John O. Milewski received his B.S. in Computer Engineering from the University of New Mexico and his M.S. in Electrical Engineering from Vanderbilt University. He began his technical career with five years' metal fabrication experience ranging from heavy industry production as an ASME code welder to light manufacturing and applied research. He spent 32 years at Los Alamos National Laboratory, in positions including Welding Technologist, Engineer, Team Leader, Experimental Component Fabrication Program Manager, and Group Leader for Manufacturing Capability. He is currently retired from the Lab, writing and consulting as APEX3D LLC regarding the new and exciting applications of AM technology.

His technical expertise includes arc systems electron beam, laser welding, robotics, sensing and controls, and the joining of less common metals. His work experience also includes CAD/CAM/CNC model based engineering, process modeling, and simulation with validation methods to include residual stress measurement. In addition, he served 2 years in the late 1980s as Vice President of Synthemet Corporation, an entrepreneurial high tech start-up, with the goal of development and commercialization of 3D additive manufacturing of metals. 

He is author and co-author of numerous publications related to high energy beam processing and process modeling. His awards include an R&D 100 Award for Directed Light Fabrication, Fellow of the American Welding Society (AWS) and the AWS Robert L. Peaslee Award. He is inventor or co-inventor for a number of patents related to laser welding and additive manufacturing. 

He has had extensive formal collaborations with universities and sponsored students resulting in refereed publication and patenting. His professional society involvement included Chairman, Co-Chairman, and advisor of AWS committees related to High Energy Beam, Electron Beam, and Laser Beam Welding. In addition, he currently serves as an

"This book is dedicated to the special aspects valid for metals. ... The fresh writing style, sometimes more like a storyteller, makes reading these many facts quite easy and understandable. ... The interested reader can get a Jot of information about the topics one should deal with when working with additively manufactured metallic parts. lt gives a general roadmap where to start, what to learn and how it fits together." (Ralph Bäßler, Materials and Corrosion, Vol. 69 (12), December, 2018)

"This book ... covers subjects from fundamental technology to rocket nozzles, medical implants, and custom jewelry. The author shares a multitude of useful footnotes and pages of references at the end. Also included are practical appendices for users. ... I can heartedly recommend this book as a valuable reference and a good read for all interested in additive manufacturing."
