3D Printer Pen
A $99 pen that allows you to build a 3D structure in the air using melted, but rapidly cooled, plastic is to go on sale next year.
Called 3Doodler, the pen was developed under a Kickstarter project which asked for $30,000 and received $2.3 million.
The inventors took the extruder from a 3D printer and put it into a pen – making a device that can build a 3D structure in the air.
The pen was developed by a company called WobbleWorks of Boston.
