Dimensional accuracy and stability analysis of laser powder bed fusion (LPBF) samples: implications of process variables
https://orcid.org/http://orcid.org/0000-0002-3550-3906
This study examines the precision and durability of samples produced through laser powder bed fusion (LPBF), a widely adopted additive manufacturing technique known for its exceptional performance. This study involved fabricating a flat sample featuring curved elements, with the build direction aligned along the Z-axis, while the flat surfaces were oriented in the XY direction. The sample’s width, length, and radius of curvature distances were measured using a coordinate measuring machine (CMM). The nominal values were used as a reference to compare the measured dimensions of the sample. The results indicated that the sample length was slightly shorter than the nominal values. However, all measured values had a percentage error within the allowed ranges. The direction of the dimension that was evaluated, such as the X, Y, or Z direction, may affect the dimensional stability of the sample. Dimensional stability exhibits favourable performance when the energy density falls within the 58 to 81 J/mm3 range. This work studied how the process variables influenced the dimensional stability of heat-treated samples.
