20.500.12556/RUL-163452 Selective laser melting a novel method for surface roughness analysis Selektivno lasersko taljenje: nova metoda za analizo površinske hrapavosti The present study introduces a novel approach to analyse the surface roughness of metal parts made by 3D selective laser melting (SLM). This technology, known for its ability to efficiently produce functional prototypes and limited-run series, is particularly effective when surface conditions directly meet usage requir ements. Thus, the suitability of surfaces is a critical factor, emphasizing the importance of new methods for predicting their quality. Here fractal geometry and network theory are integrated to delve into the complexities of SLM-produced surfaces, while machine learning and pattern recognition concepts are employed to evaluate the surface roughness. Specifically, genetic programming, artificial neural networks, support vector machine, random forest, k-nearest neighbors are compared in terms of accuracy demonstrating that only the first method provided valid estimation due to the presence of very little training data. Experimental work with EOS Maraging Steel MS1 and an EOS M 290 3D printer validates the method’s practicality and effectiveness. Then, the research offers a fresh perspective in surface analysis and has significant implications for quality control in additive manufacturing, potentially enhancing the precision and efficiency of 3D metal printing. additive manufacturing selective laser melting surface roughness fractal geometry network theory genetic programming aditivna proizvodnja selektivno lasersko taljenje hrapavost površine fraktalna geometrija teorija omrežij genetsko programiranje true false true Angleški jezik Slovenski jezik Članek v reviji 2024-10-07 11:13:58 2024-10-07 11:14:05 2024-10-10 03:32:43 0000-00-00 00:00:00 2024 0 0 Str. 313-324 no. 7/8 Vol. 70 July-Aug. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.7.019:004.4 0039-2480 10.5545/sv-jme.2024.1009 209426179 Babic_..._Selective_laser_melting_-_a_novel_method_for_surface_....pdf Babic_..._Selective_laser_melting_-_a_novel_method_for_surface_....pdf 1 8983BCE29379A58DE8485E47407BEFD6 6b3b33e9aefa2c8e6863e9351699786a4d09e943de4394de737b8faf70094cc4 ccb7d899-848c-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=193149 https://www.sv-jme.eu/?ns_articles_pdf=/ns_articles/files/ojs30/1009/66cc2d6717e58.pdf&id=7068 0 bfb49488-848c-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=193148 Fakulteta za strojništvo Strojniški vestnik 0 0 0
