| Abstract Scope |
There are many limitations to the achievable productivity and the deeper understanding of a single laser SLM system. For productivity some of these include laser beam diameter, laser power, layer thickness, laser beam profile, and laser speed. For understanding some of these include the ability to monitor, measure, and analyze on spatial and temporal scales that are harmonized with the process itself. This work describes a new machine system leveraging a programmable laser technology enabling a hybrid toolpath workflow that uses different laser profiles within a single optical processing head. Furthermore the need in such a system for adaptive control over parameters such as laser power as a function of process dependent variables such as toolpath and geometry. Monitoring has been performed to understand the impact of non-Guassian energy profiles on melt pool dynamics, spatter generation, and coaxial monitoring signature. |
