The Effect of Infill Angle and Build Orientation on the Impact Strength and Production Time of Porous Infill Structure

In developing a lightweight structure, the density of structure can be reduced by converting solid to porous infill structure. Previous research has investigated that triangular highest impact strength compared other patterns. However, this may still improved adjusting parameters without extending production time. This goal is investigate effect build orientation and angle on time To achieve goal, uses 3D printing process manufacture made Polylactic Acid. Seven levels two are used find effect. experiment, twenty-six Charpy Impact specimens printed using Fused Deposition Modelling machine. Each specimen according ISO 179 standards tested GT-7045 testing machine measure specimen. The results experiment indicate resistance on-edge load better than flat orientation. type requires less for each angle. use 45-degree exhibits resistance. shortest time, 0-degree recommended.
