Results from porosity measurements performed on 3D printed samples. Each point represents the average porosity (in percentage) found in six samples fabricated in five particular iterations. Red bars indicate standard deviation from this value. The dashed line represents the average porosity obtained from these five values [14]. Copyright 2014.
