Depois de "Ponto de vista", onde escrevi:

"Proponho outra abordagem, ir ao fim da linha, ao utilizador final e pensar: "O que é que será melhor para ele?". Isso é que vai ditar a evolução do ecossistema da procura,"

 encontro "You Are Probably Underestimating The Value Of At-Home 3-D Printing":

"Few people expect 3D printing--particularly in the home--to be as much of a revolution as it actually could be.
.
But the household economics of 3D printing, when considered more academically, suggest that relatively low-tech 3-D printers in the home of the average user can equate to incredible high cash savings for a family's bottom line.
...
The results may surprise you. 3-D printing the 20 chosen objects cost only about $20 and took around 25 hours. In a store, depending on the quality of the products chosen, the same items would cost between $300 and about $2,000. Assuming the average family would only print about 20 objects of similar practical utility in a year, a printer like a RepRap would pay for itself in savings in just about four years.
...
Developments of this type mean that 3-D printing at home, where one either creates an object to print, finds a version online, or scans a pre-existing object that you perhaps intend to replace, is already an economically sensible proposition. Then take this idea and imagine what it would mean if your local corner store had a printer, even if your home didn't?"
