From the earliest forms of technology such as spears and knives which led to more efficient hunting, to the advent of manufacturing during the industrial revolution, followed by various inventions such as light bulbs, computers and even cars over the 20th century, technological progress has vastly contributed to the development of our economies and subsequently our material and non-material living standards. Fast forward to today, we continue to see improvements in existing technology, from the latest computers to new inventions previously not even dreamed of, like solar panels and online shopping. In short technology is the result of expanding innovative ideas that build on existing ideas. We see this in cars, which were modelled off of steam engine mechanics, which themselves were built from pre-existing technologies (from basic metals to even the wheel). Given the increasing speed at which technology is progressing, one of the major concerns people have is how technological progress will impact jobs in the future.
Hailed by ‘The Economist’ as catalyst of ‘the third industrial revolution’, 3-D printing, also known as additive manufacturing, looks set to have a significant impact on manufacturing in the near future. What exactly is this technology, touted as the ‘next revolution in manufacturing’?
