1
00:00:00,951 --> 00:00:04,660
My grandfather was a cobbler.

2
00:00:04,660 --> 00:00:07,899
Back in the day, he made custom-made shoes.

3
00:00:07,899 --> 00:00:10,110
I never got to meet him.

4
00:00:10,110 --> 00:00:12,910
He perished in the Holocaust.

5
00:00:12,910 --> 00:00:16,988
But I did inherit his love for making,

6
00:00:16,988 --> 00:00:20,926
except that it doesn't exist that much anymore.

7
00:00:20,926 --> 00:00:23,436
You see, while the Industrial Revolution

8
00:00:23,436 --> 00:00:26,179
did a great deal to improve humanity,

9
00:00:26,179 --> 00:00:29,116
it eradicated the very skill

10
00:00:29,116 --> 00:00:32,136
that my grandfather loved,

11
00:00:32,136 --> 00:00:35,437
and it atrophied craftsmanship as we know it.

12
00:00:35,437 --> 00:00:40,740
But all of that is about to change with 3D printing,

13
00:00:40,740 --> 00:00:45,818
and it all started with this,

14
00:00:45,818 --> 00:00:47,650
the very first part

15
00:00:47,650 --> 00:00:49,910
that was ever printed.

16
00:00:49,910 --> 00:00:52,473
It's a little older than TED.

17
00:00:52,473 --> 00:00:55,120
It was printed in 1983

18
00:00:55,120 --> 00:00:57,840
by Chuck Hull,

19
00:00:57,840 --> 00:01:01,448
who invented 3D printing.

20
00:01:01,448 --> 00:01:03,631
But the thing that I want to talk to you about today,

21
00:01:03,631 --> 00:01:05,561
the big idea that I want to discuss with you,

22
00:01:05,561 --> 00:01:07,464
is not that 3D printing

23
00:01:07,464 --> 00:01:10,724
is going to catapult us into the future,

24
00:01:10,724 --> 00:01:13,120
but rather that it's actually going

25
00:01:13,120 --> 00:01:16,213
to connect us with our heritage,

26
00:01:16,213 --> 00:01:19,237
and it's going to usher in a new era

27
00:01:19,237 --> 00:01:23,121
of localized, distributed manufacturing

28
00:01:23,121 --> 00:01:24,853
that is actually based

29
00:01:24,853 --> 00:01:27,312
on digital fabrication.

30
00:01:27,312 --> 00:01:33,110
So think about useful things.

31
00:01:33,110 --> 00:01:34,953
You all know your shoe size.

32
00:01:34,953 --> 00:01:36,631
How many of you know the size

33
00:01:36,631 --> 00:01:38,116
of the bridge of your nose

34
00:01:38,116 --> 00:01:41,379
or the distance between your temples?

35
00:01:41,379 --> 00:01:43,910
Anybody?

36
00:01:43,910 --> 00:01:45,708
Wouldn't it be awesome if you could,

37
00:01:45,708 --> 00:01:47,980
for the first time, get eyewear

38
00:01:47,980 --> 00:01:51,190
that actually fits you perfectly

39
00:01:51,190 --> 00:01:54,865
and doesn't require any hinge assembly,

40
00:01:54,865 --> 00:01:58,422
so chances are, the hinges are not going to break?

41
00:01:58,422 --> 00:02:01,020
But the implications of 3D printing

42
00:02:01,020 --> 00:02:04,477
go well beyond the tips of our noses.

43
00:02:04,477 --> 00:02:06,805
When I met Amanda for the first time,

44
00:02:06,805 --> 00:02:09,400
she could already stand up and walk a little bit

45
00:02:09,400 --> 00:02:12,355
even though she was paralyzed from the waist down,

46
00:02:12,355 --> 00:02:15,070
but she complained to me that her suit

47
00:02:15,070 --> 00:02:16,995
was uncomfortable.

48
00:02:16,995 --> 00:02:18,446
It was a beautiful robotic suit

49
00:02:18,446 --> 00:02:20,134
made by Ekso Bionics,

50
00:02:20,134 --> 00:02:23,902
but it wasn't inspired by her body.

51
00:02:23,902 --> 00:02:26,219
It wasn't made to measure.

52
00:02:26,219 --> 00:02:28,942
So she challenged me to make her something

53
00:02:28,942 --> 00:02:32,103
that was a little bit more feminine,

54
00:02:32,103 --> 00:02:35,331
a little bit more elegant,

55
00:02:35,331 --> 00:02:36,585
and lightweight,

56
00:02:36,585 --> 00:02:38,117
and like good tailors,

57
00:02:38,117 --> 00:02:42,497
we thought that we would measure her digitally.

58
00:02:42,497 --> 00:02:45,586
And we did. We built her an amazing suit.

59
00:02:45,586 --> 00:02:48,594
The incredible part about what I learned

60
00:02:48,594 --> 00:02:51,744
from Amanda is a lot of us are looking at 3D printing

61
00:02:51,744 --> 00:02:53,442
and we say to ourselves,

62
00:02:53,442 --> 00:02:56,300
it's going to replace traditional methods.

63
00:02:56,300 --> 00:02:58,280
Amanda looked at it and she said,

64
00:02:58,280 --> 00:03:00,170
it's an opportunity for me

65
00:03:00,170 --> 00:03:02,375
to reclaim my symmetry

66
00:03:02,375 --> 00:03:05,353
and to embrace my authenticity.

67
00:03:05,353 --> 00:03:07,482
And you know what? She's not standing still.

68
00:03:07,482 --> 00:03:10,283
She now wants to walk in high heels.

69
00:03:12,940 --> 00:03:14,339
It doesn't stop there.

70
00:03:14,339 --> 00:03:17,290
3D printing is changing

71
00:03:17,290 --> 00:03:20,641
personalized medical devices as we know them,

72
00:03:20,641 --> 00:03:25,086
from new, beautiful, conformal,

73
00:03:25,086 --> 00:03:28,167
ventilated scoliosis braces

74
00:03:28,167 --> 00:03:31,529
to millions of dental restorations

75
00:03:31,529 --> 00:03:35,026
and to beautiful bracings

76
00:03:35,026 --> 00:03:38,189
for amputees,

77
00:03:38,189 --> 00:03:41,361
another opportunity to emotionally reconnect

78
00:03:41,361 --> 00:03:43,881
with your symmetry.

79
00:03:43,881 --> 00:03:46,332
And as we sit here today,

80
00:03:46,332 --> 00:03:49,179
you can go wireless on your braces

81
00:03:49,179 --> 00:03:51,260
with clear aligners,

82
00:03:51,260 --> 00:03:53,399
or your dental restorations.

83
00:03:53,399 --> 00:03:55,591
Millions of in-the-ear hearing aids

84
00:03:55,591 --> 00:03:58,358
are already 3D printed today.

85
00:03:58,358 --> 00:04:00,723
Millions of people are served today

86
00:04:00,723 --> 00:04:03,419
from these devices.

87
00:04:03,419 --> 00:04:07,179
What about full knee replacements,

88
00:04:07,179 --> 00:04:10,246
from your data, made to measure,

89
00:04:10,246 --> 00:04:14,708
where all of the tools and guides are 3D printed?

90
00:04:14,708 --> 00:04:18,216
G.E. is using 3D printing

91
00:04:18,216 --> 00:04:20,894
to make the next generation LEAP engine

92
00:04:20,894 --> 00:04:24,590
that will save fuel to the tune

93
00:04:24,590 --> 00:04:27,306
of about 15 percent

94
00:04:27,306 --> 00:04:29,498
and cost for an airline

95
00:04:29,498 --> 00:04:31,893
of about 14 million dollars.

96
00:04:31,893 --> 00:04:33,575
Good for G.E., right?

97
00:04:33,575 --> 00:04:36,108
And their customers and the environment.

98
00:04:36,108 --> 00:04:38,568
But, you know, the even better news

99
00:04:38,568 --> 00:04:41,799
is that this technology is no longer reserved

100
00:04:41,799 --> 00:04:44,465
for deep-pocketed corporations.

101
00:04:44,465 --> 00:04:47,700
Planetary Resources, a startup

102
00:04:47,700 --> 00:04:49,194
for space explorations

103
00:04:49,194 --> 00:04:53,750
is going to put out its first 
space probe later this year.

104
00:04:53,750 --> 00:04:57,200
It was a fraction of a NASA spaceship,

105
00:04:57,200 --> 00:05:00,669
it costs a fraction of its cost,

106
00:05:00,669 --> 00:05:04,360
and it's made with less than a dozen moving parts,

107
00:05:04,360 --> 00:05:08,039
and it's going to be out in space later this year.

108
00:05:08,039 --> 00:05:11,402
Google is taking on this very audacious project

109
00:05:11,402 --> 00:05:14,104
of making the block phone, the Ara.

110
00:05:14,104 --> 00:05:16,617
It's only possible because of the development

111
00:05:16,617 --> 00:05:19,166
of high-speed 3D printing that for the first time

112
00:05:19,166 --> 00:05:23,526
will make functional, usable modules

113
00:05:23,526 --> 00:05:24,922
that will go into it.

114
00:05:24,922 --> 00:05:28,220
A real moonshot, powered by 3D printing.

115
00:05:28,220 --> 00:05:30,768
How about food?

116
00:05:30,768 --> 00:05:33,292
What if we could, for the first time,

117
00:05:33,292 --> 00:05:36,279
make incredible delectables

118
00:05:36,279 --> 00:05:41,000
like this beautiful TED Teddy here,

119
00:05:41,000 --> 00:05:42,826
that are edible?

120
00:05:42,826 --> 00:05:46,510
What if we could completely
change the experience,

121
00:05:46,510 --> 00:05:50,315
like you see with that absinthe serving

122
00:05:50,315 --> 00:05:54,065
that is completely 3D printed?

123
00:05:54,065 --> 00:05:58,868
And what if we could begin to put ingredients

124
00:05:58,868 --> 00:06:02,309
and colors and flavors in every taste,

125
00:06:02,309 --> 00:06:05,107
which means not only delicious foods

126
00:06:05,107 --> 00:06:08,924
but the promise of personalized nutrition

127
00:06:08,924 --> 00:06:10,278
around the corner?

128
00:06:10,278 --> 00:06:13,423
And that gets me to one of the
biggest deals about 3D printing.

129
00:06:13,423 --> 00:06:16,284
With 3D printing, complexity is free.

130
00:06:16,284 --> 00:06:19,146
The printer doesn't care

131
00:06:19,146 --> 00:06:21,790
if it makes the most rudimentary shape

132
00:06:21,790 --> 00:06:23,990
or the most complex shape,

133
00:06:23,990 --> 00:06:27,148
and that is completely turning design

134
00:06:27,148 --> 00:06:30,694
and manufacturing on its head as we know it.

135
00:06:30,694 --> 00:06:33,021
Many people think that 3D printing will be

136
00:06:33,021 --> 00:06:36,759
the end of manufacturing as we know it.

137
00:06:36,759 --> 00:06:39,272
I think that it's the opportunity to put

138
00:06:39,272 --> 00:06:42,933
tomorrow's technology in the hands of youngsters

139
00:06:42,933 --> 00:06:45,536
that will create endless abundance

140
00:06:45,536 --> 00:06:47,456
of job opportunities,

141
00:06:47,456 --> 00:06:49,420
and with that,

142
00:06:49,420 --> 00:06:52,314
everybody can become an expert maker

143
00:06:52,314 --> 00:06:54,418
and an expert manufacturer.

144
00:06:54,418 --> 00:06:56,304
That will take new tools.

145
00:06:56,304 --> 00:06:59,037
Not everybody knows how to use CAD,

146
00:06:59,037 --> 00:07:01,080
so we're developing haptics,

147
00:07:01,080 --> 00:07:03,019
perceptual devices

148
00:07:03,019 --> 00:07:04,920
that will allow you to touch

149
00:07:04,920 --> 00:07:06,685
and feel your designs

150
00:07:06,685 --> 00:07:09,563
as if you play with digital clay.

151
00:07:09,563 --> 00:07:11,260
When you do things like that,

152
00:07:11,260 --> 00:07:13,263
and we also developed things that take

153
00:07:13,263 --> 00:07:15,817
physical photographs that are instantly printable,

154
00:07:15,817 --> 00:07:18,467
it will make it easier to create content,

155
00:07:18,467 --> 00:07:21,498
but with all of the unimagined,

156
00:07:21,498 --> 00:07:23,890
we will also have the unintended,

157
00:07:23,890 --> 00:07:29,166
like democratized counterfeiting

158
00:07:29,166 --> 00:07:32,150
and ubiquitous illegal possession.

159
00:07:32,150 --> 00:07:33,633
So many people ask me,

160
00:07:33,633 --> 00:07:36,141
will we have a 3D printer in every home?

161
00:07:36,141 --> 00:07:38,394
I think it's the wrong question to ask.

162
00:07:38,394 --> 00:07:39,775
The right question to ask is,

163
00:07:39,775 --> 00:07:43,540
how will 3D printing change my life?

164
00:07:43,540 --> 00:07:45,730
Or, in other words, what room in my house

165
00:07:45,730 --> 00:07:47,894
will 3D printing fit in?

166
00:07:47,894 --> 00:07:49,890
So everything that you see here

167
00:07:49,890 --> 00:07:52,001
has been 3D printed,

168
00:07:52,001 --> 00:07:55,080
including these shoes

169
00:07:55,080 --> 00:07:57,322
at the Amsterdam fashion show.

170
00:07:57,322 --> 00:08:01,018
Now, these are not my grandfather's shoes.

171
00:08:01,018 --> 00:08:02,710
These are shoes that represent

172
00:08:02,710 --> 00:08:04,908
the continuation of his passion

173
00:08:04,908 --> 00:08:07,288
for hyper-local manufacturing.

174
00:08:07,288 --> 00:08:12,531
My grandfather didn't get to see Nike

175
00:08:12,531 --> 00:08:17,080
printing cleats for the recent Super Bowl,

176
00:08:17,080 --> 00:08:20,487
and my father didn't get to see me standing

177
00:08:20,487 --> 00:08:23,597
in my hybridized 3D printed shoes.

178
00:08:23,597 --> 00:08:26,348
He passed away three years ago.

179
00:08:26,348 --> 00:08:29,591
But Chuck Hull, the man that invented it all,

180
00:08:29,591 --> 00:08:31,960
is right here in the house today,

181
00:08:31,960 --> 00:08:33,742
and thanks to him,

182
00:08:33,742 --> 00:08:36,460
I can say, thanks to his invention, I can say

183
00:08:36,460 --> 00:08:38,437
that I am a cobbler too,

184
00:08:38,437 --> 00:08:40,891
and by standing in these shoes

185
00:08:40,891 --> 00:08:43,225
I am honoring my past

186
00:08:43,225 --> 00:08:45,377
