The 3D Printing Pen from 3Doodler extrudes heated plastic, which quickly cools and solidifies into a stable structure. Suitable for both right- and left-handed use, the pen can be used to draw flat forms on paper that can be peeled off, or it can draw 3D objects in mid-air. Because 3Doodler filament adheres to other plastics, you can also use it to decorate and personalize items, weld together traditionally-printed 3D objects, or repair small plastic items.
The pen allows you to adjust the settings for either ABS or PLA filaments, both of which are supported by the 3Doodler, but require different temperatures to extrude. Two buttons also allow you to control the speed at which the plastic is extruded, which will affect the thickness and properties of the resulting doodle.
