Abstract

Per fabbricare in maniera semplice un albero a camme da un albero base (2) e da parti stampate (1) che vengono formate a partire da un miscuglio di polveri di sinterizzazione e vengono sinterizzate in fase liquida sull'albero base (2), si propone, per posizionare le parti stampate (1), di imprimere su uno dei loro lati frontali cavità (5) per inserti di sostegno (3) inseribili nell'albero base (2) e di far scorrere le parti stampate (1) sull'albero base (2) fino all'impegno degli inserti di sostegno (3) nelle cavità (5) prima che le parti stampate (1) che appoggiano sugli inserti di sostegno (3) dell'albero base (2) disposto verticalmente vengano sinterizzati con fase liquida.
