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.

Additive layer manufacturing method and articles

Metal bond abrasive articles and methods of making metal bond abrasive articles via a focused beam are disclosed. In an aspect, a metal bond abrasive article includes a metallic binder material having abrasive particles retained therein, where the abrasive particles have at least one coating disposed thereon. The coating includes a metal, a metal oxide, a metal carbide, a metal nitride, a metalloid, or combinations thereof, and the at least one coating has an average thickness of 0.5 micrometers or greater. The metal bond abrasive article includes a number of layers directly bonded to each other. Metal bond abrasive articles prepared by the method can include abrasive articles having arcuate or tortuous cooling channels, abrasive segments, abrasive wheels, and rotary dental tools. Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying a metal bond abrasive article; and generating, with the manufacturing device by an additive manufacturing process, the metal bond abrasive article based on the digital object. A system is also provided, including a display that displays a 3D model of a metal bond abrasive article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of the metal bond abrasive article.
