8. ConclusionWHAT IS 4D PRINTING?
4D printing is a variety of 3D
printing. Basically, 4D printing is a renovation of
3D printing wherein special materials to print
objects that change shape post-production. It is
currently developed by industry leaders and
research facilities like MIT’s Self-Assembly
Lab, Stratasys, and Autodesk.So 4D Printing Is Basically
Just 3D Printing? Then
what’s so Special About
it?HOW IT WORKS? With stratasys, connex technology, a
single print with multi-materials features
can transform from any 1D strand into 3D
shape, 2D surface into 3D shape or more
from 3D shape into another. The connex multi material technology
allows the researchers to program different
material properties into each of the various
particles of the designed geometry and
harnesses the different water-absorbing
properties of the material to activate the self-
assembly process. With water as its activation energy,
this technique promises new possibilities
for embedding programmability and
simple decision making into non
electronics based materials.4D PRINTING: THE TRIGGER
MECHANISMS In 4D printing, you need some stimuli or trigger to
start the transformation. These can include water,
heat, light, electrical currents. There are other forms
of triggers, some of which have to be explored in
depth through research. Of course, you need special
materials that are able to react to these triggers.
Of course, you need special materials that are able to
react to these triggers. It’s making the objects
“programmable” and execute their “genetic code”
whenever you want to have it triggered.4D Printing: Self-Folding Strand into “MIT”

Ongoing Research on 4D Printing There are a variety of examples that truly show how far this
technology has come, from simplistic folding objects to
programmable shape shifting materials and hydrogel
composites. Years of research and testing will eventually lead
to amazing inventions, such as adaptive water pipes and bricks,
self-assembling structures, and even 4d printed soft robots.
The myriad of uses that can come from this technology are
very enticing, so make sure to keep your eye on this new and
engaging industry in the coming years as new developments
facilitate the betterment of our lives in this wonderful world of
tomorrow.OVERVIEW OF 4D OBJECT
