The University of Liverpool has developed a different approach to 3D printed skin, which had been previously accomplished. The problem with prior techniques is the appearance: manufactured skin was entirely uniform, without the bumps, wrinkles, freckles and curiosities of actual human skin.
The new approach involves scanning a subject's surviving skin to prepare a way to texture and color the skin in a more representative manner. The technique is also able to match skin under different lighting conditions.
This is, of course, a perfect application for 3D printing technology: a custom, one-time, highly personalized object is manufactured.
It's so personalized it's actually part of you.
