Effect of Process Parameters on the Surface Microgeometry of a Ti6Al4V Alloy Manufactured by Laser Powder Bed Fusion: 3D vs. 2D Characterization

The influence of the main process parameters, laser power, point distance and time exposure, on surface microgeometry Ti6Al4V specimens produced by a pulsed powder bed fusion was investigated. A 3D characterization carried out collected data were elaborated to reconstruct determine both 2D material ratio curves along different directions. curve gives slightly lower peak zone Mr1 higher valley Mr2, reduced height Rpk Rvk than curves. Roughness is greater in analysis one, skewness same kurtosis increases from <3 >3 3D. increase increasing decreasing exposure power. Within investigated ranges (27.3–71.2 J/mm3), an energy density reduces roughness while are not significantly affected. results indicate that approach allows better one.
