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.

As the Head of Technology at GKN Aerospace, Laura developed the strategic skills required to affect technological change in large organizations. This includes translating technical roadmaps into strategic business visions and vice versa, building businesses cases, securing capital and operating funding (~$15M OpEx and ~$7M CapEx over 4 years), protecting and exploiting Intellectual Property, and collaborating across the industrial supply chain. Laura’s leadership skills are highlighted through her ability to build and enable diverse teams; she was responsible for the build out of a new team focused on the maturation of laser/wire deposition for Titanium aerostructures after negotiating a CRADA between GKN Aerospace and Oak Ridge National Laboratory, valued at $18M over 5 years.
Laura has a passion for optimizing manufacturing processes. For 15 years, she has focused on improving metallic alloys and processes, specifically for laser/wire deposition, friction stir welding, spin forming, machining, and various wrought processes with application to Titanium aerostructures, Aluminum wing skins and inlet lip skins, and Copper electrical connectors, coinage, and ammunition. She directly supported aerospace production including Boeing’s 787-9, F/A-18 and F-15. Her enthusiasm for additive manufacturing and promoting diversity in the workplace is contagious, and Laura shares her energy via various public forums, ranging from executive aerospace conferences to university lectures to kindergarten classrooms. Laura graduated summa cum laude with her B.S. in Metallurgical Engineering from the University of Missouri – Rolla (now Missouri S&T).
