For a wide range of utilization, 3D printing is a swiftly developing technology that demands meticulous evaluation of materials, production speed, and resolution. Significant outcomes have been obtained from the application of 3D technology in Cultural Heritage (CH) protection, the valorisation process, communication, and asset incorporation; this is especially true of interdisciplinary initiatives including manufacturing engineering, computer-generated records, and CH accessibility. The primary factors influencing the layout and choosing materials for additive manufacturing are applicability and fabrication technique. A wide range of materials, comprising ceramics and metals, hydro-gels, thermoplastic substances and combinations of these substances, can be used. This study investigates the design and fatigue analysis of a 3D-printed square block made of thermoplastic polyurethane (TPU) under various test conditions, including static structural analysis for compression, fatigue analysis and total deformation within the block layer. The uniform stress distribution was also discussed in detail, as well as the design life and safety factors of the block under fatigue conditions, with its natural frequencies observed in experimental results adjusted the printing parameters for and maintained the process to ensure the best output quality. Post-publication steps included detailed analysis and mechanical testing to verify mechanical properties and dimensional accuracy.

This study investigates the enhancement of aluminum-based composite manufacturing by incorporating Si3N4 reinforcement via the stir casting technique. Aluminum alloy serves as the matrix material, augmented with ceramic reinforcement particles. The alloy is melted at approximately 700°C in a muffle furnace, with ceramic particles gradually introduced and dispersed homogeneously through continuous stirring at 400 rpm for 10 minutes. The uniform distribution of Si3N4 particles underscores the efficacy of the stirring technique. Addition of 7.5% Si3N4 reinforcement results in substantial improvements across mechanical properties: tensile strength increases by 24.76%, hardness by 24.76%, fatigue strength by 26.78%, and wear resistance by 29.50%. These enhancements highlight the effectiveness of Si3N4 reinforcement in augmenting the performance of aluminum composites. The findings hold significant implications for industries requiring lightweight, high-strength materials, such as aerospace, automotive, and manufacturing, suggesting promising avenues for further research and practical applications in advanced engineering materials.

This study explores the advancement of aluminum-based composite manufacturing by leveraging tungsten carbide (WC) reinforcement through the stir casting technique. Aluminum alloy served as the matrix material, enriched with ceramic reinforcement particles. The alloy underwent complete melting in a muffle furnace, maintaining a temperature of about 700°C. Ceramic particles were methodically introduced into the molten alloy, ensuring homogeneous dispersion through continuous stirring at 400 rpm for 10 minutes. The resulting composite exhibited a uniform distribution of WC particles, seamlessly integrated throughout the alloy matrix. Remarkably, the addition of 7% WC reinforcement led to substantial enhancements in mechanical properties: a 22.67% improvement in tensile strength, a remarkable 37.9% increase in hardness, a notable 25.80% enhancement in fatigue strength, and a significant 27.67% improvement in wear resistance. These findings underscore the efficacy of the stir casting technique in optimizing the properties of aluminum-based composites, offering promising avenues for the development of high-performance materials for diverse engineering applications.
