KeyMe does not actually use 3D printing; it cuts them out of blanks the “traditional” way, but uses the same kind of electronic design representation that a 3D printer would. In fact, I consider it a brilliant forerunner of the overall impact of 3D printing – making the occasional production of cheap copies of a specific item easy and available anywhere, anytime.
金钱成本（更不用说方便性了）是前往普通钥匙铺的成本的一部分——特别是在发生紧急状况时。KeyMe并没有真正使用3D打印；它只是用它们填补“传统”方式的空白，但使用了与3D打印机相同的电子设计表现形式。事实上，我认为它是3D打印全面影响杰出先行者——让特定物件的廉价复制品的偶然生产变得更加容易，随时随地都能进行。
