I have had this problem in two different technology selector programs.
One was in DERP, which is an EU-supportet work, which has resulted in a
selector for materials and technolgies including vacuum casting and layer
manufacturing processess.
The other case is a Swedish projekt with a selector for RP process chains.
For both selectors we choosed not to involve a mathematical scale, but
defined different type of complexity by a few examples showed with pictures,
and the operator could choose the picture that best correspond to his own
part complexity.

Ämne: Part Complexity on the SLA
Greetings RPML,
I am wondering if anyone has any ideas on how to numerically categorize part
complexity for building parts on the SLA. I am trying to place parts into
three groups of complexity: low, medium, and high. Visually, I have the
ability to categorize the parts with respect to how they will be built on
the
SLA. However, mathematically I am running into trouble. I have analyzed
ratios between 1. surface area and extent volume, 2. surface area and part
volume, and 3. part volume and support volume. Unfortunately, no trends are
developing.
Any help that you can provide will be greatly appreciated. Again I am
considering the part complexity under the assumption that it will be built
on
the SLA.
Thank you in advance,
