| Outline of Final Research Achievements |
We developed a method to improve the form accuracy and the soundness of the objects in the highly efficient additive manufacturing method of using the arc discharge as a heat source and wire supply. By this method, 1) It was clarified that it is possible to refine the metal crystal during solidification and to improve its strength by performing aggressive cooling. 2) A system that monitors the temperature and shape of the object was developed and the information can be fed back to the fabricating conditions, then it was made possible to improve the fabricating accuracy of the object.
