Fatigue and impact properties of 3D printed PLA reinforced with kenaf particles

The increasing demand on the production of ankle-foot orthosis (AFO) leads to implementation 3D Printing technology into manufacturing process, due its fast production, good design optimization, and cost-effectiveness. Now, several research works were made implement natural composite as Printer filament increase sustainability material, well reduce AFO's weight raw material cost. However, since this AFO will be used a daily basis, it is significant understand weight, fatigue impact strength they affect user's safety. aim paper investigate density, printed kenaf/PLA for possible usability AFO. filler within was varied at 3, 5 7 wt. % extruded obtain filament, which with printer print out specimens impact, test. As amount fillers increased, density resistance decreases while life increases. In conclusion, results found in tests show positive perspective towards
