Abstract: The present disclosure provides methods of making a vitreous bond abrasive article and a metal bond abrasive article. An abrasive article preform is produced by an additive manufacturing sub-process comprising the deposition of a layer of loose powder particles in a confined region and selective heating via conduction or irradiation to heat treat an area of the layer of loose powder particles. The loose powder particles include abrasive particles and organic compound particles, as well as vitreous bond precursor particles or metal particles. The abrasive article preform produced by additive manufacturing is subsequently heated to provide the vitreous bond abrasive article comprising the abrasive particles retained in a vitreous bond material, or to provide the metal bond abrasive article. Also, the methods include receiving, by an additive manufacturing device having a processor, a digital object specifying data for an abrasive article, and generating the abrasive article with the manufacturing device.

Abstract: A coated abrasive article maker apparatus is disclosed comprising a first web path comprising a production tool and a second web path configured for a resin coated backing. The second web path is configured to guide the resin coated backing through the coated abrasive article maker apparatus with the resin layer positioned facing the dispensing surface. An abrasive particle feeder is positioned along the first web path and is configured to dispense abrasive particles onto the dispensing surface such that abrasive particles are removably disposed within cavities of the production tool. Abrasive particles are transferred from the plurality of cavities to the resin layer of the resin coated backing when the production tool is positioned adjacent the resin coated backing.

The shaped abrasive particles have a longest particle lineal dimension on a surface and a shortest particle dimension perpendicular to the longest particle lineal dimension, and the longest particle lineal dimension is at least twice the shortest particle dimension. The shaped abrasive agglomerate particle has a longest agglomerate lineal dimension on a surface and a shortest agglomerate dimension perpendicular to the longest agglomerate lineal dimension, and the longest agglomerate lineal dimension is at least twice the shortest agglomerate dimension. The abrasive agglomerate particles are useful in abrasive articles. Methods of making the shaped abrasive agglomerate particle and abrading a workpiece are also described.
