It uses molten metal and jets it in small droplets onto a surface similary to a standard inkjet paper printer and by connecting the metal droplets a 3d object can be made. It could be considered world’s first molten metal 3d printer!
Since one of the design ideas behind this machine is to make it widely available, the material it uses had to be widely available and cheap so the main material is molten aluminum wire.
Vader is founded two years ago by Scott and Zachary Vader, a father-son team. With Fall of 2015 being the timeframe for the release of first working pre-production Mark 1 prototype.
The price range of the first machine should be around 250.000 USD which is much cheaper than currently available commercial metal 3d printers.
Hopefully the Vader team will be successful in bringing their machine to the market and start the race for affordable HOME metal 3d printers. I want one! And I know some of you want one too!
