Light scattering measurements to support real-time monitoring and closed-loop control of aerosol jet printing

Process monitoring and control is highly desired for additive manufacturing technologies. For aerosol jet printing, in particular, process drift and batch-to-batch variability have hindered widespread adoption beyond research environments. Addressing these key challenges is critical for emerging applications in multilayer, conformal, and 3D applications of this technology. Here, an in situ light scattering method is introduced to track the...
