DEVELOPMENT OF ACTIVE MANUFACTURING INSOLES FOR THE PREVENTION OF FOOT ULCERS IN INDIVIDUALS WITH DIABETES

Abstract

Diabetes mellitus is characterized by insulin resistance and/or insufficient production of this hormone, and one of its complications is peripheral neuropathy, which alters plantar sensitivity and can cause foot ulcers due to high pressure or traumatic agents. Custom insoles are a therapeutic approach often recommended for these individuals, as they contribute to the redistribution of plantar pressures and the reduction of shear forces, acting to prevent these injuries and assisting in treatment. This study evaluated the production of custom insoles by rapid prototyping for the prevention of plantar ulcers in diabetic individuals, with the aim of establishing a technically viable protocol. This method was divided into stages, which involved scanning, software modeling, 3D printing, and post-processing, which includes cutting the coating materials and attaching them to the insole. The manufacture of insoles by additive manufacturing has proven to be efficient and sustainable, as it reduces costs, optimizes time and materials, and generates less waste. Thus, this method enables accurate and customizable production, allowing for better adaptation to the specificities of each individual.
