Benefits of In-situ Monitoring in Metal Additive Manufacturing
In metal AM, in-process monitoring can enable and accelerate the roadmap to qualification and certification by monitoring and analyzing data and exploiting that data to create repeatability. There are many choices when it comes to variables during the initial development stages. These may include the materials, geometry, and initial development parameters. Having real-time data on the melt pool, the material, the laser, and data on a layer-by-layer basis can quantify the variables within directed energy deposition (DED) and the DED process itself. Join FormAlloy as we discuss the several in-situ monitoring and control features used within the DED industry and how they improve the end-user’s experience with the metal AM technology.

3D Line Confocal Imaging: Optical Surface Roughness and Texture Characterization Technology for In-process Finish Metrology and Inspection Applications
This presentation introduces LMI’s unique 3D Line Confocal Imaging (LCI) technology that was developed to characterize microtopographic features of challenging surfaces at sub-micron resolution. Well-suited applications for this method include matte, high-gloss, clear and high-contrast surfaces with finishes made from any material type sensors, and surface roughness measurement systems based on them, are fast and can be used to scan surfaces moving at the speed of up to 500 ft. per minute. A bench-top laboratory scanner based on the same sensor technology is available as well. Operational principle of the line confocal imaging method and its strengths and limitations are discussed. Various surface roughness and texture inspection applications are explored, including polymer and metal finishes.
