Abstract Scope |
The metal additive manufacturing (AM) method of laser powder bed fusion (LPBF) relies upon the formation of uniform, densely packed, and defect free spread powder layers. The direct measurement of spread powder layer quality is challenging owing to the fine size of the powder bed features and limited selection of instruments which can assess the powder bed in-situ. This work assesses the fitness of a laser line profiling instrument in the measurement of an LPBF system powder bed. The ability of the instrument to detect macroscopic powder bed defects is shown. Additionally, results which assess the minimum resolvable feature size are presented, which suggest the instrument can capture microscopic powder bed defects. Measures of bed quality which may relate to end-component quality are examined. |
