SMR 3D Printing Production Support Center Co-Hosts WAAM Commercialization Symposium in Changwon on May 13

The Korean Welding and Joining Society's Additive Manufacturing Research Committee and the SMR 3D Printing Production Support Center will jointly host the 'WAAM-Based Metal Additive Manufacturing Demonstration and Commercialization Strategy Symposium' on May 13, 2026, at the Changwon Convention Center in Gyeongnam, South Korea. Organized by the 3D Printing Research Association, the event expects approximately 200 attendees from industry, academia, and government. The symposium will cover AI and robot-based process integration, defense product localization, quality certification, and standardization, with dedicated sessions on SMR (small modular reactor), aerospace, defense, and shipbuilding applications. Presenters include the Korea Institute of Materials Science, the Korea Institute of Industrial Technology, and domestic and international WAAM companies.

This event marks a deliberate shift from technology introduction to commercialization conditions in WAAM, a DED process that uses electric arc heat to melt metal wire layer by layer for large-scale components. The symposium's focus on SMR, nuclear fusion, and defense aligns with South Korea's strategic push to localize critical supply chains under the broader 'Korean New Deal' industrial policy. WAAM competes with LPBF for large-format metal parts but offers faster deposition rates and lower capital costs, though it typically requires post-machining. The explicit inclusion of certification roadmaps and quality prediction technology signals that the industry recognizes the aerospace qualification grind and defense certification barriers as the primary bottlenecks to serial production, not the deposition technology itself.

From an expert standpoint, this symposium is a practical step toward closing the gap between WAAM's technical capability and its commercial viability in high-value verticals. The organizers are correct to prioritize certification frameworks and end-user engagement over further process refinement. The real test will be whether the participating research institutes and companies can translate these discussions into binding qualification protocols and actual procurement contracts with Korean shipbuilders, defense primes, and nuclear energy contractors within the next 12 to 18 months.
