Materialographic preparation of specimens produced by 3D-printing technologies

This report presents the complete materialographic preparation workflow for additive-manufactured Ti-6Al-4V samples produced by laser powder build-up welding. It covers cutting, cold mounting, grinding, polishing, etching, and microstructural characterization, including hardness mapping with over 120 measuring points. The document highlights optimized preparation parameters, equipment recommendations, and insights into the alpha–beta titanium microstructure.
