    17-Year-Old Created a 3D Metal Printer

    A 17-year-old named Sagar has created a 3D printer capable of printing in metal. Currently it is restricted to using solder, but he plans on experimenting with different materials, and eventually releasing an extruder on Kickstarter for around $150. The extruder would be able to handle the process of extruding metal filament. While this is a long way off from allow us to print in a large variety of metals, hopefully with some material engineering we will one day see more options become available.

    Nice. I hope he makes something out of it.

    Did this ever start up?

    Did Sagar solve the extruder problem and work out the equation regarding the melting point on the alloys?
    What about the nozzle issue?
    Does anyone have information on the current status of this invention?

    I'm going to have to look around for this a bit. Very cool.
    Five bucks says he was using rosin-core (flux) solder and it ate away a brass extruder tip because the orifice is so hot, and the flux is acidic.

    Probably the most important to emphasis:

    -He is in the process of creating a 3D printer, more specifically a 3D printer extruder, that is capable of printing using metal filament.

    -He based his idea on that of traditional FDM 3D printers – the ones that print in plastics, by melting and extruding molten PLA or ABS. He simply replaced the plastic with a metal alloy (solder), which consists mainly of tin (95.8% tin, 4% copper, and 0.2% silver).


    I can tell you he will have hard time with the oxidize layer that wont bond at all. Any people with basic soldering in electronics knows it is a pain in the butt to deal with oxide layers that prevent the solder forming a bond. But then even if he succeed making a bond, I will call hardly "3D printing".

    Why would you not consider it 3d printing? You consider fdm 3d printing and this is exactly the same process just with a different filament. So what's the difference?
