Transformative Frontiers in Additive Manufacturing

Additive manufacturing (AM) provides a resource-conscious and more sustainable alternative to traditional machining where raw materials are cut and trimmed to produce parts. In particular, 3D printing is a disruptive AM technique where complex 3D parts can be produced point by point, line by line, or layer by layer according to a digital design. Rapid development of AM in the last decade has led to emerging applications that take advantage of its unique geometric control, production flexibility, and materials utilization efficiency. This Special Topic aims to highlight the advancing frontiers of additive manufacturing that could potentially transform manufacturing. Among diverse topics, this collection calls for submissions that examine physics-driven fundamental understanding that governs AM processes, in situ diagnostics that improve AM quality and productivity, and
co-design of AM technologies with emerging application cases.
