NinjaFlex printed “Simple Vase”
Take Away:
Definitely a challenge to print with but the rewards might be worth it depending on your end goals.
The Journey:
It might have taken a day or two worth of fiddling around to get the extruder together on our MakerBot Replicator 2X using MakerBot’s extruder upgrade kit ($8: consists of a spring, bearing and a screw). The instructions for the upgrade on the Makerbot site is for a Replicator 2 (NOT the 2X) and the thickness of the extruder block and how they line up are all different so that was a dead end at first.
I ended up using the Thingiverse extruder files created by 3FPD (our make pic: http://www.thingiverse.com/make:87985) and I finally got the stuff to load without bending and buckling (too much).
Lastly it took a day or two of fiddling with the MakerBot profiles to find the right mix of heat/retraction/speed and so on to get a successful print. (for us it didn’t work with the recommended settings and temps) Above you’ll see some of the prints leading up to the pretty well done Simple Vase print.
