Abstract Scope |
The complexities of laser-material interaction for laser powder bed fusion require innovative approaches to accelerate material adoption. A combination of physics-driven LPBF processing diagrams, melt pool simulations, beam path planning, and advanced material characterization including X-ray computed tomography, in situ optical tomography, and in situ powder bed imaging can be used in the process parameter development cycle. An example of this workflow is illustrated for LPBF of high reflectivity materials such as Cu and Al alloys, which poses processing challenges of porosity and cracking. Our efforts to careful control of vaporization during LPBF are expected to lead to high density parts for such challenging alloys. |
