A person may develop ear problems because of an accident or a birth condition. Such flaws damage a person’s appearance and feelings of confidence, forcing them to shun social situations. To improve their appearance, patients may choose to have a prosthetic ear implanted. This project entails a 3D scanning model of an artificial ear as well as analyzing various material properties such as thermoplastic polyurethane (TPU), thermoplastic elastomer (TPE), and nylon (PA6). These are the alternatives chosen to replace the current use of silicone material to produce the prosthetic ear. This project uses a 3D scanner to scan an artificial ear model that was made from silicone material. The aim of analyzing various materials on the artificial ear model is to decide the best material that can be used for the patient’s head. The material is analyzed using finite element analysis on SOLIDWORKS software. The material that is suitable for the patient to be used as a prosthetic ear is Nylon 6 due to its low deformation value and lowest stress value. This prosthetic ear allows the patient to participate more fully in their social and family lives, making them happier and more at ease. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
