Description

Raw surface profile data from a Zygo Zegage optical profilometer and scanning electron micrographs of the surfaces of NiTi channels fabricated by laser powder-bed fusion (L-PBF) with varying laser power, scan speed, hatch space, scan pattern, channel orientation, and channel diameter. A post-process electropolishing is performed and samples are re-measured. Please refer to the associated research article and Data in Brief below for more information.

Steps to reproduce

The L-PBF system that was used to produce two NiTi parts consisting of internal channels was a ProX 100, a commercial metal printer from 3D Systems. The two parts were either printed horizontally or vertically and each contain eight through-hole channels, 15 mm in length, with each channel comprised of three 5 mm length segments with different diameters.
