초록

Foot correction pads should distribute pressure on the foot to relieve pain, requiring suitable materials or structures. This study involved creating 3D models of eight types of foot correction pads based on wool felt products and manufacturing them using TPU through FFF 3D printing. The process included analyzing wool felt pads and manufacturing 3D-printed TPU pads, evaluating their size, printing time, and various design features. The study compared the weight and compressive properties of TPU metatarsal pads with wool pads. The weight analysis revealed that TPU pads were approximately 1.2 times heavier than wool pads due to their higher density and durability. Despite the added weight, TPU pads offered improved durability and better support characteristics. Compressive tests showed that TPU pads had a higher initial compressive modulus compared to wool pads, indicating better support when attached to the foot. Additionally, TPU pads exhibited superior compressive strength and resilience. Thus, 3D-printed TPU foot correction pads demonstrated better performance than wool pads, with higher initial compressive modulus and resilience, offering superior shock absorption and support. They are expected to have a longer lifespan than wool pads, making them a promising material for foot support applications.
