dc.description.abstractThe cleaning procedures of implant materials which are manufactured by additive manufacturing have not been standardized despite many studies. Most studies suggest successful cleaning procedures and provide good results to their areas of use. Failure to remove unmelted powder and impurities remaining on the surface may cause serious problems such as inflammation, tissue incompatibility and reimplantation. Implants can also be manufactured as lattice structures with additive manufacturing methods and this situation makes the cleaning procedure more important due to biocompatibility. In this aspect, an acid etching procedure was proposed and its effect on lattice structures was examined. Acid etching procedure causes dimensional changes which can also affect the mechanical properties of lattice structures, therefore the acid etching process should be analyzed very well. In this study, Ti6Al4V thin strut lattice structures (0.25 mm) were manufactured by laser powder bed fusion technology (LPBF). Cubic samples of lattice structures were built on z-direction and their surfaces were examined in terms of topographical characteristics. As-built dimensional accuracy and selected lattice parameter measurements were compared with a scanning electron microscope (SEM) and a digital microscope before and after acid etching. The difference among the microscope measurements was found to be in the range of 0.001–0.035 mm. According to the results, KEYENCE and SEM measurement results were closest to each other in the star lattice structure when compared to other lattice structures in the range of 0.001–0.003 mm.
