Fused deposition modeling has provided a cheap and effective method for the rapid production of prototypes and functional products in many spheres of life. In this study, three-dimensional (3D) printing techniques to produce and optimize a hip protector that will assure clinical efficacy are presented. The I-Optimal design was used to optimize the hip protector's significant parameters (infill density, shell thickness, and material shore hardness) to obtain maximum femoral neck force attenuation of the 3D-printed hip protector. A drop impact tower device simulates the impact force at the hip's parasagittal plane during a fall. The results show that the infill density has the most significant influence on attenuation properties, followed by the infill density combined with the material shore hardness. By maximizing all the parameters, it is demonstrated that using an additive manufacturing technique to print hip protectors could be an effective strategy in curbing hip fractures.

使用响应面方法优化熔融沉积建模生产的三维打印髋部保护器的冲击衰减能力

熔融沉积建模为生活许多领域的原型和功能产品的快速生产提供了一种廉价而有效的方法。在这项研究中,介绍了用于生产和优化髋部保护器的三维 (3D) 打印技术,以确保临床疗效。I-Optimal设计用于优化髋部保护器的重要参数(填充密度、外壳厚度和材料肖氏硬度),以获得3D打印髋部保护器的最大股骨颈力衰减。跌落冲击塔装置模拟跌倒过程中髋部旁矢状面的冲击力。结果表明,填充密度对衰减性能的影响最显着,其次是填充密度与材料肖氏硬度的结合。通过最大化所有参数,证明使用增材制造技术打印髋部保护器可能是遏制髋部骨折的有效策略。
