My grandfather was a cobbler.
0
12951
3709
00:16
Back in the day, he made custom-made shoes.
1
16660
3239
00:19
I never got to meet him.
2
19899
2211
00:22
He perished in the Holocaust.
3
22110
2800
00:24
But I did inherit his love for making,
4
24910
4078
00:28
except that it doesn't exist that much anymore.
5
28988
3938
00:32
You see, while the Industrial Revolution
6
32926
2510
00:35
did a great deal to improve humanity,
7
35436
2743
00:38
it eradicated the very skill
8
38179
2937
00:41
that my grandfather loved,
9
41116
3020
00:44
and it atrophied craftsmanship as we know it.
10
44136
3301
00:47
But all of that is about to change with 3D printing,
11
47437
5303
00:52
and it all started with this,
12
52740
5078
00:57
the very first part
13
57818
1832
00:59
that was ever printed.
14
59650
2260
01:01
It's a little older than TED.
15
61910
2563
01:04
It was printed in 1983
16
64473
2647
01:07
by Chuck Hull,
17
67120
2720
01:09
who invented 3D printing.
18
69840
3608
01:13
But the thing that I want to talk to you about today,
19
73448
2183
01:15
the big idea that I want to discuss with you,
20
75631
1930
01:17
is not that 3D printing
21
77561
1903
01:19
is going to catapult us into the future,
22
79464
3260
01:22
but rather that it's actually going
23
82724
2396
01:25
to connect us with our heritage,
24
85120
3093
01:28
and it's going to usher in a new era
25
88213
3024
01:31
of localized, distributed manufacturing
26
91237
3884
01:35
that is actually based
27
95121
1732
01:36
on digital fabrication.
28
96853
2459
01:39
So think about useful things.
29
99312
5798
01:45
You all know your shoe size.
30
105110
1843
01:46
How many of you know the size
31
106953
1678
01:48
of the bridge of your nose
32
108631
1485
01:50
or the distance between your temples?
33
110116
3263
01:53
Anybody?
34
113379
2531
01:55
Wouldn't it be awesome if you could,
35
115910
1798
01:57
for the first time, get eyewear
36
117708
2272
01:59
that actually fits you perfectly
37
119980
3210
02:03
and doesn't require any hinge assembly,
38
123190
3675
02:06
so chances are, the hinges are not going to break?
39
126865
3557
02:10
But the implications of 3D printing
40
130422
2598
02:13
go well beyond the tips of our noses.
41
133020
3457
02:16
When I met Amanda for the first time,
42
136477
2328
02:18
she could already stand up and walk a little bit
43
138805
2595
02:21
even though she was paralyzed from the waist down,
44
141400
2955
02:24
but she complained to me that her suit
45
144355
2715
02:27
was uncomfortable.
46
147070
1925
02:28
It was a beautiful robotic suit
47
148995
1451
02:30
made by Ekso Bionics,
48
150446
1688
02:32
but it wasn't inspired by her body.
49
152134
3768
02:35
It wasn't made to measure.
50
155902
2317
02:38
So she challenged me to make her something
51
158219
2723
02:40
that was a little bit more feminine,
52
160942
3161
02:44
a little bit more elegant,
53
164103
3228
02:47
and lightweight,
54
167331
1254
02:48
and like good tailors,
55
168585
1532
02:50
we thought that we would measure her digitally.
56
170117
4380
02:54
And we did. We built her an amazing suit.
57
174497
3089
02:57
The incredible part about what I learned
58
177586
3008
03:00
from Amanda is a lot of us are looking at 3D printing
59
180594
3150
03:03
and we say to ourselves,
60
183744
1698
03:05
it's going to replace traditional methods.
61
185442
2858
03:08
Amanda looked at it and she said,
62
188300
1980
03:10
it's an opportunity for me
63
190280
1890
03:12
to reclaim my symmetry
64
192170
2205
03:14
and to embrace my authenticity.
65
194375
2978
03:17
And you know what? She's not standing still.
66
197353
2129
03:19
She now wants to walk in high heels.
67
199482
2801
03:24
It doesn't stop there.
68
204940
1399
03:26
3D printing is changing
69
206339
2951
03:29
personalized medical devices as we know them,
70
209290
3351
03:32
from new, beautiful, conformal,
71
212641
4445
03:37
ventilated scoliosis braces
72
217086
3081
03:40
to millions of dental restorations
73
220167
3362
03:43
and to beautiful bracings
74
223529
3497
03:47
for amputees,
75
227026
3163
03:50
another opportunity to emotionally reconnect
76
230189
3172
03:53
with your symmetry.
77
233361
2520
03:55
And as we sit here today,
78
235881
2451
03:58
you can go wireless on your braces
79
238332
2847
04:01
with clear aligners,
80
241179
2081
04:03
or your dental restorations.
81
243260
2139
04:05
Millions of in-the-ear hearing aids
82
245399
2192
04:07
are already 3D printed today.
83
247591
2767
04:10
Millions of people are served today
84
250358
2365
04:12
from these devices.
85
252723
2696
04:15
What about full knee replacements,
86
255419
3760
04:19
from your data, made to measure,
87
259179
3067
04:22
where all of the tools and guides are 3D printed?
88
262246
4462
04:26
G.E. is using 3D printing
89
266708
3508
04:30
to make the next generation LEAP engine
90
270216
2678
04:32
that will save fuel to the tune
91
272894
3696
04:36
of about 15 percent
92
276590
2716
04:39
and cost for an airline
93
279306
2192
04:41
of about 14 million dollars.
94
281498
2395
04:43
Good for G.E., right?
95
283893
1682
04:45
And their customers and the environment.
96
285575
2533
04:48
But, you know, the even better news
97
288108
2460
04:50
is that this technology is no longer reserved
98
290568
3231
04:53
for deep-pocketed corporations.
99
293799
2666
04:56
Planetary Resources, a startup
100
296465
3235
04:59
for space explorations
101
299700
1494
05:01
is going to put out its first space probe later this year.
102
301194
4556
05:05
It was a fraction of a NASA spaceship,
103
305750
3450
05:09
it costs a fraction of its cost,
104
309200
3469
05:12
and it's made with less than a dozen moving parts,
105
312669
3691
05:16
and it's going to be out in space later this year.
106
316360
3679
05:20
Google is taking on this very audacious project
107
320039
3363
05:23
of making the block phone, the Ara.
108
323402
2702
05:26
It's only possible because of the development
109
326104
2513
05:28
of high-speed 3D printing that for the first time
110
328617
2549
05:31
will make functional, usable modules
111
331166
4360
05:35
that will go into it.
112
335526
1396
05:36
A real moonshot, powered by 3D printing.
113
336922
3298
05:40
How about food?
114
340220
2548
05:42
What if we could, for the first time,
115
342768
2524
05:45
make incredible delectables
116
345292
2987
05:48
like this beautiful TED Teddy here,
117
348279
4721
05:53
that are edible?
118
353000
1826
05:54
What if we could completely change the experience,
119
354826
3684
05:58
like you see with that absinthe serving
120
358510
3805
06:02
that is completely 3D printed?
121
362315
3750
06:06
And what if we could begin to put ingredients
122
366065
4803
06:10
and colors and flavors in every taste,
123
370868
3441
06:14
which means not only delicious foods
124
374309
2798
06:17
but the promise of personalized nutrition
125
377107
3817
06:20
around the corner?
126
380924
1354
06:22
And that gets me to one of the biggest deals about 3D printing.
127
382278
3145
06:25
With 3D printing, complexity is free.
128
385423
2861
06:28
The printer doesn't care
129
388284
2862
06:31
if it makes the most rudimentary shape
130
391146
2644
06:33
or the most complex shape,
131
393790
2200
06:35
and that is completely turning design
132
395990
3158
06:39
and manufacturing on its head as we know it.
133
399148
3546
06:42
Many people think that 3D printing will be
134
402694
2327
06:45
the end of manufacturing as we know it.
135
405021
3738
06:48
I think that it's the opportunity to put
136
408759
2513
06:51
tomorrow's technology in the hands of youngsters
137
411272
3661
06:54
that will create endless abundance
138
414933
2603
06:57
of job opportunities,
139
417536
1920
06:59
and with that,
140
419456
1964
07:01
everybody can become an expert maker
141
421420
2894
07:04
and an expert manufacturer.
142
424314
2104
07:06
That will take new tools.
143
426418
1886
07:08
Not everybody knows how to use CAD,
144
428304
2733
07:11
so we're developing haptics,
145
431037
2043
07:13
perceptual devices
146
433080
1939
07:15
that will allow you to touch
147
435019
1901
07:16
and feel your designs
148
436920
1765
07:18
as if you play with digital clay.
149
438685
2878
07:21
When you do things like that,
150
441563
1697
07:23
and we also developed things that take
151
443260
2003
07:25
physical photographs that are instantly printable,
152
445263
2554
07:27
it will make it easier to create content,
153
447817
2650
07:30
but with all of the unimagined,
154
450467
3031
07:33
we will also have the unintended,
155
453498
2392
07:35
like democratized counterfeiting
156
455890
5276
07:41
and ubiquitous illegal possession.
157
461166
2984
07:44
So many people ask me,
158
464150
1483
07:45
will we have a 3D printer in every home?
159
465633
2508
07:48
I think it's the wrong question to ask.
160
468141
2253
07:50
The right question to ask is,
161
470394
1381
07:51
how will 3D printing change my life?
162
471775
3765
07:55
Or, in other words, what room in my house
163
475540
2190
07:57
will 3D printing fit in?
164
477730
2164
07:59
So everything that you see here
165
479894
1996
08:01
has been 3D printed,
166
481890
2111
08:04
including these shoes
167
484001
3079
08:07
at the Amsterdam fashion show.
168
487080
2242
08:09
Now, these are not my grandfather's shoes.
169
489322
3696
08:13
These are shoes that represent
170
493018
1692
08:14
the continuation of his passion
171
494710
2198
08:16
for hyper-local manufacturing.
172
496908
2380
08:19
My grandfather didn't get to see Nike
173
499288
5243
08:24
printing cleats for the recent Super Bowl,
174
504531
4549
08:29
and my father didn't get to see me standing
175
509080
3407
08:32
in my hybridized 3D printed shoes.
176
512487
3110
08:35
He passed away three years ago.
177
515597
2751
08:38
But Chuck Hull, the man that invented it all,
178
518348
3243
08:41
is right here in the house today,
179
521591
2369
08:43
and thanks to him,
180
523960
1782
08:45
I can say, thanks to his invention, I can say
181
525742
2718
08:48
that I am a cobbler too,
182
528460
1977
08:50
and by standing in these shoes
183
530437
2454
08:52
I am honoring my past
184
532891
2334
08:55
while manufacturing the future.
185
535225
2152
08:57
Thank you.
186
537377
