This episode of AM Insider features guest Zeke Sudbury, an additive sales specialist at Atlix, who discusses his professional transition from the world of polymers and composites to metal additive manufacturing (AM). Hosted by Justin Hopkins and Dustin Kloempken, the conversation explores the technical and cultural differences between these two realms, noting that polymer expertise focuses on material science and polymer chains, while metal AM is more akin to welding engineering.

The central theme of the episode is the identification of "boring" but highly profitable applications that drive industry growth. Sudbury argues that while industries like aerospace and medical have long qualification cycles that can slow down progress, the firearm suppressor industry has effectively "saved" metal additive by providing a high-demand application with lower barriers to entry.

Key topics covered in the episode include:

• The Suppressor Case Study: A deep dive into why suppressors are ideal for metal AM. Sudbury explains the thermodynamics behind their design, noting that additive allows for complex internal geometries and "baffles" that increase volume and decrease temperature to reduce external pressure. He also highlights how surface roughness, often viewed as a defect, is actually beneficial for suppressors as it adds turbulence and improves performance.
• Industry Trends and Market Shifts: The discussion covers the recent surge in suppressor demand due to changes in government fees in early 2026 and the adoption of these components by the U.S. Army for hearing protection and toxic gas reduction.
• The Role of AI and Software: How AI and cloud-based software (such as OAM for dental) are lowering the barrier to entry for new users by automating complex tasks like part orientation, support generation, and failure prediction.
• Future Frontiers: Looking beyond suppressors, Sudbury identifies dental, semiconductors (pure nickel printing), and heat exchangers as the next major growth areas for the industry.
• Advice for Professionals: Sudbury emphasizes the importance of networking and "being a sponge" when entering the field. He recommends the Solid Freeform Fabrication Symposium in Austin, Texas, as a premier resource for anyone looking to understand the cutting-edge academic research driving the industry forward.

The episode concludes by emphasizing the importance of the feedback loop between academia, engineering, and sales to solve increasingly complex manufacturing problems.
