Well, it's an oldie but a goodie. I remember it when I hopped on at SU v6.

Greenace92.................what happened to you? You piqued my curiosity with your Q.....and no report back I have done a few "full" scale print runs myself with good success and wondering if you needed any further guidance? Just checking..... Charlie

You should be able to calculate the volume, and the maths to work out the weight given the material type and density should be straightforward.

Hi Green Ace, When did you register your previous (disappeared) account? Anyway, back to your problem: could you show us some exmples? Edit: just as a "teaser", have a look at this topic in the gallery. It also started from some 2D views of the model (although certainly went quite far from simply building the basic mesh).
