title: An approach to computer aided porcelain forming system.
abstract: To examine a new concept for computerized production of dental prostheses, an experimental porcelain forming system was devised. Unlike other dental CAM systems, the system is intended to form porcelain much as human technicians do. The system builds up an object by alternately applying water and droplets of porcelain powder. Test specimens were made by forming porcelain powder into square plates under different forming conditions. Surface characteristics and shapes of formed porcelain were found to be affected by conditions such as quantity of water, forming area and forming thickness. The proper quantity of water for forming was influenced by evaporation. It was concluded that investigation into feedback control of the water supply in response to varying forming conditions is required.
