Abstract: The present disclosure provides methods of making a vitreous bond abrasive article and a metal bond abrasive article. The methods include sequential steps. Step a) includes a subprocess including sequentially: i) depositing a layer of loose powder particles in a confined region; and ii) selectively applying heat 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 layer of loose powder particles has substantially uniform thickness. Step b) includes independently carrying out step a) a number of times to generate an abrasive article preform comprising the bonded powder particles and remaining loose powder particles. Step c) includes separating remaining loose powder particles from the abrasive article preform. Step d) includes heating the abrasive article preform 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. A method of making a metal bond abrasive optionally includes infusing an abrasive article preform with a molten lower melting metal and solidifying the molten lower melting metal to provide the metal bond abrasive article. The present disclosure further provides a vitreous bond abrasive article precursor and a metal bond abrasive article precursor.
