Download or read book Process Structure Properties in Polymer Additive Manufacturing written by Swee Leong Sing and published by MDPI. This book was released on 2021-09-01 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Additive manufacturing (AM) methods have grown and evolved rapidly in recent years. AM for polymers is an exciting field and has great potential in transformative and translational research in many fields, such as biomedical, aerospace, and even electronics. Current methods for polymer AM include material extrusion, material jetting, vat polymerisation, and powder bed fusion. With the promise of more applications, detailed understanding of AM—from the processability of the feedstock to the relationship between the process–structure–properties of AM parts—has become more critical. More research work is needed in material development to widen the choice of materials for polymer additive manufacturing. Modelling and simulations of the process will allow the prediction of microstructures and mechanical properties of the fabricated parts while complementing the understanding of the physical phenomena that occurs during the AM processes. In this book, state-of-the-art reviews and current research are collated, which focus on the process–structure–properties relationships in polymer additive manufacturing.

Download or read book Polymer Based Additive Manufacturing written by Jonathan E. Seppala and published by . This book was released on 2020-08-25 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Additive manufacturing (AM) is a potentially disruptive technology, revolutionizing not only traditional industries but generating entirely new ones through rapid innovation, the democratization of manufacturing, and unprecedented freedom of design. Furthermore, the development of AM technologies has practical implications for economic growth, healthcare, national security, space exploration, and sustainability. For military and space agencies, AM offers the possibility to transform the traditional supply chain system through manufacturing at-point-of-demand, recycling, and indigenous sourcing of raw materials. Similarly, these concepts are being leveraged by remote communities across the globe through efforts such as Fab Labs, which provide low-cost access to manufacturing technologies. AM is transforming healthcare in unexpected ways: doctors and patients have access to high-quality physical 3D models generated directly from computerized tomography (CT) scans. These surgical guides have proved invaluable in surgical preparation and patient consent. In the lab, researchers are developing medical devices or implants which mimic the patient's physiology, are pre-loaded with therapeutics, and are replaced with the patient's cells through natural tissue repair pathways. Pushing the limits of resolution, multi-photon technologies, which allow subdiffraction-limited resolution, are revolutionizing the development of micro-optical components. Unfortunately, adoption of AM technologies by industry has been slow; and while there are numerous success stories and commercial adoption is steadily increasing, AM is hampered by weak parts, incomplete certification methods, and empirical materials development. Regulatory and standards bodies are working to update or develop new standards and policies to deal with the unique material and production issues posed by AM. Many of the challenges facing the industry stem from our limited understanding of structure-process-performance relationships. These challenges fall into many categories and require a broad range of skills to address. For the researcher, AM processes offer unique challenges in materials development, metrology, and modeling, as well as opportunities to combine all three. What makes a polymer printable? What process parameters are important? How should parts be tested? These are all active areas of investigation. This book was inspired by the 2017 ACS Symposium "Additive Manufacturing of Structures and Functional Devices: Materials, Methods, Models, and Testing" and is supplemented by additional experts in the polymer AM field. The chapters discuss the technologies, measurement challenges, manufacturing opportunities, and fabrication potentials. We begin with an introduction to polymer additive manufacturing, identifying the measurement needs and technical challenges facing the industry. A chapter reviewing polymer powder bed fusion follows, providing a complete discussion on methods, materials, and applications. The bulk of the book covers thermoplastic material extrusion, with chapters discussing recycling-based feedstocks, composites materials, and multi-physics modeling linking experimentation and theory. Moving from thermoplastics to conductive inks, a chapter on in situ monitoring and control of direct-ink-write provides a clear example of how theory and modern machine vision can be used to create a practical and responsive control system. The last chapter provides a state-of-the-art review of multi-photon printing, discussing methods, materials, and the stunning capabilities of the technique"--

Book excerpt: Shape Memory Composites Based on Polymers and Metals for 4D Printing is a thorough discussion of the physics and chemistry behind this developing area of materials science. It provides readers with a clear exposition of shape-memory-composite (SMC) preparation techniques for 3D and 4D printing processes and explains how intelligent manufacturing technology may be applied in fields such as robotics, construction, medical science, and smart sensors.

Polymers and metals and their roles in 4D printing are dealt with separately, and applications of 4D printing are treated in their own chapter. The different alloy compositions and nanoparticle fillers in polymer composites are examined in detail, along with the key mechanisms involved in their processing. Hybrid nanofillers and synergistic composite mixtures, which are either in extensive current use or have shown promising outcomes in the field of 4D printing, are thoroughly discussed. Differences between these novel SMCs and traditional metal alloys, organic and inorganic composites are presented, and means by which they can improve mechanical properties that are triggered by external sources like magnetic field, temperature, and pH of solvent, are set out. This book provides practitioners, industrial researchers, and scholars with a state-of-the-art overview of SMP/SMA synthesis, additive manufacturing, modification in synthesis of SMCs for 4D printing, and their likely future applications.
