• The first industrial

revolution “began in

Britain in the late 18th

century, with the

mechanisation of the

textile industry.

36

First Industrial Revolution

• The “second industrial

revolution came in the

early 20th century, when

Henry Ford mastered the

moving assembly line

and ushered in the age of

mass production.” The

Second Industrial Revolution

Next Industrial Revolution !!3D Printing Technology!!

40

1984

Charles Hull developed the first 3D printer and named the technique as Stereo lithography.

Later 1990’s

Other Companies developed 3d printer’s.

2005

Z Corp launched first high

definition color 3D printer.

41

How does the 3D printer come from??

Types of Printing materials

Types of 3D Printers

Function of 3D Scanner

3D Printing software, and progress

Recent appliance

42

3D Printing Technology involves….

Reading the .stl file in 3D software

Slicing the objects to make each build layer

Evaluating 2D geometry outlines

Generating cross-hatch

infill

Arc compensation

Translate the tool path to G

code

43

44

3D printing materials Usually print with plastic filaments, likes:

ABS (220 – 240C) – Strong and last long, bad smell during printing PLA (180 – 200C) – Made from corn, bio degradable PVA (220 – 240C) – Water soluble, uses to print ‘supports’

49

Fused Deposition Modeling (FDM)

FDM uses a reel of plastic filament

and extruding it through a small

diameter nozzle and fused together

to form objects.

50

Stereolithography (SLA)

SLA uses a laser and a set of

mirrors to solidify the

layer of UV light curable

resin.

Since laser beam is narrow

enough, output quality is

better than FDM.

51

Selective Laser Sintering (SLS)

SLS uses a laser to melt the

selected metal / polymer

powder and form a physical

object.

This method usually uses

building metal objects.

52

Binder jetting / Polymer jetting

Binder jetting uses liquid

adhesive to binding the

selected polymer powder

to form a physical object.

With colour adhesive, it

can form colour objects.

How 3D Printing Can Change the world?

• Adopted 3D printing as a way to increase

innovation

• Reduce costs and speed up the process

• 3D models of buildings can be easily created

and edited as plans develop – something that

used to take a significant amount of time to

make

66

Advanced Manufacturing

• Airbus would make a 3D printer that is large enough to make planes from the ground up – a hangar-size printer as large as 80m x 80m.

• NASA has been looking at 3D printing for some time now, and considering the technology for long missions where astronauts could create their own equipment during the trip.

67

Advanced Manufacturing

68

69

• Custom hearing aids and braces.

• Body parts, including ears, hips and even organs, in exact proportions to fit the patient.

• In February 2012, surgeons successfully implanted an entire titanium jaw, made with 3D printing, in an elderly woman.
