“…The data suggest PA11 exhibits a very high degree of toughness and ductility, particularly at low temperatures, but at slightly decreased modulus. Lin et al [ 224 ] synthesized PA 12 coated composite powders with varying amounts of Al powder. The bending strength and modulus of sintered components increase significantly as the percentage of aluminum powder increases, but the impact strength gradually decreases.…”

“…However, the mechanism leading to aging is still unclear. [ 224 ] In 2015, Wudy et al [ 227 ] explored the degradation behavior of PA12 powder in the SLM process in various environmental conditions, including air, nitrogen, and vacuum. They found that using a vacuum or nitrogen environment can effectively reduce the impact of high temperature on material aging.…”

As a 0‐dimensional moulding material, powder particles can realise the construction of most engineering parts and can further improve the precision moulding and high‐performance manufacturing capabilities of additive manufacturing (AM). Therefore, the powder‐based additive manufacturing methods provide an outstanding practical value and development for modern manufacturing world. However, powder materials that are utilised in additive manufacturing continue to face challenges such as a lack of accessible categories, temperature restrictions, and poor performance of moulded components. Therefore, researching for new additive manufacturing materials and procedures has become one of the important and influential ways to accelerate the progress of additive manufacturing technology and also to expand its application fields. For this purpose, it is invaluable to understand and update on the current state‐of‐the‐art of powder‐based additive manufacturing technologies. Hence, this work first reviews the research background of powder‐based 3D printing in details while systematically expounding on the technologies and equipment, material types, influencing factors, existing problems and development trends of powder‐based 3D printing. In addition, the basic principles of powder‐based 3D printing were also revealed, and the formation and optimization of metal, polymer, and ceramic powders in powder‐based 3D printing equipment were explored. Throughout the last decade, powder‐based AM has gradually emerged in the fields of biomedical and aerospace, such as the construction of tissue scaffolds and the construction of aero‐engine parts, respectively. However, powder materials may have insufficient comprehensive performance due some limitations, as the control of mechanical characteristics and dimensional accuracy of powder moulded parts are still challenging during manufacturing processes. Therefore, exploring the mechanism/s of additive manufacturing of powder‐based materials, improving the mechanical properties of powder‐based AM products, and the possible directions for improving the usability of powder materials are the main focus of this paper.This article is protected by copyright.

“…Compared with other purification approaches, such as slag engineering, flow control, and so on, melt filtration is easy to handle, widely adaptable, and less influences the metallurgical process. In the past few decades, the preparation [5,6], filtration efficiency [7,8], functionalization [9,10], and property characterization [11,12] of the open-cell ceramic foams have been intensively studied.…”

To widen the understanding of tensile failure of reticulated ceramic foams and expand the available mechanical method, a cylindrical splitting test is developed in the present study based on alumina open-cell foams of three different pore densities. The biaxial method is validated by characterization of mechanical parameters, and the in-situ fracture process is validated by a digital image correlation, followed by a formula correction for effective tensile strength with consideration of discrete crack paths. For experimental setup curved loading platens, compliant pad and intermediate quasi-static loading rate are proposed for guaranteeing tensile failure under a radial compressive load. Tensile strength, fracture energy, and brittleness increase with the foam pore density, and the fracture behavior is a balanced result of materials and foam structural support strength. An analytical model of splitting tensile strength with structural parameters is derived, which implies its dependence on cell size and critical stress intensity factor of strut materials.

“…Despite the promising manufacturing approach, the 3D printing and replica technique was mainly used for the production of ceramic‐based supports, such as silicon carbide, 33,34 alumina 35 and zirconium diboride, 36 while most of the aforementioned powder‐based methods are only relevant for metallic powders.…”
