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.

Use of Biobased Resins Derived from Renewable Monomers for Sustainable 3D Fabrication Through Two-Photon Polymerization
Published on 2025-03-10 by Francisco Gontad, Jaime Cuartero, Sara Vidal, Nerea Otero, Natalia M. Schulz, Tobias Robert @MDPI
Abstract: This work demonstrates the fabrication of microstructures with formulations containing bio-based prepolymers derived from itaconic acid, commercial reactive diluents, photo initiators, and inhibitors, through two-photon polymerization. Lateral and vertical resolutions within the micron range can be achieved by the adjustment of laser scanning speed and pulse energy, and through the use of microscope objectives with high magnification and numerical aperture. The fabrication throughput can be slig[...]

Mechanical Behavior of SLS-Printed Parts and Their Structural Simulation
Published on 2025-03-05 by Tamara van Roo, Conor J�rg Mager @MDPI
Abstract: This study aims to assess the mechanical tensile properties of Polyamide produced via selective laser sintering (SLS). The research focuses on the effects of post-processing, positional dependency, anisotropy, and the repeatability of SLS print jobs on material properties. Understanding this anisotropy is crucial for reliable component simulation. A design-appropriate simulation method is developed. A total of 27 identical specimens were fabricated in various orientations and positions within th[...]
Our summary: This study evaluates the mechanical properties of SLS-printed Polyamide, focusing on post-processing effects, positional dependency, and anisotropy. A new simulation method is developed based on orthotropic material modeling in ANSYS, showing significant anisotropy with z-position affecting mechanical properties.
