The Californian charge towards anything a 3D printer can print now caused UNYQ to open. Weird thing, nothing about this on the website of Fastcompany - usually early to publish what "really" is going on.

From http://www.washingtonpost.com/blogs/innovations/wp/2014/05/07/the-company-thats-determined-to-make-prosthetics-hip-and-stylish/

Eythor Bender wants prosthetic limbs to express the wearer’s personality. So he’s launched UNYQ, which lets customers design their own prosthetic.
“First it’s about mobility, but once you can walk, you care about how does this thing look. If it still looks like a stick it’s not satisfying,” Bender said.
UNYQ offers a blend of stylish models with a unique appearance and contours. With a handful of measurements and four photos of a customer’s existing limb, UNYQ can 3D-print a prosthetic that mirrors the remaining limb with 98 percent accuracy, according to Bender.

This is all very interesting.

However, let us not forget about the overall landscape of prosthetic socket design and, more importantly, prosthetic design [link].
