Media (R)evolutions: The 3D printing revolution

New developments and curiosities from a changing global media landscape: People, Spaces, Deliberation brings trends and events to your attention that illustrate that tomorrow's media environment will look very different from today's, and will have little resemblance to yesterday's.

3D printing, also known as "additive manufacturing", is changing the way products are created and reproduced.  It makes it possible to create a part from scratch in just hours and allows designers and developers to experiment with new ideas or designs without extensive time or assembly expenses.

Using a 3D computer modeling program or a 3D scanner (which makes a 3D copy of an object for a 3D modeling program), designers can now create or reproduce items for 3D printing. Once the design or copy of the object is prepared, the 3D modeling program slices it into hundreds or thousands of horizontal layers. This model is then uploaded in the 3D printer, which creates the object by printing layer upon layer of material. Each layer is blended together, resulting in one three-dimensional object.

These are some of the views and reports relevant to our readers that caught our attention this week.


2014 Human Development Report - Sustaining Human Progress: Reducing Vulnerabilities and Building Resilience
UNDP
As successive Human Development Reports (HDRs) have shown, most people in most countries have been doing steadily better in human development. Advances in technology, education and incomes hold ever-greater promise for longer, healthier, more secure lives. But there is also a widespread sense of precariousness in the world today—in livelihoods, in personal security, in the environment and in global politics. High achievements on critical aspects of human development, such as health and nutrition, can quickly be undermined by a natural disaster or economic slump. Theft and assault can leave people physically and psychologically impoverished. Corruption and unresponsive state institutions can leave those in need of assistance without recourse.
 

The State of the State
Foreign Affairs
The state is the most precious of human possessions,” the economist Alfred Marshall remarked in 1919, toward the end of his life, “and no care can be too great to be spent on enabling it to do its work in the best way.” For Marshall, one of the founders of modern economics and a mentor to John Maynard Keynes, this truth was self-evident. Marshall believed that the best way to solve the central paradox of capitalism -- the existence of poverty among plenty -- was to improve the quality of the state. And the best way to improve the quality of the state was to produce the best ideas. That is why Marshall read political theorists as well as economists, John Locke as well as Adam Smith, confident that studying politics might lead not only to a fuller understanding of the state but also to practical steps to improve governance.
