Book Description :

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

Book Description :

The term “hybrid” has been widely applied to many areas of manufacturing. Naturally, that term has found a home in additive manufacturing as well. Hybrid additive manufacturing or hybrid-AM has been used to describe multi-material printing, combined machines (e.g., deposition printing and milling machine center), and combined processes (e.g., printing and interlayer laser re-melting). The capabilities afforded by hybrid-AM are rewriting the design rules for materials and adding a new dimension in the design for additive manufacturing paradigm. This work focuses on hybrid-AM processes, which are defined as the use of additive manufacturing (AM) with one or more secondary processes or energy sources that are fully coupled and synergistically affect part quality, functionality, and/or process performance. Secondary processes and energy sources include subtractive and transformative manufacturing technologies, such as machining, re-melting, peening, rolling, and friction stir processing. Of particular interest to this research is combining additive manufacturing with laser shock peening (LSP) in a cyclic process chain to print 3D mechanical properties. Additive manufacturing of metals often results in parts with unfavorable mechanical properties. Laser shock peening is a high strain rate mechanical surface treatment that hammers a work piece and induces favorable mechanical properties. Peening strain hardens a surface and imparts compressive residual stresses improving the mechanical properties of the material. The overarching objective of this work is to investigate the role LSP has on layer-by-layer processing of 3D printed metals. As a first study in this field, this thesis primarily focuses on the following: (1) defining hybrid-AM in relation to hybrid manufacturing and classifying hybrid-AM processes and (2) modeling hybrid-AM by LSP to understand the role of hybrid process parameters on temporal and spatial residual stress development. A finite element model was developed to help understand thermal and mechanical cancellation of residual stress when cyclically coupling printing and peening. Results indicate layer peening frequency is a critical process parameter and highly interdependent on the heat generated by the printing laser source. Optimum hybrid process conditions were found to exists that favorably enhance mechanical properties. With this demonstration, hybrid-AM has ushered in the next evolutionary step in additive manufacturing and has the potential to profoundly change the way high value metal goods are manufactured.

Book Description :

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.

Book Description :

Additive manufacturing enables the aerospace industry to re-design metallic structural components for improved specific strength. Many structural components are equipped with complex sensing systems, for example, to probe structural health. This dissertation investigates hybrid additive manufacturing: processing of multiple materials using one or more additive manufacturing techniques. The research is directed toward ferroelectric oxides as the functional element and aerospace alloys as the structural component. The specific materials examined are ferroelectric oxide lead zirconate titanate (PZT) and aerospace alloys Inconel 718, Ti-6Al-4V, and 17-4 PH stainless steel. The objective is to develop a new processing strategy utilizing a dual hybrid additive manufacturing approach with material jetting of the ferroelectric oxide and powder bed fusion of the aerospace alloys. Chemical solution deposition of PZT 20/80 films on commercial metal foils and additively manufactured Inconel 718 substrates demonstrate feasibility of piezoelectric behavior on traditionally fabricated and additively manufactured metal surfaces. Promising dielectric and ferroelectric measurements are obtained through robust polarization-electric field hysteresis loops; however, prominent interfacial layers require processing optimization. Therefore, mesoscopic models of tetragonal PZT compositions on various alloy classes are generated in order to understand the role of thermal strains on dielectric, piezoelectric, and pyroelectric properties. The emanating Ashby plots suggest titanium and some iron-based alloys as suitable candidates for sensing systems, but as a whole, serve as a guide for materials selection for future applications of PZT on metallic substrates. Finally, the dual hybrid approach of inkjet printing of PZT 20/80 films on commercial metal foils and additively manufactured Ti-6Al-4V and 17-4 PH stainless steel allow direct patterning of functional elements onto structural components. The overall implications of structure-processing-property relationships pave a path for integrated functionality, and point toward the feats attainable by additive manufacturing.

Book Description :

In the past three decades, there has been an increasing focus of research efforts on the development and optimization of additive manufacturing processes. These additive manufacturing processes may use powder/liquid and solid based consumable materials. But up until now, little has been reported on hybrid processes, (such as processes that can use a combination of powder/liquid and solid based consumable materials) or smart consumables which may have controlled 4th dimensional capabilities. Additive Manufacturing for 4D Applications explores both autonomic and non-autonomic systems with different stimulus such as temperature, current, moisture, light, sound. In addition, the 5th dimensional aspect using more than one stimulus is outlined for additive manufacturing processes. It presents both an introduction to the basic understanding of hybrid processes, as well as exploring the physics behind the process (in the form of derivation and numerical problems). For the field engineer, applicable codes and standards for each hybrid process are provided. Lastly, case studies are included in each section and will provide the reader with a model to explore future research directions. Begins with the fundamentals of hybrid additive manufacturing process Presents a discussion of the physics behind the smart material functioning in hybrid additive manufacturing Includes real world case studies on 4D and 5D printing, as well as a look at the future research dimensions in 4D/5D printing

Book Description :

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.

Book Description :

A new method of manufacturing injection molds is proposed to take advantage of new hybrid additive and subtractive machine tools. The target model is discretized into a grid to use individual blocks as the substrate for additive manufacturing processes. Creation of an integrated cooling channel throughout the entire mold is accomplished by a cylindrical cutaway around the center of each block which when aligned produce a cooling channel between blocks. The blocks are held within an external frame while additive operations are performed to generate a continuous surface which is then finished by subtractive machining operations to achieve final geometric accuracy and surface finish. This method has advantages over both the traditional subtractive-only manufacturing of injection molds and more recent additive-only manufacturing techniques. The grid molding method allows creation of cooling channels superior to the drilled channels used in traditional methods, while also being much faster than the newer additive methods using powder bed selective laser melting. A functional prototype was manufactured using blocks and a frame made from NAK55 tool steel while the deposited material was H13 tool steel, allowing for easier machining of the substrate components while providing an extremely hard and wear resistant surface. Thermocouples were inserted into the resulting mold cavity as well as the existing traditionally manufactured mold cavity in order to measure temperatures during a test of 100 injection cycles using identical process conditions to compare cooling efficiency. A significant improvement in cooling efficiency is achieved by the new method.

Book Description :

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. The main benefit of the book is its highly practical approach: it provides directly applicable, “hands-on” information and insights to help readers adopt AM in their industry
