Divided into two parts; Part I introduces the decision making situations in the manufacturing environment and presents decision making methods; Part II uses case studies to present the applications of these methods in real manufacturing situations. The journal publishes the advances in the processing of different kinds of materials by well-established and new Additive Manufacturing (AM) technologies. Additive Manufacturing (AM) is becoming increasingly important in various industries, particularly due to its freedom of design, functional integration and faster product development cycles. Future of Additive Manufacturing: Process Flow Exhibit, Global, 2015 Source: Frost & Sullivan . Additive manufacturing (AM), or 3D printing, technologies create three-dimensional parts from computer-aided design (CAD) models by successively adding material layer by layer until a physical part is created. Companies should now identify where it adds value and advantage – before their competitors do. (2009), "Application of correlati, Zhang, Y., Xu, Y. and Bernard, A. Additive manufacturing is one of the growing fields in manufacturing industry. endobj Additive manufacturing, also known as 3 D printing, creates p hysical objects from a geometrical representation by successive addition of material (I SO/PRF 17296 - 1 2015) . Aerospace. The solution derived from the study needs to be checked for practical feasibility by the decision makers. To the best of the authors’ knowledge, this is the first study to examine the relationship among investors’ rationality, self-attribution and overconfidence in the Indian context using a comprehensive survey. Producing a digital model is the first step in the additive manufacturing process.

Findings A numerical example regarding the comparison between Additive and Traditional Manufacturing processes is presented in order to demonstrate the applicability and the effectiveness of the proposed method. A standard part was designed and printed on each machine, and evaluated based on dimensional accuracy and surface finish. (2010), "Selection of rapid pro, Mahapatra, S.S. and Panda, B.N. Build time is a key issue in additive manufacturing, but even nowadays, its accurate estimation is challenging. Decision makers in the manufacturing sector frequently face the problem of assessing a wide range of options and selecting one based on a set of conflicting criteria. Multi-functionality can also be embedded in printed materials, including variable stiffness, conductivity, and more. All current studies follow a sequential decision process and focus on an “a priori” articulation of preferences approach. Find out the relationship between UX and user preference in the scope of common product (designed by designer), modularized product (co-design) and personalized product (design by user). The approach has been that of a literature survey. numerous advantages of an additive process for component fabrication. This study aims to review the existing methods for additive manufacturing (AM) process selection and evaluate their suitability for design for additive manufacturing (DfAM). This DSS accounted for various performance parameters, including tensile strength, dimensional accuracy, surface finish, and material cost. industries and agricultural producers, research institutions and non-governmental organizations. The research highlights the differences between AM units and suggests a method by which to ascertain the differences. additive manufacturing processes, the 3D CAD solid must be mathematically split into the same layers as those produced physically by the AM machine.
