Data on Hausner Ratio of Polyamide 12 (PA12) in Polymer Selective Laser Sintering

The CSV file contains the raw Polyamide 12 (PA12) Hausner ratio data in Table 2. The measurement method was modified from ASTM C1444. The powder measurement container is a pre-weighted 100 ml graduated cylinder. In bulk density measurement, the powder was filled into the container along its side wall. The volume reading and the total weight were documented for bulk density calculation. After the bulk density measurement, the powder-filled container was placed on a Vortex-Genie 2 lab mixer for three minutes followed by 10 manual taps to condense the powder. The tapped powder volume was then documented for tapped density calculation. The Hausner ratio was then calculated based on bulk density and tapped density.
