Abstract

Menetelmä, jossa muodostetaan esine esinetulostuksella rakennuskammiossa, poistetaan vapaata jauhetta rakennuskammiosta poistokanavan kautta, poistettu vapaa jauhe johdetaan kierrätyskokoonpanoon, joka on virtausyhteydessä poistokanavaan, ja missä poistettu vapaa jauhe kierrätetään aikaansaamalla jauhevirtaus kierrätyskokoonpanosta rakennuskammioon. Lisäksi sisältyy laitteisto ja rakennuskammio.
