|Dyed SLS pricing model [message #8051] Thu, 03 December 2009 17:37 UTC
Yay! Black SLS. Thanks a lot!|
I believe the pricing model for the dyed SLS is wrong.
I tried a simple test model. It costs $298.87 in white and $249.63 in black SLS, inc VAT.
This is on the material page:
"The price per dyed model is $4 start up costs and $ 1.50 per cubic centimeter of material you use for your model."
So that's $4 startup and $1.5 per CM3, compared to $1.50 startup and 1.5 per cm3.
Now, acknowledging I pay 19% sales tax, the following should be valid:
1.19*(4+1.5x)=298.87 and 1.19*(1.5+1.5x)=249.63
But in fact, it is not. The latter equation gives x=139, the first gives x=165. Where does this 30 cm3 worth of printing material go?
I think I found the answer. The dyed models are being taxed twice:
This equation solves to x=139, which is good.
Contrary to the material info page, in the newsletter a cost of $1.78 per cm3 is mentioned.
This $1.78 is equal to the $1.50 with 19% tax added.
What is going on? Is the newsletter correct and is the materials page wrong or is it the other way around?
