Grain Refinement Caused by Larger Particles in Laser 3D Printing of AISI 304L Stainless Steel
Published on 2025-03-10 by Xuhuai Zhang, Xing Lu @MDPI
Abstract: Additively manufactured (AM) stainless steel has attracted a lot of attention for its competitive performance advantages over parts prepared by traditional methods. However, the influence of the powder characteristic of AISI 304L stainless steel on the laser 3D printing (3DP) process has yet to be clarified. In this research, the effect of the particle size of atomized AISI 304L stainless steel powder on 3DP of a powder-fed laser was studied, the grain morphology of different printed samples was[...]

Design Guide for Hybrid-Additive Manufacturing of Inconel 718 Combining PBF-LB/M and In Situ High-Speed Milling
Published on 2025-03-10 by David Sommer, Simon Hornung, Cemal Esen, Ralf Hellmann @MDPI
Abstract: As the correlation between design rules and process limitations is of the upmost importance for the full exploitation of any manufacturing technology, we report a design guide for hybrid-additive manufacturing of Inconel 718. Basic limitations need to be evaluated for this particular hybrid approach that combines laser powder bed fusion (PBF-LB/M) and in situ high-speed milling. Fundamental geometric limitations are examined with regard to the minimum feasible wall thickness, cylinders, overhang[...]

Characterization and Modelling of Biomimetic Bone Through Additive Manufacturing
Published on 2025-03-10 by Niranjan Srinivasan, Mohsen Barmouz, Bahman Azarhoushang @MDPI
Abstract: The long-term success of bone implant scaffolds depends on numerous factors, such as their porosity, mechanical properties, and biocompatibility. These properties depend on the type of material, such as metals and their alloys or ceramics, and the procedure used to create the scaffolds. This study aims to find the biomimetic properties of aluminum 6061 (Al 6061) alloy through Digital Light Processing (DLP) and sintering. Hollow cylindrical Al 6061 samples are printed through the DLP process at 9[...]
Our summary: Long-term success of bone implant scaffolds depends on porosity, mechanical properties, and biocompatibility. Study aims to find biomimetic properties of Al 6061 alloy through DLP and sintering. Scaffold model created with anisotropic properties closer to trabecular bone.
