20.500.12556/DiRROS-17649 The microstructure, mechanical and electrochemical properties of 3D printed alloys with reusing powders CoCrMo and Ti6Al4V are widely used in medical, dental and 3D printing technology, allowing the accurate fabrication of geometrically complicated structures. In order to reduce the costs of printed objects, the reuse of powder is common daily practice. AQ1 When using 3D printing technology, the direct impact of elevated temperatures and the influence of the laser beam may change the properties of the powder when it is reused, thus affecting the final properties of the printed object. The main aim of the present study was to investigate the impact of reused powder on the mechanical, microstructural and electrochemical properties of 3D printed objects. 3D printed objects fabricated from virgin and reused powder of both alloys were analyzed by metallographic observation, computed tomography, XRD and electrochemical methods. The main finding of the study was that the use of reused powder (recycled 3 times) does not detrimentally affect the mechanical and corrosion integrity of 3D printed CoCr and Ti6Al4V alloys, especially for the purpose of applications in dentistry. additive manufacturing selective laser melting virgin powder reused powder microtomography aditivne tehnologije selektivno lasersko taljenje nov prah ponovno uporabljen prah mikrotomografija true false true Nature Publishing Group Angleški jezik Slovenski jezik © The Author(s) 2023 Neznano 2024-01-08 08:15:10 2024-01-08 08:15:10 2024-01-09 03:37:07 0000-00-00 00:00:00 2023 0 0 Received: 6 September 2022 / Accepted: 27 January 2023; Nasl. z nasl. zaslona; Opis vira z dne 21. 2. 2023; str. 1-16 article no. 3245 Vol. 13 24.
