John E. Barnes - Founder and Managing Director
John has a 25+ year career in product development and aerospace with Honeywell, Lockheed Martin Skunk Works™, Australia’s CSIRO, and Arconic (formerly Alcoa and RTI International Metals). He’s been involved in metal additive manufacturing throughout this career beginning in the late 1990s where he was part of the Sandia National Labs LENS™ CRADA. Since then, he has been in and around AM working both technical and business cases for implementation and development efforts in materials, powders, processing, and printing to mature the technology for applications. John is recognized internationally for contributions to additive manufacturing, product development, and leadership in engineering. His groups boast world firsts in medical, therapeutic, and aerospace additive manufacturing. John is a Materials Engineer by background but has developed expertise in manufacturing, airframe structures, gas turbines and low observables. He is currently an Adjunct Professor at RMIT University, and an Adjunct Senior Research Fellow at Monash University, both in Melbourne, Australia. In 2014, he was Purdue University’s Materials Engineer of the Year, and in 2017, he was invited to join the Additive Manufacturing Technical Community as a SME Advisor based upon active industry contributions, reputation, and personal commitment to expand the use of additive manufacturing.

Dr. Slattery was most recently the Chief Scientist for Additive Manufacturing in Boeing Research and Technology (BR&T). He was responsible for developing and integrating the technical roadmaps and development plans for metallics AM for the entire company, along with building and leading a multi-skilled team to execute and deliver the technology throughout the enterprise. Prior to that, he was the Chief Scientist for Metals, Ceramics, and Mechanical Systems in BR&T, with responsibility for portfolio development and coordination, while executing the additive manufacturing portion. He served at the Division Chief Engineer for USN & USAF fighters and US Army rotorcraft in Boeing’s Military Sustainment organization, including international operators. From 1997 to 2012, he was on the BR&T Metals Team as a researcher and senior manager, where he primarily developed advanced low-cost titanium processing technologies supporting all Boeing products. He was the technical and programmatic lead in implementing the first in aerospace metal additive manufactured structural aircraft components for both spares and production, along with 5 other first in the industry technology implementations. Kevin currently holds 34 US patents, with another 15 applications pending. Kevin has B.S. and M.S. degrees in Metallurgical Engineering from University of Missouri-Rolla (now Missouri S&T), and a DSc in Material Science and Engineering from Washington University in St. Louis.
