Consumer-grade 3D printing is good for prototyping and making relatively soft plastic stuff. If you wanna make tough things, though, it’s really hard to beat the strength of metal. [Shake the…
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.
TL;DR: normal sand casting, using a microwave to heat up the metal inside an insulated silicon carbide crucible.
It’s not, like, using the microwave to sinter a metal-powder 3D print or anything special like that.
I didn’t know silicon carbide heated up in the microwave. I learned something from the article.
People often make rubies in microwaves. Microwave crucibles can get exceptionally hot.
