Abstract Scope |
Additive manufacturing is a rapidly evolving technology in which complex components can be formed directly from a cad model. Unfortunately, these technologies are prone to flaw formation due to the complex laser-material interactions and heating that occurs while the component is being built. Since defect-critical industries are investigating the use of additive manufactured components, it is important to detect the presence of these flaws while the component is being built. Toward this end, numerous sensors have been added to the build chamber of additive manufacturing machines to assess the quality of the build. While these added sensors provide data about the process, often times the physical mechanism that causes the sensor signature is unknown. Here we discuss the relationship of filtered photodiode voltages to physical meltpool and plume parameters e.g. meltpool length. Further, a brief discussion of other sensors and their measurements will be discussed. |
