Ehsan Toyserkani - Metal Additive Manufacturing

Chapter 8starts with a review of relevant historical background on material science. It then focuses on the comparison of conventional versus AM processes within the context of material properties. It discusses the fundamentals of solidification as well as factors affecting solidification in AM and phase transformation for different alloys used in metal AM.

Chapter 9explains the concept of Metal Matrix Composites (MMCs). It also covers applications of AM technology in the fabrication of MMCs and possible challenges. It also sheds some light on the differentiation of categories of MMCs in AM, e.g. ferrous matrix composites, titanium matrix composites, aluminum matrix composites, nickel matrix composites.

Chapter 10sheds some light on new design frameworks tailored to AM. It helps the reader to understand the importance of design rules and guidelines and how they differ between AM processes. It covers the theoretical framework supporting topology optimization, efforts toward including AM constraints in topology optimization models and a typical workflow of basic topology optimization in AM. It elaborates on the important terminologies that define lattice structures and helps the reader understand some practical lattice design methodologies. It also explains the significance and design strategies of support structures for the success of the printing process and product quality while improving the reader's understanding of design workflows for AM through case studies.

Chapter 11explains different classes of in‐situ sensing devices used for AM processes. It covers theories of some of the sensors used in AM, while shedding light on various applications of statistical approaches as quality assurance paradigms. It ends with fundamental and applications of machine learning techniques to AM and a case study.

Chapter 12is mainly concerned with safety regulations in the AM industry. A basic understanding of AM process hazards, hazardous materials in AM, and associated safety matters in laser‐based and electron beam AM techniques is covered. It also briefly explains human health hazards in AM and the comprehensive steps necessary for safety management.
