Metal AM Utilization

Working with Physical Sciences Inc., I developed a comprehensive simulation system to optimize the utilization of their high-value Nikon SLM metal 3D printer. The printer was experiencing significant downtime between jobs due to inefficient workflow management and buffer sizing issues.

Approach & Solution

I modeled the entire post-processing machine line (SLM, band saw, mill) as unreliable with buffers and simulated various workflows to determine ideal buffer sizes. This Python-based simulation accounted for machine reliability, processing time variations, and job scheduling constraints.

Outcome & Results

Through careful analysis and optimization, the simulation recommended buffer configurations and job scheduling strategies that improved projected utilization from approximately 20% to 50%. I also delivered standard operating procedures (SOPs), live spreadsheets, and simulation tools for PSI implementation.
