|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?

Thanks for bringing this up. The material page of Strong & Flexible was in error. The price for dyed SLS is $1.78 / cm3 (ex sales tax) and there is a startup fee of $4. White Strong & Flexible is $1.50 / cm3 (ex sales tax) with a startup fee of $1.50.
I hope this clears it up and my apologies for the confusion.
