Frittage s\u00e9lectif par laser<\/h3>\n\n

L’impression par frittage s\u00e9lectif par laser, \u00e9galement appel\u00e9e fusion sur lit de poudre, est consid\u00e9r\u00e9e comme la technologie \u00ab b\u00eate de somme \u00bb des fournisseurs d’impression 3D, en raison des volumes de construction importants et d’une gamme de thermoplastiques techniques, ce qui en fait le choix parfait pour la fabrication en s\u00e9rie et les formes libres complexes pour les applications d’utilisation finale.<\/p>\n\n

Comment fonctionne le SLS ?<\/strong><\/p>\n\n

Une fine couche de poudre polym\u00e8re<\/a> pr\u00e9chauff\u00e9e est d\u00e9pos\u00e9e sur une plateforme de fabrication, puis fondue s\u00e9lectivement par un ou plusieurs lasers. La plateforme s’abaisse ensuite de l’\u00e9paisseur de couche d\u00e9finie, et une nouvelle couche de poudre est d\u00e9pos\u00e9e sur le lit. <\/p>\n\n

Le processus est r\u00e9p\u00e9t\u00e9 et les mat\u00e9riaux sont fusionn\u00e9s pour cr\u00e9er un objet 3D. Comme les technologies SLS ne n\u00e9cessitent pas de mat\u00e9riau de support suppl\u00e9mentaire, de nombreuses pi\u00e8ces peuvent \u00eatre fabriqu\u00e9es simultan\u00e9ment au sein d’une m\u00eame pi\u00e8ce, ce qui optimise la rentabilit\u00e9 et minimise les d\u00e9chets. La poudre non utilis\u00e9e peut \u00eatre renouvel\u00e9e et r\u00e9utilis\u00e9e, faisant du SLS 3D un proc\u00e9d\u00e9 de production durable. <\/p>\n\n
