20.500.12556/RUL-179055 Modeling the surface hardness of metal materials produced by 3D selective laser melting The present study introduces a novel approach for pattern recognition to analyze the surface hardness of metal parts made by 3D selective laser melting (SLM). A printed part’s hardness is further influenced by post-processing, printing parameters, and post-print material handling. Layer by layer, material is deposited in 3D printing, sometimes referred to as additive manufacturing, to turn a digital design into a tangible product. More complex and adaptable designs are possible because 3D printing adds material rather than removes it, in contrast to conventional manufacturing techniques (such as machining or molding). The current work models the surface hardness of 3D selective laser melting of metal materials using genetic programming and network theory. To assess the hardness of 3D selective laser melting of metal materials, we introduce a novel pattern recognition technique. We apply fractal geometry analysis to determine the complexity of 3D selective laser melting of metal materials. additive manufacturing selective laser melting surface hardness fractal geometry network theory genetic programming true false true Angleški jezik Ni določen Članek v reviji 2026-02-04 14:40:21 2026-02-04 14:40:25 2026-02-05 04:27:09 0000-00-00 00:00:00 2026 0 0 8 str. 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.1/.2:004.45 0268-3768 10.1007/s00170-025-17268-y 267320835 https://link.springer.com/article/10.1007/s00170-025-17268-y 1 00d212f3-01cf-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=227171 Cali_..._Modeling_the_surface_hardness.pdf Cali_..._Modeling_the_surface_hardness.pdf 1 5A86561B30FBD6C88A52D4F78D4CD411 c898140943bf05bbaf7ef23f5d8fd45e9c24580d54553df3a275eaad17775b1f bb7be425-01d0-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=227174 Fakulteta za strojništvo 0 0 0
