Fabrication and analysis of three-dimensional object using layerwise manufacturing technology

Abstract

Layerwise manufacturing technology exhibits a high potential in the field of rapid manufacturing, due to its capability to directly build up three-dimensional metallic components. In this research, we established a layerwise manufacturing platform having YLR 500 AC fiber laser and an enclosed chamber vacuumed and infused trace argon gas to minimize oxidation powdered material. From relationship of laser power and scanning speed can observe the variation of weld width. It assists to find the suitable laser parameters for laser additive manufacturing at blue region. The morphology of titanium specimen was analyzed by SEM image examined, and some porous structure formed due to the surface tension and oxide effect. The result of mechanical strength of 366.16 MPa was proved to be smaller than common bulk material. The X-ray diffraction patterns of titanium specimen has higher crystallization from R(110), R(101) and R(200). We have successfully fabrication a three-dimensional object and analysis its material properties.
