Experimental Investigation Of Thermal States In Polymer–Ceramic Multi-Material Additive Manufacturing, Jagadeesh Reddy Kanuboddu, Amy Peterson, Alireza Amirkhizi, Christopher J. Hansen

MMRL-XMO Industrial Seminar

Polymer–ceramic multi-material additive manufacturing (MMAM) offers opportunities to combine the complementary properties of polymers and ceramics within a single structure. However, integration of these materials remains challenging because ceramic processing temperatures greatly exceed those tolerated by most polymers, creating the risk of melting or thermal degradation during adjacent ceramic processing. This challenge is particularly important when laser-based ceramic processing is performed in proximity to polymer additive manufacturing processes, including applications involving ceramic powder bed fusion. Understanding transient heat transfer from laser-heated ceramic regions to neighbouring polymer structures is therefore important for the development of practical polymer–ceramic MMAM approaches. Previous thermal …
