  • Process of simultaneously printing and electroforming ceramic articles
    Patent number: 4708781
    Abstract: A process of printing ceramic articles simultaneously with electroforming them to produce ceramic articles having patterns thereon comprises preparing a thin flexible diaphragm with a pattern thereon, applying the diaphragm to an electrode, immersing the electrode with the diaphragm thereon in a ceramic slip and applying electric current between the electrode as an anode and a counter electrode to deposit ceramic material on the electrode to form a green ceramic article to which the pattern is imparted by the diaphragm. The electrode with the diaphragm and green ceramic article thereon is removed from the ceramic slip and the diaphragm and article are together removed from the electrode. The article thus formed with the pattern thereon is thereafter dried and fired. The diaphragm is either left on the article and consumed during firing or is removed from the article before firing.
