3D Printed Human Skin

In news:

  • Researchers at the IIT-Delhi have successfully 3D bio-printed human skin models that have certain anatomically relevant structural, mechanical and biochemical features similar to native human skin.
  • The bio-printed skin model will have wide applications in testing cosmetics. It can also reduce and probably even replace testing on animals.
  • The study was funded by ITC Ltd.

About 3D printing:

  • 3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file, for instance a CAD (Computer Aided Design) file.
  • In an additive process an object is created by laying down successive layers of material until the object is created.
  • It allows producing complex (functional) shapes using less material than traditional manufacturing methods.
  • It is used in manufacturing, medical, industry and sociocultural sectors.
  • Recently, Scientists at Tel Aviv University in Israel unveiled a 3D print of a heart with human tissue and vessels.
