Abrasive elements with precisely shaped features, abrasive articles fabricated therefrom and methods of making thereof

An abrasive article comprising:

• a plurality of abrasive features disposed on one or more abrasive elements, each of the one or more abrasive elements comprising a base having a first major surface from which the plurality of abrasive features extend;
• wherein a first set of the plurality of abrasive features (i) has an average height, H1avg, (ii) has a standard deviation of less than 10% of H1avg, and (iii) comprises between 5 and 130 abrasive features;
• wherein a second set of the plurality of abrasive features has (i) an average height, H2avg, and (ii) a standard deviation of less than 10% of H2avg, wherein H1ave is at least 5 microns greater than H2avg;
• wherein cross sectional areas of each of the plurality of features of the second set of plurality of abrasive features (i) taken in a plane that is parallel to the first major surface of the bases, and (ii) at a position along the second set of abrasive features that is 50% or less of the H2avg, cumulatively, is at least 5% of the cumulative projected areas of the of the one or more abrasive elements.
