Hand:
"With 10,000 miles separating them, two makers designed and built a customizable 3-D-printed prosthetic hand
for a 5-year old boy named Liam in South Africa for $150 in parts. No power necessary."

Ear:
"Scientists at Princeton University have designed a bionic ear that can hear better than human ears.
And get this: It was printed using an off-the-shelf 3D printer"

Kidney:
"Grow your own organs.
Professor Harald Ott and his team at the Ott Lab for Organ Engineering and Regeneration at Harvard University, have been doing just that.
The (very) basic explanation of the technique involves stripping a cadaveric donor organ of its cellular content
leaving the solid structural components, which can be seeded with stem cells to create a recellularised organ...
Print your own organs.
Professor Hagan Bayley and his research group at the University of Oxford think that they have the solution to avoid using stem cells."

Bone:
Kevin Shakeshaff, University of Nottingham in England:
"The tissues of our body are structured at the level of single cells," Shakeshaff said. "Using 3D printing, we can position cells in precise places."

Cast - Künstliches Exoskelett als Gipsverband:
"Passgenaues Nylon-Material, individuell angefertigt aus dem 3D-Drucker, soll den lästigen Gipsverband künftig ablösen.
In Wabenstruktur aufgebaut ist Cortex angeblich nicht nur juckfrei, luftdurchlässig und duschtauglich,
sondern unterstützt auch den herkömmlichen Heilungsprozess"
