3D Printing Pen?

Hey guys, the artist in me thought this was kinda cool, not sure if I would buy one, and with all the hype 3D printers are getting lately, I thought this was a neat twist.

trust me its not worth it. try one and you will see how crapy thay are

 

Technology is advancing at a scary rate.

 

True but not always best-developed before beeing seen on the market, this pen 3d thing would be one of those. 3d printers are however getting very good and something i have used when making prototype parts at work.

 

So its a glue gun with a fine tip?

 

Seems to be similar to what I trued to achieve by melting abs pipe with a blow torch, and forming shapes when I was a kid...
