|Abstract: ||Layered manufacturing technologies have been used to produce complex parts
of diversified materials through different physical/chemical manufacturing
principles. Nevertheless only a few materials are commercially available to
build parts suitable for engineering applications. In this paper, the powder
fusion of H13 tool steel is investigated. A high power Nd:YAG pulsed laser
source on a CNC machine was used to fuse the powder, layer by layer, building
solid cubes for further analysis. Four different laser vector scanning strategies
were evaluated by comparing the results of porosity and layer distortion.
The complexity of the laser/powder interaction shows that a complex strategy
must be used to avoid porosity and distortion.|
