Olhem para o ecossistema:

"While most innovation for the manufacturing value chain has been driven by large conventional companies in a BtoB-setting, innovation in the digital value chain has been the result of a growing community of “Makers”, i.e. hobbyists, private consumers, and small start-ups interesting in utilizing AM [Additive Manufacturing] for local manufacture of objects for own use. This community has been very active in developing 3D models, creating an infrastructure for sharing these models digitally in online repositories (like Thingiverse or Google 3D Warehouse), selling 3D printed products on marketplaces, and even developing their own 3D printers for home usage. We argue that this Maker community has become a kind of “economic lab”, experimenting with different designs of value chain and business models, which  also provides insight for large scale industrial use of AM.
...
A distinctive feature of AM is frequently emphasized in the popular press: its ability to be placed locally next to potential users, up to the point of locating a 3D-printer into a user’s home.
...
Local production may be foremost attractive for innovating users. Past research has shown that users have been the originators of many industrial and consumer products.
...
Users can turn to advanced AM technologies to produce smaller series of products for themselves and their peers. User innovation then will be supplemented by user manufacturing, which we define as the ability of a user to easily turn her design into a physical product. By eliminating the cost for tooling (moulds, cutters) and switching activities, AM allows for an economic manufacturing of low volume, complex designs with little or no cost penalty. AM further enables multiple functionality to be manufactured using a single process, including also secondary materials (like electrical circuits), reducing the need for further assembly for a range of products.
...
With this production capacity available, user manufacturers may turn into user entrepreneurs. Recent research found that innovating (lead) users frequently engage in commercializing their developments.
...
Once user entrepreneurs started commercializing their products, they may have a competitive advantage against established manufacturers as they obtain better local knowledge on customer demand, allowing them to design products closer to local needs. Especially in a situation where customer demand is heterogeneous and customers place a premium on products fitting exactly to their needs, local producers may outperform established manufacturers of standard goods. The benefits of offering a better product fit may outweigh disadvantages in manufacturing costs due to economies of scales achievable by the established firm with its standard offering. A system of entrepreneurial user manufacturers could have large impact on the market structure in a given industry.
.
Interestingly, entrepreneurs do not need to acquire their own manufacturing resources. Instead, they might use the existing AM ecosystem and rely on a 3D printing service (like Shapeways, as described before) or contract manufacturer to produce their goods—the interface is rather simple: the product’s 3D design file."
