Redefining supply chain and related aspects through integration of 3D printing technology

The present work evaluates the transformational impact of 3D printing technology in recreating the automotive industry's supply chain. The research indicates 3D printing as one of the many revolutionary changes the technology provides, its role, particularly within product complex customization, and fast prototype creation. The methodology is built on a mixed-methods approach, where quantitative analysis and in-depth surveys, interviews, telephonic conversations, and case studies with the representatives of the 3D printing industry are being implemented. The survey includes the experiences and knowledge of car manufacturers and components suppliers. It focuses on their approaches to introducing 3D printing, its benefits, and the constraints this technology imposes on operations. It studies 3D printing technology and benefits like improved flexibility in car manufacturing. It makes it easy for car makers to be application-oriented in response to changes and adapt their products to the market and customer preferences. The technology further reduces time consumption and reduces inventory costs via short lead time. However, there are several hurdles, like appropriate technological proficiency, tireless investments upon startup, and the inability to gain a lot of various materials and perform the operations very fast. The present research carries invaluable information for industry practitioners and policymakers in the automotive industry. It suggests that including 3D printing helps provide flexibility to an existing supply chain, adopts new technologies, and gradually steers the industry to higher sustainability levels. Spearman's rank correlation, hypothesis, regression, and logistics regression analyses establish the correlation between 3D printing and the supply chain. As a result, in this study, we have given arguments that explain why the industry should settle for 3D printing over conventional manufacturing methods. We propose approaches for adopting 3D printing technology within the supply chain of the automobile industry.
