The invention relates to a ceramic scraper, which is used for powder spreading in the process of laser rapid prototyping. Both ends of an edge are provided with rounded corners, the upper part of the scraper is provided with screw holes, and thereby the ceramic scraper can be conveniently fixed on a scraper holder of a powder spreader. Since a conventional steel scraper has high ferromagnetism, in the process of powder spreading, the steel scraper can attract magnetic powder because of static electricity generated by friction, the magnetized powder can be easily agglomerated, as a result, the surface of a formed layer is uneven, the machining precision of parts is decreased, and even the interruption of a modeling process is caused. Since the ceramic scraper does not have ferromagnetism, the problems existing in the conventional scraper can be solved perfectly, the evenness of a powder layer is increased, and prototyping precision is improved. Moreover, since the rigidity of the ceramic scraper is high, the ceramic scraper has high wear resistance, furthermore, since the edge of the scraper is added with the rounded corners, friction force applied on the scraper can be further decreased, and therefore the service life of the scraper made of ceramic can be effectively prolonged. The ceramic scraper also has the advantages of simplicity in production, low machining cost, convenience in use and the like.
