“…Hence, to improve the properties of PLA printed by the FFF, researchers recommend preparing PLA composites with suitable additives 10 . A number of studies have been conducted on the development of chemical, physical, and mechanical properties of PLA composite parts with filler materials such as aluminum (Al), bronze, copper (Cu), minerals, and natural fibers, printed using FFF technology 11 . In one of these researches, Kottasamy et al 12 examined the effect of different infill patterns on mechanical properties of PLA/Cu printed samples with varying Cu compositions (25 and 80 wt%).…”

Polylactic acid (PLA) is the most widely used material in the fused filament fabrication (FFF) technique, which is a biocompatible thermoplastic. However, PLA's usefulness is limited by its narrow processing window and relatively low mechanical properties. Therefore, PLA composites have been developed to enhance its properties for FFF printing. A key challenge in producing composite parts via this method is to find the correlation between the mechanical properties of the parts and the process parameters. This knowledge is essential for optimizing the printing process to achieve the desired mechanical properties for composite parts industries such as aerospace, automotive, and medical, where high‐performance composite materials are crucial. The ability to control and predict the mechanical properties of FFF‐printed composite parts is critical for their successful integration into these industries. In this study, the effect of nozzle temperature (NT), printing speed (PS), and nominal porosity (POR) on the impact strength and specific impact strength of PLA/iron composites was examined using FFF. Response surface methodology (RSM) was used to optimize the experimental design. The results revealed that POR had the most significant effect on the impact resistance data, while NT had the least effect. Reducing the POR led to improved impact resistance in the samples. Multi‐objective optimization results showed that the lowest NT (190°C), the lowest POR (30%), and a PS of 50 mm/s were the optimal conditions for multiple objectives. RSM was also utilized to develop mathematical models of impact properties, focusing on varying NT, POR, and PS, which can be used to predict desired impact properties.Highlights Nominal porosity has the most influence on the impact strength of PLA/iron composites. Optimum values were temperature of 190°C, nominal porosity of 30%, and speed of 50 mm/s. RSM was effective in enhancing the mechanical properties of composite materials. RSM models provide a predictive tool for future FFF‐printed composite parts. Maximum impact strength of 4.44 kJ/m2 was achieved.

Additive manufacturing (AM) also known as 3D printing (3DP) has become a popular technology with a wide range of applications, from which vat photopolymerization is a technique for producing nanocomposites with controlled mechanical, thermal, and electrical properties. This technology uses a UV light laser to cure a liquid resin into a solid object, layer by layer, allowing complex three-dimensional (3D) objects with intricate details of manufacturing and excellent finishing. Nanocomposites produced by vat photopolymerization have been used in aerospace, automotive, and medical industries, due to their superior mechanical strength and dimensional accuracy. In this article, we will discuss the advantages and other aspects of nanocomposites made with vat photopolymerization, exploring potential applications, and discuss the research by different areas, such as their AM technologies and materials properties. Graphical abstract This review deals with nanocomposites made by additive manufacturing (3D printing), presenting a systematic on vat photopolymerization technology, including the technologies, materials, and properties.

Advancement in medicine and technology has resulted into prevention of countless deaths and increased life span. However, it is important to note that, the modern lifestyle has altered the food habits, witnessed increased life-style stresses and road accidents leading to several health complications and one of the primary victims is the bone health. More often than ever, healthcare professionals encounter cases of massive bone fracture, bone loss and generation of critical sized bone defects. Surgical interventions, through the use of bone grafting techniques are necessary in such cases. Natural bone grafts (allografts, autografts and xenografts) however, have major drawbacks in terms of delayed rehabilitation, lack of appropriate donors, infection and morbidity that shifted the focus of several investigators to the direction of synthetic bone grafts. By employing biomaterials that are based on bone tissue engineering, synthetic bone grafts provide a more biologically acceptable approach to establishing the phases of bone healing. The current review article provides the critical insights on several biomaterials that could yield to revolutionary improvements in orthopaedic medical fields. The introduction section of this article focuses on the statistical information on the requirements of various bone scaffolds globally and its impact on economy. In the later section, anatomy of the human bone, defects and diseases pertaining to human bone, and limitations of natural bone scaffolds and synthetic bone scaffolds were detailed. Biopolymers, bioceramics, and biometals-based biomaterials were discussed in further depth in the sections that followed. The article then concludes with a summary addressing the current trends and the future prospects of potential bone transplants.
