出来ないという欠点がある。This method has problems such as difficulty in marking minute parts and complexity in maintaining and managing printing quality. Recently, a laser marking method has been used in which the surface of an article such as a part is directly irradiated with a laser beam, and a portion of the surface disappears by evaporation or thermal decomposition. However, there are various materials for the articles to be marked, and there is a drawback that clear markings cannot be made depending on the material.
