3D With '3Doodler' Pen

The 3Doodler is a 3D pen that allows you to create 3D arts. It was developed by Peter Dilworth, Maxwell Bogue and Daniel Cowen of WobbleWorks, Inc. For long, the concept of 3D printing was thought of science fiction but over the last few decades 3D printers have become wide spread and are used for all sorts of
purposes from making simple 3D models to making complex body organs. However, the many might find the 3D printer hard to use because of its complicated software and hardware. But now a company called 3Doodler has introduced this amazing pen which allows us to draw freehand sketches in mid air.

It makes use of plastic thread made of Acrylonitrile butadiene styrene [ABS] and poylactic acid [PLA]. It uses these plastics by heating them and forcing them out though a nozzle which cool down almost instantly forming a solid stable structure. 

In many ways the 3Doodler works like a glue gun. A heating element heats the plastic and forces it out. The glue gun uses a hand pump which forces the glue out which makes it pretty messy to use. So the challenge for the team was to create a way to make the plastic flow out more steadily and smoothly. For this they used a motor which propels the plastic out smoothly.

The 3Doodler Create far exceeds the 127-degree F (53 degrees C) maximum temperature allowed for children's products, as set by the EU Toys Safety Directive. To solve this problem 3Doodler teamed up with material scientists and together developed a new types of plastic which was biodegradable and child friendly and which melts between 113 degrees and 122 degrees Fahrenheit (45 to 50 degrees C).
