||While the last decade witnessed significant advancements in beam-based additive manufacturing, including powder bed fusion and directed energy deposition, these processes still face critical quality challenges due to their rapid solidification and melting nature, leading to issues like porosity, hot cracking, residual stress, and columnar grain structure. Recently, a new set of solid-state additive manufacturing processes has emerged, which aim to avoid these problems by bonding materials without liquid-to-solid phase transformations. Nonetheless, these solid-state additive processes present their own challenges that require further exploration.
This symposium aims to delve into these challenges and exchange ideas on potential solutions, with a focus on examining the interrelationships among different aspects of solid-state additive manufacturing, e.g., process variables, properties, application performance, economics, and functionality. Processes of interest include but are not limited to cold spray, additive friction stir deposition, ultrasonic additive manufacturing, and sintering-based processes, e.g., binder jetting, material extrusion, and material jetting.
