• Improving additive manufacturing processability of hard-to-process overhanging structure by selective laser melting (2017, background): “Therefore, external support structures are required during the fabrication of overhanging structures to fix the part to the building platform and conduct excess heat away from the part, hence preventing the warping and/or collapse (Calignano, 2014).”
• Manufacturability of AlSi10Mg overhang structures fabricated by laser powder bed fusion (2018, methodology): “Dross defects in LPBF are generally thought to be induced by the absorbed energy input, which is much higher at the powder-supported zone compared to the solid-supported zone; this situation further gives rise to the difference in molten pool size at the two zones [15].”
• An additive manufacturing filter for topology optimization of print-ready designs (2016, background): “Various strategies to automate the addition of minimal support structures have been proposed, see e.g. Strano et al. (2013), Vanek et al. (2014), and Calignano (2014).”
• Laser powder-bed fusion of Inconel 718 to manufacture turbine blades (2017, background): “Namely, an ideal balance must be found between two needs: reducing the amount of supports to preserve functional surfaces and allow the removal of the part; preventing warping and collapse of crucial surfaces exceeding a given threshold depending on both the material and the machine [36].”
• Topological design and additive manufacturing of porous metals for bone scaffolds and orthopaedic implants: A review. (2016, background): “includes overhanging structures, which may lead to some undesirable defects [120,121].”
• Investigation of the accuracy and roughness in the laser powder bed fusion process (2018, methodology): “The geometrical characteristics and surface roughness of the parts produced by L-PBF can be influenced by the orientation of the part on the building platform, the support structures required by process to conduct excess heat away from the part and to prevent the warping and/or collapse of the part ”
• Topology optimization of 3D self-supporting structures for additive manufacturing (2016, methodology): “Moreover, experiments show that small overhanging sections are in fact still printable [17, 14].”
