Things are getting interesting now that 3D printing is firmly on the radar.
Australia is a long way by sea or air for imported goods that arrive via transportation methods that cost time and fuel.
The cost to internally distribute goods throughout Australia is also high given our relatively small population and vast distances.
Import/Export and internal distribution costs are a significant cost component of our everyday items.
In a world where clothing, spare parts and potentially cars prices are potentially able to be manufactured by a suitable variation of a 3D printer, importers, wholesale and retail will all be touched in someway by 3D printing and its impact on distribution costs.
I found the article below interesting and thought you might as well.
