Taking the 093 model production as a starting point, this paper conducts an in-depth analysis of modern model making technologies. Through a detailed elaboration of the production process of 093 nuclear submarine model， including precise digital design using 3D modeling software in the early stage to determine the accurate proportion， suitable size and select appropriate materials， the use of 3D printing technology for rapid prototyping and fine model manufacturing， and the later processing procedures such as surface cleaning， polishing and coating protection， the characteristics and advantages of modern model-making techniques in digitalization， automation， material application and fine processing are comprehensively demonstrated. At the same time， the key role of this technology in improving the efficiency of model production， enhancing the reducibility and precision of models， as well as its application prospects and development trends in the field of model making are discussed， providing a useful reference for in-depth understanding of modern model-making techniques.
