Abstract: With the development of the automotive industry, consumers have increasingly high requirements for automotive products, paying more attention to the aesthetics, high-end, and comfort of automobiles. In terms of automotive interior, the application of wrapping is also becoming increasingly widespread. For models with low planned production capacity, traditional process solutions may result in cost waste. Adopting advanced processes such as additive manufacturing (3D printing) can achieve low-cost production of small batch wrapping parts. In order to meet the performance requirements of the parts, the wrapping process for additive manufacturing (3D printing) parts is explored, and the application of the wrapping process in the automotive industry, the wrapping process based on additive manufacturing, and the production method of plastic substrates are analyzed. The results show that in the process of using 3D printing technology to achieve small batch production of wrapping parts, selecting the appropriate 3D printing method and printing materials can ensure that the appearance, size and product performance of the parts meet the relevant technical requirements.
