Amazon leverages its existing shipping and logistics knowledge and applies it to a new cloud resource, a 3D Printer.
Using Amazon’s platform, a user can connect through Amazon’s cloud services, lock a shared cloud resource, a 3D printer, feed the printer one of several formats: 3D blueprint, 3D digital scan, or industry spec file format. The object is then printed out, and shipped using Amazon’s shipping logistics engine.
Make the object you want and Amazon will ship it to you. How much does it cost? Cost of materials used to produce the object is quantified and charged, in addition to a cloud [resource] usage fee, and potentially discounted shipping based on Amazon’s current scale.
As the service is matured, design tools, basic and advanced, will be provided to produce your designed object. Only your imagination, and capability to express it limits your ability along with Amazon to deliver your products.
At some point, a seller can have a storefront, where objects can not only be shipped, but build on demand as well. For example, circuit boards can be sold now, with the above engine and service, from a seller with the proper schematics.
