Expected Research Outcomes:

  • Identification of optimal FDM process parameters (e.g., nozzle diameter, layer height, infill density, print speed) for M300 TOOL STEEL and Stainless Steel 17-4 filaments, leading to enhanced print quality and mechanical performance.
  • Development of printed parts with superior tensile strength, hardness, and thermal stability, meeting industrial application standards for mechanical integrity and durability.
  • A Bayesian optimization framework tailored for multi-objective problems, enabling efficient trade-offs among conflicting objectives such as mechanical strength, thermal stability, and dimensional accuracy.
  • Reduction in porosity and shrinkage through optimized debinding and sintering processes, resulting in densified printed components with reduced defects.
  • Detailed characterization of the printed parts using standards (e.g., ASTM E18, E8), TGA and SEM, offering insights into thermal and microstructural behavior.
  • Creation of the opportunity for advanced research, foster interdisciplinary collaborations, and provide hands-on learning opportunities for students in cutting-edge manufacturing technologies. By integrating advanced equipment and optimization methodologies.
  • Advancement of SDG 12 and SDG 9 in metal additive manufacturing.
