The additive manufacturing (AM) process is used for joining materials to make objects from 3D model data, usually layer upon layer, contrary to subtractive manufacturing methods. This technology plays a significant role in fabricating orthopedic implants, especially parts of hip implants (HI), such as femoral head, stem, neck, polyethylene linear, acetabular shell, and so on, using biomaterials. These biodegradable resources are those that can be utilized as tissue substitutes since they are accepted by live tissues. Here, the study is to examine the most preferable AM process and biomaterial used for making HI, including its manufacturing methods, compositions, types, advantages, and defects and cross-examining the limitations to bring some new technology in the future. Then we elaborate on the outlook of the most preferable material, followed by evaluating its biocompatibility, detailed application, and structural defects occurring while using it as an HI. Subsequently, the physical characteristics and design constraints are also reviewed in the paper. We assess the current stage of the topology optimization technique (TO) with respect to the characteristics of newly designed implants. The review concludes with future perspectives and directions for research.

Experimental fabrication of functionally graded Aluminum Silicon-carbon nanotubes (AlSi-MWCNT) reinforcement is significantly less, despite substantial theoretical interest. Many studies focused on axially layered functionally graded material because of ease of fabrication. Full advantage of AlSi-MWCNT functionally graded material only is taken when designed to the various shapes. In this research work, functionally graded cylinders were produced with 2wt% MWCNT at the outer surface to provide a complex and wear-resistant surface. The interior surface is soft with AlSi to provide elasticity. FGM1 sample indicates 112% and 11% increase in maximum tensile strength compared to AlSi and AlSi-MWCNT1wt%. FGM1 sample shows a 37% increase in elongation percentage compared to the AlSi-MWCNT1wt% composite. Test samples showing the typical nature of barrelling. FGM1 sample exhibits compressive strength of 237MPa, exceeding by 245% that of AlSi and by 3.5% that of AlSi-MWCNT1wt%. Three samples consider for each test. Hardness value ranges from 65HV at the core to 115HV at the outer surface. Hardness value Exceeds 56% in the outer layer compared to an inner region of FGM2.There is a proper bond between the layers, and the same demonstrate with properties of tensile, compressive, and hardness. OM with porosity, SEM with EDX evaluates to predict structural gradation in FGM cylinder.

“…In this study, functionally graded Ti-6Al-4V mesh structures are studied under identical bulk stress conditions to determine their fatigue behavior. Fatigue cracks begin in the weakest constituent, then spread until they fail structurally [13]. Microstructural anisotropy was investigated on fatigue crack growth behavior of laser powder bed fusion-fabricated functionally graded Inconel 718.…”

This paper presented an experimental and numerical study of functionally graded materials made by the permanent casting method and in three models with different mixing ratios between aluminum and zinc alloys (FGM1, FGM2, and FGM3) as in figure 1. In the permanent casting process, three models of the functionally graded material were produced and mechanical tests were conducted on them such as tensile and hardness tests, and the behavior of tensile strength, yield strength, elastic modulus, and fatigue was analyzed on them. The fatigue test was conducted at six levels of load and at room temperature. Simulations were carried out for the three models and a simulated fatigue test for the functionally graded material into the Ansys program. The results of the fatigue test showed an apparent effect of the different mixing ratios of the functional-grade material. As well as the numerical results were, close to the experimental results. There was an improvement in the fatigue life compared to FGM3, by 23% to FGM2. In addition, the fatigue life of the FGM3 of 11% higher than from the FGM1 model. In addition to that, which is important, the improvement in the fatigue life characteristics of the third type was 36% compared to the alloys from which the functionally graded materials were made.
