Both deliver strong, functional parts suitable for <a href=\"https:\/\/prototalgroup.com\/solutions\/rapid-prototyping\/\">prototyping<\/a> and end-use <a href=\"https:\/\/prototalgroup.com\/solutions\/serial-production\/\">serial production<\/a>. Both, technologies deliver comparable results.<\/p>\n\n<p class=\"wp-block-paragraph\">Di seguito, mettiamo a confronto MJF e SLS per aiutarti a determinare quale processo si adatta meglio alla tua applicazione e ai tuoi requisiti di produzione. Per non annoiarti con un lungo elenco di similitudini, in questo post ci concentriamo sulle differenze. <\/p>\n\n<h2 class=\"wp-block-heading\">Panoramica delle tecnologie MJF e SLS<\/h2>\n\n<h4 class=\"wp-block-heading\">Fusione a getto multiplo (MJF)<\/h4>\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/prototalgroup.com\/services\/industrial-3d-printing\/polymer\/mjf\/\">Multi Jet Fusion (MJF)<\/a>, developed by HP and introduced in 2016, is a relatively new but rapidly adopted\u00a0Industrial 3D Printing technology.<\/p>\n\n<p class=\"wp-block-paragraph\">Il processo MJF funziona come segue:<\/p>\n\n<ol class=\"wp-block-list\">\n<li>Uno strato sottile di polvere di polimero viene steso sulla piattaforma di costruzione.<\/li>\n\n\n\n<li>Un agente di fusione viene applicato selettivamente nei punti in cui il pezzo deve formarsi.<\/li>\n\n\n\n<li>Un agente per i dettagli affila i bordi e controlla la dispersione del calore.<\/li>\n\n\n\n<li>L&#8217;energia a infrarossi fonde la polvere in uno strato solido.<\/li>\n<\/ol>\n\n<p class=\"wp-block-paragraph\">Questo processo strato per strato produce pezzi con un&#8217;eccellente precisione dimensionale, resistenza isotropa e finiture superficiali uniformi. L&#8217;MJF viene spesso scelto quando sono richieste precisione, ripetibilit\u00e0 e velocit\u00e0 di produzione, soprattutto per i grandi volumi. <\/p>\n\n<h4 class=\"wp-block-heading\">Sinterizzazione laser selettiva (SLS)<\/h4>\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/prototalgroup.com\/services\/industrial-3d-printing\/polymer\/sls\/\">Selective Laser Sintering (SLS)<\/a> is a well-established and proven\u00a0Industrial 3D Printing technology\u00a0that has been used in demanding industries for decades.<\/p>\n\n<p class=\"wp-block-paragraph\">La SLS utilizza un laser ad alta potenza per fondere selettivamente la polvere polimerica, strato per strato, direttamente dai dati CAD. Dopo che ogni strato \u00e8 stato fuso, il letto di polvere si abbassa e viene applicato un nuovo strato di materiale. <\/p>\n\n<p class=\"wp-block-paragraph\">Le caratteristiche principali della SLS
