Additive manufacturing (AM) is a fast-growing sector with the ability to evoke a revolution in manufacturing due to its almost unlimited design freedom and its capability to produce personalised parts locally and with efficient material use. AM companies, however, still face technological challenges such as limited precision due to shrinkage, built-in stresses and limited process stability and robustness. Moreover, often post-processing is needed due to high roughness and remaining porosity. Qualified, trained personnel are also in short supply. In recent years, there have been dramatic improvements in AM design methods, process control, post-processing, material properties and material range. However, if AM is going to gain a significant market share, it must be developed into a true precision manufacturing method. The production of precision parts relies on three principles: Production is robust (i.e. all sensitive parameters can be controlled). Production is predictable (for example, the shrinkage that occurs is acceptable because it can be predicted and compensated in the design). Parts are measurable (as without metrology, accuracy, repeatability and quality assurance cannot be known). AM of metals is inherently a high-energy process with many sensitive and inter-related process parameters, making it susceptible to thermal distortions, defects and process drift. The complete modelling of these processes is beyond current computational power, and novel methods are needed to practicably predict performance and inform design. In addition, metal AM produces highly textured surfaces and complex surface features that stretch the limits of contemporary metrology. With so many factors to consider, there is a significant shortage of background material on how to inject precision into AM processes. Shortage in such material is an important barrier for a wider uptake of advanced manufacturing technologies, and a comprehensive book is thus needed. This book aims to inform the reader how to improve the precision of metal AM processes by tackling the three principles of robustness, predictability and metrology, and by developing computer-aided engineering methods that empower rather than limit AM design. Richard Leach is a professor in metrology at the University of Nottingham and heads up the Manufacturing Metrology Team. Prior to this position, he was at the National Physical Laboratory from 1990 to 2014. His primary love is instrument building, from concept to final installation, and his current interests are the dimensional measurement of precision and additive manufactured structures. His research themes include the measurement of surface topography, the development of methods for measuring 3D structures, the development of methods for controlling large surfaces to high resolution in industrial applications and the traceability of X-ray computed tomography. He is a leader of several professional societies and a visiting professor at Loughborough University and the Harbin Institute of Technology. Simone Carmignato is a professor in manufacturing engineering at the University of Padua. His main research activities are in the areas of precision manufacturing, dimensional metrology and industrial computed tomography. He is the author of books and hundreds of scientific papers, and he is an active member of leading technical and scientific societies. He has been chairman, organiser and keynote speaker for several international conferences, and received national and international awards, including the Taylor Medal from CIRP, the International Academy for Production Engineering.

Freedoms in material choice based on combinatorial design, different directions of process optimization, and computational tools are a significant advantage of additive manufacturing technology. The combination of additive and information technologies enables rapid prototyping and rapid manufacturing models on the design stage, thereby significantly accelerating the design cycle in mechanical engineering. Modern and high-demand powder bed fusion and directed energy deposition methods allow obtaining functional complex shapes and functionally graded structures. Until now, the experimental parametric analysis remains as the main method during AM optimization. Therefore, an additional goal of this book is to introduce readers to new modeling and material's optimization approaches in the rapidly changing world of additive manufacturing of high-performance metals and alloys.

The beginning of the chapter is devoted to methods of receiving of metal powders-initial components for metal additive manufacturing. Initial materials are very important part of manufacturing, because their quality has an influence on stability of production process and quality of final product. There are various methods of metal powder synthesis. They may be separated conventionally on physical-chemical and mechanical ones. The physical-chemical methods are associated with physical and chemical transformations, and chemical composition and structure of the final product (metal powder) significantly differ from raw materials. The mechanical methods include various types of milling processes and jet dispersion melts by high pressure of gas or liquid (atomization). It is shown that the typical methods of quantitative estimation of powdered materials and some parameters for alloys that already were used in additive technologies. The next theme of the chapter is a review of additive technologies, initial materials for that is metal powders. At this moment, there are three main technologies that have found wide use for the production of metal parts from metal powders: binder jetting, directed energy deposition, and powder bed fusion. Each of them has unique peculiarity, advantages, and limitations that will be presented in the chapter.

Metal additive manufacturing (MAM) is finding its way into mainstream manufacturing. Currently the approach when using MAM in industry is to empirically determine appropriate processing parameters. Once obtained no further changes are made and printers are dedicated to the particular part and material to build them with traditional sacrificial test builds to determine quality of the metal 3D printed part. The problem is that by taking this approach you now constrain this powerful technology. If it is possible to develop a basic understanding of the relationships between the amount of energy needed to build a part and the associated conditions required then it will enable metal additive manufacturing to e build any part with any material on any system without having to worry about quality. Before this can be achieved it is necessary to understand what the key metrics are that influence the metal additive manufacturing parts properties. Previous studies on process parameters and their impact on the microstructure are often limited to single wall samples and does not provide robust data. The aim of this Thesis is to create a universal design of experiment for determining optimal processing parameters in metal additive manufacturing. By creating this DOE we can then understand the relationships with respect to the amount of energy required to achieve a given microstructure. In order to show this DOE is applicable and repeatable, the experiment will be applied on different laser power levels and results will be studied.
