Page 7 - 3D Printing: The Revolution in Personalized Manufacturing

SLS technology 3D prints objects in a bed of powdered material. A laser beam sinters
(heats) or melts certain areas of the powder to build the object layer by layer. As it
is printed, the rest of the powder supports the piece. Manufacturers then use an air
nozzle, a sand blaster, or a simple brush to remove the powder support when the
piece is finished.

Multi jet fusion also falls in the hardener category. First, the
printer deposits a layer of material onto a platform. Then it drops
additional material at thirty million drops per second to build the
object, layer by layer. In some cases, the printer builds multiple
objects at a time. Finally, it fuses the materials and then heats and
cools the object exactly where it needs to make a smooth-edged,
well-defined object.
HP provides this technology to aerospace, automotive,
medical, dental, life sciences, and a variety of other industries.
