3D Printing Pen

The principle that makes 3D pens work is very simple. Heat is used to melt plastic. Just like the simple glue gun, plastic filament is pushed through a heating chamber where it is melted. The temperature varies depending on the materials used to make the filament. The melted filament is then pushed through the extruder nozzle. The pen user moves the pen to create different shapes and figures. The melted plastic cools down and solidifies quickly once outside the pen, making the shape of the extruded filament permanent.
