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.

Burners and additive manufacturing methods

A membrane having a first outer surface having a plurality of pores in a skin layer and the plurality of pores having a closed perimeter in the skin layer. The membrane having a second outer surface and a porous supporting layer connecting the first outer surface to the second outer surface. The first outer surface of the membrane is a melt-fused skin layer from exposure to ultra-violet light.

An article () has a polyester film backing () and a primer layer () including a carboxylated styrene butadiene copolymer crosslinked with a polyfunctional aziridine disposed on a major surface of the polyester film backing (). Another article includes a polyester backing (), a primer layer () including a carboxylated styrene butadiene copolymer crosslinked with a polyfunctional aziridine disposed on a major surface of the polyester backing (), and a phenolic layer () disposed on the primer layer () on a surface opposite the polyester backing (). The phenolic layer () can include abrasive particles (). Processes for making the articles are also described, as well as methods for abrading a workpiece and improving adhesion between a polyester film backing () and a phenolic layer () on the polyester backing ().
