3D printing started as a niche activity. It was for engineers and developers. However, in recent years 3D printing is reaching new groups – appearing in medicine, education, and even in average, everyday homes.
Today, there are 3D printers that can print with plastic, nylon, wood, cement and even candy. There are hand held 3D pens, called the 3Doodler, that allows both children and adults to start experimenting with 3D printing, there are even houses all over the world that have been built by a 3D printer.
