Abstract Scope |
Although PBF-LB/P is one of the most promising additive manufacturing technologies for part production, the industries that use it are limited. One reason for this limitation is the production cost of PBF-LB/P, which can be reduced by increasing process efficiency, such as production speed. In this study, to improve the production speed of PBF-LB/P, we attempted to expand the layer pitch, which is called the layer thickness, that is, the distance of platform movement per layer. The layer pitch can affect the interlayer adhesion or part strength. Herein, the relationship between layer pitch and tensile strength in the z-direction was investigated. Because the energy required to melt the supplied powder per layer also varies with the layer pitch, process parameters such as the energy density of laser exposure per layer were adjusted when the specimens were built. |
