These days, numerous decisions and efforts are contributing to cerebral palsy (CP) cases. Patient with spastic or dyskinetic CP has to survive independently, where most of the time is spent in a wheelchair. An extension headrest must be applied to maximize independence and functionality in the sitting position for routine activities. This study aims to investigate the effects of material selection in fabricating the 3D-printed adjustable headrest. Expected headrest users would be children (age seven to nine years old). There are five materials in this research: Polycarbonate (PC), Polylactic Acid (PLA), Acrylonitrile Butadiene Styrene (ABS), Polyamide (Nylon), and Polyethylene Terephthalate (PETG). In the designing process, Computer-Aided Design (CAD) software focuses on designing the structure and Finite Element Analysis (FEA) software to analyze various parts. To conclude this study, PLA is chosen as the best material based on the best stress, deformation, and safety factors.
