Three-D printing may be the next revolution in manufacturing. It's being used to make things in a completely different way from the mass production we've been familiar with ever since Henry Ford introduced the production line more than 100 years ago. Ford made a succession of almost identical items and that's what mass production still does today. 3D printing --or additive manufacturing as it's also known -- means that every product can be individual. It's a completely different way of thinking about manufacturing and costs little more to customise than it does to mass produce. This could potentially revolutionise manufacturing and businesses from top to bottom. Peter Day investigates. Producer CAROLINE BAYLEY

The government's aim is clear: by 2015, it wants Britain to have the best superfast broadband network in Europe. The internet is so essential to businesses, the argument goes, that the network over which internet traffic travels is becoming a vital part of the UK's infrastructure - as important as energy and roads. Right now, though, the country is a long way off from the target. Nowhere is this more apparent than in rural and remote areas of the country. In Norfolk, some small businesses are struggling just to get connected, much less plug into the high-speed network the government has pledged to help expand. A decade ago, internet access was a luxury for many small firms, but today it's essential. Orders are placed and received online, a website is a key marketing tool for all sorts of companies, and businesses must now file VAT returns via a website. This week on In Business, Peter Day evaluates the government's plans for broadband and finds out how close the UK is coming to a high-speed future online. Producer MIKE WENDLING

In some areas of rural China, traditional farming communities are transforming into something very 21st Century: internet shopping hubs. Leading the way is the village of Qing Yan Liu where, four hours south of Shanghai, local residents have created a world of bubble wrap and sticky tape. In the eyes of the Chinese Premier Xi Jinping this could be the future of rural China. He hopes that more and more small communities will copy what's happened in Qing Yan Liu - now dubbed 'China's No. 1 E-Commerce village'. It's hoped this will halt the flow of young people from rural China to the nation's cities, as they go in search of employment. Turning more small towns and villages into online shopping hubs would provide much needed jobs, and a reason for young people to stay at home, ensuring communities continue to survive rather than disappeard.
