... determine the surface profile and consequently significantly influence the surface roughness. Design/methodology/approach In this study, the conditions under which different modes of melt pool formation (conduction mode and keyhole mode) occur for the case of as-fabricated Hastelloy X using direct metal...

... of this paper is to present a parametric study and optimisation of fundamental parameters, including scan power, speed, inclined angle and layer thickness on surface roughness during selective laser melting of Hastelloy X. Design/methodology/approach Parametric significance on surface finish was analysed...
