Abstract A comprehensive analysis of literature pertaining to surface texture metrology for metal additive manufacturing has been performed. This review paper structures the results of this analysis into sections that address specific areas of interest: industrial domain; additive manufacturing processes and materials; types of surface investigated; surface measurement technology and surface texture characterisation. Each section reports on how frequently specific techniques, processes or materials have been utilised and discusses how and why they are employed. Based on these results, possible optimisation of methods and reporting is suggested and the areas that may have significant potential for future research are highlighted.

Review of defects in lattice structures manufactured by powder bed fusion (2019, background): “In this regard, XCT is superior to optical instruments which rely on line of sight and consistent reflective properties— both of which are hindered by AM surfaces through features such as high slopes and variable aspect-ratios [112].”
