Digital manufacturing is also allowing us to do this more effectively. In this case, it's actually creating the theoretical limit of strength for a material.
數(shù)字化制造也可以幫助我們進(jìn)行更有效的回收再利用。這個(gè)例子說(shuō)明了一種材料的理論極限強(qiáng)度。
you cannot get any stronger for the amount of material than this shape. So it's a basic simple block,
你不可能找到比這強(qiáng)度更強(qiáng)的模型。這是一個(gè)基本的、簡(jiǎn)單的方塊，
but the idea is, I can extrapolate this, I can make it into large formats, I can make it into buildings, bridges, but also airplane wings and shoes.
但我可以在此基礎(chǔ)上進(jìn)行延伸，并制作一些大型的東西，比如用來(lái)建樓、造橋，還可以用來(lái)制作飛機(jī)機(jī)翼和普通的鞋子。
The idea here is, I'm minimizing the amount of material. Here's a good example from architecture.
這背后的邏輯就是將使用的材料降到最少。這是一個(gè)來(lái)自建筑業(yè)的很好的例子。
Typically, these sorts of metal nodes are used to hold up large tent structures. In this case, it in was in the Hague, along a shopping center.
這個(gè)金屬連接節(jié)點(diǎn)通常被用于固定大的帳篷結(jié)構(gòu)。這是關(guān)于荷蘭海牙的一個(gè)大型購(gòu)物中心。
They used 1600 of the materials on the left. The difference is, by using the solution on the right, they cut down the number of steps from seven to one,
他們用了1600個(gè)左邊的節(jié)點(diǎn)，而用右邊這個(gè)節(jié)點(diǎn)的不同之處在于，他們將安裝步驟從7步減到了1步，
because the one on the left is currently welded, the one on the right is simply just printed.
因?yàn)樽筮叺倪@個(gè)是焊接而成的，而右邊這個(gè)是直接打印出來(lái)的。
And it was able to reduce waste to zero, cost less money and also, because it's made out of steel, can be eventually recycled at the end of its life.
這么做，可以實(shí)現(xiàn)零浪費(fèi)，還能降低成本，同時(shí)因?yàn)樗卿撝破罚院罂梢灾匦禄厥赵倮谩?/div>
Nature also is very effective at thrift. Think about it: nature has zero waste. Everything is useful for another process.
大自然在節(jié)約方面也是極其高效的，想一想：大自然不會(huì)生產(chǎn)任何垃圾，每一樣?xùn)|西都能物盡其用。
So, in this case, nanocellulose, which is basically one of the very fine building blocks of cellulose, which is one of the materials that makes trees strong,
例如納米纖維，它是纖維素極細(xì)微的組成部分，纖維素是能讓樹(shù)木如此堅(jiān)固的物質(zhì)之一，
