“…It was found that in the SLM forming process, under good process parameters, a good metallurgical combination can occur between 10% SiC particles and Al Si10Mg to generate a new phase Al4SiC4, with a refined grain size and improved composite properties. Further research shows that the strength of 10% SiC reinforced AlSi10Mg composite specimens formed with SLM is greatly improved compared with the conventional casting process; the materials can achieve high density and strength under the appropriate combination of process parameters [ 97 , 98 ].…”

SLM (Selective Laser Melting) is a unique additive manufacturing technology which plays an irreplaceable role in the modern industrial revolution. 3D printers can directly process metal powder quickly to obtain the necessary parts faster. Shortly, it will be possible to manufacture products at unparalleled speeds. Advanced manufacturing technology is used to produce durable and efficient parts with different metals that have good metal structure performance and excellent metal thermal performance, to lead the way for laser powder printing technology. Traditional creative ways are usually limited by time, and cannot respond to customers’ needs fast enough; for some parts with high precision and complexity, conventional manufacturing methods are inadequate. Contrary to this, SLM technology offers some advantages, such as requiring no molds this decreases production time and helps to reduce costs. In addition, SLM technology has strong comprehensive functions, which can reduce assembly time and improve material utilization. Parts with complex structures, such as cavities and three-dimensional grids, can be made without restricting the shape of products. Products or parts can be printed quickly without the use of expensive production equipment. The product quality is better, and the mechanical load performance is comparable to traditional production technologies (such as forging). This paper introduces in detail the process parameters that affect SLM technology and how they affect SLM, commonly used metal materials and non-metallic materials, and summarizes the current research. Finally, the problems faced by SLM are prospected.

“…One of the main advantages of coarse grain SiC ceramic is high electrical and thermal conductivity and improved oxidation resistance [21,22,23,24,25]. Despite intensive improvement in traditional technologies and advanced approaches as additive manufacturing [26,27], self-propagating synthesis, field-assisted sintering, selective laser sintering [28], energy and material-consuming steps for the production of fine/coarse SiC powders and their consolidation remain a challenge. It is especially crucial for complex bulk architectures and demanding applications [22,29].…”

Mechanical properties of composites produced from the SiC-rich furnace slag using traditional stone and ceramic machining technologies were studied. A non-uniform mixture of coarse monocrystalline SiC grains soaked with Si-metal and glassy oxide phases represented the microstructure of dense monolithic SiC-rich samples. The fracture mechanism of coarse-grained SiC-rich composites was susceptible to the grain size/sample geometry and machining conditions yielding flexural strength in the range of 50-106 MPa and high compression strength of 750 MPa. Despite inhomogeneous macro and microstructure, mechanical and thermal properties are comparable to the traditionally produced siliconized SiSiC ceramics. It opens up the opportunity for the circular economy and value-added recycling of the Si/FeSi industries’ wastes.
