One Way Valve for filament (check valve)
Hey there!
I have made a check valve for filament with the balls of an 608 bearing.
You can use this for your MMU setup.

Re: One Way Valve for filament (check valve)
I'm confused. What is this for exactly?
Re: One Way Valve for filament (check valve)
It's a really nifty way to stop filament moving back to the spool when used with an MMU. It would replace the dual lever system Prusa uses.
Re: One Way Valve for filament (check valve)
As Martin said, but this is meant to be a concept. You can use the idea for your own filament spool system. I am working on some compact and airtight solutions for MMU where I use this and it's working perfectly.

What happens to the unloaded filament if it has nowhere to go?
Re: One Way Valve for filament (check valve)
could you change the file to have a solid top, no insertion hole, no screw hole, then print 3/4 height, pause, insert ball, resume and print top, covering the ball and preventing escape?

Why don't print the solid plastic ball in place and have a solid top without pausing anything? 😉
With MMU you could even use different plastic for the ball 😈

I think surface detail may disadvantage that option.... however, a roller, might work!

Go higher in resolution for this layers and the surface might be even beneficial for this purpose. But we think in the same direction 🙂

Yes, I'll do that 🙂

This does not take care about the unloaded filament.
If you want to use this you'll need some buffer for the filament.
It is meant to be a concept.
I am working on a perfect filament buffer, but it is not ready for publishing yet 😉
It needs to be an airtight system and easy to handle.....

wow 😯 ... really looking forward to see the final version. Very impressive. I need this :D. The Prusa solution needs to much space to handle all the filaments and this seems to be very promising to solve that on a reliable way.
Re: One Way Valve for filament (check valve)
There is a new but not final version:
