I watched a few of your videos then bought this dryer (my first ever). You are right it is super loud over long periods of time (my ender 3v2 is louder though haha). You were right again about it needing venting. I tested the dryer with the door shut and cracked open (20mm). When open 20mm it remained at set temperature and reduced humidity by 7% (26 closed to 19% open 20mm). This was tested on the same day same room. 21 degrees temp 52% room humidity constant.
Relative Humidity is a challenging metric to gauge performance because of how it varies with temperature. A quantity of air with a fixed amount of water vapor in it will have its RH drop as the temperature rises. Perhaps it might be informative to derive the Dew Point from the RH and temperature, because dew point doesn't vary with temperature for a given quantity of air with a fixed amount of water vapor in it. (At least that's how I understand it.) In a sealed dryer with a roll of wet filament, you would expect the dew point to go up as it vaporizes the water in the filament, even as the RH drops. This would allow you to better demonstrate the benefit of filament dryers that have some way of actually getting rid of the water they vaporize out from the filament without needing to occasionally open them yourself. Cool review! I'm interested to see the results of the PA drying tests you mentioned showing a little clip of zip ties soaking in water. Cheers from Boston, Massachusetts!
Hey. Thanks for the review. I almost bought one as I needed an extra one. I have the eibos single roll one and it's OK. So I bought the sunlu s4 dryer. It is amazing. I looked at the space pi but as of now we can only get the single roll option. And the fact it only has one option for filament exit also was an issue. Maybe you can compare this to some other ones at one point. Like the sunlu s2 or s4 etc. Tks
I'm currently testing this one as well, I'm quite impressed, although its not perfect, I find it much better than previous units like the one from eSun, its also a nice looking unit and looks great sitting next to a K1C, would be better if it had a compartment for desiccant, I don't like how the PTFE tube can just slide in without any resistance, it should have a bulkhead compression fitting instead of that silly rubber grommet.
The first one who commented the thumbnail, THANK YOU! Not sure if they were inspired by space ship from Guardians of the Galaxy, but to me it give the inspiration ;-)
Hi. You can't test the max temp empty. It needs 1 KG filament in it, and the temp sensor needs to be in the core of the filament and not just in the direct airflow.
Good review with the performance test but the general ease of use should've been more extensively reviewed. I had this dryer and returned it because the fan is loud, front touchscreen is very cheap and often unresponsive, and the ptfe position is at an awkward angle to move filament through. Unfortunately creality isn't a brand that's known for thoughtful well designed products.
There are different products. PolyDryer is good, since you can store the filament too. Pi is stronger for drying (higher temp), useful for nylon, if you use it. Pi plus, for bigger spools.
It may have taken the water out of the sponge temporarily, but if the door is closed the water will just be trapped inside, and the filament will eventually just reabsorb it. Using this to dry filament will either require a desiccant or leaving the door open. The water needs somewhere to go. Either way a $40 dehydrator will work 10 times faster than this overpriced thing.
Oh my goodness. You have finally came down to review that filament dryer. Thank you so much for that. I was looking forward for it for quite a while, And.... I instead I have came up with buying a industrial vegetable dehydrator for my filament for just the same price, cooking them up now on real 75 C (petg).
Fantastic review, I like how you take into consideration all aspects of things, from the physical dimensions of things to the technical parameters. And I like your final consideration for Chinese companies on fan noise. I subscribed to your channel because I like that you consider all aspects meticulously and don't just say...the mains cable attaches here, the power button is pressed here, the filament is put here, blah blah blah 👍
Concerning drying nylon: Based on my own expirience: The 70°C setting on an sunlu s2 dryer is enough to dry PA. I've tried it with nylon trimmer line that sat open to air on a home improvement store for quite some time. The difference is, how long it takes. In a comment under cnc kitchen's video on printing with pa trimmer line ( I've used the exact same as he did), a commenter stated, that pa can be dryed at lower temperatures than the recommended 80°C, but every 10°C lower doubles the time to dry it. This might be something to look propperly into.
this is a great test, thank you for the info! when i started printing there weren't really commercial options that were affordable so i bought a nice food dehydrator that opens from the front. i can fit 6 rolls or so in it, it's really nice. not good for storage of the filament so i have a separate dry box for that. takes up some space, but it works!
It can be made by user, minimal DIY. Drilling a hole and insert 3D printed part to guide the filament (but that part must be temperature resistant, from ABS, ASA, PC or Nylon. No PLA or PETG.
Thank you for the fantastic rewiev! I buyed this one later on, but i'm getting a bit worried since it gets really hot underneath. I wouldn't dare ro place it for some hours on temperature sensitive material. Can you relate or has mine some defect?
I have bought that device, and the fan is really annoying. I have tried to open the housing, but it is sonehow glued to the display and I fear I will break it. Anyone tried to open the housing? I would really like to get a quiet fan.
There’s an exhaust near the front for the moisture to exit, very small hole but it’s there. I’d recommend putting a bulkhead on for the PTFE tube if printing from the drier as the tube will pull in a case a jam. It’s so far a good drier.
i purchased the pi plus, my biggest worry is it would be too loud based on several reviews, however it is quieter than a printer so it is actually a non-issue.
So the folks running 2.85/3mm can't use that tube it appears? I'm not sure I care much for this unit, I like the side of the EIBOS. I wish someone would offer a bit larger one that could handle 3kg spools.
