Additive manufacturing technology is the process in which material is manufactured using different additive processes. There are many additive processes such as Stereo lithography (SLA), Selective laser sintering (SLS), Fused deposition modeling (FDM), etc. FDM is most popular additive manufacturing process in which parts are manufactured in layers. Among all additive manufacturing technology, FDM process is the most versatile additive manufacturing process due to low cost, flexibility, broad range in material, low time consumption and accessibility. FDM process is the most economical process compare to other additive manufacturing processes. A study of wettability is basically depending on the process parameter such as layer thickness, build orientation, print speed and post processing method. In this research work, wettability of 3D printed PLA parts have been investigated at different raster angles. [ABSTRACT FROM AUTHOR]
