Abstract
<jats:p>This monograph examines the development and experimental validation of an integrated methodology for a closed-loop engineering process applicable to the creation and modification of unmanned platforms in the maritime domain. The main focus is placed on the systematic integration of 3D scanning, digital processing, additive manufacturing, and sensor system integration within a unified engineering process. The study analyzes the role of modern 3D technologies as tools for optimizing engineering processes in the fields of maritime security, defense, and applied research. The principal methods of 3D scanning, point cloud processing, and reverse engineering are discussed, as well as additive manufacturing technologies and materials, with an emphasis on their applicability in maritime environments. The approach is validated through the development of real prototypes of an unmanned vehicle and an autonomous maritime buoy, as well as through the analysis of technological and operational limitations related to their use. The scientific contribution consists in the adaptation and combination of existing methods and technologies into an integrated engineering framework aligned with the specific requirements of the maritime environment. The practical significance of the research is reflected in the potential for rapid prototyping, modification, and repair of unmanned platforms, as well as in supporting activities related to maritime security and engineering training.</jats:p>
