Principen utg\u00e5r fr\u00e5n att man med hj\u00e4lp utav metallpulver bygger upp sin detalj. Med hj\u00e4lp utav en laser s\u00e5 sm\u00e4lts detta metallpulver och produkten tr\u00e4der fram. Detta ger m\u00f6jligheten att skapa geometrier som med konventionell bearbetning aldrig hade varit m\u00f6jliga.<\/strong><\/p>\n\n\n\n<p>Detta arbete utf\u00f6rdes i samarbete med Uddeholms AB i Hagfors och m\u00e5let med arbetet var att standardisera deras interna tillverkningsprocess. Detta involverade att utveckla ett nytt, generellt fixtursystem som kan fixera och hantera de diverse geometrier som additiv tillverkning ger m\u00f6jlighet f\u00f6r. Bild ett (1) visar fixtursystemet i sin helhet medan bild tv\u00e5 (2) visar ett exempel p\u00e5 hur fixtur systemet anv\u00e4nds.<\/p>\n\n\n\n<p>Ut\u00f6ver detta fixtursystem s\u00e5 gjordes \u00e4ven en materialanalys. Detta f\u00f6r att kunna presentera och bist\u00e5 med optimerade parametrar f\u00f6r att uppn\u00e5 det b\u00e4sta resultatet. Materialanalysen visade att b\u00e4st resultat uppstod n\u00e4r man printade p\u00e5 en bas som var i leveranstillst\u00e5nd med en tunn lagertjocklek. Ut\u00f6ver detta s\u00e5 visade det sig \u00e4ven vara gynnsamt att anv\u00e4nda sig utav dubbel exponering, allts\u00e5 att lasern passerar lagret tv\u00e5 g\u00e5nger i st\u00e4llet f\u00f6r en, detta f\u00f6r att s\u00e4kerst\u00e4lla att inget osm\u00e4lt metallpulver finns kvar. De parametrar som studerades var porositet samt h\u00e5rdhet, bild tre (3) visar h\u00e5rdhetsprofilen hos de rekommenderade parametrarna.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-1 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"451\" data-id=\"197\" src=\"https:\/\/sola.kau.se\/hingiodexamensarbeten\/wp-content\/uploads\/sites\/878\/2023\/06\/Render_2-1-1024x451.png\" alt=\"\" class=\"wp-image-197\" srcset=\"https:\/\/sola.kau.se\/hingiodexamensarbeten\/wp-content\/uploads\/sites\/878\/2023\/06\/Render_2-1-1024x451.png 1024w, https:\/\/sola.kau.se\/hingiodexamensarbeten\/wp-content\/uploads\/sites\/878\/2023\/06\/Render_2-1-300x132.png 300w, https:\/\/sola.kau.se\/hingiodexamensarbeten\/wp-content\/uploads\/sites\/878\/2023\/06\/Render_2-1-768x339.png 768w, https:\/\/sola.kau.se\/hingiodexamensarbeten\/wp-content\/uploads\/sites\/878\/2023\/06\/Render_2-1-1140x502.png 1140w, https:\/\/sola.kau.se\/hingiodexamensarbeten\/wp-content\/uploads\/sites\/878\/2023\/06\/Render_2-1.png 1359w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Fixtursystem (Bild 1)<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"989\" height=\"531\" data-id=\"195\" src=\"https:\/\/sola.kau.se\/hingiodexamensarbeten\/wp-content\/uploads\/sites\/878\/2023\/06\/Example_both-1.png\" alt=\"\" class=\"wp-image-195\" srcset=\"https:\/\/sola.kau.se\/hingiodexamensarbeten\/wp-content\/uploads\/sites\/878\/2023\/06\/Example_both-1.png 989w, https:\/\/sola.kau.se\/hingiodexamensarbeten\/wp-content\/uploads\/sites\/878\/2023\/06\/Example_both-1-300x161.png 300w, https:\/\/sola.kau.se\/hingiodexamensarbeten\/wp-content\/uploads\/sites\/878\/2023\/06\/Example_both-1-768x412.png 768w\" sizes=\"auto, (max-width: 989px) 100vw, 989px\" \/><figcaption class=\"wp-element-caption\">Exempel p\u00e5 anv\u00e4ndning (Bild 2)<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"914\" height=\"494\" data-id=\"196\" src=\"https:\/\/sola.kau.se\/hingiodexamensarbeten\/wp-content\/uploads\/sites\/878\/2023\/06\/Finalparameters-1.jpg\" alt=\"\" class=\"wp-image-196\" srcset=\"https:\/\/sola.kau.se\/hingiodexamensarbeten\/wp-content\/uploads\/sites\/878\/2023\/06\/Finalparameters-1.jpg 914w, https:\/\/sola.kau.se\/hingiodexamensarbeten\/wp-content\/uploads\/sites\/878\/2023\/06\/Finalparameters-1-300x162.jpg 300w, https:\/\/sola.kau.se\/hingiodexamensarbeten\/wp-content\/uploads\/sites\/878\/2023\/06\/Finalparameters-1-768x415.jpg 768w\" sizes=\"auto, (max-width: 914px) 100vw, 914px\" \/><figcaption class=\"wp-element-caption\">H\u00e5rdhetsprofil (Bild 3)<\/figcaption><\/figure>\n<\/figure>\n","protected":false},"excerpt":{"rendered":"<p class=\"post-excerpt\">Patrik Andersson I dagens samh\u00e4lle s\u00e5 blir additiv tillverkning alltmer vanlig.
