一项全新的制造技术将如何改变世界18世纪后期的工业革命使得商品的批量生产成为可能,由此以当时无人能够想象的方式创造了改变经济——以及社会——的规模经济效益。现在,一项反其道而行之的新制造技术出现了。三维打印让制造单一物品变得与生产大量物品一样便宜,并由此逐渐削弱规模经济效益。这可能对世界产生与工厂的出现同样深远的 How a New Manufacturing Technology Will Change The world’s industrial revolution of the late eighteenth century made it possible to mass-produce goods, thereby creating the economies of scale of changing economies-and societies-in such a way no one was able to imagine then. Now, a new manufacturing technology that has taken the opposite direction has emerged. Three-dimensional printing makes manufacturing a single item as cheap as producing a large number of items and, as a result, reduces economies of scale. This may be as far-reaching as the emergence of the factory in the world
