At stake are not only economic questions, such as the future growth of national wealth and new ways of managing workers, but also social balance questions, such as the proper role of work in one’s life, community engagement, and the importance of family and friends.
这不仅关乎经济问题，如未来国家财富的增长和管理员工的新方式，也关系到社会平衡问题，如工作在一个人的生活中的适当角色、社区参与以及家庭和朋友的重要性。

The use of plastics for mass production traces its roots to the 1860s and John Wesley Hyatt, a printer from Albany, New York. Hyatt was responding to the offer of a $10,000 reward to anyone who could come up with an alternative way of makingbilliardballs—which were, in those days, carved out of ivory, a commodity becoming in short supply. His solution was to form them by pumping a molten synthetic plastic called celluloid into a mould.
大规模生产塑料制品可以追溯到1860年代和约翰·韦斯利·海厄特，他是纽约州奥尔巴尼的一名印刷工人。当时，有人悬赏一万美元寻求制造台球的新方法，海厄特参与了竞逐。在那个年代，台球由象牙雕刻而成，而象牙越来越供不应求。他的解决方案是将一种叫做赛璐珞的合成塑料熔化并注入模具，然后制成台球。
Although Hyatt appears never to have received the prize, the process he invented, injection moulding, became the way in which most plastic items are made. At least they were until the emergence in the early 1980s of additive manufacturing, popularly known as 3D printing. Machines that can print things in plastic have become ever more capable, turning out objects ranging from toys to medical implants, and components for cars, drones and aircraft.
虽然海厄特最终似乎并没有拿到那笔奖金，但他发明的注塑成型工艺成了大多数塑料制品的制造方法。这种工艺一路延续，直到1980年代早期出现了增材制造——俗称3D打印。能用塑料打印物件的机器变得越来越实用，可打印的物品多种多样，从玩具到医疗植入物，再到汽车、无人机和飞机的部件。
One other advance is now within the making. bcn3d Applied sciences, a Spanish producer of threed printers, has developed a brand new type of plastic printing which it callsviscouslithography manufacturing (vlm). From an preliminary 500 corporations stated to be eager to attempt the concept out, bcn3d haswhittledthe quantity down to twenty giant producers from industries resembling carmaking, electronics and engineering.
另一个进展在制作方面。bcn3D应用科学是西班牙一家生产3D打印机的公司，这家公司研发了一种全新的塑料印刷技术，称为粘性光刻制造。bcn3d从最初500家急于尝试这一印刷技术的公司中筛选，最后范围缩小到20家大型生产商，涵盖汽车制造、电子和工程等行业。
3d printers could make plastic objects in a number of methods. One extensively used approach includes an extrusion head tracing strains of molten polymer onto a so-called construct plate. As soon as the primary layer is finished, the platestrikes downatad, a second layer is added on high of the primary, and so forth. More moderen machines challenge a sample of ultraviolet (uv) gentle right into a vat of photosensitive liquidresinto treatment and solidify the layers required to create an object. A construct plate then steadily pulls the item out of the vat.
3d打印机可以用多种方法制作塑料物品。一种广泛使用的方式是，用挤压头在一种名为构造板的表面上跟踪熔融聚合物的形变。翻译划线句，长按文末小程序码打卡，答案下期公布~更现代的机器将一种温和紫外线的材料直接放入装有光敏液体树脂的大桶中进行处理，并固化形成一个物体所需的各层。然后，构造板稳稳地把物体从桶中拉出来。
One good thing about printing in resins is that they produce finely detailed, high-quality plastic components. A downside is that they are often brittle. It’s potential to combine extra supplies into resins, to enhance energy, for example, or so as to add flexibility. However, a bit like including extra substances to a cake, this thickens the combination, which might make the resin tough to print.
用树脂打印的一个好处是，它们可以制作出精细、高质量的塑料部件。缺点是它们通常很脆。例如，将其他材料额外加入到树脂中可能可以增加强度，也有可能增加灵活度。然而，这有点像在蛋糕中加入其他材料，会让混合物变粘稠，从而可能很难打印出来。
