2. What is 3D Printing?
 3D printing is a process of making a three-dimensional solid
object of virtually any shape from a digital model.
 Also known as Additive Manufacturing or Rapid Prototyping.
 It is an additive process where materials are laid down as layer
by layer in different shapes of thickness ranging from
0.0254mm to 1mm to make 3D objects.
 This technology uses a 3D Printing machine connected to a
computer containing digital image/data of the object (to be
printed) for the printing purpose.

3. History
 1984-The technology for printing physical 3D objects from digital
data(Stereo lithography) was first developed by Charles Hull.
 1986 - Charles Hull founded 3D Systems and developed the first
commercial 3D Printing machine, it was called as Stereolithography
Apparatus.
 1988 - Scott Crump invented Fused Deposition Modeling (FDM).
 1993 - Massachusetts Institute of Technology (MIT) patented "3
Dimensional Printing techniques".

6. Types of Printing
 Stereolithography: It is an additive manufacturing process using
liquid UV-curable photopolymer “resin” and a UV laser to build parts
a layer at a time.
 Fused deposition modeling (FDM): It is an additive manufacturing
which uses hot semi-liquid extrude directly to print objects.
 Laminated object manufacturing(LOM) : In this, layers of adhesive-
coated paper, plastic or metal laminates are successively glued
together and cut to shape with a knife or laser cutter.
 Selective laser sintering (SLS): an additive manufacturing technique
that uses a high power laser (eg:-, CO2 laser) to fuse small particles
of plastic, metal , ceramic or glass powders into a mass that has a
desired 3-dimensional shape.
