build a prosthetic hand part 2

Today I printed the finger joint hinges using my Airwolf3d v5.5 printer.  I printed them out of FormFutura Flex EcoPLA.  Slicing and printer prep took 10 minutes, the print job itself took 2:22 using a rather slow 30mm/sec print speed.  I printed all 15 pieces in a single print job.  Since they're small pieces, I printed them with a 5mm brim, to help keep them stuck to the print bed.  This worked out really well, and I think these pieces printed a lot cleaner than anything else I've printed with the flexible PLA.  The only other notable configuration change with the flexible PLA is a 4mm retract, which is twice what I use with rigid ABS.  The flex seems to ooze a bit more than rigid plastic.  The extra retraction takes care of this which prevents strings from forming between parts and gives nice clean perimeters.  You can find a good description of extruder ooze and how to prevent it, inthis article at www.slic3r.org
