Teasing aside, this works surprisingly well. The default settings for dehydrate is 150°F, which is well under the glass transition temperature for PETG.
Would not recommend for ABS/ASA. I have no idea what temperature that plastic starts putting out its toxic fumes at, and I don’t want to find out.

Ahh yes there isn’t enough plastic in my food yet, let’s see if we can add a bit more
150F is pretty much the target for PETG in most dryers as well. 60C which is 140F.
The real question is, what is that spool made from? Can it take the temperature? Do you want that leaching chemicals into your convection oven?
Maybe get a cheap one just for industrial use. Like the reflow toaster oven.
Is an air fryer cheaper than a filament dryer?
Maybe from ALDI but certainly not a ninja brand. Food dehydrator might be cheaper, especially from some place like ALDI.
I have one of those round dehydrators I bought and modified for exclusive filament use… it takes up more space than purpose-made dryers, but it’s also quite powerful, only my Sunlu S4 can rival it.
Probably not, but the goal is the convenience of multi-purpose. I can dry a filament for an hour, then wipe down the inside, load the dried filament, and cook dinner while I print.
Also banking on the air fryers capacity to blow larger volumes of hot air at the target temp, given that… Well, it’s designed to mainly cook food. Some of the cheaper filament dryers just do not have enough airflow. Or any airflow.
My questions was referencing this:
Do you want that leaching chemicals into your convection oven?
In which case, you really don’t want it to be multi-purpose.
I have heard about the pet peeve about “single purpose” devices, especially with kitchen appliances. But once you start putting non-food things in your for-food devices, maybe rethink your multi-purpose approach.
You wouldn’t use your table saw to slice bread either.
A ten-second Google search yields a cheap filament dryer for $35, and a cheap air fryer for $25.
Imagine printing a spindle and cutting a slot in the basket and just feed the filament right out of the air fryer
I thought this was film. I was so scared lmao.
Lol just ordered an air fryer / dehumidifier for this exact reason. Thanks for confirming it works.
As the one I ordered can run at <80c the recommended dehumidifier temp for asa. That is exactly what i plan to try it on.
Do keep the glass transition temperatures for your filaments in mind. 150°, or even 165°F may be fine for PETG, but PLA will soften at those temps. Also, check your local liquor stores for anything in the 95% range. Makes a great cleaner in general, and should take care of any unforeseen offgassed chemical deposit issues.
Even though I expect any such volatiles to remain a gas and get shot out the exhaust, it’s better to be safe.
reusable spool!
