This book imparts critical knowledge and insights essential for the innovation of new materials through metal 3D printing. It emphasizes the scientific principles necessary for understanding the substantial temperature gradients inherent in powder bed fusion-type additive manufacturing (AM), highlighting crystallization and crystal growth within super-thermal environments. Furthermore, it introduces pioneering research on material creation grounded in these scientific principles. The text also offers practical guidelines for Neo 3D Printing, facilitating the simultaneous management of crystal orientation and microstructure—pivotal determinants of material properties—during the 3D printing process.

As an indispensable guidebook for materials scientists and researchers dedicated to the development of novel materials, it also serves as an invaluable resource for engineers employing 3D printing technologies to confront challenges associated with materials science.

Parts of this book's translation from its Japanese original manuscript were completed with the assistance of artificial intelligence. The author subsequently revised the content.
