“…Many effective methods, such as using high quality sintered powder, reducing the oxygen content, and adding reinforcing phases, have been carried out to improve its mechanical properties [ 5 , 6 ]. The strength and density of the sintering specimens were improved with the usage of atomized powder and a dense sintering graphic mold [ 1 , 2 , 3 , 4 , 5 , 6 ]. The content of inclusions was reduced by sintering the powder under a vacuum atmosphere, as the metal particles were susceptible to reaction with oxygen at high temperatures [ 7 ].…”

The selective laser melting of tin bronze (CuSn10) powder was performed with a laser energy density intensity level at 210, 220, and 230 J/mm2. The composition was homogeneous with almost all tin dissolved into the matrix. The grain size of the obtained alpha copper phase was around 5 μm. The best properties were achieved at 220 J/mm2 laser energy density with a density of 8.82 g/cm3, hardness of 78.2 HRB (Rockwell Hardness measured on the B scale), yield strength of 399 MPa, tensile strength of 490 MPa, and an elongation that reached 19%. “Balling effect” appeared and resulted into a decrease of properties when the laser energy density increased to 230 J/mm2.

In the pursuit of achieving zero emissions, exploring the concept of recycling metal waste from industries and workshops (i.e., waste-free) is essential. This is because metal recycling not only helps conserve natural resources but also requires less energy as compared to the production of new products from virgin raw materials. The use of metal scrap in rapid tooling (RT) for injection molding is an interesting and viable approach. Recycling methods enable the recovery of valuable metal powders from various sources, such as electronic, industrial, and automobile scrap. Mechanical alloying is a potential opportunity for sustainable powder production as it has the capability to convert various starting materials with different initial sizes into powder particles through the ball milling process. Nevertheless, parameter factors, such as the type of ball milling, ball-to-powder ratio (BPR), rotation speed, grinding period, size and shape of the milling media, and process control agent (PCA), can influence the quality and characteristics of the metal powders produced. Despite potential drawbacks and environmental impacts, this process can still be a valuable method for recycling metals into powders. Further research is required to optimize the process. Furthermore, ball milling has been widely used in various industries, including recycling and metal mold production, to improve product properties in an environmentally friendly way. This review found that ball milling is the best tool for reducing the particle size of recycled metal chips and creating new metal powders to enhance mechanical properties and novelty for mold additive manufacturing (MAM) applications. Therefore, it is necessary to conduct further research on various parameters associated with ball milling to optimize the process of converting recycled copper chips into powder. This research will assist in attaining the highest level of efficiency and effectiveness in particle size reduction and powder quality. Lastly, this review also presents potential avenues for future research by exploring the application of RT in the ball milling technique.

The application of semi-solid metal forming technology to the production of high-quality copper alloy parts has attracted more and more attention. Accordingly, as the key and foundation of semi-solid metal forming technology, it is particularly important to stably and efficiently prepare copper alloy semi-solid slurry with high quality. The purpose of this study was to innovatively optimize the process parameters by combining multiple optimization algorithms to stabilize the preparation of high-quality CuSn10P1 semi-solid slurry. And the self-developed Fully Enclosed Melt-Constrained Cooling Inclined Plate (FEMCIP) device was taken as the experimental equipment. Based on the optimization method of neural network genetic algorithm, the parameters of the preparation process of CuSn10P1 semi-solid slurry were optimized by combining orthogonal experimental design, grey correlation analysis method and Latin hypercube sampling, and using the finite element analysis software ProCAST and data analysis software MATLAB with the average shape factor as the evaluation index. By comparing with the slurry before optimization, numerical simulation results and experimental verification results, it was found that the semisolid slurry prepared by the crucible with preheating temperature of 990°C, cooling water flow rate of 680.517 L/h, cooling channel angle of 45°, inclined plate length of 300 mm and quasi-isothermal time of 42.715 s had the best quality. In this research, the semi-solid slurry of CuSn10P1 alloy with uniform microstructure and high roundness of solid particles was prepared by using this optimization method, which provided a new optimization strategy for the preparation of semi-solid metal slurry by using inclined plate type equipment.
