Abstract
Percentage of infill pattern is one of the important parameter in the 3D printing process when flexibility and cushioning is critical. This study was done by focusing on the structure of insoles foot orthosis produced using 3D printing which is one of the methods in additive manufacturing. Thermoplastic elastomer namely Filaflex and NinjaFlex which was printed by using Flashforge 3d printer was in order to determine the mechanical properties of samples with variations of the percentage infill patterns. In this study, the samples wen through three type of testing, which are tensile test, flexural test and hardness strength for infill pattern of Filaflex was higher value compared to the ninjaflex where 284.6 N for maximum force with 70% of infill of tensile strength of Filaflex and flexural strength for infill pattern 2.28 N for flexural force with 80% of infill show the effective result of Filafex compared to Ninjaflex result. The lowest hardness of Filaflex 7.8 shows the best structure hardness of foot insoles structure.
