The disclosed sealing film is for surrounding a device for tamper evident protection of the contained device. The scaling film has a backing with a perimeter surrounding a central area and an adhesive on the backing at least at the perimeter of the backing. A tamper evident layer is separably connected to the backing along a substantial portion of the perimeter of the backing. Therefore, attempted peeling, pulling, opening of the sealing film will cause the tamper evident layer to remove from the backing and indicate tampering.

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.

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.
