  TL;DR: normal sand casting, using a microwave to heat up the metal inside an insulated silicon carbide crucible.

    I didn’t know silicon carbide heated up in the microwave. I learned something out of the article.

      I started watching the video on Youtube, but almost immediately switched to an older video from the same guy that went into more detail on the metal-melting part.

      It’s been popular for making ceramics at home in microwaves for years

  …And also breaks instantly as soon as it’s put under load. The process is for sure very interesting, but a simple casting like this is not the correct method for making something like a wrench. It’d be useful for plenty of other parts, though.

    Well, it will work… until it suddenly doesn’t.
