The visible surfaces of materials work to organize and structure interaction, perception and performance. In MS4 students develop material prototypes using hybrid processes, manual shop work and digital fabrication. Topics and techniques in contemporary digital fabrication are presented to students through a series of readings, short exercises, and precedent studies. Students are trained in the use of rapid prototyping, laser-cutting, and CNC milling. Students will work individually on a series of small fabricated models exploring the craft of digital fabrication through close attention to material properties and effects, machine precision, structure, and geometric logic.
