Abstract: Various embodiments disclosed relate to pore inducers and porous abrasive forms made using the same. In various embodiments, the present invention provides a method of forming a porous abrasive form including heating an abrasive composition including pore inducers to form the porous abrasive form. During the heating the pore inducers in the porous abrasive form reduce in volume to form induced pores in the porous abrasive form.

Abstract: An additive layer manufacturing method, preferably using selective laser sintering, for manufacturing a solid article, the method including applying a layer of a powder, the powder including at least one powdered (co)polymer, onto a solid substrate in a processing chamber; fusing the powder layer onto the solid substrate; subsequently depositing successive layers of the powder, wherein each successive layer is selectively fused prior to deposition of the subsequent layer of powder so as to form the article. In some embodiments, the powder further includes abrasive particles having a hardness greater than or equal to that of aluminum oxide.

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 shaped abrasive agglomerate particle includes a shaped abrasive particle bonded in a vitreous matrix. 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.

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.

Abstract: Methods of making abrasive articles involve adhering shaped abrasive particles to a reinforcing member according to a predetermined pattern and optionally orientation, and depositing a space-filling binder precursor on the reinforcing member and shaped abrasive particles to provide a filled abrasive preform, disposing another reinforcing member onto the filled abrasive preform, and curing the abrasive article precursor to form the abrasive articles. In some aspects, multiple abrasive preforms are stacked on each other. Bonded abrasive wheels preparable according to the methods are also disclosed.
