"3d Welding and Milling: Part I–a Direct Approach for Freeform Fabrication of Metallic Prototypes"

  • Steel
  • Heated Bed *possible Cooled bed..Al*
  • Conducted Face Milling
  • Recorded different microstructures at different layers

"3d Welding and Milling: Part Ii—Optimization of the 3d Welding Process Using an Experimental Design Approach

  • Mild Steel
  • Found that the wire feed rate and voltage are more important than the distance from tip and gas concentration
  • Methods to follow: Unidirectional and "Zig Zag"
  • 0.9 mm diameter bead "0.035 inch"
  • Single Bead experiments. Studied parameters
