Since commercially available profiling systems fail when determining the surface roughness of porous materials, we propose a novel protocol for surface roughness quantification of 3D additive manufactured porous structures based on high-resolution microfocus X-ray computed tomography (micro-CT) images. It allows to non-destructively assess the roughness of these porous materials at the outer surface as well as inside the structure. The noise in the images and the spatial image resolution both have a significant effect on the accuracy of the micro-CT-based roughness measurements. Comparing the roughness parameters of flat substrates determined both with commercially available (optical and contact) profiling systems and the micro-CT-based roughness measurement protocol shows that micro-CT can be applied accurately and in a robust manner for surface roughness quantification of 3D additive manufactured porous materials with a micro-scale roughness. Depending on the dimensions of the roughness, the micro-CT acquisition parameters, i.e., frame averaging and spatial image resolution, need to be fine-tuned. Submicron-scale roughness can currently not be quantified. [less ▲]

Additive manufacturing techniques can be used to produce micro-porous structures with global morphological properties that are highly controlled through robust computer design. Despite these advantages, most of these techniques still hold several functional constraints, resulting from present technical device limits and consequently the inability to control surface morphology at a microscale level. In this study, a novel protocol for surface modification of 3D titanium alloy-based open porous structures is developed, which applies a combination of chemical etching (CHE) and electrochemical polishing (ECP) using HF-based solutions. This protocol achieves significant and controllable roughness reduction of additive manufactured 3D Ti6Al4V open porous structures. Chemical etching mainly removes the attached powder grains, while ECP further decreases the roughness. In this way the heterogeneity of the strut surface roughness throughout the full 3D structure is effectively removed. [less ▲]
