The 3rd Industrial revolution
The 1st Industrial revolution (1760~1840)
~ the transition to new manufacturing processes
(from hand production methods to machines)
~ steam power and machine tools
The 2nd Industrial revolution (1867~1914)
~ Technical Revolution (mass production and
~ electricity, internal combustion engine, new
materials and substances (alloys, chemicals), and
communication tech (telegraph, radio)
The 3rd Industrial revolution (1984~ )
~ additive process distinct from traditional
machining techniques (subtractive processes,
material removal by cutting or drilling)
~ 3D printer
World tend of 3D printing
Microsoft adds 3D printing support to
Windows 8.1. Jun. 26, 2013.
3D printers soon in Microsoft stores.
UK kids to be taught 3D printing and
robotics from age of 5 from 2014. (July 4, 2013)
Obama's speech highlights rise of
3D printing (additive manufacturing)
US President Obama highlighted 3D printing
as new high-tech jobs in US. (February 13, 2013)
3D printing technology can be moved from the
research phase to day-to-day use.
As tech-obsessed novelty, 3D printing has been
used successfully for various tasks, such as
making jewelry, medical supplies, or larger
projects in industrial design and engineering.
The World's Top 10 Most Innovative
Companies in Consumer Electronics
1. Apple (has announced it will begin
manufacturing some of its iMacs in 3D printing
in US in 2013)
9. MakerBot released Replicator 2 for
transforming the 3D printer from experiment
to home-office appliance in 2012.

Goals for the future
IBM making 3D construction more efficient
in both cost and time.
Establishing a platform to store, display, and
exchange 3D models.
Create business opportunities for all parties
through collaboration for various tasks and
Expanding 3D applications through join
research with international partners.
