In this study, border parameter optimization for F357 (AlSi7Mg) alloy processed using LPBF was performed with the aim of reducing the as-fabricated surface roughness. The optimization revealed that laser power and scanning speed can significantly influence the surface roughness of cube vertical surfaces. Measured areal average surface roughness (S<\/span><\/span><span class=\"TextRun SCXW107586394 BCX0\" lang=\"EN-CA\" xml:lang=\"EN-CA\" data-contrast=\"none\"><span class=\"NormalTextRun Subscript SCXW107586394 BCX0\" data-fontsize=\"11\">a<\/span><\/span><span class=\"TextRun SCXW107586394 BCX0\" lang=\"EN-CA\" xml:lang=\"EN-CA\" data-contrast=\"none\"><span class=\"NormalTextRun SCXW107586394 BCX0\">) for cube samples varied from 15 to 24 \u00b5m. The cube-based optimized parameters were used to fabricate angled wall samples with angles ranging from 45\u00b0 to 90\u00b0. The surface roughness reduced when the built angle increased from 45\u00b0 to 75\u00b0, while for 75\u201390\u00b0, the surface roughness values remained constant.<\/span><\/span><\/p>\n<p>&nbsp;<\/p>\n<p class=\"link-btn-style btn-yellow\"><a href=\"https:\/\/www.mdpi.com\/2673-4591\/43\/1\/8\" target=\"_blank\" rel=\"noopener\">Read the publication<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Singh Dhillon, J.; Su, S.; Sanchez Mata, O.; Ramakrishnan, T.; Brochu, M.
