The '3Doodler' can help students become interested in science, technology, engineering and math (STEM) and introduce them to the concept of 3D printing. The '3Doodler' - designed by WobbleWorks, an American start-up originally funded through Kickstarter - is essentially the "hot end" of a 3D printer, which uses heated plastic that cools instantly, allowing one to "draw" upwards and in every direction. The 3Doodler was among the items on display at the recent Dubai Airshow's 3D-printing pavilion, where its designers showcased the massive, colourful designs that the pen makes possible.
