Japanese entrepreneurs are building businesses based on 3D printing, showing the sort of pioneering spirit Prime Minister Shinzo Abe hopes can revitalise a calcified economy. Whether these entrepreneurs can lay the foundations for a new era in Japanese products though may depend on whether Abe can tear down barriers in a wider business culture that shuns risk and supports the status quo.

GM1E53P1ND801 Children look a robotic fish in a tank at the London Aquarium October 6, 2005. Robot fish developed by British scientists are to be released into the sea off north Spain to detect pollution. The carp-shaped robots, costing 20,000 pounds ($29,000) apiece, mimic the movement of real fish and are equipped with chemical sensors to sniff out potentially hazardous pollutants, such as leaks from vessels or underwater pipelines. The robots to be used are bigger than those which were seen at the London Aquarium and they measure 1.5 metres (nearly 5 feet) long -- roughly the size of a seal.

Five robots, modelled after the official Olympic mascots, "the five friendlies" or "Fuwa", have been entertaining people at the shiny new terminal in Beijing for over a week. These robots are capable of reciting over 100 sentences in either Chinese or English. They can perform simple greetings in 12 languages, sing Olympic songs, give directions and recommend scenic spots for days out in the city. The Fuwa were created to embody natural characteristics of four of China's most popular animals -- the Fish, the Panda, the Tibetan Antelope, the Swallow and the fifth represents the Olympic Flame.
