Advantage of a manufacturing complex objects without increasing costs. 3D printer to create a complex shape of the goods does not consume more than the cost of printing a simple box.
Advantage of 2 need not assemble. 3D printing enables integrated molding parts, saving on the cost of labor and transportation.
Advantage 3 zero time delivery. 3D printer can print on demand, to minimize the cost of long-distance transport.
Advantage 4 design space is infinite. 3D printers may even produce currently only exists in nature shape.
5 advantages of zero skill manufacturing. 3D printer can produce in remote environments or extreme conditions.
Advantage 6 does not occupy space, portable manufacturing. 3D printers can move freely, can be made bigger than their own items.
Advantage 7 reduce waste byproducts. 3D printing wasted little time making metal.
Advantage 8 exact physical copy. By 3D scanning technology and printing technology, we can accurately scan, copy entities.
