Burners and additive manufacturing methods

A non-transitory machine-readable medium having data representing a three-dimensional model of a burner body, when accessed by one or more processors interfacing with a 3D printer, cause the 3D printer to create the burner body comprising:

• 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
• 4) 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, wherein the at least one heating element comprises a heating fluid, wherein the at least one heating element further comprises a structure that increases heat transfer, wherein the structure that increases heat transfer comprises individual posts;
• wherein the burner body comprises a plurality of layers of metal directly bonded to each other.

A method, comprising:

• retrieving, from a non-transitory machine-readable medium, data representing a 3D model of a burner body, the burner body comprising:
• 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
• 4) 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, wherein the at least one heating element comprises a heating fluid, wherein the at least one heating element further comprises a structure that increases heat transfer, wherein the structure that increases heat transfer comprises individual posts;
• wherein the burner body comprises a plurality of layers of metal directly bonded to each other;
• executing, by one or more processors, a 3D printing application interfacing with a manufacturing device using the data;
• and
• generating, by the manufacturing device, a physical object of the burner body.

A method of forming a burner body, the method comprising:

• receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying a plurality of layers of a burner body, the burner body comprising:
• 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
• 4) 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, wherein the at least one heating element comprises a heating fluid, wherein the at least one heating element further comprises a structure that increases heat transfer, wherein the structure that increases heat transfer comprises individual posts;
• wherein the burner body comprises a plurality of layers of metal directly bonded to each other;
• and
• generating, with the manufacturing device by an additive manufacturing process, the burner body based on the digital object.

A system comprising:

• 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, the burner body comprising:
• 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
• 4) 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, wherein the at least one heating element comprises a heating fluid, wherein the at least one heating element further comprises a structure that increases heat transfer, wherein the structure that increases heat transfer comprises individual posts;
• wherein the burner body comprises a plurality of layers of metal directly bonded to each other.
