Sažetak
Selective laser melting (SLM) technique is used to produce Co-Cr dental prosthodontic appliances with generally insufficient relevant material properties information. Experimental work was conducted on specimens made from the commercial Co-Cr dental alloy powder for SLM production on machines from three different manufacturers. Recommended production parameters which fulfill the requirements for Co-Cr dental materials, according to EN ISO 22674, were used. Specimens were used for tensile, three-point bending, and toughness tests. Optical and SEM analyses of microstructure were performed on the same specimens. Although specimens were made according to EN ISO 22674, with the same process and under the recommended production parameters, significant differences in microstructures and mechanical properties were determined. The paper will consider the impact of three different types of SLM machines on the structure and mechanical properties of 3D printed Co-Cr dental alloy.
