Hello everyone,


I recently got my hands on an Ender 6 and I'm finally able to use Ninjateks "Ninjaflex" filament which is a super flexy TPU and is used for gaskets and other things.


I made a gasket with it yesterday because I was in a pinch doing a motor rebuild on a sunday, customer needed it on Monday in the morning so I just designed a gasket and printed it with Ninjaflex, it was a for a motor driving some gears and in the gear case there is oil.


Turned out really well, only thing I didn't like was the gasket "squishing" out the sides when I tightened the motor flange, I assume that's because it's just that soft and flexy.


I then called Ninjatek and they recommended Cheetah as it's slightly harder but not as hard as their "Armadillo" which I've also used for a lot of parts.


Does anyone here have experience with Cheetah?

    Cheetah is less flexible than Ninjaflex, but therefore easier to print with a bowden-tube style printer!


    Ninjaflex: Shore Hardness = 85A

    Cheetah:  Shore Hardness = 95A

    Armadillo: Shore Hardness = 75D


    Regular PLA: Shore Hardness = 83D




    How flexible the part you print will be depends on wall thickness, wall layers and of-course infill percentage...

    Cool, thank you for posting that.


    Cheetah sounds like it might just be the thing, Armadillo seems not flexible enough for a lot of things, Ninjaflex way too flexy for most things, so perhaps Cheetah is the happy medium.
