Additive Manufacturing (AM) technologies have high potential in terms of productivity and competitiveness for companies, their diffusion is still relatively limited among manufactures and end users. AM technology have different categories such as Material Extrusion, VAT Photopolymerisation, Powder Bed Fusion, Material Jetting, Binder Jetting, Sheet Lamination, Directed Energy Deposition. Fused deposition modeling (FDM) under Material Extrusion category is one of the most common and widely used additive manufacturing technology. FDM process is the most versatile additive manufacturing process due to low cost range, flexibility, broad range in material, low time consumption and accessibility. A study of dimensional accuracy, surface roughness & wettability are basically depending on the process parameter such as layer thickness, build orientation, print speed and post processing methods. In this research work, dimensional accuracy, surface roughness & wettability of 3D printed ABS; PLA & PP parts have been investigated at different raster angle.

Additive manufacturing, fused deposition modelling, surface roughness, dimensional accuracy, wettability.
