For many years chairs are used to teach and develop students for digital fabrication machines, materials and methods of production. Students are required to design, prototype and manufacture a fully functional chair in 6 weeks using 3D Printers, laser cutters, and finally a CNC machine. The results and learning takes on a range of understandings from the fundamentals of structure to advanced methods.  This workshop has been taught at TU Delft in addition to MIT.
