    THE PRESENT AND FUTURE OF 3D PRINTING
  • 00:00:27
    THE SECRET OF 3D PRINTER
  • 00:00:30
    Living in a modern world
  • 00:00:31
    you should know very well about digital printer
  • 00:00:33
    CHEN GUANHAO, HOST
  • 00:00:34
    We're even able to list them
  • 00:00:35
    inkjet printer, laser printer and so on
  • 00:00:39
    But do you know how a 3D printer works?
  • 00:00:42
    And what are the varieties of 3D printers?
  • 00:00:45
    Have you ever thought about how 3D printers print foods
  • 00:00:48
    hearts, cars, and even airplanes?
  • 00:00:52
    Today, let's follow me and reveal the mysteries of 3D printing
  • 00:00:54
    and reveal the mysteries of 3D printing
  • 00:00:57
    Let's go
  • 00:00:59
    Conventional manufacturing method, such as CNC
  • 00:01:02
    is subtractive manufacturing
  • 00:01:03
    It is like wood carving
  • 00:01:05
    getting rid of the unwanted parts
  • 00:01:07
    and keeping what is needed
  • 00:01:12
    As opposed to CNC being subtractive manufacturing
  • 00:01:14
    3D printing is additive manufacturing
  • 00:01:16
    It's a process of stacking layers of material together
  • 00:01:18
    to shape the products that we want
  • 00:01:20
    Professor Zheng, am I correct?
  • 00:01:22
    Yes, that's correct
  • 00:01:24
    ZHENG ZHENGYUAN, PROFESSOR OF MECHANICAL ENGINEERING, NTUST
  • 00:01:28
    3D printing is achieved by stacking material together layer by layer
  • 00:01:29
    As the name suggests
  • 00:01:34
    it's a type of printing method
  • 00:01:38
    How many types of printers do you know?
  • 00:01:41
    Printers
  • 00:01:42
    I can think of laser printer and inkjet printer
  • 00:01:45
    That's right
  • 00:01:46
    The concept of 3D printing
  • 00:01:49
    is the same as regular printing
  • 00:01:51
    It involves laser fusing material
  • 00:01:53
    or inkjet shaping a product
  • 00:01:57
    It's just that regular printers print on paper
  • 00:01:59
    And now, 3D printers print on plastic
  • 00:02:03
    metal, ceramic or other materials
  • 00:02:06
    to build a product layer by layer
  • 00:02:09
    Professor Zheng, you've just mentioned
  • 00:02:11
    that there are different types of 3D printers
  • 00:02:13
    If I have different needs
  • 00:02:14
    let's say I want to print a fish like this
  • 00:02:16
    and an automotive engine
  • 00:02:20
    can I use the same 3D printer?
  • 00:02:22
    Of course not
  • 00:02:23
    Something like this is relatively cheap
  • 00:02:26
    It has a rough surface finish as well
  • 00:02:28
    It doesn't has important functionality
  • 00:02:31
    Functionality is a key element, closely related to cost
  • 00:02:35
    To make things like this
  • 00:02:36
    we can use cheaper equipment
  • 00:02:38
    with a lower level of resolution
  • 00:02:40
    And you know, aircraft engine is very valuable
  • 00:02:43
    It used to take over 800 parts to make one
  • 00:02:45
    now we only need to print 12 parts
  • 00:02:47
    to assemble an engine
  • 00:02:48
    Materials are fused together with laser
  • 00:02:50
    3D laser printers used for printing aircraft engine
  • 00:02:52
    cost tens of millions of dollars
  • 00:02:55
    That's very expensive.Yes
  • 00:02:57
    By choosing materials and shaping methods
  • 00:03:00
    required for your product
  • 00:03:01
    you can print anything you want
  • 00:03:04
    That's what makes 3D printing so magical
  • 00:03:08
    I don't think I can afford printing an aircraft engine
  • 00:03:10
    Let's just print this cute little fish
  • 00:03:16
    I think my fish is ready
  • 00:03:18
    I'm going to dish it up
  • 00:03:20
    Usually there should be steam
  • 00:03:21
    coming from the machine
  • 00:03:23
    Let's lift it up
  • 00:03:25
    Professor, you see, my fish is ready
  • 00:03:27
    But why isn't there any meat?
  • 00:03:29
    Didn't you just secretly eat it?
  • 00:03:32
    No, I didn't
  • 00:03:33
    If the meat was included in your design
  • 00:03:35
    it'd be in the end product
  • 00:03:36
    Whatever you've designed
  • 00:03:37
    is exactly what you've got via 3D printing
  • 00:03:40
    Professor, I've been thinking
  • 00:03:42
    It took us less than an hour
  • 00:03:45
    to make this
  • 00:03:47
    Without 3D printing
  • 00:03:49
    how long will it take to make something like this?
  • 00:03:52
    You see, the fish is composed of nine parts
  • 00:03:55
    So nine molds will be required
  • 00:03:57
    Nine molds will take three months
  • 00:04:00
    and 300,000 dollars to make
  • 00:04:02
    My gosh
  • 00:04:03
    Do you mean 300,000 dollars for one mold?
  • 00:04:05
    Yes. So nine molds will take
  • 00:04:06
    Nearly three million dollars
  • 00:04:09
    Are you telling me it would take three months
  • 00:04:12
    and three million dollars?Yes
  • 00:04:13
    This keyring is very expensive
  • 00:04:15
    Yes
  • 00:04:16
    So with conventional manufacturing
  • 00:04:18
    it takes a long time to produce
  • 00:04:20
    such a complicatedly structured product
  • 00:04:23
    You can imagine the number of fish
  • 00:04:26
    we need to sell to cover the cost
  • 00:04:29
    Therefore
  • 00:04:30
    when it comes to small-volume,and large-variety production
  • 00:04:34
    3D printing has great advantage
  • 00:04:37
    It's this huge advantage
  • 00:04:40
    that attracts the academics and the commerce sectors
  • 00:04:42
    in the whole world
  • 00:04:43
    to jump on this technology bandwagon
  • 00:04:47
    Now let's fly with me out of Taiwan
  • 00:04:48
    and explore the multifaceted 3D printing technology
  • 00:04:54
    KUNSHAN, SUZHOU
  • 00:04:58
    My first stop is Kunshan, Suzhou
  • 00:05:01
    We can definitely find some amazing 3D printers
  • 00:05:03
    in this industrial town
  • 00:05:05
    However, these products
  • 00:05:07
    are not quite what I've expected
  • 00:05:09
    Am I here to buy models
  • 00:05:11
    or musical instruments?
  • 00:05:13
    No, I'm here to look for 3D printers
  • 00:05:15
    This is just the showcase floor
  • 00:05:17
    Here in this technology company
  • 00:05:19
    they have many self-developed 3D printers
  • 00:05:22
    Any 3D printers used in different industries
  • 00:05:24
    can be found here
  • 00:05:29
    What is it printing?
  • 00:05:30
    It's hard to tell
  • 00:05:31
    What is it?
  • 00:05:32
    It is what I've just printed
  • 00:05:34
    I've just printed a screw
  • 00:05:36
    A screw?A bolt
  • 00:05:38
    A bolt?
  • 00:05:39
    FUSED DEPOSITION MODELING (FDM) 3D PRINTER
  • 00:05:40
    But the texture doesn't look like metal
  • 00:05:43
    Could it be..
  • 00:05:45
    newly developed high-tech material?
  • 00:05:47
    This is a bolt that I've just printed
  • 00:05:49
    A bolt
  • 00:05:50
    Normally we'd expect a bolt
  • 00:05:52
    to be made of metal
  • 00:05:53
    Right? No, this is made of
  • 00:05:54
    a high-performance plastic, known as PC ZHAO YULIN, ASSISTANT GM, 3D PRINTING TECH COMPAN
  • 00:05:57
    At the back, you can see there is a coil
  • 00:05:59
    of very thin wire rod with a radius of 1.75 cm
  • 00:06:03
    It's heated and melted and then extruded layer by layer
  • 00:06:07
    Guess what these bolts are for?
  • 00:06:09
    I'm not sure, furniture?
  • 00:06:11
    Furniture? Yes
  • 00:06:11
    They will be used to make a car jack
  • 00:06:14
    It's what we use to lift a vehicle
  • 00:06:15
    To jack up a vehicle?
  • 00:06:17
    Yes, because they have a high shear strength
  • 00:06:18
    Really?
  • 00:06:20
    But...
  • 00:06:21
    normally we'd expect it to be made of metal
  • 00:06:23
    So does this have enough shear strength?
  • 00:06:25
    There has been a rapid development in materials
  • 00:06:27
    Nowadays,high-performance plastics
  • 00:06:29
    are in the same performance realm as metals
  • 00:06:31
    Their strength is comparable to stainless steel
  • 00:06:33
    How much weight can this bolt withstand?
  • 00:06:36
    This bolt can withstand about one-ton load
  • 00:06:39
    One ton?Yes
  • 00:06:41
    So it can be used to make a car jack
  • 00:06:43
    Definitely, let me show you a car jack that we've printed
  • 00:06:46
    The bolts are in there
  • 00:06:47
    So not just the bolts
  • 00:06:48
    the whole thing is printed with 3D printing, isn't it?
  • 00:06:50
    The entire jack is printed
  • 00:06:52
    with this 3D printer
  • 00:06:54
    That's impressive.Yes
  • 00:06:57
    Let's test its strength to see if it's really that impressive
  • 00:06:59
    Can this 3D-printed plastic car jack
  • 00:07:02
    bear the weight of a car?
  • 00:07:05
    It's really able to lift a car
  • 00:07:08
    Let's try it out
  • 00:07:09
    That's astounding
  • 00:07:12
    I can feel that the car is being lift up
  • 00:07:18
    That's amazing
  • 00:07:19
    The wheel can spin
  • 00:07:21
    Yes
  • 00:07:23
    It's incredible
  • 00:07:25
    The entire car jack is printed with 3D printing
  • 00:07:28
    Yes
  • 00:07:28
    Every part of it is printed with 3D printing
  • 00:07:30
    And it's made of plastic
  • 00:07:32
    Yes.That's impressive
  • 00:07:33
    Right
  • 00:07:34
    Mr. Zhao, have you put this product on the market?
  • 00:07:36
    No, we don't sell this
  • 00:07:37
    We only provide printing services on request
  • 00:07:40
    We only provide printing services on request
  • 00:07:42
    we'll help them print it
  • 00:07:43
    So the reason why you've made this jack
  • 00:07:44
    is that you want to prove
  • 00:07:45
    that your products are very durable
  • 00:07:47
    And sturdy.That's right
  • 00:07:49
    All printed creations are functional components
  • 00:07:50
    That's amazing
  • 00:07:51
    Plastic products produced with 3D printing technology
  • 00:07:54
    are as strong as their metal counterparts
  • 00:07:57
    This equipment has absolutely amazed me
  • 00:08:00
    Next, we're going to
  • 00:08:01
    check out a commonly talked about
  • 00:08:04
    but almost unimaginable 3D printing technology
  • 00:08:07
    Take a guess
  • 00:08:08
    What does this machine do?
  • 00:08:10
    Well...
  • 00:08:12
    It looks mysterious
  • 00:08:13
    I wonder what it print
  • 00:08:14
    Glass?Right
  • 00:08:15
    It probably prints some sort of fragile item, like glass
  • 00:08:18
    This is actually a 3D bio-printer
  • 00:08:21
    LIU FUTAN, DEVELOPMENT ENGINEER, 3D PRINTING TECH COMPANY
  • 00:08:22
    You mean it prints cells.Yes
  • 00:08:25
    How does that work?
  • 00:08:29
    Well, this is a print bed
  • 00:08:32
    Next
  • 00:08:34
    The extruder is controlled by the electrical machine
  • 00:08:37
    to move along the X, Y, Z axes
  • 00:08:40
    And this is...
  • 00:08:42
    So what would be the infill then?
  • 00:08:44
    It's like this
  • 00:08:45
    This is an infill cartridge
  • 00:08:48
    Before printing
  • 00:08:50
    we'll put the infill material into this cartridge
  • 00:08:54
    It's a type of bio-inspired hydrogel
  • 00:08:56
    And then
  • 00:08:58
    The bio-inspired hydrogel will be fused into the cells
  • 00:09:01
    That's the concept of this 3D bio-printer
  • 00:09:04
    So this is the legendary 3D bio-printer
  • 00:09:08
    Would I get to witness
  • 00:09:09
    the process of printing a human organ?
  • 00:09:12
    So what would the printed products look like?
  • 00:09:15
    There are two main types of products
  • 00:09:18
    One is in a grid shape like this
  • 00:09:22
    We call it cytoskeletal
  • 00:09:24
    It's a common component in tissue engineering
  • 00:09:28
    This is printed with hydrogel
  • 00:09:30
    Its function is
  • 00:09:32
    like building a house for the cells to grow
  • 00:09:37
    So this hyped bioprinting technology
  • 00:09:40
    does not actually print a human organ
  • 00:09:42
    but build a house for the cells
  • 00:09:45
    For instance, an ear-shaped bio-container is printed
  • 00:09:47
    as a house for the cells
  • 00:09:49
    to grow into what we want
  • 00:09:51
    to be transplanted into humans
  • 00:09:54
    Although it doesn't directly print a human organ
  • 00:09:55
    this technology is still an epoch-making invention
  • 00:10:03
    What is this?
  • 00:10:04
    This is a 3D ceramic printer
  • 00:10:06
    It's now printing something
  • 00:10:07
    It takes a laser operated at a power of only 0.6 watt
  • 00:10:11
    It's enough to solidify the product
  • 00:10:13
    XU TAN, R&D SUPERVISOR 3D PRINTING TECH COMPANY
  • 00:10:14
    So is 0.6 watt a high power?
  • 00:10:17
    No
  • 00:10:18
    If you are to print metal
  • 00:10:20
    it'd require a higher wattage
  • 00:10:22
    like hundreds and thousands of watts
  • 00:10:24
    That's a big difference.Yes
  • 00:10:26
    If you stick your hand in this, I think you'd be fine
  • 00:10:29
    I'd rather not
  • 00:10:31
    You'd rather not
  • 00:10:32
    You can see it's smoking
  • 00:10:34
    In comparison
  • 00:10:35
    as it's still smoking
  • 00:10:36
    the wattage of its laser
  • 00:10:37
    is probably higher
  • 00:10:40
    Mr. Xu, stop joking around
  • 00:10:41
    LASER SLA 3D Printer
  • 00:10:42
    Although the UV laser operates at a low wattage
  • 00:10:45
    during operation
  • 00:10:46
    you can see white smoke
  • 00:10:48
    coming out of the photosensitive resin
  • 00:10:50
    I think I'll just keep listening to the introduction
  • 00:10:53
    What kind of products involve
  • 00:10:56
    ceramic 3D printing?
  • 00:10:59
    In general, ceramic 3D printing
  • 00:10:59
    is used to print products
  • 00:11:02
    that are customized...and complexly structured
  • 00:11:05
    For those products
  • 00:11:07
    that are difficult to made
  • 00:11:10
    by conventional manufacturing
  • 00:11:11
    we can use this technology instead
  • 00:11:12
    It's particularly suitable for customized products
  • 00:11:15
    like prosthetic teeth
  • 00:11:16
    Everyone's prosthetic teeth are different
  • 00:11:17
    Prosthetic teeth?Yes
  • 00:11:19
    Everyone's teeth align differently
  • 00:11:21
    So it's impossible to use batch production
  • 00:11:23
    for prosthetic teeth
  • 00:11:24
    But if we use this,all you need is the design
  • 00:11:27
    Then you can just print it directly
  • 00:11:32
    In my trip to Kunshan, Suzhou, I've found out
  • 00:11:35
    laser sintering
  • 00:11:36
    stereolithography
  • 00:11:37
    fused deposition modeling, and so on
  • 00:11:38
    are all different types of 3D printers
  • 00:11:40
    What about printing materials?
  • 00:11:42
    Materials are also a key element in 3D printing
  • 00:11:45
    This material developing factory in Shanghai
  • 00:11:48
    has done intensive research
  • 00:11:50
    on 3D printing materials
  • 00:11:53
    Mr. Qu, I'm very curious
  • 00:11:55
    Among these materials
  • 00:11:57
    how do you choose
  • 00:11:58
    for a particular application?
  • 00:12:00
    Yes, that is a common question raised by the clients
  • 00:12:04
    Let's start with a simple example
  • 00:12:06
    QU HANG, VP OF MARKETING SHANGHAI 3D MATERIAL TECH COMPANY
  • 00:12:07
    A designer has designed a cell phone, a toy
  • 00:12:10
    or an automotive part for the vehicles
  • 00:12:14
    In this case
  • 00:12:16
    if the designer wants to know how the end product looks like
  • 00:12:19
    the simplest and the best option is PLA
  • 00:12:22
    It's because it shapes faster,and doesn't bend easily
  • 00:12:26
    In that case
  • 00:12:28
    you aim to achieve the highest level of precisio
  • 00:12:30
    in terms of size
  • 00:12:31
    FDM 3D PRINTER WITH PLA MATERIAL
  • 00:12:33
    Let's say I've designed an auto part
  • 00:12:35
    which requires a length of 3 millimeters
  • 00:12:37
    It has to be precise
  • 00:12:38
    Using PLA will be able to achieve the highest level of precision
  • 00:12:43
    in an expeditious way
  • 00:12:44
    But the problem with PLA is it can't bear too much weigh
  • 00:12:47
    So PLA products
  • 00:12:48
    It's only about the look. That's right
  • 00:12:50
    It's only about the appearance
  • 00:12:51
    As long as you can see the design
  • 00:12:52
    then its job is done
  • 00:12:55
    So if you're on a tight schedule
  • 00:12:57
    and the product is only for visual purpose
  • 00:12:59
    rather than loadbearing function
  • 00:13:02
    PLA is a good option
  • 00:13:04
    Yes, it is indeed
  • 00:13:06
    To put it simply
  • 00:13:07
    the purpose of a product
  • 00:13:10
    dictates the choice of materials
  • 00:13:12
    Not only can this factory provide a selection of plastics
  • 00:13:16
    but more impressively
  • 00:13:17
    they can customize the materials
  • 00:13:19
    according to the client's needs
  • 00:13:21
    Every industry has different demands for materials
  • 00:13:24
    Aircraft parts need to be made of fire-retardant materials
  • 00:13:25
    In case of a fire
  • 00:13:27
    you've got to make sure the parts don't burn
  • 00:13:29
    and are able to stop the spread of fire quickly
  • 00:13:31
    All materials used to make aircraft parts
  • 00:13:33
    basically must meet the flammability standard of V0
  • 00:13:37
    V0 is a rating in UL's plastics flammability standard
  • 00:13:40
    We have specifically developed for the aircrafts
  • 00:13:43
    a type of polycarbonate that is fire-retardant
  • 00:13:46
    This type of PC meets the standards for aircraft use
  • 00:13:50
    It's currently used on the aircrafts of an airliner
  • 00:13:54
    3D printing has been designed to achieve customization
  • 00:13:58
    so materials can also be modified and developed
  • 00:14:01
    to satisfy the client's needs
  • 00:14:03
    From front-end manufacturing
  • 00:14:05
    to back-end manufacturing
  • 00:14:06
    3D printing is a fully customizable technology
  • 00:14:11
    TAIPEI
  • 00:14:14
    I've traveled to a few places and seen various 3D printers
  • 00:14:17
    But what about the development of 3D printers in Taiwan?
  • 00:14:20
    The company right behind me
  • 00:14:22
    has the answer I'm looking for
  • 00:14:23
    Let's go
  • 00:14:34
    Character figurines
  • 00:14:36
    And this delicious-looking gaifan model
  • 00:14:40
    I suppose these are all printed with 3D printing technology
  • 00:14:45
    But what about this
  • 00:14:47
    Hey, Gary
  • 00:14:49
    I suppose this is not a 3D printed product, is it?
  • 00:14:51
    All of them are.Really?
  • 00:14:52
    SENIOR MANAGER, SHU JIA
  • 00:14:53
    MARKET DEVELOPMENT
  • 00:14:54
    Everything you see on the table is printed in one piece
  • 00:14:55
    with 3D printing technology
  • 00:14:56
    Really? Even this one?
  • 00:14:57
    Yes
  • 00:14:58
    But it's a vase
  • 00:15:01
    With today's 3D printing technology
  • 00:15:03
    you can make a vase as beautiful as this
  • 00:15:05
    Are all these machines designed in-house?
  • 00:15:08
    Yes, they are all developed,designed and produced in-house
  • 00:15:12
    They are all in-house products
  • 00:15:14
    Can you please show me around?
  • 00:15:15
    Sure, let's check them out
  • 00:15:17
    In this global trend of 3D printing technology
  • 00:15:19
    Taiwan has been a competitor
  • 00:15:21
    From printers for general use
  • 00:15:23
    printers for delicate crafting
  • 00:15:25
    to large industrial-strength printers
  • 00:15:27
    you can find all kinds of 3D printers here
  • 00:15:29
    Moreover, Gary has said
  • 00:15:31
    they have this one and only 3D printer in the world
  • 00:15:34
    And I get to try it out myself
  • 00:15:38
    I think Gary has noticed. I'm a glutton
  • 00:15:40
    That's why he has given me a hamburger
  • 00:15:42
    It looks very delicious
  • 00:15:43
    Let's have a try
  • 00:15:49
    Gary, why don't you stop me?
  • 00:15:51
    No, because I want to see
  • 00:15:52
    what would happen if someone actually bites it
  • 00:15:53
    I'm eating it for real
  • 00:15:55
    Please do
  • 00:15:57
    We've used our latest full-color 3D printing technology
  • 00:16:00
    to print this hamburger model
  • 00:16:02
    You can have a try
  • 00:16:03
    Gary, you've said this is
  • 00:16:05
    full color
  • 00:16:06
    Do you mean every layer of it
  • 00:16:07
    including the meat and vegetables
  • 00:16:09
    is not individually printed
  • 00:16:10
    and held together with glue?
  • 00:16:12
    Actually, the process begins with 3D scanning software
  • 00:16:15
    Whether it be scanning a hamburger
  • 00:16:17
    or drawing a hamburger on the computer
  • 00:16:20
    we then use this latest full-color 3D printer
  • 00:16:23
    to print the product in one piece
  • 00:16:28
    Gary, are you saying this is the one and only 3D printer
  • 00:16:31
    in the whole world?Yes
  • 00:16:33
    What's so unique about it?
  • 00:16:35
    I'm not saying
  • 00:16:36
    this is the only full-color 3D printer in the world
  • 00:16:38
    But most 3D printers at consumer level
  • 00:16:41
    can only print in one color
  • 00:16:44
    One ink, one color
  • 00:16:46
    Products like this
  • 00:16:47
    However, we've also adopted
  • 00:16:49
    a familiar inkjet printing technology
  • 00:16:52
    that allows materials to be added layer by layer
  • 00:16:54
    to achieve full color effects
  • 00:16:55
    So far, this technology can't be found elsewhere
  • 00:17:00
    Taiwan's self-developed full-color 3D printer
  • 00:17:03
    sounds really impressive
  • 00:17:05
    More importantly
  • 00:17:06
    it's been described as the most friendly printer
  • 00:17:09
    because of its surprising price
  • 00:17:13
    Back then
  • 00:17:14
    it cost an arm and a leg
  • 00:17:16
    to achieve full-color 3D printing
  • 00:17:17
    A printer would cost at least millions of Taiwan dollars
  • 00:17:20
    But...Millions
  • 00:17:21
    We hope to provide
  • 00:17:22
    an equipment with this new technology
  • 00:17:25
    at an affordable price
  • 00:17:27
    for the general consumers
  • 00:17:29
    and individual entrepreneurs
  • 00:17:33
    This is not just a price war
  • 00:17:35
    Despite its modest price tag
  • 00:17:37
    it can produce amazingly colorful creations
  • 00:17:40
    with incredible quality
  • 00:17:43
    Gary, you know what
  • 00:17:44
    I like things that are flexible like this
  • 00:17:46
    Can I print a Mona Lisa?
  • 00:17:49
    Not only can you print a Mona Lisa
  • 00:17:51
    but also a "Mona Guan Hao" if you want
  • 00:17:54
    All you need is your photo
  • 00:17:55
    I just need my photo to print this
  • 00:17:57
    Yes
  • 00:17:58
    But this is 3D.Yes
  • 00:18:00
    All we need to do is using our special technique
  • 00:18:03
    to attach your photo on it
  • 00:18:05
    So is this also a kind of customization?
  • 00:18:07
    Yes, one characteristic of 3D printing
  • 00:18:08
    is high level of customization
  • 00:18:11
    I didn't expect that I got to use
  • 00:18:12
    the world's one and only full-color 3D printer
  • 00:18:15
    to print a personalized mouse pad with my face on it
  • 00:18:18
    What will it look like?
  • 00:18:20
    No hurry
  • 00:18:22
    While it's printing
  • 00:18:24
    let's see what other 3D printers
  • 00:18:25
    have been developed in Taiwan
  • 00:18:28
    I'm not robbing a bank
  • 00:18:30
    Look at these rings
  • 00:18:32
    Have you noticed something?
  • 00:18:33
    There is no diamond on them
  • 00:18:36
    Gary, why isn't there diamond on these rings?
  • 00:18:38
    These are some products using 3D printing technology
  • 00:18:43
    Are all these printed with 3D printing technology?
  • 00:18:45
    Are all these printed with 3D printing technology?
  • 00:18:47
    according to these 3D-printed models
  • 00:18:49
    When the designers have approved the design
  • 00:18:51
    they will proceed to rollover and make the real ones
  • 00:18:54
    Why don't they just
  • 00:18:55
    skip to print the real ones?
  • 00:18:58
    Although metal 3D printing can achieve that
  • 00:19:00
    yet it costs dearly
  • 00:19:02
    And the precision is not as good as the photosensitive resin
  • 00:19:07
    The jewelry industry has a very high standard
  • 00:19:11
    requiring a precision of 50 micrometers
  • 00:19:13
    This degree of precision
  • 00:19:14
    can only be achieved with this technology
  • 00:19:16
    So does that mean this equipment
  • 00:19:19
    is specifically used for jewelry design?
  • 00:19:20
    Apart from jewelry design
  • 00:19:22
    another application
  • 00:19:22
    also requires high level of precision
  • 00:19:24
    and customization
  • 00:19:25
    It's for dental or medical application
  • 00:19:29
    Dental application?
  • 00:19:30
    Really?
  • 00:19:31
    For instance,what you're holding
  • 00:19:34
    is a surgical guide template
  • 00:19:35
    It's designed for dentists or any other physicians
  • 00:19:40
    Before the operation
  • 00:19:41
    they need to locate the areas
  • 00:19:43
    for hole-drilling
  • 00:19:45
    and other surgical procedures on the patient
  • 00:19:48
    With 3D printing technology
  • 00:19:50
    a guide template like this can be printed
  • 00:19:52
    to allow the surgery to be performed
  • 00:19:55
    more precisely and efficiently
  • 00:19:57
    For high stand of precision as required by jewelry design
  • 00:20:00
    and medical application
  • 00:20:01
    they can come here
  • 00:20:02
    for the 3D printers that meet their needs
  • 00:20:05
    But don't think that
  • 00:20:06
    Taiwan's development of 3D printers
  • 00:20:08
    is limited to small to medium-sized equipment
  • 00:20:11
    In fact, the development of large-scale 3D printers
  • 00:20:13
    like laser sintering
  • 00:20:15
    used for printing industrial samples
  • 00:20:19
    is actually in full swing in Taiwan
  • 00:20:21
    To gain a deep understanding
  • 00:20:22
    of the weal and woe in the development process
  • 00:20:25
    I'm going to be a one-day engineer again
  • 00:20:27
    and see what I can find
  • 00:20:29
    Mr. Lu,
  • 00:20:30
    if I want to print a model figure
  • 00:20:31
    how long does it take to do so?
  • 00:20:34
    In terms of the equipment of other brands
  • 00:20:35
    LU SHINAN, ENGINEERING SUPERVISOR
  • 00:20:36
    that are equivalent to this one right here
  • 00:20:38
    it takes over 10 hours
  • 00:20:40
    to print a 10 cm model figure
  • 00:20:42
    But with this one
  • 00:20:43
    it takes around five hours to finish printing
  • 00:20:45
    Five hours?Yes
  • 00:20:46
    It's so much faster, isn't it?
  • 00:20:48
    That's right
  • 00:20:49
    What changes have you make
  • 00:20:51
    to speed up the process?
  • 00:20:54
    Let me explain to you
  • 00:20:56
    the concept of a 3D printer
  • 00:20:57
    3D means the X, Y, and Z axes. Right
  • 00:21:00
    The extruder has to move in all three dimensions
  • 00:21:02
    to build the product in layers
  • 00:21:05
    When we were designing this equipment
  • 00:21:07
    we thought
  • 00:21:08
    maybe we could speed up the printing process
  • 00:21:10
    So we came up with a new extruder
  • 00:21:13
    What is this?
  • 00:21:14
    Its width is the same as that of a print
  • 00:21:18
    During the printing process
  • 00:21:20
    it simply takes one travel move
  • 00:21:24
    to finish one print
  • 00:21:25
    Unlike regular printers
  • 00:21:26
    it doesn't have to travel
  • 00:21:28
    along the Y axis
  • 00:21:30
    It doesn't need to travel back and forth
  • 00:21:31
    Exactly. It doesn't need to travel back and forth
  • 00:21:33
    It simply needs to travel along the X axis
  • 00:21:35
    to finish one print
  • 00:21:37
    That's why it's quicker
  • 00:21:38
    We can dispense with
  • 00:21:40
    the movement along the Y axis
  • 00:21:42
    In fact, among other movements
  • 00:21:44
    the Y axis movement
  • 00:21:45
    is most time-consuming
  • 00:21:48
    Therefore
  • 00:21:49
    our printer here is much faster than the others
  • 00:21:53
    Mr. Lu has also said
  • 00:21:54
    while improving the print speed
  • 00:21:56
    the quality also needs to be taken into consideration
  • 00:21:58
    So basically, the ways to develop
  • 00:22:00
    a well-thought-out 3D printer
  • 00:22:03
    are what engineers need to work hard on
  • 00:22:06
    This is a model figure
  • 00:22:09
    we have just dug from the pot
  • 00:22:11
    A mummy.Yes
  • 00:22:12
    It looks exactly like
  • 00:22:14
    what's found in an archaeological dig
  • 00:22:17
    Yes.You have to wipe off
  • 00:22:19
    any remaining powder
  • 00:22:21
    Mr. Lu, as a professional engineer
  • 00:22:24
    are you optimistic about Taiwan's future
  • 00:22:28
    in 3D printing?
  • 00:22:29
    In my view
  • 00:22:31
    as long as people are willing to commit to this sector
  • 00:22:34
    Taiwan is suitable
  • 00:22:36
    for developing 3D printers
  • 00:22:39
    We already have talented people
  • 00:22:41
    Where there is demand
  • 00:22:43
    there will be supply
  • 00:22:45
    Over the past few years, people might think that
  • 00:22:48
    3D printing was beginning to wane
  • 00:22:50
    But they just didn't realize
  • 00:22:52
    how and where 3D printer could be applied
  • 00:22:54
    Demands will only rise
  • 00:22:56
    when people understand
  • 00:22:58
    the way this technology operates
  • 00:23:02
    People didn't realize before
  • 00:23:03
    Gradually
  • 00:23:05
    after we have done some promotional work
  • 00:23:07
    I guess a lot of students will be able to explain
  • 00:23:09
    what and how a 3D printer can do
  • 00:23:12
    In Taiwan, or the whole world
  • 00:23:14
    this technology
  • 00:23:16
    will gradually be popularized
  • 00:23:18
    and used in people's homes
  • 00:23:21
    Hopefully, in the not too distant future
  • 00:23:22
    more people will get to know
  • 00:23:24
    the advantages of 3D printing
  • 00:23:25
    and make use of them
  • 00:23:27
    to lead us to a newer and more convenient world
