Le partenaire<\/h5>\n\n\n\n

Pres-X <\/a>est une entreprise italienne sp\u00e9cialis\u00e9e dans la fabrication additive et en particulier sur les op\u00e9rations de post-traitement. Sa maison m\u00e8re, BEAMIT<\/a>, souhaite fournir des composants m\u00e9talliques haut-de-gamme pour l\u2019industrie et constitue une plate-forme offrant une cha\u00eene de valeur compl\u00e8tement int\u00e9gr\u00e9e.<\/p>\n\n\n\n

L\u2019application<\/h5>\n\n\n\n

La fusion laser sur lit de poudre<\/strong>, plus commun\u00e9ment appel\u00e9e LPBF<\/strong>, est un proc\u00e9d\u00e9 de fabrication additive. En parcourant une certaine trajectoire sur un lit de poudre m\u00e9tallique et en r\u00e9alisant donc la fusion du m\u00e9tal sur son passage, un laser haute puissance continu permet d\u2019imprimer la pi\u00e8ce par couches successives.<\/p>\n\n\n\n

La probl\u00e9matique<\/h5>\n\n\n\n

Le proc\u00e9d\u00e9 LPBF est confront\u00e9 \u00e0 deux d\u00e9fis majeurs. D\u2019un c\u00f4t\u00e9, il est indispensable d\u2019en augmenter la productivit\u00e9<\/strong> afin de pouvoir r\u00e9aliser des pi\u00e8ces en grand volume et \u00e0 une cadence \u00e9lev\u00e9e, de l\u2019autre, une ouverture \u00e0 l\u2019impression de nouveaux mat\u00e9riaux<\/strong> permettrait d\u2019am\u00e9liorer la flexibilit\u00e9 de ce proc\u00e9d\u00e9.<\/p>\n\n\n\n

La solution CANUNDA-HP Custom Shaper<\/h5>\n\n\n\n

Les modules CANUNDA-HP Custom Shaper sont des syst\u00e8mes permettant de g\u00e9n\u00e9rer des mises en forme statiques ou dynamiques de faisceaux laser continus \u00e0 haute puissance sur mesure.<\/p>\n\n\n\n

Bas\u00e9s sur la technologie MPLC et de conception toute r\u00e9flective, ils sont capables de g\u00e9rer de tr\u00e8s hautes puissances et sont adaptables \u00e0 tous les environnements industriels.<\/p>\n\n\n\n

Int\u00e9gration industrielle du module CANUNDA-HP Custom Shaper<\/h5>\n\n\n\n

Le module multistatique CANUNDA-HP Custom Shaper a \u00e9t\u00e9 install\u00e9 sur une machine de fabrication additive dans les locaux de PRES-X et a permis la fabrication de pi\u00e8ces en Inconel 939<\/strong>, alliage de Nickel auparavant impossible \u00e0 fabriquer avec cette machine, gr\u00e2ce \u00e0 la r\u00e9duction de la fissuration lors de la solidification.<\/p>\n\n\n\n

CANUNDA-HP Custom Shaper a permis la g\u00e9n\u00e9ration de trois mises en forme : une forme annulaire pr\u00e9sentant un diam\u00e8tre moyen de 150 \u00b5m avec une largeur de tore \u00e0 mi-hauteur (FWHM) de 70 \u00b5m ; une forme elliptique de dimensions 90 \u00b5m x 280 \u00b5m @1\/e\u00b2 et une forme top-hat rond de diam\u00e8tre 90 \u00b5m @1\/e\u00b2<\/strong>. Les meilleurs r\u00e9sultats ont \u00e9t\u00e9 obtenus avec la mise en forme top-hat rond : une fen\u00eatre de proc\u00e9d\u00e9 plus large, des propri\u00e9t\u00e9s micrographiques et m\u00e9caniques sup\u00e9rieures.<\/p>\n\n\n","protected":false},"excerpt":{"rendered":"
