3Degrees Discussions – Ep. 155 | John Barnes (Additive Nexus)
From South Bend, Indiana—welcome to 3Degrees Discussions. I’m your host, Mike Vasquez. This show digs into the stories behind the innovators, entrepreneurs, and leaders shaping the 3D printing industry.
About this episode
My guest is John Barnes, founder of Additive Nexus, a consultancy that helps heavy industry scale additive manufacturing from pilot to production. John previously led AM initiatives within ExxonMobil’s Technical Computing group, connecting engineering, supply chain, and maintenance to real-world AM use cases. We also get into his work around industry standards and digital inventory—think API 20S/20T frameworks and the broader push to make on-demand, trustworthy spare parts a reality at scale.
What we cover:
Moving from AM pilots to true production in heavy industry
Lessons from deploying AM inside a complex enterprise
Digital inventory, part criticality, and qualification pathways
How API 20S/20T and other standards shape adoption
Building trust in on-demand parts—quality, data, and traceability
