Ninjatek Cheetah

[Oliveros 11]

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?

I have some experience with Ninjatek Cheetah, but not in the way you used Ninjaflex (gasket)...

Okay, what's your experience with it?

 

Is it as flexible as Ninjaflex or as hard as Armadillo?

 

Just trying to get a feel for it.

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.
