    Abstract: A vacuum molding roll sleeve (100, 700, 800)comprises a body (119, 818, 819) comprising a mold wall portion (120, 820) disposed between a molding surface (110, 1210, 710, 810) and at least one vacuum surface (130, 830). The molding surface (110, 1210, 710, 810) has shaped depressed features and has first openings (112, 812) disposed therein at first predetermined positions (134). Each first opening (112, 812) is spaced apart from the at least one vacuum surface (130, 830) by a respective minimum thickness (135, 835). The at least one vacuum surface (130, 830) has second openings (132, 832) disposed therein at second predetermined positions (134). The first openings (112, 812) are fluidly connected to the second openings (132, 832) by conduits (140, 840) wherein, on a respective basis, at least some of the conduits (140, 840) are longer than the minimum thickness (135, 835) between the first openings (112, 812) and the vacuum surface (130, 830). The vacuum molding roll sleeve (100, 700, 800) is configured such that at least partial vacuum can be applied to the first openings (112, 812) through the conduits (140, 840) fluidly connected thereto. The vacuum molding roll sleeve (100, 700, 800) is mountable on a backup roll (737). Methods of making and using the vacuum molding sleeve are also disclosed.

    Abstract: Burners and methods of making burner bodies via a focused beam are disclosed. In an aspect, a burner includes (a) a burner body and (b) at least one connector configured to supply at least a fuel and an oxidizer to the burner body. The burner body includes (1) a plurality of passageways; (2) a first major surface; (3) a plurality of ports at the first major surface, each port defined by an end of one of the passageways; and either: (4a) at least one heating element in or adjacent to at least one of the plurality of passageways that increases the temperature of a wall of the at least one of the plurality of passageways; or (4b) a cooling chamber directly adjacent to three or more of the plurality of passageways. The burner body includes a number of layers of metal directly bonded to each other. Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying a burner body; and generating, with the manufacturing device by an additive manufacturing process, the burner body based on the digital object. A system is also provided, including a display that displays a 3D model of a burner body; 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 burner body.

    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.
