This idea for an inline filament dryer hit me this morning in the shower after watching every other flavor of filament drying solution video that TH-cam would show me last night. Unfortunately it looks like my retirement idea is already been done pretty well but at least I found an awesome new channel to follow!
Hi, I hope TH-cam also showed you videos about Drywise In-line drier. It's made having industrial users in mind ( price tag around $2K). It's a solid machine and you can print PA and TPU as easy as PLA. One of the videos here: th-cam.com/video/JKttH_CUqpg/w-d-xo.html
I'd really like to see some quantitative analysis on this, like filament weight before and after, and then weight after running through a second time, and then weight after a full static dehydration.
These should be standard on every printer, imho. Integrated PID control, etc. It only needs a little air flow to move away the evaporated moisture. The new models have a air pump. I modified mine with a small fan..stays blue even in the humid months.😊
Yeh. Saw the earlier unit and this unit. My plan for an inline is based on a longer drying tube. Still uses the blue drying beads. The idea of forced airflow is interesting. The key is heating all the way thru for long enough. Thanks from the sub tropics.
It would be much more effective if they pumped some warm air through the system rather than just heating the filament and expecting diffusion to take the moisture away. I’m surprised it works at all with so little exposure time and no airflow.
Keep in mind my test was with PETG that had been soaked in water. Pretty extreme compared to filament that’s been exposed to just air. They also recently released a new version that incorporates air flow into the dryer. I haven’t tried it out, but it looks interesting.

I saw they released a new one with an air pump. Pretty cool. I’d be curious to know more about your fan mod if you feel like sharing 😀

The company that makes this recently posted that they are working on a prototype that pumps air: facebook.com/share/v/XtHmQVkX9ezn4LBy
They have to be careful to not infringe on existing patents which is what holds back almost all consumer 3d printing.
Excellent video. Thanks!
so it just barely works which is not good.

Nice idea but not ready for prime time.
