“…We’re elated that 3D printing is gaining
more positive exposure! Help spread the word
by introducing your friends to the
powerful piece of technology…”
By Barack Obama’s, President of US,
12 February 2013, State of the Union Speech
4. The Economist
“Most people probably already own
something that was made with the help of
a 3D printer.”
“Communities offering 3D printing and
other production services that are a bit like
Facebook are already forming online—a
new phenomenon which might be called
social manufacturing.”

10. 3D Printing Application -
Rocket components
NASA engineers 3D printed the engine parts for the Space Launch System (SLS), the vehicle slated
to take human back to the moon.
Technology used: Selective Laser Melting (SLM)
An engine injector made,
With conventional fabrication techniques of molding and welding: In the range of US$250,000
With 3D printing: In the range of US$25,000 (reduced by a factor of 10)
Production times could also dwindle from six months to just weeks.

Robohand
For roughly US$150, the 3-D printed Robohand lets Dylan, who is
missing the fingers on one hand as a result of Amniotic Band
Syndrome, grab things with bendable fingers, which most prosthetic
hands don’t.
Inventors have since provided free Robohands to South African
children, and the open-source design has been downloaded more than
3,500 times in just three months.

using 3D printer Solidscape T76 to create a lost-wax casting mold and then pours gold
to fashion the final piece. Eddie Bakhash, CEO and son of the founder of American
Pearl said "In the old way, jewelers had to spend a lot of hours carving [by hand]. It
would take me two weeks to create that piece. We can do it in a day now.“

28. What is Rapid Tooling?
Rapid Tooling (RT) describes a process that is the result of combining
Rapid Prototyping (RP) techniques with conventional tooling practices
to produce a mold quickly or parts of a functional model from CAD data
in less time and at a lower cost relative to traditional machining
methods.
Rapid
Tooling
Techniques
Indirect methods
use the RP process to
generate an
intermediate physical
model from which the
tooling inserts are
made.

Direct approaches
use a RP-based
process to make
tooling inserts
directly.

30. What is Rapid Manufacturing?
Rapid Manufacturing (RM) is the making of end-use
parts quickly- by any manufacturing method or use of an
additive fabrication process somewhere along the
production chain.
Just the sole of a shoe would
currently require two hours with a
3D printer.

Editor's Notes

Through the phase I ITF project, we have 1) proved the concept of such optical system for assisting the diagnosis of melanoma (skin cancer);
2) Filed a patent for our design
3) One functional prototype + software system
New Balance Selective Laser Sintering (SLS) uses biomechanical data, motion capture, high speed video, sophisticated softwear and embedded sensors to transfer the strides of Olympians and World Champions into precisely what they need to go even faster.
Athletes are measured on a sensitive track to gauge the direction their foot travels whether its forward or back, left or right, and how it moves; 100 sensors are placed on an insert inside the shoe to measure pressure at different points; and a motion capture system — like the ones used for video games and movies — adds stride and broader movement into the equation.
Based on the biomechanical data, researchers printed the spike plates, the part of the shoe that actually connects with the ground, using an SLS 3D printer, and then mated to a standard upper.
All-American runner Jack Bolas became the first to wear a 3D-printed shoe in competition at January’s New Balance Games and now we wait on word for a consumer release. - See more at: http://www.runningshoe-review.com/newbalance/balance-launces-3d-print-shoes/#sthash.aBhWvlO6.dpuf
