Still dialing in the material, obviously, but not a bad first attempt at either, I think.
Where did you get PP filament? I have been dying to try some but was told it doesn't exist due to layer adhesion issues... :confused:
Sebastian,
I don't know where we got ours, but I was able to search and find three suppliers in about 90 seconds:

The layers do not appear to have any adhesion issues. I flex this thing all the time to show people during skype sessions.
so what advantages/disadvantages do the two materials have ?
PP is very flexible, but not very compressible - it bends (less bendy than ninjaflex) but doesn't smoosh (less smooshy than ninjaflex). And it has a stronger force than ninjaflex to return to its original configuration.
Below are some results from this weekend's testing of the MK1-350, dialing in PC temps between 305 and 325:
