Within architecture the joint is an integral part of a buildings dialogue with its users and audience. Steel joints allow for the extension of members and fundamental changes between column and beams. However, due to the limitation of traditional metal fabrication which caters for CAD made design. Highly parametric and computational informed designs are constrained by the conditions of mass production. Where high output low cost, vice versa, limiting the highly variable nature of geometrical informed individual joint. This research focuses on the fabrication of computational informed architectural steel connection in combination with non-linear geometric slicing and 6-axis robotic wire arc additive manufacture (WAAM). Aiming to optimise the aesthetic opportunities and practical fabrication of large scale steel architectural joints within industrial timber buildings. Currently, there exists a disconnect between the dialogue of metal joints and their digital informed surroundings. The two methods of non-linear slicing, member multi-directional slicing and cylindrical on member fabrication, aims to allows for a metal joint, to both be a function of computational inform data along with the additive fabrication process of WAAM.
