This study aims to fabricate the micro-structured parts using nano-powder via compaction process by printing. The sacrificial plastic mold (SP-mold) which is derived from melting nanofiber produced by electron spinning (ES) method which provides a simple and versatile method for generating ultra-thin fibers using variety of materials is used. The original form made of silicon has micro-sized structures with line and space patterns, circular hole or column. The material used for printing is the mixture of nano-scale Ni or TiO2 powders and water-soluble binder. It was shown from the results of surface observation that the SP-mold with micro-structures of 1 micron wide and 10 micron high in minimum size could be obtained finely, and also the sound sintered parts were obtained.
