During the Mini Maker Faire in Toronto, visitors were able to see and test an undoubtedly most impressive innovation. The designers of the Hot Pop Factory have succeeded in combining Leap Motion technology with 3D printing. Thanks to the motion controller, visitors could draw in 3D with a simple hand gesture. The immediately created 3D file was sent to the printer to shape the object made "by freehand". A surprising and fun way to teach about 3D modeling and 3D printing.
