Regarding the scalability of Additive Friction Stir Deposition (AFSD) for large-scale industrial applications, we previously discussed several critical factors including:
Tool Size and Design
Machine Gantry/Work Envelope
Deposition Rate
Thermal Management
Process Control and Automation
Cost Implications
Quality Assurance
Considering these, which single factor do you deem the most critical for successfully scaling AFSD to large-scale industrial use, and why?
