“…Apart from the rock mechanical properties [6], especially when transitioning between two distinct layers with different mechanical properties [7], the cutting performance and wear resistance of diamond-reinforced composites depends on the properties of a matrix primarily determined by its elemental composition [8], proportion of diamond grains added [9,10], dimensions of the reinforcement [11], the strength and shape of diamond grits [12], and the additives that have effect on the composite microstructure [13]. In particular, Fe-Cu-Ni-Sn matrices are used for the diamond composites [14,15], due to their high cutting characteristics and tribological properties useful for both soft soil and hard rocks in stationary and quarry conditions alike [16].…”

The paper presents research results on the enhancement of diamond composites designed for tools application for mining industry, hard rocks cutting, able to withstand harsh conditions under heavy dynamical loads. In the present study, both CrB 2 micropowder and VN nanopowder additives were used in proportions up to 5 wt.% and 6 wt.%, respectively, together with the basic matrix composition of 51 wt.% Fe, 32 wt.% Cu, 9 wt.% Ni, and 8 wt.% Sn. Addition of both components, CrB 2 and VN, appeared to be advantageous in proportion of 2 wt.% and 4 wt.%, respectively. This composition exhibited the highest relative density of 0.9968, better than that without additives. Similarly, the highest values of compressive strength R cm and flexural strength R bm were reached for the composite with the same percentage of CrB 2 and VN. Compared to the composite with no addition of CrB 2 and VN, R cm improved by almost 70%, while R bm by 81%. Additionally, the abovementioned additives enhanced the ability of the matrix to prevent the diamond reinforcement from being torn out of the composite, which is very important under harsh working conditions of the cutting tools. The presence of CrB 2 micropowder and VN nanopowder promoted densification of the matrix and adhesion between the diamond grits and the Fe-Cu-Ni-Sn matrix.

“…This method demonstrates considerable economic advantages concerning equipment costs, material costs, and energy consumption, thereby introducing a novel approach for the rapid prototyping of high-melting-point metal materials [18,19]. He et al [20] examined the impact of diamond parameters on diamond tools fabricated using fused deposition modeling (FDM) and sintering technology. The utilization of diamond materials in tool manufacturing offers exceptional mechanical properties, such as high hardness and wear resistance, making it a promising choice for various industrial applications.…”

Fused deposition modeling and sintering (FDMS) is a novel 3D printing technique that combines fused deposition modeling with catalytic debinding and sintering processes to enable the rapid production of metal parts with low energy consumption and costs. Firstly, a 316L/POM composite filament is prepared. Subsequently, test specimens are printed using a fused deposition modeling (FDM) printer, followed by catalytic debinding and sintering processes to create dense metal parts. The process parameters show an influence on the part structure and, subsequently, the properties, and this study examines the microstructural characteristics of the 316L/POM composite filament at each process stage. Using tensile strength as the indicator, an orthogonal experiment is designed to identify suitable combinations of process parameters. Experimental results demonstrate that the FDMS process can manufacture 316L stainless steel parts; moreover, they influence the structure and, consequently, the mechanical behavior, as these are strongly related. By appropriately adjusting the process parameters, this method can be suitable for applications requiring functional parts with less stringent strength requirements.

Additive manufacturing, particularly 3D printing, has revolutionized the manufacturing industry by allowing the production of complex and intricate parts at a lower cost and with greater efficiency. However, 3D-printed parts frequently require post-processing or integration with other machining technologies to achieve the desired surface finish, accuracy, and mechanical properties. Ultra-precision machining (UPM) is a potential machining technology that addresses these challenges by enabling high surface quality, accuracy, and repeatability in 3D-printed components. This study provides an overview of the current state of UPM for 3D printing, including the current UPM and 3D printing stages, and the application of UPM to 3D printing. Following the presentation of current stage perspectives, this study presents a detailed discussion of the benefits of combining UPM with 3D printing and the opportunities for leveraging UPM on 3D printing or supporting each other. In particular, future opportunities focus on cutting tools manufactured via 3D printing for UPM, UPM of 3D-printed components for real-world applications, and post-machining of 3D-printed components. Finally, future prospects for integrating the two advanced manufacturing technologies into potential industries are discussed. This study concludes that UPM is a promising technology for 3D-printed components, exhibiting the potential to improve the functionality and performance of 3D-printed products in various applications. It also discusses how UPM and 3D printing can complement each other.
