An overview of 3D printing technologies
You must have wondered at times, how can houses
or aeroplanes or even complex items can be made
using 3D printing machines. It is a technological
wonder that enables you to practically make or
manufacture anything that crosses your
imagination.

Selective laser sintering(SLS)
This technology is similar to steriolithography,
but uses powdered material in vat in place of
liquid plastic. A roller is used to put a new
layer on the previous layer of powder which is
then laser sintered according to the 3D printing
designs until the required object is made.

Digital Light Processing ( DLP)
This is a similar technology to SLP, but uses a
different light source and uses a LCD display
panel. This technology uses conventional light
sources and micro mirrors to control the light
that falls on surface of the object being
printed. This technology allows large amount of
light to fall on resin, allowing it to harden
quickly.

Fused Deposition Modeling (FDM)
This technology uses production grade
thermoplastics as base material for making
required objects. In this technology,
thermoplastic filaments are melted and extruding
thermoplastic layer by layer till the desired
object is made.
