Yoga interrupted

My third and final sculpture this week is a mashup of two more photos I found on Belladonna's Tumblr blog. I wanted to use the top half of this photo ...

... and the bottom half of this painting by Giuseppe Gigli ...

... combined in a single pose.

Getting the feet into position was the most difficult part.

I am already a total convert to the idea of 'micro-layering - printing the external skin at 0.1 mm layer height but the support and infill at 0.3 mm layer height, so infill is only laid down every third layer. One of the new features I have been experimenting with is 'infill zoning'.
  • Starting at the bottom, Zone 1 uses 25% infill.
  • The top surfaces of the calves, thighs and feet are in Zone 2 and use 40% infill.
  • The trunk, arms and head in Zone 3 revert to 25% infill.
  • The top of the head uses 50% infill.

You can just about see the four zones in this reverse cross-section view (click to enlarge).

This uses less infill material where it is not needed, saving time and money, but increases the level of internal support where important top surfaces need to be laid down smoothly. 

The support material generated by Simplify3D worked reasonably well but left the undersides of the elbows and calves a little rougher than I would have liked.
