3D-PRINTING
CHUCK HULL: THE FATHER OF 3D PRINTING
WHO SHAPED TECHNOLOGY
• In the early
1980s,3D printer
was founded by
Chuck Hull. Chuck
Hull(75) is the cofounder, executive
vice president and
chief technology
officer of 3D
Systems.
WHAT 3D PRINTING IS:
3D printing or additive manufacturing is a process of making three
dimensional solid objects from a digital file. The creation of a 3D
printed object is achieved using additive processes. In an additive
process an object is created by laying down successive layers of
material until the entire object is created. Each of these layers can
be seen as a thinly sliced horizontal cross-section of the eventual
object.
HOW 3D PRINTING WORKS:
It all starts with making a virtual design of the object you want to
create. This virtual design is made in a CAD(Computer Aided
Design) file using a 3D modeling program (for the creation of a
totally new object) ór with the use of a 3D scanner (to copy an
existing object). This scanner makes a 3D digital copy of an object
and puts it into a 3D modeling program.
To prepare the digital file created in a 3D modeling program for
printing, the software slices the final model into hundreds or
thousands of horizontal layers. When this prepared file is uploaded
in the 3D printer, the printer creates the object layer by layer. The
3D printer reads every slice (or 2D image) and proceeds to create
the object blending each layer together with no sign of the layering
visible, resulting in one three dimensional object.

COST OF 3D PRINTER
The cost of 3D printers has even decreased in the years from 2010
to 2013, with machines generally ranging in price from $20,000 just
three years ago, to less than $1,000 in the current market. Some
printers are even being developed for under $500, making the
technology increasingly available to the average consumer
WHAT CAN 3D PRINTING DO?
-3D Printed Organs-(Future) 3D printing has been used to print
organs from a patient’s own cells. This means that patients may no
longer have to wait a long time for donors in the future. In the past,
hospitals implanted structures into patients made by hands. 3D
printing has drastically improved this process.
Using 3D printing, Dr. Anthony Atala at Wake Forest’s Regenerative
Medicine department was able to create artificial scaffolds in the
shape of an organ with living cells. First the scaffold is printed and
then it is coated with living cells. Now the Regenerative
Department is working on building 3D printers that can print
artificial scaffolds and living cells at the exact same time.
3D Printing In The Automotive
Industry -General Motors -Ford
Motor Company
Urbee 2 Jim Kor and his team of
engineers are building a whole
vehicle with 3D printers called the
Urbee 2. The body of the original
Urbee was made through the use 3D
printing. However, the Urbee 2 as a
whole will be mostly 3D printed. The
Urbee 2 will also look more like a
production-ready car compared to
the original.
3D Printing In The Aerospace Industry Recently, NASA’s rocket
engine injector made from a 3D printer passed a major hot fire test.
In the test, the rocket engine injector generated 10 times more
thrust than any injector made from 3D printing in the past.
3D Printed Gun Defense
Distributed is a high tech
gunsmith group that
created the world’s first fully
open-sourced 3D printed
gun called the “Liberator.”
Fifteen of the gun’s sixteen
parts were made out of 3D
printed plastic and the body
can be etched
overnight. Cody Wilson of
Defense Distributed
believes that the “Liberator”
demonstrates the
governments inability to
enforce gun control.
3D Printing As A Way To Help The Senses
This past summer, Princeton University scientists created a bionic
ear using a 3D printer. The bionic ear can hear much better than
what average human ears can detect. The purpose of this
experiment was to explore an efficient method of merging
electronics with tissues. The scientists created the bionic ear using
the 3D printing of cells and nanoparticles.
THE DREAM OF 3D PRINTED SKIN IS NOW A
REALITY
3-D printer in particular has helped medical science achieve new
breakthroughs. Printing of organs isn’t too far away and soon
enough surgeries will be carried out that will involve transplantation
of 3D printed organs into human body. While the focus is on
printing of organs, a team of researchers is working on printing
skins. Under the leadership of Dr. Sophie Wuerger at University of
Liverpool, U.K., this team is working towards making it possible to
print skin which matches the skin of the individual patient. The idea
is to come up with a way of 3D printing skin which is natural looking
and blends in with the natural skin of the patient. The research is
quite challenging since each individual skin has particular
characteristics and vary from person to person.
