20.500.12556/RUL-154053 Advancements in metal additive manufacturing a comprehensive review of material extrusion with highly filled polymers Additive manufacturing (AM) has attracted huge attention for manufacturing metals, ceramics, highly filled composites, or virgin polymers. Of all the AM methods, material extrusion (MEX) stands out as one of the most widely employed AM methods on a global scale, specifically when dealing with thermoplastic polymers and composites, as this technique requires a very low initial investment and usage simplicity. This review extensively addresses the latest advancements in the field of MEX of feedstock made of polymers highly filled with metal particles. After developing a 3D model, the polymeric binder is removed from the 3D-printed component in a process called debinding. Furthermore, sintering is conducted at a temperature below the melting temperature of the metallic powder to obtain the fully densified solid component. The stages of MEX-based processing, which comprise the choice of powder, development of binder system, compounding, 3D printing, and post-treatment, i.e., debinding and sintering, are discussed. It is shown that both 3D printing and post-processing parameters are interconnected and interdependent factors, concurring in determining the resulting mechanical properties of the sintered metal. In particular, the polymeric binder, along with its removal, results to be one of the most critical factors in the success of the entire process. The mechanical properties of sintered components produced through MEX are generally inferior, compared with traditional techniques, as final MEX products are more porous. additive manufacturing debinding feedstock material extrusion metal injection molding metals sintering aditivna proizvodnja razvezovanje surovine iztiskanje materiala brizganje kovin kovine sintranje true false true Angleški jezik Slovenski jezik Članek v reviji 2024-01-22 13:16:01 2024-01-22 13:16:07 2024-01-23 03:38:32 0000-00-00 00:00:00 2024 0 0 26 str. no. 1, [article no.] 14 Vol. 8 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.9 2504-4494 10.3390/jmmp8010014 181929731 Sadaf...-Advancements_in_metal_additive_manufacturing.pdf Sadaf...-Advancements_in_metal_additive_manufacturing.pdf 1 75EFE4FCE2A3FAD31F004F852E602871 0f709773a020661b85f574fa0004d36ca752c373ef41001d2160740c4a8c32dc 63fd0231-b920-11ee-88cd-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=180202 https://www.mdpi.com/2504-4494/8/1/14 1 05c91953-b920-11ee-88cd-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=180201 Fakulteta za strojništvo 0 0 0
