The results demonstrate a high correlation (r = 0.91) between femoral head and acetabular diameters, which supports the accuracy of the proposed regression formula for sizing components. The Artificial Neural Network (ANN) models successfully predicted biomechanical metrics such as stress, deformation, and strain with low error rates, including a stress error range of 3.03% to 7.18%. Mechanical testing of the 3D-printed Polylactic Acid (PLA) material showed a tensile strength of 72 MPa and stable deformation under simulated daily activities, with a maximum displacement of 0.580 mm. Additionally, the 3D-printed components achieved a high manufacturing precision with a 99.76% tolerance for femoral head diameter match to the original CAD designs, as verified through laser scanning and deviation analysis.<\/span><span style=\"font-family: Arial; font-size: 17px;\">\u00a0<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: Arial; font-size: 17px;\">The study concluded by recommending the importance of integrating research with healthcare sectors (hospitals and healthcare centers), to ensure that research, especially in automated manufacturing field, serves community, meets the need of hospitals, and providing artificial alternatives for patients using advanced technologies in the field of industrial automation.<\/span><span style=\"font-family: Arial; font-size: 17px;\">\u00a0<\/span><\/p>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;6547&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;6549&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;6551&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;6548&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row]<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>[vc_row][vc_column][vc_column_text css=&#8221;&#8221;] \u00a0On Thursday December 12th, 2025 a master thesis defense was held for the master &#8230; <a class=\"cz_readmore\" href=\"https:\/\/en.kecbu.uobaghdad.edu.iq\/?p=6545\"><i class=\"fa czico-132-arrows-8\" aria-hidden=\"true\"><\/i><span>more<\/span><\/a><\/p>\n","protected":false},"author":27,"featured_media":6547,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_lmt_disableupdate":"no","_lmt_disable":"","footnotes":""},"categories":[3,8],"tags":[],"class_list":["post-6545","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-latest-news","category-masters-discussions"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.8 -
