To put it differently @mkroeker:
We are ENCOURAGING design freedom and making the pricing scheme more FAIR. ;-)
Under the old pricing, low density models were inadvertently encouraged under the old pricing system and (as a designer) this limited most of my designs to low density, wiry things. Now, we have more design freedom.
@Mid7night
The "machine space" pricing model is based on the idea that if you "shrink wrapped" your model, how much space would it take up?
This makes it more precise than bounding box and its more fair - now, instead of paying for the volume of powder you use, you pay for how much space in the machine your model takes up. We then build in, as we always have, how much labor your part takes to clean as reflected by the startup cost, but now it takes into account how many parts there are in your file.
Again, this makes it fair - if you have a five part model, that takes a person cleaning it five times as long as it would to clean one piece - and since we want to treat EVERY model with the same amount of quality and attention, we must reflect this in the price.
