3d Printing Natural Forms III

The third sample series compares a low and high resolution save of the same
model. I created a simple terrain with Bryce Pro using a cauliflower fractal
filter with erosion. When I exported from Bryce, I saved  a low polygon count
.obj file and then a high polygon file.  In preparing the files for printing, I
kept them consistent to ensure  an accurate comparison.

Here is the pertinent data for this test:

Skeinforge settings are the same for both print runs:
Layer thickness: 0.4mm
Perimeter over thickness ratio: 1.55
Infil solidity: 0.1
Feed and flow rate: 40.0mm/s

LOW RESOLUTION SAMPLE
10,712 vertices
21,420 faces

3mm ABS filament / .5mm nozzle
Size: 182mm x 174mm x 43mm

109 layers
149,962 lines
Estimated filament length for print: 37,941mm (41.5 yards)
