Effect of infill patterns on the mechanical performance of lightweight 3D-printed cellular PLA parts
Materials Today Communications(2018)
摘要
•The hexagonal structures show the best balance in mechanical performance.•The square structures exhibit the best performance under uniaxial tensile loading.•The square-diagonal structures present the least balance in mechanical performance.•The infill density is the limiting factor for using more perimeter shells.
