Thanks to USF engineering & research scholarships, I designed & fabricated a ceramic extrusion 3-D printer, which stands nearly 9 ft tall with a clay capacity of 80 lbs. Unlike common printers, this uses polar coordinates to determine positioning, meaning the circular base rotates to define the X & Y positioning. The purpose of the rotating base was to further mimic traditional ceramic practices such as pottery wheels while also exploiting the materials capability of uniform drying.
