<P> 3D printing is one area that would be able to take advantage of economies of scope, as it is an example of same equipment producing "multiple products more cheaply in combination than separately". </P> <P> If a sales team sells several products, it can often do so more efficiently than if it is selling only one product because the cost of travel would be distributed over a greater revenue base, thus improving cost efficiency . There can also be synergies between products such that offering a range of products gives the consumer a more desirable product offering than would a single product . Economies of scope can also operate through distribution efficiencies--i.e. it can be more efficient to ship to any given location a range of products than a single type of product . </P> <P> Further economies of scope occur when there are cost savings arising from byproducts in the production process, such as when the benefits of heating from energy production having a positive effect on agricultural yields . </P>

Which one of the following is not an example of economy of scope
