Nolen Bruner, Clearfield County Career and Technology Center Drafting and Design student from Curwensville Area High School, is learning the basics of the 3D printer in the Drafting and Design program. Students create images on their computer and send it to the 3D printer.  A 3D printer essentially works by extruding molten plastic through a tiny nozzle that it moves around precisely under computer control. It prints one layer, waits for it to dry, and then prints the next layer on top.3D printing is a way of creating three dimensional (3D) solid objects. 3D printing is done by building up the object layer by layer.
