This research explores the customization potential of ceramic extrusion by means of integrating CNC fabrication tools into current industrial ceramic extrusion lines. In order to support this approach, we designed and built two wall prototypes made of 700 extruded ceramic pieces. The pieces were produced using a single extrusion die and were cut to custom lengths and angles using CNC disk cutters to produce a total of 38 unique pieces. We introduce the motivation behind our work, present a three-stage design workflow for the design of this type of ceramic system, and show our built prototype.
