Autor: Christophe Gadea, Tarek Spelta, Søren Bredmose Simonsen, Vincenzo Esposito, Jacob R. Bowen, Astri Bjørnetun Haugen
Publikováno v: Open Ceramics, Vol 6, Iss , Pp 100110- (2021)
Ink formulation is one of the main challenges with ceramic 3D printing. Here, we present a new, reactive-colloidal hybrid ink for 3D printing by robocasting of BaTiO3-based ceramics. The hybrid ink combines a titanium isopropoxide-based sol-gel base
