Fundamentals of Laser Powder Bed Fusion of Metals. Additive Manufacturing Materials and Technologies

  • ID: 5230612
  • Book
  • June 2021
  • 500 Pages
  • Elsevier Science and Technology

Fundamentals of Laser Powder Bed Fusion of Metals provides new users and students in the additive manufacturing field the fundamentals on laser powder bed fusion of metals-the most widely used form of this advanced technology. Current best practices are discussed in detail, including technology limitations and challenges. Covering the latest advancements in the field, this book serves as a useful reference for senior researchers and engineers in industry. After years of research and development of this manufacturing technique, we are now at the brink of a new era in additive manufacturing, which supports the 4th industrial revolution.

Laser powder bed fusion of metals is a technology that makes use of a laser beam to selectively melt a powder layer and build a 3D part directly in metal. This is a revolutionary and disruptive manufacturing technology, which is reaching maturity and opening great opportunities for new designs and production of complex functional end-use products with excellent properties and even mission-critical components.

  • Presents laser process bed fusion fundamentals, as well as their inherent challenges
  • Provides an up-to-date summary of this advancing technology and its potential
  • Provides a comprehensive textbook for universities, as well as an introductory reference for individuals in industry who are starting in this dynamic field
