Effect of Raster Angle on the Mechanical Properties of PLA 3D Printed Articles

Fused deposition modeling (FDM) has been emerged as the most popular additive manufacturing technologies to make the engineering components within a short span of time. In this method, 3D digital CAD data is converted directly to make a product. In the present investigation, the mechanical properties of FDM printed specimens were evaluated according to Iso- 527A-5A. The specimens were printed using PLA filament at different raster angles of 0º/90o, ±45º and 60º/-30o. It was found that the raster angle is an important parameter which significantly affected on the mechanical properties of the specimens. The results showed that the tensile strength decreased with the increase in the raster angle
