Overview

This investigation demonstrates the impact of printing parameters on material properties in binder jet printed WC-Co, indicating potential for complex geometries.

Key Points

  • This research aims to analyze how different printing parameters affect the densities and properties of binder jet printed WC-Co materials.
  • Utilized binder jet printing for un-sintered WC-Co powder
  • Employed a systematic design of experiments approach
  • Examined various print parameters including binder saturation and drying time
  • Measured green and sintered densities along with hardness and porosity
  • Achieved a maximum sintered density of 97.8%
  • Measured Vickers hardness at 1310.4 HV
  • Found high porosity in green samples leading to increased indentation fracture toughness and magnetic saturation
