Abstract
Additive manufacturing (AM) or three-dimensional (3D) printing has introduced a novel production method in design, manufacturing, and distribution to end-users. This technology has provided great freedom in design for creating complex components, highly customizable products, and efficient waste minimization. The last industrial revolution, namely industry 4.0, employs the integration of smart manufacturing systems and developed information technologies. Accordingly, AM plays a principal role in industry 4.0 thanks to numerous benefits, such as time and material saving, rapid prototyping, high efficiency, and decentralized production methods. This review paper is to organize a comprehensive study on AM technology and present the latest achievements and industrial applications. Besides that, this paper investigates the sustainability dimensions of the AM process and the added values in economic, social, and environment sections. Finally, the paper concludes by pointing out the future trend of AM in technology, applications, and materials aspects that have the potential to come up with new ideas for the future of AM explorations.
Highlights
Nowadays, the business markets look for up-to-date manufacturing technologies to find a quick response for high demands of variability, efficient supply chain, and optimized energy consumption.As a solution, Industry 4.0 uses the benefits of the integration of modern manufacturing technologies and information systems to promote production capabilities [1]
The goal of this paper is to classify the fundamental knowledge for investigating the current findings in materials and technologies, applications, and challenges surrounding additive manufacturing (AM), and provide a comprehensive study on AM’s role in smart manufacturing and industry 4.0
Case studies have shown that the material waste in AM is reduced by 40% compared to traditional methods and 95% to 98% of the leftover materials can be recycled [57]
Summary
The business markets look for up-to-date manufacturing technologies to find a quick response for high demands of variability, efficient supply chain, and optimized energy consumption. Industry 4.0 uses the benefits of the integration of modern manufacturing technologies and information systems to promote production capabilities [1]. In this context, smart manufacturing improves long-term competitiveness by optimizing labor, energy, and material to produce a high-quality product, and find a rapid response for variation in market demands and delivery time [2].
