“…Other authors also explore the possibility of the additive-manufacturing-depositioninduced microstructure directly affecting the machining process. For the particular case of the Inconel 718 and its microstructure, which is composed of columnar dendrites, not only the relation between cutting and dendritic directionality was studied, concluding that the machining process and its results are different with the different dendrites' direction [39] but also trying to improve the machining stability by performing different deposition strategies to change this directionality and consequently the relation between dendrites and cutting tool [40].…”

Wire and arc additive manufacturing (WAAM) is a metal deposition technique with a fast rate and the possibility of a high volume of deposition. Because of its fast deposition and high heat input, the manufactured products have poor surface quality. This paper presents a study on the machining of Inconel 718 wall-shaped additive manufacturing (AM) products, a necessary step for the improvement of surface quality. Considering the possibility that the characteristics of the milling processes of AM products might differ from those of traditionally manufactured parts, in this research, two types of Inconel 718 were studied and compared: one was manufactured using WAAM, and the other was an Inconel 718 rolled bar (Aerospace Material Specifications 5662). Using the testing procedure, a conventional two-flute cutting tool was used to assess their machinability. For this process, multiple passes were performed at three different heights of the samples. Considering the peculiarities of the AM products, such as their uneven surfaces, dendritic microstructures, and anisotropy, the results were analyzed. After the machining operation, the effects on the products were also studied by analyzing their surface quality. This study found a higher stability in the cutting process for the AMS 5662 samples relative to the WAAM parts with less variability in the cutting forces overall, resulting in better surface quality.

“…Hybrid methods, combining rapid prototyping with powder metallurgy, have also emerged, allowing the creation of intricate lattice patterns previously unattainable with conventional techniques [14]. Nevertheless, Perez's exploration of stiffening near-net-shape functional parts through crystallographic texture control and laser beam shaping provides a future path to use AM with improved mechanical properties [15][16][17]. For instance, their study found that non-Gaussian beam profiles significantly influence the mechanical properties of IN718 during laser powder bed fusion (LPBF) [17].…”

“…The addition of tantalum significantly improves the strength, ductility, and antibacterial properties of the alloy, making it promising for medical implants. As Perez's contributions provide a comprehensive pathway for using SLM and LPBF to create advanced materials with tailored properties, improve material performance, and expand their application in critical fields, Ti-6Al-4V-Ta has a chance to be the future investigated material after IN718 [15][16][17]. Nevertheless, improving the post-processing and finishing of samples made of Ti-6Al-4V-Ta, as in the study of Singh et al [18], is an advantage for future investigations.…”

This study investigates the effect of a tantalum addition and lattice structure design on the mechanical and antibacterial properties of Ti-6Al-4V alloys. TPMS lattice structures, such as Diamond, Gyroid, and Primitive, were generated by MSLattice 1.0 software and manufactured using laser powder bed fusion (LPBF). The results indicate that Gyroid and Primitive structures at a 40% density exhibit superior ultimate compressive strength, which closely emulates bone’s biomechanical properties. To be precise, adding 8% tantalum (Ta) significantly increases the material’s elastic modulus and energy absorption, enhancing the material’s suitability for dynamic load-bearing implants. Nevertheless, the Ta treatment reduces bacterial biofilm formation, especially on Gyroid surfaces, suggesting its potential for infection management. Overall, all findings provide critical insights into the development of advanced implant materials, contributing to the fields of additive manufacturing, materials science, and biomedical engineering and paving the way for improved patient outcomes in orthopedic applications.

Aiming at the problems of the complex shape, difficult three-dimensional (3D) digital modeling and high manufacturing quality requirements of gas turbine blades (GTB), a method of fitting the blade profile line based on a cubic uniform B-spline interpolation function was proposed. Firstly, surface modeling technology was used to complete the fitting of the blade profile of the GTB, and the 3D model of the GTB was synthesized. Secondly, the processing parameters of the additive manufacturing were set, and the GTB model was printed by fused deposition technology. Then, the rapid investment casting was completed with the printed model as a wax model to obtain the GTB casting. Finally, the blade casting was post-processed and measured, and it was found to meet the requirements of machining accuracy and surface quality.
