A colleague of yours has the idea that one could make a Material Jetting system that creates aluminum parts by inkjet-printing molten aluminum. After a brief Google search, you find that molten aluminum has the following properties: Thermal conductivity 237 W/mK Liquid density 2.375 g/cm3 Electrical resistivity 28.2 nm Viscosity 14 cP Surface tension 530x10-3 N/m Melting point 660.32 C Half-life 7.17x105 years Boiling point 2519 C MSE 228 Additive Manufacturing Exam 7 Assuming you would use a heated piezo-driven drop-on-demand inkjet printer (with nozzle diameter of ~60 m), prove to your friend why this is or isn't a feasible idea. (Note: 1 cP = 102 P = 103 Pas = 1 mPas; 1 n = 1x10-9 )
