Abstract Scope |
The Laser Power Bed Fusion (L-PBF) process is well suited for manufacturing a wide range of complex geometries across a range of different processing conditions and alloys. Similarly advances in on- and off-axis monitoring techniques, machine sensors, and toolpath generation enable the concurrent creation of high-fidelity digital data as parts are produced. Unfortunately, the traditional evaluation methods for L-PBF components are often time consuming, segmented, and in certain cases lower resolution than the digital data. This work offers a new approach using high throughput CT-scanning method that is capable of analyzing a wide range of geometries and process conditions in a similar time to which the parts were produced. This technique provides the ability to map geometric and material quality data directly to the machine, monitoring, geometry framework. This data is used in a first step to show the impact of geometry and processing conditions on the resultant material. |
