No Financial Times de dia 15 de Junho um artigo de Wolfgang Münchau sobre ... a impressão 3D
"In the 1960s Roy Amara, a Stanford computer scientist, observed that “we tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run”....Supply chain managers in industrial companies will be busy right now studying alternative sources that are more local. They may trade efficiency for robustness. They may be looking at automation. Back in February, they may not have seen the need to fix what did not seem broken. But now it is..A recent 3D printing industry survey found that companies are looking at the technology differently, with more of them now considering using it for end production rather than just prototypes..A German study in 2015 predicted that the economic impact of 3D printing would be to lower barriers to entry, making it easier for companies to serve different markets and cutting prices for consumers. It would constitute what economists call a positive supply shock....More localised production would also cut the cost of transport and contribute to the reduction in greenhouse gas emissions....There are downsides. Export-led growth has been the business model of developing countries. More localised manufacturing would hurt them. Automation will improve the employment prospects of some but reduce those of others. A mechanical or chemical engineer can perhaps retrain and find niches in other high-tech areas....Like many technological inventions of the past, this one could also give rise to new forms of inequality. Economies with strong high-tech investment such as the US and China would do well. European countries would probably not be at the forefront — to put it mildly — but there may be niches for those with a strong technological focus,"
