Abstract

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.
