Summary

Additive manufacturing (AM) technologies comprise a family of manufacturing methods that colloquially are known by the common appellation of “3D Printing.” AM has created a strong linkage between digital and physical manufacturing, thus nourishing by its nature, a wider trend, digitization, and the automation of the manufacturing industry. This chapter presents an overview of the gross elements for a generic AM process. Industrial applications of functional metal. AM components can be found across various sectors including nuclear power, oil & gas, turbine components, wind & tidal energy, fuel cell components, and electromagnetic energy. AM lends increased design freedom for the manufacturing of unique functional geometries. AM processes on account of being a selective consolidation based manufacturing processes offer tremendous flexibility in functional material gradients. Powder bed fusion refers to a class of AM processes. Solid-state AM is a class of processes that use friction and diffusion-based mechanisms to produce mechanical bonding without melting.
