Additive manufacturing of industrially-relevant high-performance parts and products is today a reality, especially for metal additive technologies. The design complexity that now possible makes it particularly useful to improve product performance in variety applications. Metal well matured being used production end-use mission-critical parts. next level this development includes the use intentionally designed porous metals - architected cellular or lattice structures. Cellular structures can be tailored specific mechanical other characteristics have numerous advantages due their large surface area, low mass, regular repeated structure open interconnected pore spaces. This considered medical implants lightweight automotive aerospace components, which are main industry drivers at present. Architected behave similar cell foams, found many industrial applications date, such as sandwich panels impact absorption, radiators thermal management, filters catalyst materials, sound insulation, amongst others. advantage additively manufactured precise control micro-architecture becomes possible. huge potential these materials by currently limited concerns over structural integrity. valid concern, when considering process, only recent maturation Many errors occur, so far resulted widely disparate set results literature types structures, with poor fatigue properties often found. These improved years, matching improvement processes. As causes effects on better understood, underlying issues removed mitigated. highly option disruptive new products. review paper discusses progress date manufacturing, metal-based, providing insights glimpse future fatigue-tolerant materials.

Additive manufacturing (AM) processes can produce three-dimensional (3D) near-net-shape parts based on computer-aided design (CAD) models. Compared to traditional processes, AM generate with intricate geometries, operational flexibility and reduced time, thus saving time money. On the other hand, face complex issues, including poor surface finish, unwanted microstructure phases, defects, wear tracks, corrosion resistance fatigue life. These problems prevent from real-time applications. Post-processing techniques, laser shock peening, polishing, conventional machining methods thermal are usually applied resolve these issues. have proved their capability enhance characteristics physical mechanical properties. In this study, various post-processing techniques implementations been compiled. The effect of additively manufactured has discussed. It was found that peening (LSP) cause severe strain rate generation, especially in thinner components. LSP control regularities local grain refinement, elevating hardness value. Laser polishing (LP) reduce roughness up 95% increase hardness, collectively, compared as-built parts. Conventional quality; however, influence not yet. Thermal eliminate porosity 99.99%, resistance, finally, properties’ elevation. For future perspectives, prescribe a particular technique for specific standardization is necessary. This study provides detailed overview properties AM-ed A method be chosen one’s requirements.

Graded lattice structures have been paid wide attention in the engineering and biological fields due to their excellent energy absorption capacity variable porosity characteristics. Based on size-graded structure, laser powder bed fusion is utilized manufacture corresponding Ti-6Al-4 V samples. Then, quasi-static compression experiment conducted a predictive model for its mechanical properties established accordingly. Also, dynamic fatigue behavior studied, influence of sandblasting gradient direction response evaluated. The results show that exhibited vertical graded (VG) structure. Compared uniform elastic modulus are increased by 17.53% 59.43%, respectively. radial (RG) structure similar with minor changes capacity. However, performance RG better than VG With appropriate pores, this can simulate changing physical chemical natural bone. Therefore, it has great potentiality application bone implants.
