebody finally noticed. No ads during the video, I hate to interrupt viewers with those ads. Music, very rarely, just to fill some longer silent gap..
Thank you - I appreciate you hard work and great advice!
Anyway you spent lot of time to check the difference and it is useful for many people. It's nice to see on youtube then try yourself. Thanks for the video.
Love your very detailed videos, thank you !
Really professional reviews!
Watching you from Argentina!
Keep on!
Thank you. It is good feeling to find out that I have viewers from almost other side of the planed.
Thank you for another great review.
Great video. Bought one, looking forward to testing it out.
And something I didn't mention about Sovol dryer, it has sealing and it can be used as dry box, to store the filament (for example between two printings)
Great review
Thanks for sharing your experiences with all of us :-)
Don't the instructions state that the lid should be left slitly open resting on the lid clips when drying and locked closed/sealed for storage? Mine do so the moisture can escape.
Great video 👍
In that early instructions I got, no, but since it has sealing along transparent plastic part, so filament can be stored inside too (when not drying), some opening is required for moisture to go out.
If you still have it can you redo test with it slightly open? Right now this is one of the cheapest dryers on amazon.
Glad you picked up on that PSU. It's super lightweight and gets, I think, excessively hot. I bet if I crack it open, there's no heatsink in there. I used a PSU from a TV decoder and seems a lot cooler. It should be possible to use sound insulating foam on the sides (foil covered) to insulate the walls - I wonder about the heating element as it's directly on the base and that base gets really hot.
Great job, thanks.
Ďakujem za info, objednané.
Maybe you can do a dryer mod, replacing the control board with an arduino nano, adding some front holes with tubing and adding some insulation to the sides.
Besides measuring the overall temperature, I'd suggest you additionally measure the temperature of airflow and see how precision control of these dryers. I found some dryers may emit too hot air and thus soften the bottom of filament, especially PLA.
its a nice looking dryer but a shame it only goes to 50c at 50c that is really to low for petg to dry correctly and nylon needs 75c so they are way off here to bad i would have bought this dual dryer but it doesnt get hot enough if it wont get to 75c then its worthless to me, but you did a great job on the video as always
These filament dryers should all have vent holes at the top for the evaporated moisture to escape and larger more effective heaters to compensate and enable higher temperatures.
Great review and metrics!
I got one of those, and the instructions says to leave the lid cracked for moisture to escape..wondered if that would've made any difference..
During drying yes, open. But this has sealing on plastic, so you can store the filament in it later. Then closed.
I wonder why they don't put at least some of the desiccant at the top of the drying box to speed up the drying process - moist warm air rises.
I got one to replace the esun i took apart.
its not bad, but i wish it was 24v... I also hate the logic in the stock controller, I may replace it with something diy soon
A regular slow cooker with a timer and temperature control for drying the filament is suitable.
Perhaps if I get some oversized rolls of filament I will steal my mother's old Crock-Pot that she never uses, very good advice!
I agree, only problem is that you can't use it during 3D printing (for longer prints). Another problem I noticed with my oven, is that it's temperature variates +/- 15°C, it may ruin the filament and spool sometime.
It is so sad that in 2021 vendors could not create properly even so simple devices ;(
Are these filament dryers easy to disassemble to for example replace the control and measurement electronics with something homemade?
Not sure about Sovol, but eSun and Sunlu are easy do disassemble and modify. But if I buy a product it would be good if it doesn't need a modofication, instead I would rather DIY one from scratch
Maybe in the last print, the small stringing was due to overextruding, what is the best filament dryer according to you?
The best filament dryer for me is the one which is quiet but also has a fan and space for silica gel. Only for drying nylon I need Eibos filament dryer, all others can dry other material and keep nylon dry during 3D printing.
What they'd really need is to know the outside humidity and bring in the lowest humidity air. This looks like a simple heater/fan in a sealed box, so it assumes that inside the box is less humidity than outside.
The real test would be to take room humidity and room stored filament and then put it in there. I'm guessing that if you put the filament in an oven first, and fill the box with hot air, it would maintain the low humidity.
I wonder if a simple container with a cheap hair dryer would do the same or better.
Hello. Can you share the size of your large filament reel. The orange colored one. Need the diameter and width please. Thank you for the excellent reviews.

Hi, I'm thinking about buying a dryer, which one would you recommend from the ones you reviewed?
From tested by me this one is the best. But I have Creality dryer waiting for the review. It works on ac power, 150W. Video in week approx
@@MyTechFun Thanks, I will watch it!
Why does nylon need 70c? Ive seen this stated in multiple places but surely 50c will still turn the water into vapour?
Drying has two main steps. 1st hi temp to force the humidity from inside to surface of filament. 2nd low humidity in dryer, so moisture evaporates from filament
Tho cover could have holes in it so the moisture can escape.
Yes, later I find out, that their design is max sealing, so it can be used as storage box too. But I don't think that people will use this just as a storage box.
Haha, looks like they should have put that power brick inside the filament drybox to harvest the power a little more :D But on the other hand, i don't necessarily trust them if they did that?
Good thinking. Probably it belongs to different category if AC power goes into product..(harder to get some certificates)
@@MyTechFun Also you aren't exactly allowed to run those bricks in a hot box. You'd get a bare unit and validate/derate it as-needed. Then of course all kinds of potential safety concerns and cert/test considerations. Probably not of regulatory importance, but relevant to the device in question: what if someone accidentally loads the dehydrator with corrosive calcium chloride beads instead of the inert silica ones? Much safer in a Class III Appliance.
Now it's the turn of EIBOS filament dryer
EIBOS, never heard about them. How popular is their product? Maybe I should ask them if they want a review :-)
@@MyTechFun it was launched recently and there are a few reviews
Your experience with the sovol is not the same I had. My unit is identical but the heating element never goes higher than 50 deg C and the temperature inside the box is uneven . It takes hours to have at least 45c at the base of the box and it never reaches 40c at the top. So for me it is totally useless.
YEAH SCIENCE!!
I waited for this video and.. noooo: only 50°C! Damn!
I'm still waiting for an filament dryer what can heat hotter.
printdry is only one i found that can heat to 75c but its expensive
Soon I'll test Creality dryer, AC power 60C, we will see..
@@MyTechFun www.printdry.com/product/printdry-filament-dryer-pro/ its 180.00 way to much but the only one i found that goes from 35c to 75c
I have it. It’s 4 days now.
I’m testing.
Improvement :
Insulation
Higher temp
Spinning rollers
Two out holes in the front and top with plugs
Bigger fan
Faster speeds
More time settings
Price is too high.
I agree, thx.
Insulation. None on the market have insulation no doubt to keep them smaller and cheaper.
Higher temp
Spinning rollers. They have bearing spinning rollers.
Two out holes in the front and top with plugs. you can do that yourself if you want.
Bigger fan. The fan is plenty big enough for the job in hand.
Faster speeds
More time settings
Price is too high. I got mine cheaper than some of the 1 reel holders by jaylo, esun or sunlu.
I bought a food dehydrator with the same specs (goes to 55C) and volume for 25 pounds, so I can't see why this is so overpriced. I also don't get why they won't add better functionality to it, I could probably do better programming with an arduino in a morning.
I have dehydrator too, only I can't use it during 3D printing (recommended for nylon printing).
Yeah the dehydrators are produced at greater volume and don't have rollers inside... Consumer dryers are a niche product.
@@MyTechFun I've been thinking of something like this : th-cam.com/video/p1AQQ41gFDU/w-d-xo.html
14:24 - Too bad they didn't integrate the power supply into the base of the unit to utilize the heat given off.
Great thinking. I think product has different rating if A/C power goes into it, complicater to get some certificates (especially in EU)
@@MyTechFun
That is correct. Buying an approved stand-alone power-supply that provides extra-low voltage to the product means that you don’t require safety testing. This testing costs a lot to have done.
Besides the testing, it's also trivial to supply a different power supplies with different plugs for regions where they don't use 230v
@@WoLpH For ‘universal’ supplies, yes. These aren’t the best option for efficiency, though, hence the heat.
