Abstract
3D printed thermoplastic polyurethanes of different shore hardness were used to make hip protectors for the
prevention of osteoporotic hip fracture, which was then tested. The result was used to develop a support vector
regression model to estimate the effect of the protector shore hardness, shell thickness, and infill density on the
impact attenuation capacity at different energy levels. The results from the model show that the impact attenuation
ability of a hip protector is significantly dependent on the infill density of the hip protector and its shore hardness.
Excellent agreement was found between the model results and test results.
