La seguente tesi di laurea magistrale si inserisce nell’ambito del Material and Engeneering Design, una branca del design che si concentra sulla progettazione, lo sviluppo e l’applicazione di materiali per creare soluzioni innovative ed efficienti per una vasta gamma di applicazioni industriali e tecnologiche. Questo campo integra conoscenze e competenze provenienti da scienze dei materiali, ingegneria, chimica e progettazione al fine di ottimizzare le proprietà dei materiali per scopi specifici. Grazie all’ausilio della manifattura additiva, la stampa 3D, la quale rappresenta una leva importante per la transizione verso un’economia circolare, è possibile fornire una seconda vita ai materiali di scarto mediante la creazione di un filamento non necessariamente performante. L’obiettivo della seguente tesi di laurea consiste nella creazione sperimentale di tre bio-filamenti (e pellet) per la stampa 3D FFF (Fused Filament Fabrication) prodotti dalla miscela composta dalla polvere di marmo (scarto industriale) come riempimento, e il PLA, come matrice, a tre diverse percentuali: 10%, 20% e 30%. Successivamente, i bio-filamenti sono stati caratterizzati dal punto di vista estetico, chimico e meccanico. In conclusione, nella definizione di un’ipotesi applicativa del materiale prodotto, si è individuata la possibilità di installare dei dispositivi, in polvere di marmo e PLA, nelle cave per contribuire alla loro rinaturalizzazione, in seguito ad uno studio specifico sulle proprietà dei materiali.
