| Summary: | Foot shapes are divided into three types, namely flat feet, normal, and high arch. The human foot, especially the heel, supports the weight of the human body when doing activities. Therefore, the insole must be designed to be comfortable and can support the weight of the human body. A good insole must be able to distribute even pressure on the foot so that it can reduce foot pain. Therefore, the insole must be made of an elastic material. The use of additive manufacturing methods for making insoles is expected to reduce inefficiencies in terms of time, insole weight, and costs.
The research step begins with the design process. This process includes foot scanning, foot modeling, foot model validation, insole modeling, printing, and insole model validation. In addition to the design process, this research was also conducted to determine the most elastic material from parameter of infill pattern, the percentage of infill density, and the filament material to determine its elastic modulus. This is done because the more elastic a material is, the more it will be able to absorb the force distribution that is on the foot so that the insole can be used comfortably.
The result of this bachelor thesis is a custom insole made using additive manufacturing methods along with a documented procedure of its design and manufacturing process. Making this insole less than 1 day, weighs of 220 grams, and inexpensive cost to make. The results of tensile testing, it can be concluded that the most elastic material is TPU 85 with an infill pattern is grid and the percentage of infill density is 10%. This research successfully proven that the additive manufacturing method is more effective and cheaper than the conventional method. For further research, compression testing can be carried out and using other materials to improve the insole design.
