After struggling with the problems with gravity feeding molten glass though a small nozzle (inherent with MIT’s glass printer design), we have decided to redesign our hotend to forcefully extrude molten glass (and other materials).

To that end, our 15KW induction generator is capable of melting most anything at a flip of a switch. It’s seriously like magic! Here are the results from our first run.
