Volume and pricing math

    Hi,

    I'm trying to figure out the pricing for large volumes... I uploaded a model of a fairly big head (31x34x45cm), hollow with a relatively thin wall (1cm). Estimated volume came in at just over 5,000cm3 and a cost of 2650 Euro. (I presume it's Euro, even though it has our little Canadian flag next to the symbol... :confused )

    I tried to optimize the model, mainly by making thinner walls, down to 5mm on average. New estimated volume came in at roughly 2,600cm3, but the price dropped only by 150 Euro to 2,500... What gives? I know there is discount pricing for WSF volumes over 20cm3, but the math still does not add up. The thick model seems too cheap and the thin one too expensive... At these scales, a half reduction in volume, should represent a half reduction in cost, no?

    Any thoughts?

    ... and density higher than 10%.

    I guess the density of your thinner variant is less than 10% ...

    ( ( ( 5000cm³ - 20cm³ ) * $1,40 ) / 2 ) + ( 20cm³ * $1,40 ) + $1,50
    = $3486 + $28 + $1,50
    = $3515,50
    --> €2648,57

    Seems correct to me.

    I see... My bad... The 10% density was hard to figure out in there. I understand it refers to 10% of what the total volume would be had it not been hollowed out, correct?

    I think it's 10% of the models bounding box volume.

    But I'll upload a simple test model to be sure about that.
