Paul writes “DIY benchtop metal casting. Finally. I was doing some research on liquid-metal-cooled CPUs and video cards when I stumbled upon this gem: With the right susceptor/mold materials, you can cast your own bronze, silver, and potentially ferrous metals in a common microwave. A terrific compliment to aforementioned 3D scanners and 3D printers… Or maybe just a great way to save some money by making your own jewelry”. Link.
note from david…
“It is true Y-12 were granted US patent 7011136 for melting metal in a microwave chamber. Their filing date was November 12, 2001. However, this does not predate my article “Melting metals in a microwave” which was first uploaded to the public domain on April 11, 1997. Y-12 were, in fact, forced to cite my article in their patent to gain B2 status. David Reid”
