Volume assumption

hi all,

i calculated volume of a piece. it was 1296.46356 (+/- 1e-06) cubic millimeters which is 17g in 14k gold. but the gold casting came out in 8g.
i don’t know what is the problem…
anyone has the same issue?

Hello - I’d expect about 18 as well at 14g/cc. Is the casting free of voids, can you tell?

It is possible to create a model which has overlapping spaces so that the calculated volume is too high.

i have no idea… because other castings i didn’t make come out similar weights as they expected. is that possible to happen in wax printing?
