3D printers are not your average printer
 They bear little resemblance to today's
document or photo printers,
 They can build objects from scratch—or
rather, from a CAD or 3D scanner file—
out of a variety of materials.

A typical 3D printer is very much like an inkjet printer operated from
a computer
It builds up a 3D model one layer at a time, from the bottom
upward, by repeatedly printing over the same area.
The printer creates a model over a period of hours by turning a 3D
CAD drawing into lots of two-dimensional, cross-sectional layers
Most 3D printers essentially works by extruding molten thermoplastics
(mostly ABS) through a tiny nozzle that it moves around precisely
under computer control.
Is not necessarily need to print in 3D with plastic: in theory, you can
print objects using any molten material that hardens and sets
reasonably quickly
ABS has a whiteish-yellow color in its raw form, but pigments can be
added to make it virtually any color

A new technique has been created
that prints out artificial blood cells
Designed by scientists at Germans'
Fraunhofer Institute
The technique involves printing
artificial biological molecules with a
3-D inkjet printer, and then zapping
the those molecules with a laser
that forms the material into the
shape of blood vessels. Like real
blood vessels, the artificial vessels
have two layers and can form
complex branching structures.
