The craft of carpentry relies on joinery: the connections between pieces of wood to create multipart structures. In traditional woodworking, joints are limited to the manual chisel skills of the craftsperson, or to capabilities of the machines, which favorite 90° or 180° angle joints with no more than two elements. We contribute an interactive design process in which joints are generated digitally to allow for unrestricted beam connectors, then produced from Nylon-12 using selective laser sintering (SLS) 3D printing. This work exemplifies the potential of Digital Joinery to enhance carpentry by incorporating a hybrid and interactive level of design sophistication and affordances that are very hard to achieve with traditional skills and tools.
