Abstract: An oriented heat-treated principal film capable of thermally-induced self-forming, including one or more (co)polymers and exhibiting a relaxation temperature (Tr), the oriented heat-treated principal film having opposed first and second major faces, a land portion on the second major face and one or more modification zones on the second major face. A cross-linked (co)polymeric carrier layer is in contact with the first major face. Each modification zone includes a central closed portion and a rim portion surrounding the central closed portion and being surrounded by a land portion. An average thickness of each rim portion is greater than an average thickness of the land portion surrounding the central closed portion.

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: An article has first and second substrates with a spacer between them. The spacer includes beams connecting a plurality of walls, with openings between the beams. The plurality of walls includes multiple first, second, and third portions. The first and second portions are not parallel and have top and bottom edges that define a height of the wall and contact the first and second substrates, respectively. The third portions have top edges continuous with the top edges of the first and second portions but a smaller height than the height of the wall. At a given plane intersecting a first or second portion and perpendicular to the top and bottom edges, the thickness of at the top edge is plus or minus ten percent of the thickness at the bottom edge. The third portions are connected with some of the beams connecting the walls.

Abstract: A heat-treated non-oriented principal film including a cast (co)polymeric component that is not capable of thermally-induced self-forming. The heat-treated principal film has first and second opposed major faces and at least one modification zone on the first major face, each modification zone including a central portion and a rim portion surrounding the central portion. Each rim portion is surrounded by a land portion. An average thickness of each rim portion is greater than an average thickness of the land portion surrounding each modification zone, and an average thickness of each central portion is less than the average thickness of the land portion, or zero. The first major face of the heat-treated principal film may be positioned in contact with an oriented carrier film including a molecularly-oriented (co)polymer that exhibits a relaxation temperature (Tr). Methods of making such films and hand-tearable adhesive articles including such films are also disclosed.
