I'm creating a model at the moment, still working on the design. I've uploaded a copy which is about 10cm on it's longest axis.

The cost for the model at 10cm is $ 14.70 WSF, $ 10.21 for sandstone. Which intuitively is correct, because sandstone costs 2/3 for materials, plus the surcharge to start with.

However, if I upscale exactly the same model to 20cm, using the same blender file and exporting it out the cost comparison changes.

The cost for the 20cm model is $ 69.24 WSF, and $ 71.12 for sandstone.

Is there a cost to exceeding a certain scale in sandstone?
I thought sandstone was recommended only for larger scale models?

Or is it a bug in the calculation?
Sandstone should be around $45, assuming the WSF estimate is correct.

WSF and family have some extra pricing rules for big objects that use more than 10% of the bounding box. You'll have to search for that, the materials page lacks it... try the blog.

Assuming you scaled the model by 2 in all three dimensions, the new volume should be 2x2x2=8 times the previous volume, so the sandstone price looks right, and the WSF must be discounted because of the larger size.

Thanks for your replies!
I understand why the cost is different now. Smile

Hey TinBane

I will update the material page asap

but the deal with WSF is:

# On a White, Strong & Flexible model you will then pay the regular $1.50 per cubic cm for any model that is less than 20 cubic cm as well as a start up fee of $1.50 per model.So no change there.
# On White, Strong & Flexible model larger than this you will pay a start up fee of $1.50. You will also pay $1.50 per cubic cm for the first 20 cubic cms. Any additional cubic centimeters are only $0.75 per cubic cm.

Or you could say WSF from 75c percm3* Wink

*plus start up costs

Cheers

Yes you ar right Drscott, we could say that for dense object of more than 20 cm3, you pay a start up cost of $31.50 (for the first 20 cm3) and $0.75/cm3 for any cm3 exceeding the 20 first ones... It is perhaps easier to understand (or isn't it? Smile).


So many things to design, so little time...

It's easier to think of it as a startup of $16.50 + $0.75 per CM3.

Yes, you are right. As long as it is more than 20 cm3 (and has a density of more than 10%, of course).

Found it, Price Reduction Offer. Basically half price for centimeters beyond first 20, if the item is dense.
