  • Optical powder spreadability sensor and methods for powder-based additive manufacturing
    Patent number: 11426940
    Abstract: Disclosed is an apparatus for and method of determining spreading behavior of a powder material during an additive manufacturing process. The method deposits a powder mound, moves a spreader to distribute a layer of powder over a build supported on a build area, operates an energy source to cast intercept the powder mound in the path of the source and onto an optical sensor during displacement of the powder mound, and analyzes an output of the optical sensor to identify features relating to the spreading behavior of the powder.
    Type: Grant
