Abstract
Additive manufacturing (AM) offers numerous advantages like unlimited freedom to design the most complicated parts without expensive support tools and moulds at reduced lead-times. However, AM is not completely established to meet compliance of industrial standards due to intrinsic fabrication process induced rougher surface quality and poor dimensional tolerance especially the inclined and curved AM components. It is paramount to address the evolution of surface irregularities such as the staircase effect, the spatters, the adhered un-melted or partially-melted particles that impart poor surface quality on the inclined and curved metal AM surfaces. Hence, this research is focused on investigating the emergence of surface irregularities and their impact on the resultant surface texture with respect to various surface inclination angles. Focus variation measurement (FVM) method is employed to acquire the surface topography of bespoke metal truncheon artefact produced by SLM with various surface inclinations from 0o to 180o. The areal surface texture characterization and the particle-based feature analysis reveal that there exists a strong intertwining relationship between the resulted surface topographies and the surface inclination angles.
