Hybrid Additive Manufacturing: Techniques, Applications and Benefits explains the fundamentals of hybrid AM, definitions, classifications, and principles, as well as key techniques of hybrid AM, its applications, design guidelines, and benefits, with emphasis on key aspects of the system integration process. The core of this subject is in describing how to overcome inherent processing limitations of layer-by-layer AM through the integration of secondary post-processing such as machining or heat treatment. As a result hybrid AM plays a critical role in accelerating the adoption of AM in established design and manufacturing activities. The applications of hybrid AM in both metals and polymers are discussed in this book, as are geometrical dimensioning and tolerancing, material property enhancement, non-traditional surface finishing, in-situ sequential hybrid processing, and integrated process planning. This book will serve not only as an introduction to hybrid AM but also as a handbook for researchers and engineers in mechanical, manufacturing, industrial, electronics, and materials science, thanks to its interdisciplinary approach and detailed case studies. Explains how hybrid manufacturing processes can be used to achieve enhanced material properties and functionality Describes the significance of hybrid additive manufacturing to different parts of the process chain Uses case studies to show how innovative companies are using this technology, how they have overcome challenges they encountered, and the benefits they have experienced

Automation in production of 3D printed parts, hybrid additive and subtractive machines, and post-processing of 3D printed parts are rapidly growing fields. Given the numerous advancements in the 3D printing industry as reported in this thesis, the lack of availability of a Do It Yourself (DIY) and low-cost hybrid additive and subtractive unit is identified and tackled. This thesis covers the mechanical design of a low-cost DIY, hybrid additive and subtractive unit using a robot arm to remove the 3D printing support structures. Since the removal of printed support structures has not been investigated in the scientific literature, in a first step, different cutting tools and speeds were analyzed with a hand-held Dremel 4000 power tool with regard to cut quality and cutting forces. An off-the-shelf tool bit, a High-Speed steel cutter, at 15000 rpm yielded the best results. Furthermore, a hybrid machine was conceptualized, consisting of additive and subtractive subsystems. The constraints are a working volume of 6 cubic inches and costs below $5000. The additive system is based on following components: X, Y and Z Motor Holders, Filament Holder, and 3D Printing Arm, which can be printed by the DIY user, and off-the-shelf hardware like NEMA 17 stepper motors. The subtractive system is based on the following components: Motor Holder, Linkbot Mounting Interface, and Connector Arm, which are also designed to be 3D printed by the DIY users. For both subsystems, the off-the-shelf parts are specified, and technical drawings for 3D printing and assembly are provided. The critical 3D printed parts are analyzed with regard to their maximum distortion and strength during operation.

This book helps fill that gap. Additive Manufacturing: Applications and Innovations presents case studies of commonly used AM technologies with basic numerical problems for better understanding. It also includes hybrid processes and 4D printing applications, which currently are not offered in other AM books. Features Offers solved and unsolved problems in additive manufacturing Provides an understanding for additive manufacturing per international standards Includes case studies for better understanding of the individual processes Presents a review of specific technology highlights Introduces future research directions, mainly in 4D printing applications
Additive manufacturing (AM) is one of the manufacturing processes that warrants the attention of industrialists, researchers and scientists, because of its ability to produce materials with a complex shape without theoretical restrictions and with added functionalities. There are several advantages to employing additive manufacturing as the primary additive manufacturing process. However, there exist several challenges that need to be addressed systematically. A couple such issues are alloy design and process development. Traditionally alloys designed for conventional cast/powder metallurgical processes were fabricated using advanced AM processes. This is the wrong approach considering that the alloys should be coined based on the process characteristics and meta-stable nature of the process. Hence, we must focus on alloy design and development for AM that suits the AM processes. The AM processes, however, improve almost every day, either in terms of processing capabilities or processing conditions. Hence, the processing part warrants a section that is devoted to these advancements and innovations. Accordingly, the present Special Issue (book) focuses on two aspects of alloy development and process innovations. Here, 45 articles are presented covering different AM processes including selective laser melting, electron beam melting, laser cladding, direct metal laser sintering, ultrasonic consolidation, wire arc additive manufacturing, and hybrid manufacturing. I believe that this Special Issue bears is vital to the field of AM and will be a valuable addition.

This book provides a wealth of practical guidance on how to design parts to gain the maximum benefit from what additive manufacturing (AM) can offer. It begins by describing the main AM technologies and their respective advantages and disadvantages. It then examines strategic considerations in the context of designing for additive manufacturing (DfAM), such as designing to avoid anisotropy, designing to minimize print time, and post-processing, before discussing the economics of AM. The following chapters dive deeper into computational tools for design analysis and the optimization of AM parts, part consolidation, and tooling applications. They are followed by an in-depth chapter on designing for polymer AM and applicable design guidelines, and a chapter on designing for metal AM and its corresponding design guidelines. These chapters also address health and safety, certification and quality aspects. A dedicated chapter covers the multiple post-processing methods for AM, offering the reader practical guidance on how to get their parts from the AM machine into a shape that is ready to use. The book’s final chapter outlines future applications of AM.

Additive manufacturing (AM) of metals and composites using laser energy, direct energy deposition, electron beam methods, and wire arc melting have recently gained importance due to their advantages in fabricating the complex structure. Today, it has become possible to reliably manufacture dense parts with certain AM processes for many materials, including steels, aluminum and titanium alloys, superalloys, metal-based composites, and ceramic matrix composites. In the near future, the AM material variety will most likely grow further, with high-performance materials such as intermetallic compounds and high entropy alloys already under investigation. Additive Manufacturing Applications for Metals and Composites is a pivotal reference source that provides vital research on advancing methods and technological developments within additive manufacturing practices. Special attention is paid to the material design of additive manufacturing of parts, the choice of feedstock materials, the metallurgical behavior and synthesis principle during the manufacturing process, and the resulted microstructures and properties, as well as the relationship between these factors. While highlighting topics such as numerical modeling, intermetallic compounds, and statistical techniques, this publication is ideally designed for students, engineers, researchers, manufacturers, technologists, academicians, practitioners, scholars, and educators.
