@Sanjay_Mortimer and I just witnessed the completion of this amazing print - In NinjaFlex!
I honestly never expected this to work but am genuinely amazed by the results. Even though it looks rough - you have to remember that its NinjaFlex.
Just the fact that it hasn’t buckled after 6 hours with what must have been a retract a second means the changes we made have had a big impact on performance…

Yep. Gonna have to get some of this!
Blatant but relevant advertisement, we sell it here: http://e3d-online.com/NinjaFlex-Filament.
There is one less spool in stock because @Sanjay_Mortimer and I stole one… 
Great! Could this material be used for “rubber stamps”?
Yes - it has actually been done before, we have not tried it though…
If you were to print it text-down on something with some texture like blue-tape it would create a good surface for the ink to collect in…
nice!
Great print. How does ninjaflex handle bowden feeds? I’m assuming you ran this on a direct feed
I wonder what those changes were that “had a big impact on performance”.
Lol - cool vid!
