Filadry?
Anyone using a Filadry?
Is it legit? and worth it?
I am sitting here listening to my TPU crackling. (I did everything I could to keep it dry! 😡 )
Where would you put it? would you hook up a boden tube, etc...?
Re: Filadry?
Have no experience with with Filadry. Looks like it goes in-line as a powered device using their "patented mix of chemical and physical laws". I'm trying to determine if it uses consumables.
I did get a Print Dry as a Christmas gift and have to say I quite like it. Although it's indisputably based on a food dehydrator, they've added the pain-to-print side panels, provided some spool rollers and grommets to make using it during prints easy. It's a bit cheaper than the Filadry, but also holds 2 full 1Kg spools concurrently. It's recovered about $60 of filament without annoying the Keeper of the Kitchen over the last 3 months. Definitely bulkier, but something to compare.

Re: Filadry?
but with filadry you can store your filament in your fish tank 😀
I have a Prusa,therefore I research.
Re: Filadry?
It is a filament dryer. Interesting.

Even PVA? 😯

Re: Filadry?
To me it seems like a gimmick. Polymers don't absorb misture in seconds, it happens over time. Same goes with drying them.
It takes hours of elevated temperature to properly dry a PLA. I don't know of any chemical processes to speed this up without consumables. I'd be interested in a hands on review.
Re: Filadry?
the idea of warming up some filament is tempting to me.

Re: Filadry?
Based upon reviews, it appears this works.

RE: Filadry?
So how much into the filament does the moisture adsorb?, is it through the whole 1.75mm or is it just a few microns into the surface?
Normal people believe that if it ain’t broke, don’t fix it. Engineers believe that if it ain’t broke, it doesn’t have enough features yet.
RE: Filadry?
One thing that I find amusing is there are so many mods for the extruder head trying to reduce the weight to help combat resonance effects, and this sucker bolts right on top of the extruder head making it heavier...
If you bolt it to the frame and run a reverse bowden tube from the extruder head to this heater you will loose the "preheat your filament" feature. (Though I wonder if that really does anything, other than allowing the cooler areas of the filament path to get warmer than designed...)

It seems it is advertised running with a reverse bowden tube too:

RE: Filadry?
I can't imagine it actually drying a filament properly, even if it heated the filament to just under Tg and put it into a vacuum. The water molecules just take a long time to diffuse out of the plastic. The best I can imagine is it removing some moisture from a surface layer of the plastic using heating in air dried with a circularly regenerated zeolite adsorber. Which would work with fresh PLA in a fish tank.
The biggest warning sign is the "patented mix of chemical and physical laws" they are not willing to explain or share the patent number for. If it's patented, it must be published and thus not a secret. And one can not patent nature's laws anyway ...
RE: Filadry?
After watching the video and reading their "How it works" page, I'm led to believe that FilaDry only removes surface (adsorbed, not absorbed) water molecules from the filament using dry heat and slight vacuum. This has the ability to improve print quality, by eliminating this water from the melting process, reducing hydrolysis, stickiness, oozing and as they say plasticization but will not dry a PVA or Nylon filament.
RE: Filadry?
It doesn't work, at least in this testing. Save your cash.

RE: Filadry?
No surprise at all.
