A crowdfunding campaign on Kickstarter.com for a foldable 3D printer that can print a variety of materials has been launched by the Maastricht start up, By Flow. Offered with a wide range of easily exchangeable extruders, the Focus can print with standard materials, including as PLA, ABS, wood and nylon, but also with bio-rubber, bronze, ceramics and silicon. The printer can also print edible materials, such as chocolate.
