Hi everybody,

I loaded up a model to shapeways to get an approximately price for it. I want to use the Strong & Flexible Plastic (not dyed, not polished). Shapeways calculated the volume of the model to be 1609,06 cm³ and the price to be 1141,84$.
If i calculate the price myself, my result will be 2252,68$.

Now i hollowed the model to make it cheaper. The volume of the hollowed model is 682,03 cm³ and the price is 956,35$.
I mean the volume is reduced by more than the half, but the price is reduced by only about 15 percent.

I really dont get it how the price is calculated. maybe someone can point me in the right direction.

Measurements of the bounding box: In: 11.6 w x 6.3 d x 8.8 h
Cm: 29.5 w x 16.1 d x 22.3 h

Thanks in advance,

Hank

It is probably because of the density discount:

We also offer a volume and density discount on Strong & Flexible materials. For models that are greater than 10% dense (material volume divided by bounding box volume), after the first 20cm3, the remaining volume is calculated with a 50% discount.
