This text defines and covers different themes of post-processing techniques based on mechanical, chemical/electrochemical, and thermal energy. It will serve as an ideal reference text for senior undergraduate and graduate students in diverse engineering fields including manufacturing, industrial, aerospace, and mechanical. This book: covers the fundamentals and advancements in the post-processing techniques for additive manufacturing; explores methods/techniques for post-processing different types of materials used in additive manufacturing processes; gives insight into the process selection criteria for post-processing of additive manufactured products made from different types of materials; discusses hybrid processes used for post-processing of additive manufacturing parts; and highlights post-processing techniques for properties enhancement. The primary aim of the book is to give the readers a well-informed layout of the different post-processing techniques that range from employing mechanical energy to chemical, electrochemical, and thermal energy to perform the intended task.
