Summary: This study successfully fabricated nondestructive porous copper with ultrahigh porosity by adding 90% spacer content using needlelike carbamide as a space holder. The use of a wire mesh support during the decomposition process was crucial for manufacturing highly porous copper. The obtained porous copper samples exhibited an open-cell structure with a dense skeleton, and showed typical characteristics of elastic-plastic metal foam in compressive tests.

Summary: This study successfully manufactured porous MAX phase Ti3SiC2 using Powder Injection Moulding (PIM) without the need of a space holder, aiming to broaden the application fields of MAX phase. In-depth characterization and control of all process stages were conducted to produce sustainable feedstocks with good properties for injection moulding. The selection of binder with reduced carbon footprint, use of critical solid loading and optimized debinding conditions, as well as adjusted sintering parameters contributed to the successful achievement of porous MAX phase samples.

Summary: This research studied the challenges of fabricating titanium components through low-pressure powder injection moulding (LPIM). It was found that feedstock with high powder loading was not suitable for LPIM, and suitable parameters for solvent debinding were obtained by soaking the samples in n-hexane at 60 degrees C temperature. After sintering, the hardness and density of the sintered part were 490 HV and 4.11 g/cm³, respectively, with coarse alpha plates and alpha/beta colonies observed in the microstructure.

Summary: The feasibility of making porous Al2O3-Ti composites using SPS processing with NaCl particles as space-holders was evaluated in this study. Different strategies were used to achieve samples with appropriate porosity. The vacuum sintering process improved the corrosion resistance and hardness of the composites, and both Al2O3-Ti and Ti samples showed non-toxic characteristics before and after heat treatment.

Summary: This study presents a promising alternative approach in powder injection molding (PIM) process by utilizing irregular-shaped and bimodal size powder in Ti6Al4VHA composite. The irregular-shaped Ti6Al4V-HA exhibits good rheological behavior and low viscosity, producing crack-free parts with high relative density of 95% after sintering, showing excellent osseointegration properties. The findings suggest the suitability of irregular-shaped Ti6Al4V-HA as a useful alternative material for biomedical applications, especially in bone implantation.

Summary: The increase in power density of power electronics depends on reducing the size of passive components. Traditional fabrication techniques for ferrites have limitations in producing cores with advanced geometrical features. Additive manufacturing or powder injection moulding are promising techniques that allow for the shaping of magnetics with unprecedented geometrical features. The study found that cores with a loading rate of 84.7 wt% had the lowest power losses, attributed to better magnetic phase purity.

Summary: The study investigated the influences of powder size, powder content, and mould design on the successful production of micro-scaled structures using 17-4 PH stainless steel feedstock. It was found that 10 μm sized particles ensured complete filling within microtextures for all mould variations. The results suggest that the proposed mould insert preparation technique opens new possibilities for mass production of micro-scaled components using feedstocks without nanoparticles.

Summary: A new method combining the advantages of both reactive synthesis and space holder method was explored through the fabrication of TiAl3-Al porous materials at low titanium content. The composition, structure, and mechanical properties of different titanium content were further studied. Reduction of titanium content and sintering in the air effectively reduced the reaction intensity of titanium and aluminum, resulting in retained pore wall morphology and in-situ generated small pores. Complex changes caused by titanium content not only led to morphological changes and matrix transformation but also significantly affected the mechanical properties.

Summary: An inverse numerical analysis method was used to determine the localized mechanical properties of fused silica, which requires time-consuming numerical calculations and experienced researchers. The study found that mechanical properties have a significant impact on the nanoindentation parameters of fused silica, and adjusting these properties can lead to satisfactory load-displacement curves.

Summary: The mechanical properties of a new low-modulus beta titanium alloy, designed for biomedical applications, were measured and compared after being processed by selective laser melting (SLM) and metal injection moulding (MIM) techniques. Results showed that SLM produced materials with superior strength, low modulus, and high ductility, while MIM produced materials with similar strength/stiffness ratios but lower ductility due to carbon pickup from the binder and slower cooling rates affecting the microstructure.

Summary: This study investigated the effects of specimen layout on the physical, microstructural, and mechanical properties of 17-4PH fabricated using metal-fused deposition modeling. Specimens with a flat layout showed the best appearance, green density, sintered density, and tensile properties, while specimens with a vertical layout exhibited the worst performance. The difference in tensile properties between side and flat layouts was attributed to the larger and more detrimental voids in the side layout, as evidenced by cracking in the fracture surface.

Summary: This study evaluated the damage characteristics of hydroxyapatite (HAp)-coated porous Ti components under cyclic compression in a simulated body fluid (SBF). The results showed that delamination of the HAp coating was the primary failure mechanism in SBF, but could be partially recovered through re-precipitation from SBF.

Summary: Metal extrusion additive manufacturing (Metal MEX) is a simple and cost-effective 3D printing process, which involves the preparation of metal powder and polymer binders as feedstock, layer-by-layer printing or injection to create green parts, and debinding and sintering to produce consolidated metallic parts. The rapid development of Metal MEX calls for a review of current research to understand the process parameters and properties for further studies and applications. This article systematically summarizes the literature on feedstock, printing, debinding, and sintering, and discusses the physical and mechanical properties of Metal MEX parts compared to well-established Metal Injection Moulding (MIM) properties, providing an assessment of the current stage of Metal MEX development.

Summary: Ti-Mo alloys were prepared by metal injection moulding (MIM) and sintering method, and the effects of Mo powder additions on the physical, mechanical and corrosion properties of commercially pure Ti were investigated. The study found that the tensile strength of the alloys increased with increasing Mo content, while the strain to failure varied due to TiCx formation, sintered density, and impurities. The optimum alloy was Ti-7.5Mo, sintered at 1250°C for 2 hours, which exhibited suitable tensile properties, high relative density (>96.5%), and excellent corrosion resistance in an artificial saliva environment, making it an ideal material for biomedical applications.

Summary: In this study, the surface quality, physical, microstructural, tensile, and axial fatigue properties of 316L stainless steel fabricated by materials extrusion additive manufacturing (MEX) and metal injection molding (MIM) were investigated. The results showed that there were no significant differences in microstructure, orientation, and grain size between MEX and MIM parts, except for voids in MEX parts and Si-O inclusions in MIM parts. MEX parts had slightly higher tensile properties due to higher sintered density but lower fatigue resistance compared to MIM parts.
