00:00:00,080 --> 00:00:05,879
the printing press one of the greatest inventions of all time allowed for easy

2
00:00:04,200 --> 00:00:09,519
and Rapid printing of books and information which spread literacy and

3
00:00:07,600 --> 00:00:13,320
knowledge across the world the printing press revolutionized the spread of

4
00:00:11,200 --> 00:00:18,199
information but now a new method of printing called 3D printing is poised to

5
00:00:15,640 --> 00:00:23,160
revolutionize manufacturing the way it works is actually very simple using a 3D

6
00:00:20,560 --> 00:00:28,119
model as a guide a moving 3D printer head lays down a layer of material that

7
00:00:25,960 --> 00:00:32,239
has a certain amount of thickness to it then it does it again and again putting

8
00:00:30,240 --> 00:00:36,600
down one layer at a time until finally the completed model has been created

9
00:00:34,160 --> 00:00:41,320
literally from the ground up one slice at a time any complex object that cannot

10
00:00:39,440 --> 00:00:45,239
support its own weight during printing is printed along with some kind of

11
00:00:43,000 --> 00:00:49,440
scaffolding which can be easily removed or washed away once the object is

12
00:00:47,440 --> 00:00:53,239
completely printed 3D printing can be done with all sorts of materials

13
00:00:51,280 --> 00:00:59,280
different kinds of plastic metal Sandstone ceramic concrete wood and more

14
00:00:56,800 --> 00:01:04,720
and here is an example this is a Lego Technic comp ible 32 to gear you see I

15
00:01:02,719 --> 00:01:09,119
like to build robots in my spare time and while I have a lot of parts there

16
00:01:06,760 --> 00:01:13,799
are some very useful pieces that simply don't exist so 3D printing to the rescue

17
00:01:12,200 --> 00:01:18,119
once I knew what I wanted to make I needed to decide on some 3D modeling

18
00:01:15,960 --> 00:01:22,759
software to use there are a ton of options but I ended up using Google

19
00:01:19,960 --> 00:01:26,960
SketchUp which is easy to learn and use for a really powerful 3D program I would

20
00:01:25,040 --> 00:01:30,560
recommend blender but it does have a very steep learning curve once I

21
00:01:28,640 --> 00:01:34,920
finished making my 3D mod model I needed to figure out how I was going to print

22
00:01:32,439 --> 00:01:38,799
it you can buy or even build your own 3D printer but because the technology is

23
00:01:36,720 --> 00:01:43,280
still pretty new it's probably more worthwhile for most people to use a 3D

24
00:01:40,960 --> 00:01:47,600
printing service coincidentally as I was writing this episode a company called

25
00:01:45,159 --> 00:01:52,479
shapeways contacted us and offered to do some 3D printing for us I agreed and

26
00:01:49,920 --> 00:01:57,320
uploaded my exported STL files to their server I chose which pieces colors and

27
00:01:55,000 --> 00:02:01,680
what kind of material I wanted I went with strong and flexible plastic I was

28
00:02:00,119 --> 00:02:07,360
also pretty surprised to see that they can print in 14 karat gold that is one

29
00:02:04,719 --> 00:02:11,840
expensive gear a few weeks later I got a package in the mail containing all of my

30
00:02:09,280 --> 00:02:16,360
pieces as you can see the plastic is a lot different from real Lego it's rough

31
00:02:14,480 --> 00:02:20,360
and kind of chalky unless you get the polished stuff a lot of the pieces I

32
00:02:18,360 --> 00:02:24,319
designed are a bit too tight but they still fit with real Lego overall I'm

33
00:02:22,760 --> 00:02:27,840
very pleased with the results and I'll probably continue to design and print

34
00:02:25,959 --> 00:02:31,000
more pieces in the future if you'd like to print any of the pieces I've designed

35
00:02:29,480 --> 00:02:34,360
you can follow the link in the video description but being able to print

36
00:02:32,720 --> 00:02:38,959
little plastic gears is just the beginning for 3D printing imagine 3D

37
00:02:36,560 --> 00:02:42,640
printing an entire product from scratch does that remind you of anything you

38
00:02:40,560 --> 00:02:49,840
know like the replicators from Star Trek perhaps computer te Earl gry

39
00:02:46,599 --> 00:02:51,599
hot there you go okay so we probably

40
00:02:49,840 --> 00:02:56,040
won't be able to print out a new toaster or a cup of tea anytime soon but it's

41
00:02:53,879 --> 00:03:02,560
already possible to 3D print custom Prosthetics clothing food jewelry guns

42
00:02:59,879 --> 00:03:06,879
drugs even living skin cartilage and Bone scientists are currently working on

43
00:03:04,640 --> 00:03:11,840
ways to print entire organs like kidneys and livers and even with 3D printing in

44
00:03:09,159 --> 00:03:16,080
its infancy there are already many legal concerns about what people can do with

45
00:03:13,519 --> 00:03:20,400
3D printing technology easy homade weapon manufacturing and patent and

46
00:03:18,360 --> 00:03:24,159
copyright infringement among them keep an eye on this because it's going to be

47
00:03:22,239 --> 00:03:28,000
an interesting couple of decades something else to keep your eyes on

48
00:03:25,680 --> 00:03:32,760
shutterstock.com I actually made a special request to do this ad into ation

49
00:03:30,319 --> 00:03:36,439
because as a video editor I have a lot of very relevant things to say about

50
00:03:34,640 --> 00:03:40,840
them I've been using Shutterstock for the past 3 months and I love it we make

51
00:03:38,879 --> 00:03:45,159
a ton of videos at Lin's Media Group and before we got Shutterstock it was always

52
00:03:42,879 --> 00:03:49,120
such a pain to get usable images of things that I needed I can't use Google

53
00:03:47,400 --> 00:03:53,159
Images because most of those aren't licensed for reuse and they're usually

54
00:03:51,000 --> 00:03:57,480
too small anyway Shutterstock is great because they have more than 35 million

55
00:03:55,239 --> 00:04:01,040
images all of them carefully labeled and easily searchable and you don't even

56
00:03:59,280 --> 00:04:05,040
need an account to see what they have to offer also a lot of the images have

57
00:04:03,159 --> 00:04:09,200
their subjects isolated on a white background which is perfect for

58
00:04:07,000 --> 00:04:13,480
compositing in Photoshop or elsewhere and most images are available in

59
00:04:11,159 --> 00:04:17,280
enormous resolutions which is very useful for video and image creation

60
00:04:15,879 --> 00:04:21,479
whatever your project might be Shutterstock has lots of different plans
