Kyle von Hasseln: This is a 3D printed dress.

The designer uses wearable, flexible plastic

設計師用耐穿、具延展性的塑膠

to create incredible detail  and volume in her clothes.

在這服裝創造出極佳的細部表現和質感。

Doctors from the University of Michigan created custom support

密西根大學的醫生客製化這氣管支架

for the airway of a baby who was born  unable to breathe on his own,

給出生後無法自行呼吸的寶寶，

so it will disolve over time  as his airway reforms around it.

當寶寶的呼吸道有所改善，支架會逐漸分解。

The designer, Scott Summit  uses resin and plastic and metal,

設計師Scott Summit  用樹脂、塑膠和金屬

They go way past the idea of just replacing a limb,

他們做的遠勝於取代失去的肢體，

and become an expression of individuality.

These 3 projects are examples of the best thing about a 3D printer,

以上三個企劃示範了3D列印的優點

because there are a lot of  amazing things about a 3D printer.

A 3D printer can make  something very accurately.

it can make it with very little material and very little energy,

使用很少的素材，消耗非常少能源，

and it can make it exactly  when and where you need it.

還可以隨時隨地配合你的需求。

A 3D printer is more than a 3D photocopier,

it makes something  that has never existed before.

So the dress, the airway brace,  and the prosthetic leg,

the key to those innovations is that their authors saw the 3D printer

不是把3D列印機視為生產設備，

"What can I do with this tool, that has never been possible before?"

"用這樣的工具我能做 哪些以前不可能辦到的事?"

We asked ourselves a similar question a couple of years ago,

幾年前我們曾問過類似的問題。

we had promised to make our friend Chelsea a cake for her birthday.

當時我們答應為朋友雀喜烤一個生日蛋糕，

And as the day approached,  we went shopping

當她生日快到時，我們買了所有食材

to get all the ingredients  to bake it from scratch,

and we brought them home and unpacked all the groceries

我們把東西扛回住所，打開包裝，

in our tiny graduate studio apartment that we had just moved into.

在一間剛搬進去的狹小研究生公寓。

And as we were standing there  in the kitchen,

we suddenly realized,  that we actually didn't own an oven.

We didn't own an oven  but we did own a 3D printer.

我們沒有烤箱，但是有3D列印機。

所以，很自然地，我們開始猜想

"Would it be possible to just  3D print her a cake instead?"

"有可能為她3D列印一個蛋糕嗎?"

And we tried, and we tried  recipe after recipe,

and using every kind of sugar  that we could find

mixed together in every ratio  that we could think of,

that actually lasted  well past her actual birthday,

we finally managed to 3D print Chelsea a tiny cupcake topper

我們終於成功為雀喜列印了 一個小小的杯子蛋糕裝飾，

她很喜歡這裝飾，而我們也意識到

other people would  probably love this too.

So when we graduated about a year ago, we founded the sugar lab,

所以大約一年前畢業後，我們成立了一間糖研究室，

a custom design firm  for 3D printed sugar.

一間3D列印客製化糖品的設計公司。

Using the same process that we had developed

and that process is actually really simple at its core.

Its essentially just adding water to sugar.

So if you've ever made frosting,  and left the bowl in the sink overnight,

如果把製做糖霜的碗丟在水槽一整晚，

the bowl is gonna be impossible to scrape out.

是不可能把碗裡的糖霜刮乾淨的。

And thats because when you add  water to sugar it solidifies,

we just add the water  in a very precise way.

而我們只是用非常精準的方式加水。

3 dimensional model of the object  we'd like to 3d print in sugar.

想用糖3D列印的立體數位模型，

We run that model through software that slices it into layers.

之後，用軟體將模型分成不同的圖層，

These layers will be fed  to the 3d printer one at a time,

When that happens the printer  spreads out a very fine layer of sugar,

列印時，機器先撒上一層非常細的糖。

and it uses an inkjet printhead  just like the one you would find

to paint that bottom  most crosssection of the object,

onto the layer of sugar, only using water instead of ink.

再用水，而不是墨水，覆蓋在糖上面

Then the printer spreads another  very fine layer of sugar

然後機器會在第一層上面再撒上

and it paints the next cross  section with water.

And it repeats this often  many thousands of times,

until every layer of the object  has been printed,

from the very bottom layer, up to the very top layer.

At that point the digital model that a few hours earlier

we could only look at on our computer screen

還只能在電腦螢幕上看的數位模型，

變成一個摸得到、有形的成品，

This particular sugar object  we designed as a cake topper,

這個我們設計成為蛋糕裝飾的獨特成品，

which makes this essentially 3d printed frosting.

But you can tell right away that this frosting

it can be geometric and mathematically precise.

可以是幾何圖形，而且數目精確，

This frosting can basically look like  almost anything you can think of

基本上，糖霜可以看起來像任何你能想到的東西，

So you can 3D print custom  sugar party favors,

所以你可以客製列印喜愛的派對糖品，

or crazy little curly sugar cubes for your coffee.

或是加咖啡的古怪捲曲小糖球，

Or later in the day, you can print a sugar lattice

或是在傍晚時分，你可以列印個糖格子
