Cross-sectional scanning electron microscopy (SEM) measurements were taken on an Inconel 625 sample, created with binder-jet printing, and sintered at 1285 C degrees for 0.5 hours. This sintering temperature is above the solidus line for liquid-state sintering. Print parameters: Powder preparation: nitrogen gas atomization Particle distribution: 16 – 63 microns Mean particle size: 20 – 25 microns Layer thickness: 100 microns Nozzle spacing: 64 nozzles in parallel with the print head Sample Orientation: the build direction is in the positive z direction, the print bed movement is on the x-axis, and the roller direction is on the y-axis. The surface measured on this sample is the positive y-face of orientation Surface Topography data for this surface was collected on a scanning electron microscope (Sigma 500VP, Zeiss, Oberkochen, Germany) with the secondary-electron detector. The data is associated with the following publication: Brown, C., Nescio, M., Chadha, V., Zheng, C., Abelev, E., Chmielus, M., and Jacobs, T.D.B.
