Outline of Final Research Achievements

All-ceramic artificial teeth were fabricated using resin 3D-printer and high-speed centrifugal compaction process (HCP). Thin walled shell type resin molds were made by the printer, in which ceramic powders were successfully compacted by the HCP. Mold releasing was easy because of the use of the shell type molds.
Alumina and zirconia artificial teeth with 99% in sintered densities were obtained by the process.
