5. HOW DOES 3D PRINTER WORKS?
3D printing is a process of making three dimensional sol id
objects from a digital fi le.
The creation of a 3D printer object is achieved using additive
processes
An object is created by laying down successive layers of
material unti l the entire object is created

11. HISTORY OF 3D PRINTING
In the history of manufacturing, subtractive methods have
of ten come first. The province of machining was generally a
subtractive af fair, from fi l ing and turning through mi l ing and
grinding.
Ad d it ive ma n u f ac t urin g ’ s e a r l ie s t a p p lic at io n s h ave b e e n o n
the toolroom end of the manufacturing spectrum.
However, as the years go by and technology continually
advances, additive methods are moving even fur ther into the
production end of manufacturing.
12. HOW IS IT BEING USED TO MAKE TOOLS?
In 2007 the use of 3D printing technology for ar tistic
expression was suggested. Ar tist have been using 3D printers
in various ways
In 2010 3D printing technology was being studied by
biotechnology firms and academia for possible use in tissue
engineering appl ications where organs and body par ts are
bui lt using inkjet techniques.
13. POSSIBILITIES IN THE FUTURE
This technological development wi l l change the nature of
commerce, because users wi l l be able to do their own
manufacturing rather than spending money to buy products
from other people.
3D printers with various colors and materials are already exist
and it wi l l probably have more choices for users to choose in
the future.

A team of engineer s assembled the par t s to make the car roadwor thy f rom pieces
pr inted out . The ent i re process took 44 hour s, star t to f inish, and was done in f ront

The body, seat s, and major components were 3D pr inted in a process cal led di rect

were al so not 3D pr inted. That said, the St rat i uses far less par t s than a
convent ional car - -about 40 compared to the tens of thousands on a product ion

The idea behind the creat ion of thi s unique 3D vehicle i s to show the v iabi l i ty of
thi s kind of technology and to prove that i t has a place in the automot ive indust r y.
