Technology Tuesday: 3d Pens

In a world where 3D printing already allows us to use a printer to create anything we can dream up, 3Doodler takes things a step further by letting you draw solid sculptures in real time.  

This new 3D Printing Pen called 3Doodler lets you wave your pen through the air - and a trail of heated gel - the "ink" - will follow.  Once the gel hits the air, it cools, freezing in midair.  Though the pen hasn't hit the shelves quite yet, kids reading Crockett Johnson's Harold and the Purple Crayon and dreaming of their drawings coming to life may be one step closer to seeing their dreams become reality.
