The present paper studies the effect of in-plane raster orientation on the tensile and fracture strengths of poly-lactic acid (PLA) samples made by fused deposition modeling technique. Four different raster angles of 0/90°, 15/−75°, 30/−60°, and 45/−45° are selected for the dog-bone and the semi-cir...
