Study of 3D Printing Layered Fiber Fabric Filaments as an Alternative to Polypropylene Materials in Ankle Foot Orthosis for Children with Cerebral Palsy

Children with CP in the moderate category need to use AFO be able walk. products PP materials used by children have drawbacks because design needs of are different. The application additive manufacture adding a layer fiber fabric expected replace materials. basic for making PLA, ABS, PETG and PC filaments carbon texalium types. Tests carried out through tensile impact tests obtain tension values. treatment factors process specimen lamination, type filament, thickness. This study uses factorial model, determine significance value each factor using ANOVA. results show polycarbonate filament layered 301.064 MPa, an 40.68 J/m.
