38 Metal AM as Production Technology – Concerns, Perspective and Parts
As Metal Additive Manufacturing (AM) matures, its role is shifting from prototyping to full-scale production. This transition brings both opportunities and challenges. In this presentation, we explore the practical implementation of Metal AM technologies—specifically Selective Laser Melting (SLM) and Metal Binder Jetting (MBJ)—within a production context.
The focus is on three key areas:
- Concerns – including process stability, quality assurance, and the need for robust monitoring and control systems.
- Perspective – how Metal AM fits into a broader manufacturing strategy, including design freedom, supply chain implications, and sustainability.
- Part – case examples of functional pump parts produced using AM, highlighting the development in part requirements and quality control from spare parts and production tools to end components.
Utilizing both Selective Laser Melting (SLM) and Metal Binder Jetting (MBJ) for component production has revealed the necessity of developing technology-specific frameworks for process monitoring and control. Each method presents unique challenges in terms of material behaviour and post-processing requirements, which directly influence how quality assurance and quality control (QA/QC) must be structured.
For SLM, real-time monitoring of laser parameters, melt pool characteristics, and layer integrity is critical to ensuring dimensional accuracy and mechanical performance. In contrast, MBJ demands precise control over binder deposition, powder bed uniformity, and sintering profiles, with a heavier reliance on post-process inspection and statistical validation.
The presentation aims to provide a realistic perspective on what it takes to move Metal AM from prototype to production.
