Sintered fine ceramic or ceramic article, e.g. porcelain model for product development, roof tile model or technical ceramic, is produced by program controlled layer-wise laser sintering of solid ceramic granules

摘要

A sintered fine ceramic or ceramic article, produced by program controlled layer-wise laser sintering of solid ceramic granules, is new. An Independent claim is also included for solid fine ceramic or ceramic granules for carrying out the above process, produced by subjecting a fine ceramic or ceramic suspension to sieving to 63 or 100 microns size, purification, fluidized bed drying, sieving to 100-200 microns size, firing at 600-900 deg C or higher and sieving to 100-200 microns size.
