Selective Laser Melting (SLM), also referred to as Laser Powder Bed Fusion (L-PBF), offers significant advantages for the manufacturing of complex, high-quality parts. However, its market share is still small compared to conventional manufacturing technologies. Major drawbacks hindering an industrial ramp-up are low productivity, high part costs and issues with quality and reproducibility. Comprehensive research has been done to overcome these challenges, but little attention has been paid to addressing them by optimizing the laser beam profile. Therefore, the author examines the effect of the laser beam profile on the productivity and process stability through both numerical and experimental investigations. The results show clear advantages an optimized laser beam profile offers.

Selective Laser Sintering Additive Manufacturing Technology is a unique and comprehensive guide to this emerging technology. It covers in detail the equipment, software algorithms and control systems, material preparations and process technology, precision control, simulation analysis, and provides examples of applications of selective laser sintering (SLS). SLS technology is one of the most promising advances in 3D printing due to the high complexity of parts it can form, short manufacturing cycle, low cost, and wide range of materials it is compatible with. Typical examples of SLS technology include SLS manufacturing casting molds, sand molds (core), injection molds with conformal cooling channels, and rapid prototyping of ceramic and plastic functional parts. It is already widely used in aviation, aerospace, medical treatment, machinery, and numerous other industries. Drawing on world-leading research, the authors provide state of the art descriptions of the technologies, tools, and techniques which are helping academics and engineers use SLS ever more effectively and widely. Provides instructions for how to accurately use SLS for forming Analyses the numerical simulation methods for key SLS technologies Addresses the use of SLS for a range of materials, including polymer, ceramic and coated sand powder

Additive manufacturing (AM) is one of the manufacturing processes that warrants the attention of industrialists, researchers, and scientists. AM has the ability to fabricate materials to produce parts with complex shapes without any theoretical restrictions combined with added functionalities. Selective laser melting (SLM), also known as laser-based powder bed processing (LPBF), is one of the main AM process that can be used to fabricate wide variety of materials that are Al-, Ti-, Fe-, Ni-, Co-, W-, Ag-, and Au-based, etc. However, several challenges need to be addressed systematically, such as development of new materials that suit the SLM process conditions so the process capabilities can be fully used to produce new properties in these materials. Other issues in the field are the lack of microstructure–property correlations, premature failure, etc. Accordingly, this Special Issue (book) focuses mainly on the microstructure-correlation in three different alloys: AlSi10Mg, Ti6Al4V, and 304L stainless steel, where six articles are presented. Hence, this Special Issue outlines microstructure–property correlations in the SLM processed materials and provides a value addition to the field of AM.

The manufacture and use of the powders of non-ferrous metals has been taking place for many years in what was previously Soviet Russia, and a huge amount of knowledge and experience has built up in that country over the last forty years or so. Although accounts of the topic have been published in the Russian language, no English language account has existed until now. Six prominent academics and industrialists from the Ukraine and Russia have produced this highly-detailed account which covers the classification, manufacturing methods, treatment and properties of the non-ferrous metals ( aluminium, titanium, magnesium, copper, nickel, cobalt, zinc, cadmium, lead, tin, bismuth, noble metals and earth metals). The result is a formidable reference source for those in all aspects of the metal powder industry. Covers the manufacturing methods, properties and importance of the following metals: aluminium, titanium, magnesium, copper, nickel, cobalt, zinc, cadmium, noble metals, rare earth metals, lead, tin and bismuth Expert Russian team of authors, all very experienced English translation and update of book previously published in Russian
