Many different processing techniques are used to create parts through additive manufacturing including melting or sintering powders, holding powders together with binders, solidifying resins with UV light, and depositing polymer or metal filaments softened using heated nozzles. A relative newcomer to additive manufacturing is electromagnetic control build conditions, mainly through the application of high frequency AC fields. Electromagnetic processing can be used with metals or doped polymers both as a way to provide the needed energy for deposition and to improve lamination strength. Lamination strength can be improved and thermal stresses can be reduced in both metals and doped polymers by reheating deposited material before the next layer is added. Light weight and energy dense electromagnetic emitters are demonstrated on BAAM are shown to exhibit the potential to provide faster, more efficient deposition of directed energy. Mesogenic shape shifting polymers as AM feedstock is discussed along with transient physical properties.
