“…As for SLS, SLM, this kind of particles will lead uneven spread powder and cracks in every layer in laser sintering. Large spherical particles have better rollability, but they will affect the print accuracy of parts [59]. The powder particle size of the forming different materials depends on the material itself and the type of printer type.…”

Additive manufacturing is a rapid manufacturing based on discrete accumulation to achieve prototypes or parts of products. Inorganic non-metallic materials, as one of the three major materials, have incomparable application prospect in medical, aerospace, automotive, construction, arts and crafts, as well as many other fields. In order to rapidly create devices with arbitrarily complex shapes, additive manufacturing of inorganic non-metallic materials is becoming a hot spot of current research. In view of the technical types, materials and other aspects, this article introduced research status and development of additive manufacturing in inorganic non-metallic materials at home and abroad. Several common inorganic non-metallic materials are compared and analyzed, such as Al2O3, Si3N4 SiO2, ZrO2, etc. The forming characteristics and the problems of several popular ceramic materials and sand–casting materials are illustrated with emphases. The key problems existed in additive manufacturing forming process of inorganic non-metallic material are pointed out and urgent to be solved at present. Furthermore, the impacts of the material handling process, three dimensional printing (3DP), Selective Laser Sintering(SLS), Selective Laser Melting (SLM) three-dimensional forming processes and post treatment process on the quality and performance of the forming parts are analyzed. Finally, the prospects in SLS of the gem material are put forward.

“…PM is a field of technology covering the manufacturing methods of powders of materials and metallic materials or their mixtures with non-metallic powders and the manufacturing of semiproducts and products from such powders without having to melt the main component [1][2][3][4][5][6][7]. At present, in about 80% the parts fabricated by powder metallurgy methods are employed in the automotive industry, mainly for economic reasons.…”

This chapter is an introduction to the book on powder metallurgy (PM). It presents the basis of the selection of powder metallurgy technologies for manufacturing of products, including such applied in medicine and dentistry, and the state of the art concerning the general characteristic of powder metallurgy. The materials and products manufactured with the classical powder metallurgy methods are generally described. The last section presents the general contents of the book based on the above general information.

“…Advanced sintered tool materials, due to the character of their work and complex wear mechanisms to which cutting tool edges are subjected, should satisfy numerous requirements including, in particular, high hardness, high impact strength, resistance to complex wear (adhesive, diffusive, abrasive and thermal wear) and to high temperatures, high compressive strength, stretching, flexing and bending, high fatigue and thermal strength, good conductivity and thermal capacity, cutting edge stability and good ductility [1][2][3][4][5][6][7][8]. A tool material with universal applications should merge the mentioned properties as far as possible and especially the highest wear resistance and hardness with high strength and good ductility accompanied by chemical inertness towards the workpiece.…”

This chapter presents a general characteristic of sintered tool materials, in particular sintered sialons, nitride ceramics, injection-moulded ceramic-metallic tool materials and cemented carbides and a general characteristic of their surface treatment technology and especially chemical vapour deposition (CVD) and physical vapour deposition (PVD) techniques. The results of our investigations in technology foresight methods concerning the development prospects of surface engineering of sintered tool materials are presented. In the next subsection, we discuss the outcomes of multifaceted research carried out with advanced materials engineering methods, including high-resolution transmission electron microscopy, into the structure and properties of multicomponent, graded and multilayer coatings on the investigated tool materials, including the newly developed injection moulded ceramic-metallic tool materials. Special attention was drawn to a one-dimensional structure of the studied PVD and CVD coatings and its impact on the properties of coatings.Keywords: sintered tool materials, foresight, surface engineering, PVD, CVD, coatings, nanostructure General characteristic of sintered tool materialsPowder metallurgy has found widespread applications in the manufacture of sintered tool materials.

Despite the intensive development of materials engineering, a tool material has still not been produced which fulfil such requirements due to a fundamental contradiction between such properties as hardness and ductility.As mentioned in the Introduction section, in general-in the group of sintered tool materialsone can distinguish super hard sintered materials, mixe...
