But, in the future, if something breaks, you will be able to take it over to the 3D print shop to be reprinted. Better yet, the shop may be able to reuse the materials in your broken part – saving the costs and environmental burden of throwing things away, shipping them somewhere, and so forth.
比如，如今很多企业花大力气管理和储存备用件。每一处都需要存放数千件不同备用件，因为你不知道哪些备用件会在哪里用到。但是，在未来，如果有东西坏了，你只消把它拿到3D打印店打印一个即可。更妙的是，3D打印店或许能够再利用损坏部件的材料——减轻了把东西丢掉、运到某处等等的成本和环境负担。
