This thesis investigates the optimisation and standardisation of production processes within COBOD International, a leading company in the field of construction 3D printing. The research addresses the challenges arising from the current configuration of the Production Department, where activities are characterised by a high degree of manual work, variability, and dependence on individual expertise. These conditions, while functional in the pioneering phase, risk becoming a bottleneck as the company expands and prepares to relocate to a new production facility. The study is structured into five chapters. The first two provide a literature review on the role of standardisation and continuous improvement, while the third chapter examines the principles and tools of Lean Manufacturing, with particular emphasis on Kaizen, PDCA, and Poka-Yoke.
