Making method and application of 3D printing arch supports

Abstract

The invention discloses a making method of 3D printing arch supports. The making method comprises the following steps: examining conditions of a patient; conducting 3D scanning on foot bottoms of thepatient, so that 3D scanning data of the foot bottoms is obtained; scanning the bottom surfaces of insoles which are used by the patient in daily life via a 3D scanner, so that 3D scanning data of thebottom surfaces of the insoles is obtained; as for establishment of a 3D insole model digital document, and introducing the 3D scanning data of the foot bottoms and the 3D scanning data of the bottomsurfaces of the insoles via 3D Max and netfabb software, so that the 3D insole model digital document is generated; firstly, forming the full-length insoles, then changing the full-length insoles into arch supports, and finally, correcting the arch supports in accordance with a requirement of foot orthopedics, so as to obtain final arch support data; conducting printing via a 3D printing machinein accordance with the arch support data, so that half-finished arch support products are obtained; and conducting fine processing on the half-finished arch support products, so that the finished archsupport insoles are obtained. The 3D printing arch supports are comfortable to wear; adopted materials are reduced and pertinence is enhanced; the arch supports are small in occupied area when placedon the foot bottoms; and the arch supports are more suitable for the patient to wear.

Description

technical field [0001] The invention relates to the technical field of arch pad processing, in particular to a manufacturing method and application of a 3D printed arch pad. Background technique [0002] As the fulcrum of the human body when standing and walking, the foot is affected by the interaction of internal and external forces. The good biomechanical structure of the foot can provide the body with balance, control and coordination. If there is a dysfunction in the foot, it will lead to poor symmetry of the skeletal system above the foot and deviation from the neutral position, which will lead to joint problems in the knees, hips, pelvis, and spine, and affect human health. [0003] Foot pathological posture can be divided into: flat foot, equinus, pronated foot, supinated foot, etc. Excessive pronation of the foot will increase the exercise load of the tibialis anterior muscle, which is prone to overuse injury. Excessive supination of the foot causes a decrease in ...
