This book elucidates the fundamental thermomechanical behaviour inherent in the 3D printing process within a laser-based powder bed fusion (L-PBF) system. It presents foundational concepts and provides in-depth derivations of the governing equations. The analysis encompasses arbitrary anisotropic linear viscoelastic materials, accounting for thermal effects. The authors leverage the theory of axially moving materials, a framework previously employed in the analysis of production processes within the process industry. They introduce a coordinate frame that moves in tandem with the printing laser, adopting an Eulerian perspective towards the in-motion solid. Designed for graduate students and researchers, this book is poised to foster a profound comprehension and spur innovative technological advancements in the realm of additive manufacturing.

This book discusses the stability of axially moving materials, which are encountered in process industry applications such as papermaking.

Using analytical and semi-analytical approaches to calculate out-of-plane dynamics and stability, this volume includes new results on fundamental aspects of moving materials that can be applied to industrial processes from paper-making to foil extrusion.
