In the short run, this means greater efficiency and more and speedier recycling, happening locally rather than centrally. In the long run, 3D printing will allow more efficient use of physical resources and faster diffusion of the best designs, boosting living standards around the world.
从短期看，这意味着更高的效率和更快更好的循环利用，这些都将就地进行而不需要集中。从长期看，3D打印能提高实体资源利用效率和最佳设计的快速传播，提高全世界的生活水平。
