Vader father and son developing liquid metal 3d printing machine

On a Vader machine, a strand of aluminum is fed into a heat element that melts it at 750 degrees Celsius (1,382 degrees Fahrenheit). The liquefied metal is then passed to a ceramic tube that forms an ejection chamber and has a submillimeter orifice. A magnetic coil surrounds the tube and receives a short-lived electrical pulse to create a pressure within the tube that ejects a droplet of liquid metal through the orifice. The ejected drop is projected downward onto a heated platform that maneuvers to create solid 3-D shapes based on layer-by-layer deposition and the coalescence of the droplets.

Zack Vader said plans are to modify the device, adding nozzles to make it faster. Eventually the machines will be able to melt and print steel at 1,400 C (2,552 F).
