It is actually a reality today?that you can download products from the Web --?product data, I should say, from the Web --?perhaps tweak调整[twi:k] it and personalize [?p?:s?n?la?z] it?to your own preference or your own taste,?and have that information sent?to a desktop machine?that will fabricate制造[?f?br?ke?t] it for you on the spot地点，场所[sp?t].?We can actually build for you,?very rapidly迅速,?a physical物理[?f?z?kl] object物体.?And the reason we can do this?is through an emerging technology?called additive manufacturing制造业，工业[?m?nju?f?kt??r??],?or 3D printing. 现在已经成为现实?你可以从网上下载产品?严格地说，是产品的数据?然后可以根据自己的偏好进行个性化定制?然后可以根据自己的偏好进行个性化定制?把最终的信息发送到?一台桌面电脑上?然后电脑可以当场为您制作出产品。?我们可以为你?非常快捷地?制造出产品，?我们之所以能够这么做，?是因为我们通过一项新兴技术?这项技术叫做添加剂制造?或者3D打印技术 This is a 3D printer.?They have been around?for almost 30 years now,?which is quite amazing to think of,but theyre only just starting?to filter滤波器过滤;?透过[?f?lt?(r)] into the public arena表演场地，舞台[??ri:n?].?And typically通常[?t?p?kli], you would take data,?like the data of a pen here,?which would be a geometric几何[?d?i:??metr?k] representation表示[?repr?zen?te??n] of that product in 3D,?and we would pass that data with material?into a machine.?And a process过程;?工序[?pr??ses] that would happen in the machine?would mean layer by layer that product would be built.?And we can take out the physical product,?and ready to use,?or to, perhaps, assemble组装[??sembl] into something else. 这是一个3D打印机?它们已经有30年的历史了??真是不可思议?但是它们刚刚开始?进入到公众的视野里?一般来说，你需要数据?像这支笔的数据?这些数据是产品的3维几何表示?然后我们把数据和原料?放进一个机器里?机器会按照程序?一层一层地把产品造出来?然后我们就造出来了这个产品?马上就可以用?或者可以和其他组合在一起 But if these machines have been around for almost 30 years,?why dont we know about them?Because typically theyve been too inefficient,?inaccessible,?theyve not been fast enough,?theyve been quite expensive.?But today,?it is becoming a reality?that they are now becoming successful.?Many barriers are breaking down.?That means that you guys?will soon be able to access one of these machines,?if not this minute.?And it will change and disr
