Suck My Trend - 3-D printing is a recently developed technology that is set to revolutionize the production of products. 3-D printers were once part of the science fiction world but have become reality and are beginning to pop up everywhere. They are appearing in a diverse number of places from the desks of home-hobbyists to research centers for Air Force drones. They also range massively in price from around $400 to more than $500,000 so suit every need. They work by extruding layer upon layer of plastic or other materials such as metal to create 3-D products with moving parts. Although in many ways these appear to be completely amazing, these printers could also lead to massive job losses.
