What do you use for dehydrating your filaments, and why?

I’m reading a lot of posts on this subject.
I’m a semi-noob on this issue except for all the YouTube’s I’m watching. Living in SC/US, I usually have my heat or A/C running and my workroom humidity is around 45%.
If I leave my filament in my printer for more then a few days (I was bad) I notice it becomes brittle and I’m learning it’s from too much water in the filament. Kind of backwards in my mind.
A few weeks ago I got my A1 and AMS, and I love it way more then my last printer. I don’t have any stringing or the normal issues I see that others have but I’m experimenting with PETG and TPU.
I also ordered some Bambu wood filament that it says to dry before using.

I was looking at the Sunlu S1 Plus, then I thought I may need more room for spools so I looked into the S4.
I saw this video where he compares all the models and started looking at the Eibos:

I watched prob. 20 or so videos in the past 2 days, tearing my hair out and trying to get this right.

6 filament dryer test - which one dries better? eBox, eBox Lite, Sunlu, Sovol, Creality, Eibos

The Eibos got some bad reviews on Amazon, so I watched this:

EIBOS Polyphemus Filament Dryer Review!

That looked better but it also got bad reviews; some said it was built cheap.

So…all filament contains water? Things I discovered while testing out the Sovol 3D Dry box.

This last video looked interesting, so I called a friend and asked him. He said “Get yourself a food dehydrator and put the filament in there for 10 hours r so. Problem solved.”

SUNLU Filament Dryer S4 vs S2 vs Food Dehydrator

You all have been doing this way more then I have, so now that I know about the different options I’d like to ask here. I always do my homework first.

I like the face that I could stick the rolls into the Polyphemus, and pick PLA and it works, but if I use a dehydrator, then what kind and how long do I,leave it.

I’ve also watched a lot of horror stories of people cooking their $25 filament and having to throw it away. :sob:

How can I tell if my filament is wet, of if I truly need to dry it?
I keep it now in vacuum sealed bags with a few desiccant packs.
I don’t need a dry box, just dry it and use it then put it away. I can’t use one with my AMS easily.
Thank you for any & all help.

The Sunlu S4 is an easy choice if you use a fair amount of filament. If you figure it will last 5 years the cost is about $30/year. It seems to me that some people doing a lot of printing spend a lot of time trying to avoid the relatively small expense of a filament dryer.

I think that first test is one of the videos that convinced me to buy an Eibos. This graph in particular:

The tested Eibos model does not seem to be available. I’ve been satisfied with the Eibos Easdry because it is one of the few dryers that actually expel the moist air. It never made sense to me to steam the filament when you really desire to dry it.

@lkraus I thought that too. It makes no sense to give it a Sana. I don’t do a ton of printing and @user_1322886946, I’m not worried about the cost. I’m looking for a hassle free solution. I love my Bambu because I don’t have to fuss with it. It just works.
BTW, you can change your user name over in Bambu Makers Supply. It took me forever to find that. :slight_smile:

Air fryer with the ability of dehydrating :grinning:

I was looking at the Eibos Easdry and I always read the bad reviews first.

That rules that out.

I use a food dehydrator. $99 from Amazon - works well takes 2 rolls at a time.

I put a zigbee temp/humidity sensor in all my storage and dryers. I get a history and alerts from Home Assistant. the sensors can register up to 60C.

I’m probably buy the Bambu HT when I can. I don’t know of a humidity sensor that can go into that unit. But it likely will be accessible directly from Home Assistant like the printers and AMS.

I do think that filament can probably be dried with Silica gel if enough is used.

Wouldn’t a cheap food dehydrator have the same graph?

You would think so. I’m Leary of them because I don’t know how long to cook it.

You just follow the instructions on the filament TDS.

Has anyone purchased the Polymaker Polydryer? It looks like a pretty fair machine.
