This is a flexible Ninja figure printed on a Makerbot Replicator with this new flexible TPE filament: http://www.fennerdrives.com/ninjaflex3dprinting/_/3d/ Video: http://www.youtube.com/watch?v=EpkvHo6a888 With the flexible material, I had much better luck after I added the supports. If you use a rigid material like ABS, you can probably go without.Printer info: Makerbot Replicator (original version with the MK8 spring loaded extruder upgrade). Extruder temp: 215 C Platform: Room temp, bare aluminum, glass, or Kapton tape all worked well Standard Replicator settings worked well, but I got the best results after I played with the retraction settings. Retraction Settings (In Skeinforge under Dimension tab): Minimum Travel for Retraction: 1.0mm Retraction Distance: 2.0mm
