Acerca da impressão 3D na produção

Daqui "Stratasys Primes Market for 3-D Revolution":

"WSJ: The prototype stage is such a big part of manufacturing. Is there any idea that [3-D printing] would move into the actual manufacturing stage itself?.
Mr. Jaglom: Well, we're already there, roughly 10% of all our applications are in the manufacturing sector.
.
There's actually a department at Stratasys that wakes up, goes to work every day and comes home at night thinking only of manufacturing and are measured on that."

Daqui "Adding and taking away":

"machine-tool makers are beginning to recognise 3D printing is going to be important in the factory of the future, not just for making models and prototypes (as is already happening) but also finished goods. The second is that additive manufacturing can complement subtractive manufacturing, as well as compete with it. If it work—and sells—the Lasertec could be the first of many such hybrids.
...
Subtractive manufacturing, in which a milling machine cuts shapes from metal blocks, may waste as much as 95% of the original material. By building something additively, even to only approximately the right shape, and then milling it, such wastage, the company reckons, can be reduced to around 5%.
Moreover, the object can be milled every time a new layer is added. This means smooth internal surfaces can be created inside what eventually becomes a solid object—something previously possible only if an item was made by joining together components that had been milled separately. With its ability to add and remove materials that include aluminium, brass, copper, stainless steel and numerous alloys, the hybrid Lasertec can also be used to repair items that are worn, or even broken. A case, perhaps, of old and new technologies coming together to produce more than the sum of their parts."

"we think the 3D printing market can grow from $2bn today to $9bn in 2020, a 20% CAGR, to become a sizeable market in capital goods and appliances. Our bull case sees a 34% CAGR to $21bn in 2020 – bigger than the injection moulding market today and about 25% of the size of the CNC machine industry.

3D printing – or additive manufacturing (AM)
...
3D printing – AM systems manufacturers believe it is no longer just a design tool …Perhaps the most controversial question on the industry today is the perceived crossover from prototyping into mainstream manufacturing. In a recent survey, leading independent consultants Wohlers Associates asked 31 manufacturers of professional-grade AM systems and 74 service providers what their parts were being used for. The perhaps surprising result is that the largest category (28%) is for functional parts, whereas prototypes for fit and assembly was 18% and for prototype tooling 11%. The implication here is that 3D printing is no longer just a ‘design tool’ and has already found its niche in mainstream manufacturing."

Vai ser interessante quando os consumidores perceberem o que pode ser feito por eles ou sob as suas indicações:

Acho sempre interessante, nestas análises, nunca colocarem a questão de as próprias indústrias serem afectadas por uma verticalização feita na óptica do consumidor ou de "novos artesãos".

Systeme D

Um texto interessante, um texto que também é sobre Mongo e a economia DIY:

"System D is a slang phrase pirated from French-speaking Africa and the Caribbean. The French have a word that they often use to describe particularly effective and motivated people. They call them débrouillards. To say a man (or woman) is a débrouillard(e) is to tell people how resourceful and ingenious he or she is. The former French colonies have sculpted this word to their own social and economic reality. They say that inventive, self-starting, entrepreneurial merchants who are doing business on their own, without registering or being regulated by the bureaucracy and, for the most part, without paying taxes, are part of “l’economie de la débrouillardise.” Or, sweetened for street use, “Systeme D.” This essentially translates as the ingenuity economy, the economy of improvisation and self-reliance, the do-it-yourself, or DIY, economy.
…
It is a product of intelligence, resilience, self-organization, and group solidarity, and it follows a number of well-worn though unwritten rules. It is, in that sense, a system. It used to be that System D was small—a handful of market women selling a handful of shriveled carrots to earn a handful of pennies. It was the economy of desperation. But as trade has expanded and globalized, System D has scaled up too. Today, System D is the economy of aspiration. It is where the jobs are.
…
A 2009 study by Deutsche Bank, the huge German commercial lender, suggested that people in the European countries with the largest portions of their economies that were unlicensed and unregulated—in other words, citizens of the countries with the most robust System D—fared better in the economic meltdown of 2008 than folks living in centrally planned and tightly regulated nations. Studies of countries throughout Latin America have shown that desperate people turned to System D to survive during the most recent financial crisis. This spontaneous system, ruled by the spirit of organized improvisation, will be crucial for the development of cities in the twenty-first century. The twentieth-century norm—the factory worker who nests at the same firm for his or her entire productive life—has become an endangered species. Even in China, where massive factories offer a better financial future than farming, they give no guarantee of job security. So what kind of jobs will predominate? Part-time work, a variety of self-employment schemes, consulting, moonlighting, income patching. By 2020, the OECD projects, two-thirds of the workers of the world will be employed in System D. There’s no multinational, no Daddy Warbucks or Bill Gates, no government that can rival that level of job creation. Given its size, it makes no sense to talk of development, growth, sustainability, or globalization without reckoning with System D.”
