Actually, this is a matter of privacy.
Your models are printed along with many other buyer's models in the same "build envelope". A single batch of WSF might have 100 or more items inside of it. Other shop owners/buyers may not be willing to publicize their models, and the production team doesn't know which models should be private. I have 200+ models in my public shop, and about 20 that are only available to private patrons. I'm fairly sure that my private patrons would not want their prints publicized before they are ready to go public with their item.
I suggested some time ago that Shapeways should produce specific videos of how each material is printed, and include those videos on the material pages. I believe that it would be well worth the effort to produce a few small batches showing how each material is printed. Having these videos would contribute greatly to the beginning designer's understanding of what is possible and why some prints fail.
I have offered that Shapeways can use any item in my public shop for such videos...
But I wouldn't ask them to produce individual, separate videos of each one of my 200 items, at least not without a
significant video production fee.
