A method of measuring spectral emissivity of materials is provided. The method comprises placing material in a controlled chamber and exposing the material to an energy source to heat the material. At least one multi-wavelength pyrometer measures the spectral emissivity of the material produced by heating by the energy source, wherein the multi-wavelength pyrometer is positioned at a distal end of a tube extending from the chamber, wherein the tube provides a sacrificial surface for vapor condensation to prevent the vapor condensation from obscuring a view port used by the pyrometer.

Spectral emissivity and temperature measurements of metal powders during continuous processing in powder bed fusion additive manufacturing

A method for embedding a line in a substrate. A line embedding head in positioned relative to a surface of the substrate. The line from an output port in the line embedding head is output at an angle relative to the embedding head such that the line is embedded in the substrate.

Wire embedding system with a curved delivery path

An apparatus, system, and method for automatically dispensing and embedding components into three-dimensional parts. In an example embodiment, a direct wire embedding head can be fixed on an automation motion system. The direct wire embedding head begins and terminates an embedded wire pattern on a layer or on a surface of a three-dimensional part in order to automatically create the embedded wire pattern. A sensor is located on an embedding surface wherein the embedded wire pattern is embedded. The sensor can measure the distance between the direct wire embedding head and the embedding surface. A predefined distance can be maintained to ensure successful embedding results for the embedded wire pattern by automatically adjusting a position of the direct wire embedding head in response to feedback from the sensor.
